We got our Solar Plant installed by this firm more than a year ago at Varanasi. Recently we observed some problems in the structure as it got loosened over the year. After the complaint, the problem got rectified in two days. The team had come from Lucknow. After sales service so far seems good and responsible. Sabhajeet Singh

What is a solar rooftop system?
A solar rooftop system is a combination of many components that convert sunlight into usable electricity.
The components of a rooftop solar include the following:- Solar panels
- Solar inverter
- Solar panel galvanized from mounting structures with square foundation
- (AC and DC cables) & Earthing Cable
- AC combiner box (ACDB)
- DC combiner box (DCDB)
- MC4 connectors
- Earthing with chemical bag & Lightning arrestor
- Battery if applicable
-
How does a solar rooftop system work?
- A solar rooftop system works on the concept of conversion of sunlight into electricity. The phenomenon is known as the photovoltaic effect.
- When sunlight falls on the PV cells in a solar panel, the sunlight is converted into electricity. The generated power is DC current. Solar Inverter is used to convert that DC power into usable AC power.
- The generated AC electricity is fed into a bidirectional meter that supplies power to the house. It also exports excess power to the DISCOM (grid) and imports power from the grid if electricity generated by the rooftop solar system is not enough to cover the daily requirement.

If you want to save money from the sun, Solar is the best investment for you. Solar allows you to reduce on your monthly electric bills plus it also allows you to save the planet by going green. Solar energy is a true form of renewable clean energy which leads to zero pollution (air, noise, land) and emits no greenhouse gases mitigating climate change.
-
Is solar power safe?
Yes. The electricity produced by a solar power system is no different than the electricity you get from your electricity distribution company. The only difference is the source. Moreover, it is among the safest source of electricity consumption because it is neither hazardous nor does it release any toxic or harmful gases during production.
