Commercial & Industrial PV

A recently published report from the IEA-PVPS on building integrated photovoltaics (BIPV) digitalization found many BIPV professionals are unsure of a suitable method for estimating shading in BIPV projects.

Germany’s latest solar auction allocated 104 MW of solar for buildings and noise barriers on motorways. The tender volume was 202 MW which went partly unsubscribed. The volume-weighted average award value fell slightly to €0.0874 ($0.093)/kWh.

In another record year for solar, SolarPower Europe estimates PV in Europe grew by 47% in 2022, rising from 28.1 GW in 2021 to 41.4 GW this year. Germany installed the most with 7.9 GW, followed by Spain at 7.5 GW, and Poland at 4.9 GW. For the first time, the top 10 European solar markets all added at least 1 GW.

Slovenia’s cumulative PV capacity additions could grow from 466 MW in 2021 to 724 MW by the end of this year. The residential market will account for almost all new capacity, and demand is expected to grow under a net-metering scheme extension until the end of 2023.

Brazil’s newly elected government, under Luiz Inácio “Lula” da Silva, will face energy-transition and decentralization issues during critically important years in the fight to curb climate change. Livia Neves reports from Rio de Janeiro.

The Tokyo Metropolitan Assembly has approved new provisions to make solar installations mandatory for new homes. The rules apply to homes with total rooftop areas of more than 20 square meters, and to buildings with rooftops smaller than 2,000 square meters.

New life-cycle assessment (LCA) data for PV systems confirms that greenhouse gas emissions from 1 kWh of solar electricity are far lower than emissions from fossil-fuel power plants. The difference has been fairly constant since 2018, but has improved substantially since when IEA PVPS started reporting on this measure in 1996.

PV module prices have finally stabilized and a slight downward trend has even started to set in. Whether this will continue depends mainly on how demand shapes up over the next few months. The softening of prices reflects a gradual build-up of inventories which need to be drawn down again this year, if possible – even if it means slashing prices. But for other PV-system components, the situation is quite different, writes Martin Schachinger of solar wholesaler pvXchange.

South African researchers have developed a new cleaning system for solar panels that uses a color-sensing light-to-frequency converter to detect dirt. It can reportedly remove around 95% of the dust from a PV panel in less than a minute, at a lower cost than other systems.

Meteo for Energy offers meteorological prediction and energy production models for photovoltaic, solar thermal, and wind power generation. The new model applies “deep learning” to images from the Meteosat satellite.
