Solar Energy

Yes. There are multiple schemes and incentives from the Central and State governments. A recent example is the PM Surya Ghar: Muft Bijli Yojana (PMSG) to encourage rooftop solar for residential households, including free electricity units under some variants. Additionally, MNRE (Ministry of New & Renewable Energy) periodically offers subsidies, grants, and soft financing for solar installations and battery storage.

As of late 2024 / early 2025, India has over 200 GW of installed renewable energy capacity, accounting for ~46-50% of its total electricity capacity. The government is targeting 500 GW of non-fossil (renewable + nuclear + large hydro) energy capacity by 2030.

Solar Energy is extremely cost-effective as compared to conventional sources of power and other green power sources.

Many developers talk about total generation (kWh), but that doesn’t reflect how well the system is performing.

Performance Ratio (PR) measures how efficiently a solar system converts sunlight into electricity, adjusted for location and radiation.

A healthy industrial solar PR should range from 78–85%.

Low PR indicates losses from inverter efficiency, dust, shading, wiring, or module mismatch.

Enerco’s performance audits and SCADA analytics identify hidden losses that can recover 2–5% of annual generation — translating to lakhs in annual savings.

Solar Energy is definitely better than Thermal power in terms of green energy quotient. There is no fuel buring and hence no SOx NOx emissions. Moreover Solar PV (Photo Voltaic) requires no water for operations and negligible water for maintenance.

Thanks to the falling costs, Solar Energy (Power) is becoming increasingly viable. With increased awareness about Climate change Solar PV adoption will accelerate at rapid pace in the near future.

Solar Energy is indeed green and clean.

The green quotient of a technology is determined by the ENERGY PAYBACK of the technology. This is the time taken by the technology to generate equivalent amount of power in terms of energy-equivalent that was used in production of the technology itself. The energy payback for Solar PV is 2-3 years (shortest in entire renewable technologies) depending on various factors. This means that Solar PV generates 10x or 10 times the power that was used in manufacturing and installing it. Hence it is truly green.

And yes it is clean too - it generates no SOx NOx or any other gases while producing power.

The payback period typically depends on several variables: the size of your system (kW), consumption (units), electricity tariff in your region, availability of subsidies, and whether it's grid-tied or off-grid. Roughly, many residential rooftop solar systems see payback in 3-4 years under favorable conditions.

Commercial and industrial setups may take 2-3 years or a bit more when costs are higher but savings and incentives are larger.

Savings come from reducing electricity bills + sometimes earning by feeding excess power back into the grid (net metering).

Floating Solar Plants are solar power installations that float on water bodies like lakes, ponds, and reservoirs. They are an innovative way to generate solar energy without using valuable land space.

Solar power is the use of Solar energy to generate electrical power or electricity. The 2 ways to generate Solar Power is by using either Solar Thermal energy or by the use of Solar Light (Photo) energy.

Solar Photo Voltaic (PV) is more popular due to it's simplicity, scalability and straight-forward conversion. Moreover Solar PV can be installed close to human habitat for smaller capacities starting from as small as few Watts on rooftops to multi-MW sized Solar Parks.
