Although solar power is available in all parts of the world, there are millions of people across continents that still do not have proper access to electricity. Many communities & villages have never ever been connected to a grid. Most of these people do not even know that the government is supposed to supply them electricity. Solar system for homes can however make this possible.
What is a Solar DC System?
Solar DC systems typically consist of solar panels, charge controller, small batteries, mobile charging port, LED lights & fans which run on DC. Sunlight which falls on solar panels generates DC electricity which goes through charge controller in order to power DC lights & fans. Moreover, solar DC system provides for storing excessive power in batteries. Rural households do not require heavy power loads. Therefore solar DC systems can prove to be an ideal solar system for homes. For areas where the grid is partly available & are prone to extensive power cuts, solar DC systems can charge batteries via grid as well.
Are Solar DC Systems Cost & Energy Efficient?
Yes & for a variety of reasons. Firstly, solar DC systems are attached to lights, fans & charging ports which run on DC. Therefore there are no losses which are associated with conversion. Moreover, solar LED lights also enjoy a long life. Solar LED lights can typically go on for about 3,000 hours & which is just about 4 times more than an average tube light does. Compare this with common inverters. In a common scenario when solar panel makes DC electricity, it goes to the inverter & converts into AC because home appliances which run on grid supply run on AC power. It is in this conversion process that a lot of energy is lost. In short, home solar power systems which run on DC are therefore not just cost-effective but energy efficient as well.
Rural Areas Will be Happy Using Solar DC Systems
Customized solar DC system solutions are also available for individual requirements. Home solar power systems are a great boon for houses that have never been electrified. There is a great demand for solar DC systems throughout the globe in rural areas & other small towns where frequent & lengthy power cuts have troubled people for long. Thanks to these solar systems for home, it is such a delight to see houses that have never had electricity enjoy 24/7 green energy.
Future of Solar DC Systems
With the advent of solar DC systems, solar system for home has a great future especially in rural areas. Rural homes & small shops can now breathe a sigh of relief. Solar DC systems are also affordable & helpful for rural families make their own electricity. Governments across the world, especially the poor third world countries, can take initiative & empower their citizens with help of this golden opportunity.
InteliZon is Shaping the Future of Solar Lighting
Solar PV has emerged as a great source of decentralized power producing DC energy. Alongside this, batteries have emerged as a wide-spread energy storage system which can charge or discharge DC power. Choice of DC voltage is quite important & should be carefully considered for making it a standard. InteliZon understands that energy should be clean, reliable & affordable. Technologies like solar, LED & advanced electronics are the future of energy. Solar energy is a precursor of inclusive growth & the rural population is looking forward to embracing this opportunity. InteliZon is making this possible by creating industry-leading cost-efficient products for harnessing & utilizing this best clean energy.
It is a fact of modern living that all households, institutes & industries require continuous & regular access to power for various reasons. With intermittent or absolutely no grid electricity, solar rooftop systems are now being designed for providing electricity to homes, offices & factories. Moreover, since solar rooftop systems are modular & involve construction, they can effectively be customized for generating & providing solutions which are specifically based on individual requirements.
Decisive Factors for Solar Rooftops
- Rooftop Area – Rooftop area which is available for solar panel is one of the deciding factors. However, most factories would have enough rooftop area for housing a solar PV plant which can meet a substantial portion of their power requirements. Ample space which is available in almost all roofs covering industrial sheds can be productively utilized for generation of solar energy. Home solar power system is another feasible solution which are available as off-grid or grid-tie modules.
- Load Requirements – There are lot of intensive processes like manufacturing, assembling, processing & repairing which the working of industries address. Most of these works are supported very high level of energy consumption involving chillers, compressors, motors & others. It is therefore quite critical to identify which type of loads can be effectively supported by solar power generation.
- Factory Timings – This is another aspect which is important since most factories work in shifts & would therefore also need power during the night time when solar PV plants may not be able to support their requirements. This is why a thorough cost benefit analysis of solar rooftop systems along with energy storage solutions needs to be prepared at the start itself.
Ideal Benefits of Solar Rooftop Systems
Depending upon the type of application, there are several benefits associated with solar rooftop systems. Although benefits may differ depending whether it is required for residential, commercial or industrial purposes, some of the key aspects are enumerated below.
- Financial Benefits – Saving over electricity bills is assured with switching for solar energy. As per studies conducted, minimum savings start at 10 percent & can lead up to 40 percent as well. More Savings on energy with solar power eventually translates to More Earning!
