Residential PV

Xavier Daval, the president of Syndicat des énergies renouvelables (SER), the French renewables association – spoke with pv magazine at Intersolar 2023 about solar and nuclear power in France, as well as the prospects for PV prices and installations. He touched on the market for power purchase agreements (PPA) and the outlook for solar manufacturing in France, where PV installations could hit 3 GW this year.

In May alone, the nation’s new PV additions hit 1,040 MW. Its cumulative PV capacity reached 72.5 GW.

Clean Energy Associates (CEA) has performed a safety audit on more than 600 rooftop PV systems and has found that 97% of installations have major safety concerns. It says that 49% of sites have grounding issues, 47% have damaged modules, and 41% have cross-mated connectors.

Solar’s levelized cost of electricity will reach $30/MWh in 2050, as global capacity surges, said DNV.

According to EUPD Research figures, PV system prices for single-family homes in Germany rose slightly in the second quarter of 2023. Despite falling module prices, analysts do not expect costs to fall significantly in the coming months. Prices also depend heavily on installation context, component selection, and region, which is why price comparisons with average figures, such as those used by Enpal in emails to private households, are not particularly meaningful.

US-based Lunar Energy offers batteries, hybrid inverters, and shutdown devices.

K2, a mounting system supplier, showcased a range of new solutions at Intersolar Europe, including a new mounting structure for green rooftops. It allows for portrait and landscape module elevation at 10 degrees and 15 degrees, with maximum module sizes of 2,400 mm x 1,350 mm.

Key Energy has installed a three-phase flywheel energy storage system at a residence east of Perth, Western Australia. The 8 kW/32 kWh system was installed over two days in an above-ground enclosure, dramatically cutting the time needed to install the flywheel system.

A new report by HelioVolta shows that 62% of inspected PV projects have critical or major issues.

The National Energy Administration (NEA) says China installed 61.21 GW of solar in the first five months of this year, bringing the nation to nearly 453 GW of cumulative installed PV capacity by the end of May.
