According to Brazilian solar association ABSolar, there are currently more than 300,000 distributed generation PV systems connected to the country’s grid.

The country’s cumulative installed rooftop solar capacity reached 5.4 GW by the end of December. The Indian government now aims to deploy 40 GW of rooftop PV by the end of 2023.

The Ministry of Environment and Climate Action will permit 220 self-consumption projects with generation capacities of no more than 1 MW to be connected immediately. The usual long-winded permitting process has been side-stepped as the government seeks to enable financially-stricken enterprises to benefit from lower energy bills during the public health crisis.

New measures introduced by the government allow households, businesses and public entities to produce and trade clean electricity in low-voltage grids. The new framework is open to power projects with a generation capacity no larger than 200 kW.

The one-off charge for PV systems with generation capacities of 10-100 kW will be almost halved. The fee levied on 100 kW-1 MW arrays will come down by 1-30.7%, depending on system size.

Fire safety engineering researchers have demonstrated increasing the gap between the modules of commercial PV arrays and flat roof surfaces is a decisive factor in reducing fire risks. Experiments have identified a critical gap height below which flame spread rate increases significantly.

The South Korean capital has unveiled a plan to deploy rooftop PV on a million homes and all public buildings. The new initiative is designed to bring the city’s cumulative installed solar capacity to around 1 GW by the end of 2022.

The PVP4Grid project, involving 12 European organizations, wants to increase solar self-consumption system deployment. The project has launched an online tool to enable homeowners to calculate the cost of PV.

Researchers have developed a high-resolution geospatial method of assessing the solar potential of all buildings in the EU and concluded rooftop PV could provide a quarter of the bloc’s electricity needs. The scientists say grid parity for rooftop solar has been reached outside eastern member states with cheap fossil fuel electricity.

Deploying commercial and industrial PV in China without subsidy is already profitable in some areas, according to a new study, but prohibitive soft costs and cheap electricity are the main barriers for such installations in areas where grid parity remains out of reach.
