Residential PV

The 97%-efficient device is said to be the most powerful PV microinverter developed by the company to date and is capable of forming a microgrid during a power outage. The U.S. manufacturer expects to ship the first products in December.

South Korean battery manufacturer LG Energy Solution has launched a new inverter in the Australian market, adding a 5 kW hybrid inverter to its Residential Energy Storage Unit (RESU) Home battery energy storage range.

India needs to install an average of 25 GW solar capacity every year to reach its renewable energy target of ‘450 GW by 2030’ with over 60% (280 GW) from solar. The nation must build enough manufacturing capacity back home to be ready on the supply side to support the new installations. 

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.
