India could have 2.95bn tons of solar waste by 2047
Researchers led by the Indian Institute of Technology Delhi have projected the waste expected from end-of-life solar panels and related components. They assumed 347.5 GW of total installed solar generation capacity would be reached this decade. The academics said the waste would include critical metals worth around $645 trillion, 70% of which could be recovered.
IEA highlights solar’s dependence on Chinese copper processing
The sheer volume of new power lines which will be required to accommodate the rising tide of solar installations ensures copper has been included by the International Energy Agency on its list of minerals which must keep flowing if the energy transition is to stay on course. And it’s not production that’s the potential bottleneck.
Concrete battery for applications in buildings, rooftop PV
A prototype of a cement-based battery has been developed in Sweden for potential applications in buildings. Its creators claim it could become a solution to store electricity from rooftop PV and they do not exclude that it could also be used for the storage of large-scale renewables.
India again ranked the world’s most attractive solar market by Ernst & Young
The nation maintained the highest score of 62.7 for solar in the latest edition of Ernst & Young’s renewables attractiveness index. It ranked third for overall renewable energy investment.
IEA calls for annual additions of solar PV to reach 630 GW by 2030
According to the International Energy Agency, most of the global reductions in CO2 emissions between now and 2030 would come from technologies available today. In a recent report, the agency sets what it described as a “cost-effective and economically productive” pathway resulting in an energy economy “dominated by renewables like solar and wind.”
Rooftop solar uptake in India: Challenges and way forward
Poor and piecemeal implementation of net metering policies is a major roadblock for the uptake of rooftop solar system in India, according to a new report by Asian Development Bank.
Renewables accounted for 64% of India’s electricity generation capacity addition in FY21
India added 7.7 GW of new renewable energy (RE) capacity in FY2020-21, out of which 5.5 GW (71%) came from solar (grid-scale and rooftop) alone. Overall power generation capacity addition for the year stood at 12.1 GW.
Solar 101: Working the angles to maximize your solar system’s output
Using Normal, Illinois, as a … well, normal … case study, we look at how a roof’s latitude, pitch, and azimuth affect energy output.
Meyer Burger unveils 400 W heterojunction solar module
The solar module will be available in three versions – white, black, and glass-glass. The products have an output of up to 400 W, but when the bifacial effect is optimally used, the output of the glass-glass module can reach up to 430 W. Both the white and black modules weigh less than 20 kg.
Solar 101: Attaching your PV system to your roof
A solar racking system’s strength is determined in part by the metal racking, but it also depends on the roof’s underlying structure. Rafters and any supporting structures must be strong enough to withstand your region’s maximum wind and snow loads.
