Residential PV

Australian solar window supplier ClearVue says its products can reduce carbon emissions in buildings by as much as 90%, while California-based BIPV window coating producer Ubiquitous Energy has raised $70 million to scale up its own tech.

The Indian government has ruled that only solar products and companies on the Approved List of Models and Manufacturers will be eligible for open-access and net-metering projects, in addition to government-backed installations. This includes arrays set up to sell electricity to the government under Section 63 of the Electricity Act, 2003. The amendment will apply to projects that request open access or net metering from April 1, 2022.

Toshiba has developed a battery that can be used with PV modules, with a design that charges and discharges at high currents. The new 20Ah-HP SCiB product has a rated capacity of 20Ah, a nominal voltage of 2.3V, and an input power of 1,900W. It measures 116 mm x 22 mm x 106 mm and weighs 545 grams.

The device has a 4-in-1 design, which means it can be connected with four solar panels with a power output of up to 625 W each, through four independent connections. The output of each panel is tracked and converted individually. According to the Chinese manufacturer, the micro-inverter can ensure savings of up to 50% due to the lower number of devices and cables needed.

The research institute has upgraded its REopt web tool to include ground-source heat pump technologies. US homeowners will now be able to simulate the impact of converting conventional heating and cooling systems to geothermal heat pumps.

Of this new capacity, 8.9 GW may come from distributed generation and 3.2 GW from utility scale solar. By the end of December 2022, the country’s installed solar power should reach 25 GW, according to new figures from Brazilian trade body ABSolar.

Cornell Researchers have found that upstate New Yorkers prefer rooftop solar to community solar under 50 acres, but opinions are split 50/50 over large-scale ground mounts. The distaste for utility-scale solar is strongest when converting forests, public land and productive farmland.

Spanish researchers have developed a new modeling technique to assess the performance of semi-transparent PV systems for greenhouses. Their novel approach considers the broadband and spectral content of the irradiance, the solar cell technology and its performance metrics, and the relationship between the photosynthetic rate and the effective photon flux that falls on the crops.

The new package includes an increase in solar capacity, to be allocated through tenders, and the mandatory installation of PV systems in all commercial buildings.

About 46% of all new generating capacity in the United States is expected to be PV this year, giving it the largest share of the new US generation mix.
