Residential PV

NREL researchers model viable pathways to supplying the estimated 60 TW of capacity required for decarbonization, and study the effect that disruptive solar technologies may have on deployment cost and market opportunity.

In the first week of May, the photovoltaic systems installed in Germany made the largest contribution to net electricity generation. They fed a total of 1,744.46 GWh of solar power into the grid and thus had a share of 23.6%.

Developed by Chinese researchers, the system is designed to reach a heating capacity of 5.7 kW and an overall coefficient of performance of 1.40 at nominal conditions. It is made with an engine unit, a heat pump unit, and a gas resonator unit in a loop.

Japanese policymakers are now looking at rooftop solar panels as land is scarce in the country and agrivoltaics, building-integrated PV (BIPV), and floating solar are still in their infancy, reports Mark Hutchins.

The UAE is expected to generate 25% of its electricity from solar energy and have a total installed solar capacity of 44 GW by 2050. The Middle East Solar Industry Association (MESIA) describes the challenges the country has to address to make this target achievable.

In a new weekly update for pv magazine, Solcast, a DNV company, presents the solar irradiance data it collected for Europe in April. These data show that Spain benefitted from solar irradiance 20% to 30% above average during the last month, while in the rest of Europe irradiance was below average.

Researchers have defined a new machine learning-based methodology that reportedly reduces customer acquisition costs by about 15% or $0.07/Watt. It is based on an adapted version of the XGBoost algorithm and considers factors such as summer bills, household income, and homeowner’s age, among others.

Three leading environmental groups have filed a petition to the California Court of Appeals to review the state’s solar net energy metering cuts.

China’s DAH Solar has added a specially designed microinverter to its Full-screen module, making the ‘SolarUnit’ a formidable offering for the rooftop PV segment. DAH Solar President Shenheng Xie took pv magazine through some of the system’s key features and the advantages they promise once installed.

The International Energy Agency expects Australia’s “outstanding” economic fundamentals for residential and commercial rooftop solar will see the sector stabilize in 2023 after a new report revealed the PV market contracted in 2022, when the country added 4 GW of installed solar power.
