• India is endowed with over 300days of sunny days in a year • About 5,000 trillion kWh per year energy is incident over India’s land area

• Most parts receiving 4-7 kWh per Sq. m per day • As of 31 January 2018 the country's solar power had 20 GW total capacity • The solar energy available in a single year exceeds the possible energy output of all of the fossil fuel energy reserves in India

Commercially viable technologies

Mono Crystalline

– Made from a large crystal of silicon

– Most efficient panels

– Effective utilization of space

– Less Heat

– Performs better in low light conditions

Poly Crystalline

Thin film

– Shattered glass look

– Commonly used in India

– Reflective appearance

– Made from cast square ingots

– Made by deposit of thin layers, or thin film of PV material on a substrate

– Variants – CdTe – Cadmium Telluride; CIGS – Copper Indium Galium Selenide; a-Si – Amorphous Silicon

– Cheaper, but less efficient than a-Si – Crystalline Silicon.

Requirement - 1,000 square metres shade free area - Total Project cost - Rs 47 to 55 lakhs

Project Economics

Solar Power is currently popular due to the following benefits: Cost competitive with thermal power Does not depend on availability and price fluctuation of fossil fuels A source of clean power

Typical 100 kW Solar

Benefits -1.5 lakh units/year electricity generation - Break even at 3-6 years with AD - Free power till 25 years after Break even period - 150 tonnes/year carbon reduction

13

– Compelling economics

Cost of power through solar – Rs 4 /unit for a 25 year period

Cost of power through grid – Rs 6 to 10 per unit (varies)

– Sustainability

Lower organizational carbon footprint

Green Building certification for commercial buildings

What does it mean for you in India?

14

Solar + Diesel – Even better economics

Reduce diesel consumption by 50% The cost power – Rs. 4 Vs. Rs. 18 As the usage of the diesel genset increases the pay back becomes even more attractive