- Green Efficient Buildings – By using solar rooftop systems for commercial or industrial facilities you can pass these benefits to business prospects too. Several companies from all around the world are moving to solar energy & preferring partnering other companies which are also environment friendly. You too can add a message in your company profile claiming that certain amount of your energy requirements are met through solar rooftop plant & the percentage of carbon emission you are able to save due to this.
- Saving Environment – By using solar power, you are reducing power consumption which you would have used from the power company. Power companies commonly use coal or non-renewable energy resources for generating power. With help of solar energy you are using less energy from the grid, which in turn means that you are saving non-renewable energy resources.
- Predictable Power Tariff – Expense on solar energy is quite predictable & may remain such for decades. On the other side, your grid or power company rates are bound to go up over the next 20 years. Your solar energy provider can give you a breakup of the fixed costs & estimates of routine maintenance & repair expenses.

Their primary concern along the border being security, the armed forces suffer bad weather, inedible food, connectivity issues, power cuts, unsafe living conditions and many more. More specifically, the army and the national boundaries are vulnerable to intruders and terrorist activities. Having outdoor lights that stay lit throughout the night is of paramount importance. A single power cut could make them turn into sitting ducks for the enemy to attack. Hence their security is compromised when power cut prevails at night.
There are many burdens of using the conventional lead acid battery based outdoor lighting solutions. It requires high maintenance and lengthy cabling along with being connected to the grid which extremely difficult in remote outposts. The traditional lights also have to be regular cleaned and mounted back on the poles which takes an immense amount of effort from the troops. Maintaining a single outdoor light can already seem like an inconvenience; imagine having to regularly clean and maintain hundreds of lights for too many kilometres along the border. These are the reasons why traditional lights are rendered an additional burden for border security.
Light up the Border with Zonstreet
Intelizon’s channel partner in Jammu & Kashmir sketched a plan and decided to take positive action in helping out our national protectors. He contacted the authorities and introduced them to the reliable outdoor lighting solution, the Zonstreet. It is the perfect off-grid solution that is resistant to extreme weather as well as immune to short circuits, power cuts and unexpected grid failures. The system requires low maintenance and zero cabling. It has the power to efficiently use solar energy and run indefinitely by automatically turning on and off during dawn and dusk respectively. It is the perfect outdoor lighting solution for the army.
Here’s What the Jawans Have to Say
The jawans were might impressed by the lithium ion technology that can survive the harsh border conditions with minimal maintenance. The system is tough; really tough. The jawans were amazed by its performance rarely needing any sort of maintenance. One of the commanders commented to our channel partner, “Zonstreet is perfect yaar! We don’t need to waste our time with maintaining bad lights anymore. Now even we feel protected as the lights never fail to turn on even when there are any power cuts. It is completely independent and helps us continue doing our job safely.” What was extremely useful for the border force was the automatic On/Off feature which controls the lighting system automatically at the correct time every day. The self autonomy feature also helps the light run for longer hours with enough battery backup at all times. The Northern regions face a lot of cloud and foggy conditions due to the mountains but the Zonstreet runs perfectly well even on partial charging.
A New Friend – A New Protector
The initial order for the solar lights was for 20 units. As the jawans got used to the lights, they became a part of their everyday life and they were ever grateful for having technology that so helpful to them in the conflict zones. The next orders increased in volumes and the Zonstreet was installed at many more boundary walls, children’s parks, cantonment gates and premises. It is a matter of pride for Intelizon Energy to have the privilege of serving the protectors of the nation in their times of need.
Join the growing list of Zonstreet customers whose simple feedback is – ‘It keeps working!’
The Zonstreet boasts of a superior protection with the IP65 casing. Being enclosed in the IP-65 casing affords the product and its users a whole host of advantages. But what exactly is the IP65? Jargon is never helpful for regular consumers of any product and so with the Zonstreet as well. Let’s discuss what exactly IP65 means and how it is useful in enabling outdoor solar lighting technology run better. Here is a quick description of the expression and its use in the protection of the Zonstreet.
What is IP?
It is the abbreviation for International Protection Marking and sometimes Ingress Protection Marking which rates and classifies the degrees of protection. It accurately quantifies the level of protection of any product instead of generic terms such as waterproof and dust resistant. Besides the letters, the first digit indicates the level of dust protection and the second indicates liquid protection. For example, an umbrella can be rated as IP01 and a tent as IP42. A submarine on the other end of the spectrum is rated as IP 68 which is completely impregnable by external particles.
How protective is IP65?
