The manufacturer said the 40/40 warranty is the longest and most comprehensive combined warranty offered in the photovoltaic industry to date. The product line is sold in most countries outside the United States and Canada under the SunPower Maxeon brand.

Canadian companies Invinity and Elemental Energy are planning to couple a 21 MW solar plant under development in Alberta with 8.4 MWh of vanadium redox flow battery storage capacity.

Developed by French start-up Ecosun, the trailer is equipped with 15 solar panels with output of 360 W and batteries with a storage capacity of 23 kWh. It can be used for construction sites, military camps and water pumping systems.

The Lithuanian government has decided to increase the 2022 budget for the solar rebates by €35 million after the initial phases of the program showed strong success among homeowners.

Churches use energy mostly during the day, which makes them ideal buildings to deploy solar panels. Scientists in the United Kingdom have assessed the financial viability of a rooftop PV project for Bath Abbey and found that it could become profitable after 13 years.

Chinese scientists used perovskitoids as 1D and 0D capping layer materials for the cell’s perovskite layer. These materials enabled an effective and all-around passivation of the perovskite surfaces and grain boundaries, which prevents undesired Shockley-Read-Hall recombination and material degradation. The device achieved a power conversion efficiency of 24.18%, an open-circuit voltage of 1.151 V, a short-circuit current of 25.96 mA/cm2, and fill factor of 80.91%. 

Researchers in Thailand have developed an anti-reflective and anti-soiling coating for commercial solar modules that is claimed to increase power yield by over 6%. The coating has photocatalytic properties that make the organic compounds adsorbed on the solar module surface decompose, thus preparing them to be easily washed off by rainwater.

Norway’s clean energy agency Enova will increase the maximum PV system size eligible for rebates from 15 to 20 kW and the maximum subsidy amount from 1,250 to 2,000 NOK ($226.7) per kW installed. In addition, new subsidies of up to 10,000 NOK will be introduced for energy management systems that are often installed alongside solar arrays.

Created by scientists in Korea, the shape-transformable 3D PV system is claimed to be able to increase electricity yield by 60% over a day compared to a fixed flat panel due to the shorter shadow length and the bifacial effect obtained during shape transformation. The proposed system doesn’t need any machinery to follow the sun and its developers said it would be a perfect solution for both urban and rural environments with limited space.

The country’s cumulative PV capacity reached 1.77 GW at the end of December.
