rooftop solar

A British-Chinese research group has created a new framework to assess the performance and efficiency limits of photovoltaic-thermal solar panels. They say that the improvement of spectral-splitting (SS) filters in the devices will be the key to their future commercial success.

India’s Ministry of New and Renewable Energy is funding research to develop high-efficiency crystalline silicon solar cells, as well as perovskites.

Researchers at the Michigan Technological University claim to have demonstrated that PV system owners in the United Stated are unjustly subsidizing electric utilities. Their analysis showed that, thanks to rooftop PV, utilities and their non-PV customers can save money from avoided costs for new grid, reserve, and generation capacity, as well as for avoided operation and maintenance and environmental and health liabilities due to fossil fuel power generation.

After a Covid-19-stunted Q2, the company reported improved revenues for a second straight quarter, and closed 2020 with revenues north of $770 million.

According to a recent report from Brazilian consultancy Greener, the country imported 4.76 GW last year. Domestic PV module makers had a 3.8% market share with around 190 MW in shipped modules. The analyst also revealed that prices for distributed generation PV systems rose by 20% in 2020.

Zhonghuan and Longi raised the prices of their wafers before the Chinese New Year holiday. Longi also secured more polysilicon and glass through two different orders, with OCI Group and Flat Glass, respectively.

Under typical indoor illumination of around 500 lux, from light sources such as LED or fluorescent light, the device’s power conversion efficiency is just below 15%. The largest device has an open-circuit voltage of 3.8 V, a short-circuit current of 146 μA, and an output power of 418 μW. The product can also be used in conjunction with capacitors to replace batteries or to prolong their lifetime in low-power applications.

French renewables specialist Enercoop has secured an annual solar power supply of 25 GWh over a 30-year period through three new deals.

Sweden saw extraordinary high spot prices during last summer, due to difficult power transmission from the north, where most of power generators are located, to the south of the country, where most of the demand is concentrated. According to Swedish PV association Svensk Solenergy, solar-plus-storage offers a quick and scalable solution to avoid expensive and slow grid improvements.

Around 2,400 South Australians will soon be fogging up the bathroom mirror without qualms about the cost of heating water, as Solahart is set to implement a new trial to control hot water systems.