An IP65 enclosure is perfect for an electronic item such as the Zonstreet which is exposed to the natural elements for many years. IP65 rated products are protected against water jets. There is not harmful effect on the system with water being projected at the enclosure by a nozzle from any direction. The test duration lasts at least 15 minutes with 12.5 litres of water projected per minute. The maximum pressure generated at this rate from a distance of 3 metres is 30 kPa. That is incredible protection for the system.
Advantages of IP65 Enclosure in the Zonstreet
The protective casing on the Zonstreet is made of certified cable gland and polyamide material. Theft is a common problem among outdoor solar lighting and is solved by the enclosure. The compact Lithium-Ion battery pack is securely built into the system and is impregnable making it thoroughly theft proof. It is also weather resistant and stays unaffected by stormy days or an extensive monsoon season.
The IP65 casing is a big advantage in the Zonstreet which adds many years to the lifetime of the system by cutting maintenance costs completely
Traditional Community Lighting
The traditional grid based light is generally a 35/40 W CFL/tube light IP54 fixture which is mounted on a 4 to 6 metre pole with power consumption of up to 48W. It needs extensive underground cabling from the mains to the light pole with the inevitable grounding. The cost of this underground cabling amounts to about Rs. 8 lakhs and the cost of the pole and its fittings comes up to Rs. 3 lakhs. The luminaire comes at an average cost of about Rs 2 lakhs and lasts for about 4000 to 5000 hours which is a little over 6 months. The luminaire being replaced twice a year is also a huge cost.
Furthermore, the entire unit even after installation poses many drawbacks to the community. Power cuts render the lighting units useless and pose a security threat. To continue using the lighting solution during a grid failure or any issues as such, it would have to be connected to a generator which increases the costs significantly even if it’s temporary. It shuts off at low voltages of 150 V and endures damage at high voltages of around 300 V.
Inbuilt Lithium Ion Based Solar Lighting
One of the biggest advantages of the lithium ion based lighting is that it is self sufficient and money invested in a single unit can be considered as a one time investment with minimal maintenance in the future. The L1 and L2 community lighting solutions are the flagship products by Intelizon and they have similar luminosity to traditional lighting. Their purchase costs are Rs. 13 lakhs and Rs. 16 lakhs respectively. Their lux stands at 12 and 21 units for 6 metres. Their durability is high and have been proven to last for over 5 years with minimum issues in the unit or in terms of maintenance.
While the traditional lights may have operating/maintenance costs at Rs. 16 lakhs, the Intelizon solar lighting solutions cost merely Rs. 10 to 12 lakhs. There is a significant amount of money saved due to the battery of the luminaire deriving its power from the solar panel attached to the pole. Over the years, this cost amounts to a large sum. The solar panels are LM certified high quality units that can last for over 25 years with about 30% degradation in the first 10 to 15 years. They stay off grid and avoid massive maintenance costs too. Even on cloudy days the intelligent technology in the luminaire is able to conserve energy and sustain itself over a longer period of time until more sunlight can be available. The inbuilt sensor is also programmed to increase brightness when approached by someone. This is crucial in remote areas like villages and wildlife resorts which have huge security risks like snakes.
A Clear Winner
Without a doubt, Intelizon’s lithium ion based solar lighting solutions outperform the traditional community lighting solutions by a big margin. The Return on Investment (ROI) is immediate if you factor in cabling costs of the traditional lights. And it may go up due to the savings on grid and cable maintenance, renewable power source optimised lighting during cloudy days and high quality lighting with the lowest cost of ownership.
In short, the lithium ion based solar lighting by Intelizon is the future and it is considerably more economical to acquire than traditional community lighting with all its drawbacks.
The ‘Light Up a Village Initiative’ was a huge success in West Africa. It was powered by Intelizon’s partner in the region, Comafrique. Intelizon’s flagship product in West Africa at the time, the Zonbulb, became a highly desired commodity for rural homes in Gambia and other countries in the region. Intelizon became a household name. Homes stayed lit at night increasing their productivity and giving kids more time to study. Overall, it affected the people’s lives in a big way and showed them the road to a better future. While the homes were well-lit, the street lights on the other hand were still prone to a multitude of issues. This meant that the streetlights routinely stopped serving their purpose.Another Problem to Solve for Intelizon
Almost all streetlights in West Africa were based on heavy lead acid batteries and were connected to the grid. This was problematic because lead acid batteries can be bulky and are always externally connected. This makes them vulnerable to theft, rusting and other flooding issues. Being connected to the grid was also unfortunate as they were constantly affected by power cuts, load shedding, grid failures etc. The streetlights were just not doing their job. People could not go out after a certain time every night and they could not carry out regular chores. They would have to wait until every the morning. This ideally should be a non-issue for anyone living in the 21st century.
