The comparison of two solar cladded roofs in Sydney, Australia, one bare beneath its panels and the other adorned with native grasses and plants, has found the panels on the green roof were, on average, 3.63% more efficient, producing an average daily output 13% greater than the conventional roof. The improvements are believed to stem from the lower temperatures on the green roof, thanks to its plants – which also provided a plethora of additional benefits.
An Indian-Malaysian research group has investigated the effectiveness of several passive cooling techniques for solar panels, including the placement of plants around the modules or coir pith underneath them, both of which, surprisingly, offered good performance in terms of temperature reduction and power yield.
The switch from fossil fuels and nuclear will bring a jobs dividend thanks to the greater labor-intensity of renewables plants, according to a paper published by Finland’s LUT. However, the jobs dividend is unlikely to be evenly spread around the world, with Europe set to be a big winner.
Bids are invited to build the solar project in ‘design-build-demonstrate-transfer’ mode anywhere in Odisha. The electricity produced will be utilized for captive consumption of Mahanadi Coalfields Limited through long-term open access. Bidding closes on September 1.
GoodWe supplied 136 units of its MT80KW inverters for Microtech Rollers’s 15 MW of solar projects in the Saurashtra region of Gujarat. The inverters are currently generating 27 GW of electricity per annum.
The solar plant in the Beed district will supply power to leading corporate customers under the captive structure.
India’s commercial and industrial solar sector added 501 MW of solar capacity in the January-March period of 2021, taking the cumulative C&I PV capacity to 10,485 MW as of March 31, 2021.
The Haryana-based developer will construct, own, and operate up to 500 MW of hybrid renewable energy generation capacity to meet the requirements of RackBank’s hyper-scale data center.
The energy payback time of a silicon PV rooftop system mounted in India is only 0.44 of one year (160.6 days), compared to 0.53-0.67 year in Africa, 1-1.3 years in Europe, and 1.42 years in Canada, reveals a world map by German research body the Fraunhofer Institute of Solar Energy Systems (ISE). For the calculation, the report authors considered the installation used a typical, Chinese-made, 60-cell, PERC, 19.9%-efficient solar module.
Copenhagen Infrastructure Partners and Amp Energy have signed a US$200 million investment pact with each partner committing to $100 million. The investment will allow Amp Energy to add 1.7 GWp of utility-scale and commercial and industrial renewable energy projects.
