Frequently Asked Questions
By providing detailed equipment breakdowns, clear specifications, and transparent pricing, our quotations help you choose the best installer for your home solar system.
Our quotations provide a detailed breakdown of all essential solar equipment, such as solar panels, inverters, batteries, ACDB boxes, DCDB boxes, mounting structures, AC/DC cables, conduit pipes, etc.
No, our quotations clearly outline all charges related to the installation process, ensuring you have a comprehensive understanding of the overall expenses involved.
Yes, our quotations are completely free. We provide you with detailed information on solar equipment and installation costs from multiple installers near you, at no charge.
We partner with DISCOM-empanelled solar installation companies throughout India. While selecting them, we carefully check their portfolio and align them with our objectives and guidelines so that you as a customer get the best installation services.
A solar installer can visit your site to assess your roof's suitability based on its orientation, angle, shading and structural integrity.
For a solar subsidy, you must install an on-grid solar system. Further, you have to choose vendors empanelled with local DISCOMs and using ALMM-listed DCR solar modules, you become eligible for government subsidies.
If your system is connected to the grid without a battery backup, your solar panels will not provide power during a grid outage for safety reasons. Off-grid and hybrid solar systems can continue to supply power during outages, however, there is no subsidy for these systems.
Yes, electric cars can be charged with solar power systems. For this, you will just have to connect your solar car charging adapter with your electric panel and car.
While HJT is the latest technology in the solar sector, it is not yet available in the Indian market. People, at present, mostly use TOPCon solar panels for solar systems.
It takes less than 45 days to install a small solar panel system. Within this time frame, you can expect completion of net metering as well.
In India, you need to obtain permission from your local DISCOM (electricity distribution company) to install an on-grid solar system for your home. We can assist you in acquiring the required permits for your solar panel installation.
A 1 kW solar system costs between Rs. 90,000 and Rs. 1,30,000 in India. However, various factors such as the type & brand of panel, inverters, and other accessories influence the price of these panels.
A solar panel system generates electricity by converting sunlight into electrical energy. First, the photovoltaic (PV) cells in the solar panels absorb sunlight and convert it into direct current (DC) electricity. Then, the solar inverter changes the DC electricity into alternating current (AC).
A solar photovoltaic system consists of several key components - a solar PV array, a solar inverter, an ACDB and DCDB box, an array junction box, a net metre, a mounting structure and a lighting arrester.
The lifespan of a standard solar panel is 25 to 30 years. However, this does not imply that a solar panel will stop generating electricity after 25 years rather it can produce at 80% of its original capacity.
In India, 2 major types of solar panels are mostly purchased - Mono-PERC half-cut and TOPCon. Both these panels are available in India with half-cut and monofacial/bifacial features.
Going solar is a smart choice because it 1) reduces electricity bills [ a 3 kW system can reduce the bill by up to Rs. 34,500 annually] 2) offers up to Rs. 78,000 in government subsidies, 3) provides a 20-30% return on investment, 4) requires 1%-2% of initial setup cost in maintenance and 5) reduces carbon emissions.
No, Solar Projects cannot damage your roof when properly installed by a professional. The structure on which the solar panels are placed relies on civil work done on the roof.
In India, you can find various types of solar batteries, including lead-acid, nickel-cadmium, flow batteries and lithium-ion. Lead-acid batteries are the oldest among them, while lithium-ion and flow batteries are the newest additions to the market.
For residential purposes, lithium-ion batteries are the ideal choice. They can store a higher amount of power in a limited space. It lets you maximise the energy utilisation.
The number of solar panels depends on the solar capacity required to power your house and the Wp reading of the panel. For example, if you require up to 15 units of electricity per day, you can install a 3 kW solar system, for which you will need 6 solar Mono-PERC solar panels having a capacity of 540 Wp.
Location, plant layout, shading and roof orientation, design of the system, equipment quality, operations and maintenance are the factors that can affect solar electricity generation.
In most states, net metering credits do not expire and can roll over from one month to another. However, you need to use the rolled-over electricity unit within the span of a year.
Contrary to popular belief solar panels typically reach peak production when the temperature is around 27 degrees Celsius and most efficiently between 10 am and 2 pm, when the sun is at its highest point in the sky.
Solar energy comes free of cost. You just need to install a solar system at your house to enjoy this free electricity. Installing a 3 kW rooftop solar system can generate approximately 360 units of electricity per month, saving around Rs. 34,500 annually on electricity bills at Rs. 8 each month.
At present bifacial TOPCon panels are the most efficient solar panels available in India. When you install the solar system with us, our installer will properly guide you about the solar panels you should ideally buy.
Solar energy is suitable for many places, as long as sufficient sunlight is available and it falls on the panel perpendicular. You can install a solar system even in places which are cloudy throughout the year or remote or snowy areas.
No, solar panels do not generate noise. This is because they do not have moving parts that would create any sound, making them silent during operation.
It is recommended that you hire a professional solar system installation. They will ensure the setup of your solar panel system, including the mounting structure quality and panel orientation are proper.
Even a small area of shade on a solar panel can totally disrupt its energy production. Therefore, you need to avoid shade falling on the solar panel.
Investing in solar panel systems offers a compelling return on investment (ROI) of 25-30%, making it a secure and attractive financial choice. Rooftop solar has become a smart and low-risk investment opportunity because of a relatively short payback period of 3-5 years.
In gross metering, you buy the entire energy you consume at the retail tariff, which is higher than the feed-in tariff (FIT) or the tariff on your solar electricity export. On the other hand, in net metering, your electricity bill is reduced by the amount of power you export to the grid, resulting in a proportional decrease in your overall bill.
Before buying solar products in India, you should ideally look for the BIS (Bureau of Indian Standards) and ALMM (Approved List of Models & Manufacturers) certifications. This certification ensures that the products meet the specified quality, safety, and performance standards set by the Indian government.
Rooftop solar has grown 10-fold from 1.8 GW in 2019 to 12 GW in 2024. The future of solar energy looks promising as India looks to achieve its 500 GW renewable energy target by 2030.