Let There be Light
This time, Intelizon presented the perfect solution for the people of the region. Introducing the Zonstreet by Intelizon Energy. The Lithium Ion based battery pack was built into the lighting system eliminating the problem of theft completely. It is completely independent of the grid and immune to power cuts or grid failures of any sort. It is now possible to install the outdoor street lighting where they were previously not due to non-availability of the grid. The lighting solution stayed lit for about 10 to 12 hours every night and the run-time stayed relatively unaffected even during the wet season with extended periods of cloud cover. The revolutionary battery technology and efficient electronics in the system ensured that the power is highly optimized and the light never has to go off unceremoniously. Additionally, the Zonstreet requires minimal installation charges and almost no maintenance costs at all. It does not require the regular water topping and performs optimally even in high temperatures unlike the traditional lead acid based street lights.
Intelizon created the perfect technology to address all these issues faced by African communities in one product. Harnessing the unlimited source of solar energy to light up their streets at night was a revolution in the lives of the rural folk. They can now continue doing regular things even at night under the safety of the Zonstreet. Outdoor solar in lighting in Africa was largely unheard of when Intelizon entered the market and aided many communities and countless families.
Making it Happen on Ground
Mr. Ram Mohan, MD of Comafrique, took the onus of installing Zonstreet lights in Africa. “In the villages, the residents found the lights so good that, they were fighting over them and that they be installed near their homes”, he said. This is when he realized that the “Zonstreet works”. Apart from villages, another 10 lights were installed in the car parking area of Managament Development Institute in Gambia. Soon, Zonstreet became a an ideal option for other establishments and purposes such as warehouse lighting, work station lighting, private lighting etc. where working at night is routine and power-cuts were frequent.
Zonstreet is now being traded to other countries of Africa from Gambia setting the tone for Intelizon to establish itself as a well-known brand in Africa. read more →
Enter the Zonstreet Solar Powered Unwired Outdoor Lighting Solution
When Intelizon channel partner Atul Gondkar came to know about the intricacies faced by villages in Maharashtra, he contacted the Gram Panchayat who are a group of elders who head these villages. He explained to them that solar energy would be an excellent source of power and an absolute alternative to the grid based lighting. The design and technology that the Zonstreet entails are perfect for villages as the installation costs are low and maintenance costs are practically nil. It is a reliable source of clean energy and affordable energy for the village folk. The idea was perfectly in line with Intelizon’s mission of providing clean and affordable energy to communities who really need it. This simple idea along with the efficient electronics and pioneering technology of the Zon has the power to transform lives.
Why did the gram panchayats choose Zonstreet?
Our channel partner visited the Gram Panchayat with the Zon products to demonstrate just how they can help the community. He presented to them the luminaire with the in-built lithium ion battery and how the system is completely theft proof, unlike the lead acid battery based systems. The only operations the lighting needed was the on and off switch that anyone can do. All they needed to do was invest in the purchase of the lamps and practically nothing else. The luminaire powered by the highly optimized solar panel efficiently runs itself.
The Gram Panchayat was impressed by the first look of the products; so impressed, in fact, an initial order of 120 lamps made immediately. By the end of the year, Mr. Atul Gondkar was able to install up to 1500 lamps in villages across the state. So far, complaints related to the products or their maintenance has been extremely rare.
It Keeps Working
The communities have been satisfied with the on-field performance of Intelizon’s products. The Gram Panchayats have testified Zonstreet’s 5-year on-field operation with an official certificate. It is delightfully overwhelming for Intelizon to be awarded such an honor and an invaluable certification. Since the installation of the first solar lamp in 2011, the Sarpanchs are still in touch with Mr. Atul Gondkar and for their further demand of more lights every year. Even though Intelizon promised the communities minimum interaction for maintenance or any other issues, it wasn’t just a one-time transaction.
Every time they come back for more, the heads answer only three words on enquiring about the Zon’s performance. It keeps working!

The Consular General’s to India Visit
Mr. Ram Mohan, consular general of India for Gambia visited India in 2008 for an Indo-African summit at NRDC, New Delhi. A technology and research oriented company Intelizon Energy was also a part of the summit. At the end of the day summit, NRDC presented a souvenir to Mr. Ram Mohan while he was leaving. The souvenir was a Zontorch, a product of Intelizon Energy private limited. This marked a starting point for Intelizon’s safari to Africa.
The Power Cut That Initiated the ‘Light Up a Village’ Initiative
For about six months, Mr. Ram Mohan didn’t think of using the gift that he got in India. A long power cut compelled him to switch on the Zontorch. Gasp! He was amazed to see the torch to get switched on and work decently even after months of non-utilization.
