Residential PV

Researchers in India have combined PV generation with heat produced by an earth-to-air heat exchanger to provide buildings with space heating and cooling. They say the proposed system could result in an annual energy gain of 8116.7 kWh.

IEA-PVPS has used an improved methodology to determine that newly installed PV capacity in 2022 must be somewhere between the 190 GW calculated by the International Renewable Energy Agency (IRENA) and the 268 GW announced by BloombergNEF. Its new “Snapshot of Global PV Markets 2023” report was built on data from a range of sources, including grid-connected and off-grid figures.

Dutch startup Airturb has developed a 500 W hybrid wind-solar power system featuring a vertical axis wind turbine and a solar base hosting four 30 W solar panels. The system can be used for rooftop or off-grid applications.

A new report says the time is ripe for Bangladesh to increase renewable energy-based generation capacity to reduce costly fossil-fuel imports and drive down subsidy burdens on the power sector. It finds the nation would need to consistently invest $1.53 billion to $1.71 billion annually until 2041 to build a 40% renewable energy capacity of the electricity demand of 61,866 MW in 2041.

China’s DAH Solar has developed a turnkey solar system with a plug-in connection for residential applications. The kit can reach a maximum size of 2,279 mm × 1,134 mm × 32mm and weighs up to 59.8 kg.

JMK Research analysts expect India to add 14 GW of new utility-scale solar capacity and 2.8 GW of rooftop (onsite) PV in the twelve months ending December 31, 2023.

Norway’s Over Easy says its pilot vertical PV system in Oslo achieved remarkable performance throughout a snowy winter. In 2022, the vertical array generated 1,070 kWh per kilowatt installed, which the company says compares to around 800 kWh per kilowatt installed for a conventional rooftop array.

India attracted around $10 billion of annual investment in the renewable energy sector over the last five years. High economic growth and a stable commitment to decarbonization have drawn the attention of major organizations and investors from around the world. 

Rajasthan, Gujarat and Karnataka account for over 50% of the cumulative installed solar capacity.

Indian Renewable Energy Development Agency Ltd (IREDA) disbursed loans of INR 16,320 crore and sanctioned INR 32,578 crore for renewable energy projects, in FY 2022-23.
