Scientists at the Polish Academy of Sciences have studied PV installations older than 15 years and observed a decrease in energy productivity ranging from 1.9% to 2.9% over a 16-year period. They conducted their tests on two rooftop PV systems in Sinsheim, a town in southwestern Germany. The first system, a 37.8 kW grid-connected array, consists of …

Despite the pressure the pandemic has placed on supply chains and income levels, the number of people who source electricity from solar energy kits has continued to grow and has now reached 490 million. According to the “Off-Grid Solar Market Trends Report 2022: State of The Sector” report – published by the World Bank’s Lighting Global, International …
Scientists at the National Technical University of Athens have used a machine-learning method known as transfer- learning (TL) to develop a new solar power forecast modeling intended at helping developers with limited data size. The TL method uses a trained model on one task to repurpose in a second, related task. The researchers used three …

The number of off-grid properties in Australia is growing rapidly, albeit from a low baseline. The number of off-grid properties for sale in 2020 was just 809. By 2022, there was 1362 – close to a 70% increase. By comparison, the number of solar houses on the market increased by just 26% in that same period. Commodore …

Researchers in Hungary have found that a high tilt angle may increase power forecast errors in a PV installation by up to 49%. They also ascertained that undersizing the inverters by a sizing factor of 1.5 may reduce forecast errors by up to 25%.

Solar cell and module prices have increased by more than 40% over the last 18 months in India, driven by polysilicon prices. However, bid tariffs have remained lower than what is needed to mitigate the rise in PV module prices. The risk of lower returns is significant for 4.4 GW of projects that have been …

Poland allocates 870 GW of solar in renewables auctions, lowest bid for PV was $0.05078/kWh The Polish energy regulator has allocated 570 GW of PV capacity in a procurement exercise for projects exceeding 1 MW in size and around 300 MW in an auction for projects with capacities of up to 1 MW. The Polish …
UK government opens consultation on large scale PV-plus-storage rules In the U.K., systems bigger than 50 MW fall under the Nationally Significant Infrastructure Projects regime and require special permitting. With the aim of optimizing the market for higher storage penetration, the Department for Business, Energy and Industrial Strategy is holding a consultation until March 25 …
