Residential PV

Multiple factors affect the productive lifespans of residential solar inverters. In the second part of our new series on resiliency, we look at PV inverters.

The current proposed draft policy has the potential to act as a game-changer for the renewable energy industry. However, the government needs to relook at certain elements.

The new residential module of the U.S.-based manufacturer has a power conversion efficiency of 20.40%, a size of 1,076×1,957x35mm, and a weight of 21.3kg. The product is claimed to be compatible with next-generation, module-level power electronics.

The mounting structure relies on a 5.8m long support rail that does not lie on the roof but is connected directly to a purlin placed below with self-drilling support screws.

Dutch startup Solarge has developed a 500 W panel that weighs 50% less than conventional glass-backsheet modules. The new product can be fixed to rooftops with roofing anchors, which eliminates the need for ballast, according to the manufacturer.

The system is claimed to be India’s largest residential on-grid residential solar installation using 540 Wp PV modules. It uses 68 numbers of JA Solar 540 Wp half-cell mono PERC modules and 27kW Fronius inverter.

India’s solar capacity growth up to 2030 also means the generation of a significant mass of PV module waste due to early failures or damages during transportation, installation, and operation. The waste generation could be 21 kilotonnes assuming India’s cumulative installed PV capacity grows to 287.4 GW by 2030 from 40 GW in 2020. This doesn’t include end-of-life panel waste as PV systems installed between 2020-30 are assumed to have at least 30 years of lifetime.

Switzerland-based Energy Pier has developed a new concept for hybrid-wind solar projects located along highways. The proposed solution combines a rooftop PV system with small scale wind generators that are installed on both sides of the supporting pillars of the system.

India will require large swaths of land for the huge expansion of renewable energy capacity over the coming decades. The energy transition requires planning for proper siting of these plants and solutions like agrivoltaics, distributed energy systems, and offshore wind to reduce land-use conflicts.

UK’s development finance institution CDC will invest $1 billion in green projects in India between 2022-26. Besides, UK has committed a new $200-million private and multilateral investment into the joint UK-India Green Growth Equity Fund that invests in Indian renewable energy.
