Australian rooftop PV market continues to thrive
Australia’s rooftop PV fleet continues to grow in the face of uncertainty surrounding the outbreak of the pandemic, posting another big month above 200 MW. Mega-household solar systems are growing in popularity, but retailers and installers can see the storm clouds gathering.
Borehole thermal energy storage for solar
The municipality of Drammen, Norway, has started testing a seasonal PV storage project that uses boreholes in the ground. The operators of the project are using electricity from PV modules to produce heat via a CO2 heat pump and outdoor air. The heat is produced by the CO2 pump during the spring, summer and fall, in addition to heat produced by solar thermal collectors.