Then he thought why not light up the villages of Gambia with Zonbulb, in a place where people spend each day 25 cents for a candle. 25 cents amount to 7.5$ a month and about 90$ a year, which is much higher than a Zonbulb which is 75$ and lasts about 5 to 6 years or more. So, he started a noble mission called “Light Up a Village Initiative”. He gathered sponsors and set up a village lighting committee for each village. Under this initiative, 3500 dollars were collected for each village from sponsors and lights worth it were distributed in each village of about 70 to 80 houses. The village lighting committee collected 5 cents each day or 1.5$ each month, which is then used for the maintenance of the lights. The amount which was collected from the villagers was apparently far less than what they usually spent on candles per year.
“Look at the happy faces! It is a bliss to watch them celebrate,” said Mr. Ram Mohan when he shared the pictures of “Light Up a Village Initiative”. The villagers said only one thing “Zon Works”. In few months, Zonbulb traveled to countries all over Africa.
Lighting That Eradicates Darkness in More Ways Than One
The new Zonbulb that became an essential part of many homes in the villages started to play a much larger role than previously envisaged. The unwired solar lighting did more than just replaced candles. The families that used to previously live in flickering candle light at night, depended on daylight for income generation. With the Zonbulb in their homes, they increased their productivity and enhanced their incomes. The children in the family also benefited from the new light and could study longer during late evenings. Their education is the main driving force behind their development. They are now able to leverage their new lighting to study better and eradicate poverty from their villages. This way, the Zonbulb drives development and growth of village families out of poverty.
This inspiring story of the Zonbulb is a testament to the kind of impact that efficient solar lighting can have not just in Africa but also across the world.
Due to lobbying, renewable energy has never been given a fair chance. There were a number of speculations about how renewable energy is not an option that is completely viable. However, times are changing and we as a society are forced to take a positive step to build a cleaner and greener planet as the fate of our planet lies on the brink of extinction. Intelizon lighting solutions has shown the world that it is not only highly possible to run industries on renewable energy, but also that the positive effects are undeniable.
Hindustan Zinc Ltd.
One of the world’s leading producers of lead, zinc, cadmium and silver is a mining company called Hindustan Zinc Ltd. Their branch in Yashad Bhawan, Udaipur is leading the way to a safer and cleaner environment-friendly world. After a good deal of research, the organization has come to the conclusion that renewable energy solutions are the best way forward. Being a company that takes their business ethics seriously, Hindustan Zinc Ltd. wanted to enhance all their operations such as smelting and mining by utilizing sustainable technologies.
Hindustan Zinc Ltd. installed 60 Intelizon Zonstreet solar lights on its premises. The lights are not attached to any grid or power source. Due to this, there is absolutely no non-renewable energy usage or wastage. Furthermore, the lights have been proven to be very safe to use since there is no risk of getting electrocuted. The only power source for the lights are solar panels that are placed at appropriate angles to face the sun.
Why Zonstreet Lights?
Intelizon turned out to be the solar lighting company of Hindustan Zinc Ltd.’s choice due to their proven reliability and the use of high-end technology.
- Instead of using the regular lead-acid batteries that do not last for a very long and consume an excessive amount of energy, Intelizon uses long-lasting lithium-ion batteries.
- The batteries are in-built, which also makes them tamper and theft-proof.
- Zonstreet lights use lenses and reflectors to increase the intensity of the lights though the wattage used is a lot lower than regular lights.
- Intelizon uses LED lights instead of regular incandescent lights. Due to this, the lights use approximately 90% less energy, making them an energy-efficient option.
- The lights are also a lot brighter than regular incandescent lights, which means that the same amount of electricity produces more intense light and lasts a lot longer.
- The lights are wireless so one does not necessarily have to manually turn them ON or OFF. This once again helps in the conservation of energy.
- The solar lights and panels are of very high-quality, so the cost of maintaining them are practically nil.
- LED lights fitted on Zonstreet lights last for an average of 5 years, making them the perfect lighting solution.
- Zonstreet lights have motion-sensors due to which they switch on every time a person walks past. This helps in the conservation of energy.
- Solar energy uses direct current instead of alternating current. The lack of power grids improves the amount of energy stored and further reduces the amount of energy wasted due to electricity conversion.
- The brightness of Intelizon Zonstreet lights auto-adjust to the intensity of ambient light, saving even more energy.
- Zonstreet GSM lights can be controlled with an IOS or an Android mobile phone.
- The lights are also aesthetically appealing.
