The International Solar Alliance (ISA), which aims to mobilize more than $1 trillion of solar power investment by 2030 in its member countries, expanded its scope of work by launching programs on solar panel and battery waste management and solar-powered hydrogen production in its fourth assembly held recently.

The levelized cost of solar electricity generation from a given rooftop area is the lowest in India (US$66/MWh) and China ($68/MWh), with the USA ($238/MWh) and UK ($251/MWh) representing some of the costliest countries, according to an international study based on data available as of 2018. The study also finds China (4.3 PWh/year), USA (4.2 PWh/year), and India (1.7 PWh/year) have the highest yearly potential of rooftop solar energy generation.

A robust distributed renewable energy ecosystem with a strong domestic industry will help provide good-quality, reliable electricity to rural households and enterprises and thus turbocharge green entrepreneurship—paving the way for a self-reliant India.

The EnerPack from Indian manufacturer Jakson consists of a hybrid inverter, lithium ferro phosphate batteries, and an intelligent energy management system that can smartly combine grid power, solar power, wind power, and even diesel generator power supply to maximize the use of renewable energy.

The annual rooftop solar installation in the twelve months ending June 30, 2021 included 1260 MW from the commercial and industrial sector and 488 MW from the residential segment.

A power system modeling study, jointly carried out by Lappeenranta-Lahti University of Technology (LUT) and Wärtsilä, explores the feasibility of a net-zero-emissions power system in India by 2050. It shows that an all-renewables power system, when paired with flexible generation technologies (thermal balancing power plants and energy storage), can improve the affordability of electricity while ensuring the reliability of system operations.

Multiple factors can affect the lifespan of a residential battery energy storage system. We examine the life of batteries in Part 3 of our series.

The second quarterly (April-May-June) addition of 521 MW is India’s highest-ever rooftop solar capacity installed in a quarter.

A report by BloombergNEF and Schneider Electric has pressed the case for governments to unlock the world’s potentially huge rooftop solar potential, and cited California’s solar mandate as a shining example.

Established in 2015, Gurugram-based solar EPC player Corrit Energy and Infra caters to a diverse customer profile ranging from large-scale industries to residences. Director and CEO Mayur Misra speaks about the current state of residential rooftop solar in India and emerging trends.
