Residential PV

Trina Solar says its new TOPCon solar panel combines a double-glass design with n-type technology. Its efficiency ranges from 20.8% to 22.3% and the power output is between 415 W and 445 W.

Scientists in Belgium have designed a solar-powered electrolyzer that uses standard-sized, large area shingled silicon PV for water splitting. The system is reportedly able to achieve solar-to-hydrogen efficiency of 10% at electrolyzer current densities of approximately 60 mA cm−2.

The United Kingdom hit 14.3 GW of cumulative solar capacity by the end of last year, according to provisional government data. New solar capacity grew by 4% year on year, with the rooftop PV market accounting for most of the new installations.

Gautam Solar’s 10-busbar solar panels feature peak power outputs ranging from 520 W to 550 W, with front-side conversion efficiencies ranging from 20.11% to 21.27%.

With 25 GW of solar now under development, on top of 107 GW of existing capacity on the US grid, the energy transition is in full swing.

Tongwei is offering six versions of its monofacial monocrystalline panels, with power outputs ranging from 400 W to 430 W and power conversion efficiencies between 20.1% and 21.7%.

An international research group has developed a new Aalborg inverter design for high-power applications in solar arrays. The device has fewer switches than conventional, voltage-source inverters and can reportedly improve PV system performance by reducing switching losses.

Component cost declines, local manufacturing and distributed energy are the three big trends for the renewable energy sector this year, according to S&P Global.

The Dutch heat pump market grew by 57% in 2022, with 70,000 heat pumps installed in new buildings and 40,000 in existing homes. The Dutch Heat Pump Association (DHPA) now wants to focus on investing in solar-thermal heat pumps and bringing the technology to low-income households.

Japan’s National Institute of Technology and Evaluation (NITE) says in a new report that snow has damaged 43 PV installations of different sizes over the past four years. It urges PV system owners to conduct regular site inspections, use surveillance cameras, and remove snow at early stages.
