Residential PV

A study by engineers at UNSW, published in the Renewable Energy journal, shows that aerosols and greenhouse gas emissions reduce the productivity of photovoltaic installations and that this differs according to the global region.

Madrileña Red de Gas is testing a heating system prototype developed by Germany company Vaillant that uses exclusively green hydrogen. The 25 kW system is equivalent in shape and size to a current natural gas heating system.

While the benefits of solar adoption are evident, challenges persist. The irregularity of solar power and the lack of efficient storage technologies remain primary concerns. The upfront costs of solar installations, though decreasing, remain a barrier for many. Complex regulations and bureaucratic hurdles often deter individuals and businesses from embracing solar energy. Addressing these challenges demands a concentrated effort.

BloombergNEF says historically low module prices will drive the global solar industry to record installations in 2023.

Netherlands-based developer of lightweight PV systems, Rable Group, claims its new rooftop PV solution can be installed in 20 minutes without the need for special permitting or modifications to the fuse box.

Goldi Solar has announced it will power the residences of the rescued workers with solar energy.

Scientists in Korea have proposed a simple methodolgy to tranform existing PV systems into photovoltaic-thermal (PVT) arrays. They claim the new design offers a cheaper alternative to expensive PVT systems, while enabling easier and faster deployment.

India’s solar installations for the Jan-Sept period in 2023 stood at 8.5 GW, 25% less year-on-year. The nation is expected to install an overall 11 GW in the current calendar year.   

Exide has forayed into lithium-ion-based home power backup systems with the launch of wall-mount lithium battery inverters in 450 W and 720 W sizes. 

Germany installed 11.7 GW of new solar capacity between January and October 2023, with 1.23 GW added in October alone, bringing the nation’s cumulative installed solar capacity to 79.2 GW.
