India Rooftop Solar Advisor Report

The India Rooftop Solar Advisor is a Complete Guide to Putting Up a Rooftop Solar Power Plant on Commercial and Industrial Establishments in India

 

Rooftop Solar

Rooftop solar power is being increasingly embraced by commercial, industrial, and residential consumers as a significant contributor to their energy mix because it combines

  • On-site generation of power
  • Utilizing unused rooftop space
  • Reasonable cost

Generating power on-site frees the consumer from being at the mercy of grid failures and even load shedding as the solar plant is not dependent on grid infrastructure to deliver its power to the load. In this sense a solar plant is similar to a diesel generator, but without the associated noise and emissions.

Rooftop space is often left unutilised in many establishments; installing a solar plant on the roof is a great way to derive additional value from your building.

Solar power may be cheaper than even grid power for some consumers; it is much cheaper than diesel power for all consumers, and offers the added advantage of fixing the cost of power for the next 25 years.

In addition, solar plants have no moving parts and are therefore very reliable, requiring minimal maintenance expenditure or downtime.
