Residential PV

All solar is equal, but rooftop solar is more equal

Cornell Researchers have found that upstate New Yorkers prefer rooftop solar to community solar under 50 acres, but opinions are split 50/50 over large-scale ground mounts. The distaste for utility-scale solar is strongest when converting forests, public land and productive farmland.

Modeling method for agrivoltaics in greenhouses

Spanish researchers have developed a new modeling technique to assess the performance of semi-transparent PV systems for greenhouses. Their novel approach considers the broadband and spectral content of the irradiance, the solar cell technology and its performance metrics, and the relationship between the photosynthetic rate and the effective photon flux that falls on the crops.

New German government presents package of measures to support PV

The new package includes an increase in solar capacity, to be allocated through tenders, and the mandatory installation of PV systems in all commercial buildings.

PV set to be largest source of new US generating capacity in 2022

About 46% of all new generating capacity in the United States is expected to be PV this year, giving it the largest share of the new US generation mix.

Solar up in Belgium in 2021 but will have work to do as nuclear shutdown nears

Electric transmission company Elia Group noted a bigger slice of the generation mix occupied by nuclear last year, just hours after a London-based consultant said the nation was on track to switch off its reactors before 2026.

Residential building fully reliant on hydrogen for space heating, hot water

The campus of the Delft University of Technology (TU Delft) in the Netherlands is currently hosting a retrofitted existing building provided with heating by an H2 heating boiler in the attic. The boiler is linked to an underground hydrogen system.

India may add 12.5GW of solar in 2022-23

Indian ratings agency ICRA expects the solar boost based on the backlog of PV projects awarded by central and state electric utilities.

Brazil introduces new rules for distributed generation, net metering

The Brazilian authorities have introduced new rules to ensure that PV systems below 5 MW in size will still be eligible for net metering tariffs until 2045. A grid fee for prosumers will go into effect from 2023, but the economic profitability of rooftop PV and small solar parks is expected to remain high.

South Korea installed 4.4 GW of PV capacity in 2021

South Korea’s cumulative installed PV capacity hit 22 GW at the end of 2021, according to provisional figures from the Korea Energy Agency.

New Yorkers fund 4 GW of solar for less than a cup of coffee per month

The New York Governor’s Office has submitted its financial proposal for 4 GW of distributed solar capacity by the year 2030, at an expected cost of $0.00082/kW.
