Here are the services we offer

  • 1. How much area does a photovoltaic system require?

    A typical 1 kilowatt photovoltaic system would require about 10 square meters (i.e. 80 square feet) of open space. Larger photovoltaic systems can also require less space depends on dimensions of the roof.

  • 2. How much energy does a photovoltaic system generate?

    A typical 1 kilowatt photovoltaic system depends on solar insolation in that area. Usually, it would generate an average of 4-5 units (i.e. kilowatt-hours, kWh) per day.

  • 3. Should I have a battery?

    It depends on the consumption cycle. If the consumption cycle matched the generation cycle then battery may not be required. Also, in case of net metering, excess power will be credited in the bill so no battery is required.

  • 4. I have roof with shadow of another higher building is that suitable for roof top solar power plant?

    No, shade free area is must as that will effect generation of solar power

  • 5. What happens to power generated by roof top solar system?

    Rooftop solar power generated is feed in to main incomer so will be used as priority till available.

  • 6. I have Diesel Generator set supply also with Electric Board supply; can I install roof top system also as 3rd power source for self use?

    Yes

  • 7. Is there any limit to install max capacity of solar roof top system w.r.t my consumption/Load?

    In general, 100% of sanctioned loan can be the max installed possible capacity of solar roof top system.

  • 8. Can I sell power generated from my roof top solar power plant?

    As of Sept.2015, only one of the state roof top policies (Uttrakhand) allowed while for rest of the states, roof top is for self consumption/captive consumption only.

  • 9. What is Net metering & In which states it is currently active?

    For detailed and easy explanation, check out our page - Lets simplify solar and illustrative diagram Broadly all states are adopting net metering policy. The same can be confirmed with Shriyam Solar Energy team at the time of execution.

  • 10. What is life of solar roof top system?

    Solar panels manufacturers warranty is 25years. So, broadly life of solar roof top is 25 years. However, it does function after 25 years with 80% output.

  • 11. Is there any warranty for solar panels used in solar roof top system?

    Yes, solar panels comes with the warranty of 25 years

  • 12. Who will take care of maintenance of roof top solar power plant after installation?

    O&M activity for rooftop is an optional service from Shriyam Solar Energy Solar for which yearly fees will be charged. The second option could be from your end. It is advisable to provide O&M service to Shriyam Solar Energy Solar as they will know we have dedicated experienced team who knows intricacies involved.

  • 13. What is payback period of solar -roof top system?

    4-6 years depends on the tariff

  • 14. How much solar power systems reliable and consistent?

    Solar electric systems can be more reliable than the utility company. They have no moving parts and off-grid systems are not subject to power outages.

  • 15. What will happen during winters or low daylight time, will my output drop?

    Solar panels work just fine in ambient light and will produce significant energy in the fog or on overcast days. In bad weather, the production may not be 100% but they will produce power. On cloudy days, they may produce 60% of the required output. Germany, who ranks low in sunny days, is the solar energy capital of the world.

  • 16. Is the installation cost for solar power very high?

    It is a myth that going solar can be a costly affair. In fact, solar is a very wise choice for people who could actually use the extra couple hundred bucks a month that they are currently paying in power bills. With net metering, the payback period is even less

  • 17. What will happen to the extra energy I may not consume?

    Your system generates power during the day and excess is fed back into the grid through a system called net metering. When this happens, your meter records extra energy and your utility company credits you for that power in case of net metering.

  • 18. What kind of maintenance is required in solar?

    They rarely require any maintenance or cleaning, plus they have warranty of minimum 25 years. All it requires is to wash panels once every 15-20 days with a cloth.

  • 19. Will my roof leak, deteriorate or collapse due to installing of solar panels?

    Nothing will happen

  • 20. How long it takes to install a solar system?

    A typical solar panel installation takes about 45- 60 days depending on the availability of the manufacturing lot.

  • 21. Do my solar panels need to have tracking mechanism to follow sun?

    Solar tracker increases efficiency but comes with an additional cost. However, the increased efficiency and the cost implications depends on project to project basis.
