Eskom calls for registration of all grid-tied solar installations

South African utility Eskom is urging consumers with grid-tied rooftop solar to register their systems and integrate them with the national grid, waiving registration fees until March 2026. Off-grid installations must still prove they operate independently.

Powering seawater desalination plants with photovoltaics

A German research team has investigated the feasibility of a large-scale PV-powered seawater reverse osmosis desalination plant in Jordan and has found that keeping the concentrate flow constant is the most appropriate desalination operating mode.

China to switch from FITs to market-oriented renewables pricing

China will replace its feed-in tariff (FIT) system with a fully market-driven renewable energy pricing model by June 2025, shifting wind and solar projects to competitive bidding and market transactions. The reform aims to enhance competition but raises uncertainty over future returns for investors.

Atlas details economic risks of hail damage to US solar sites

VDE Americas’ new hail risk atlas, now available for use on the Esri ArcGIS platform, can compare and evaluate the site-specific hail risk of current and future solar projects across the United States.

Global utility-scale solar additions hit 182 GW in 2024

Utility-scale solar installations reached 182 GW (AC) in 2024, with the top 33 countries now accounting for 765 GW, or roughly 93% of the global total, according to Wiki-Solar.

Slovenia adds 298.8 MW of solar in 2024

Slovenia’s solar market slowed in 2024, but the residential segment maintained the largest share as it adjusted to the phase-out of net metering and a new electricity tariff system.

Cyprus introduces energy storage subsidy scheme

Cyprus’ Ministry of Energy, Commerce and Industry has launched a subsidy scheme for energy storage systems paired with existing renewable energy plants. Eligible projects will be remunerated by feed-in tariffs (FiTs) or net billing systems.

New research suggests optimal tilt angle, overhead height for rooftop PV systems

Researchers in China have investigated the effect of the overhead height and tilt angle on thermal and energy-saving performance of photovoltaic roof and have found that the comprehensive energy-saving efficiency of parallel overhead photovoltaic roofs are optimal in summer and the worst in winter.

The Hydrogen Stream: TalusAg starts green ammonia production in Iowa

Landus and TalusAg have launched commercial green ammonia production in Iowa, backed by US federal clean hydrogen tax credits, while Iberdrola España and BP have started building Spain’s largest green hydrogen project, with 25 MW of capacity.

US startup developing defrost-free residential heat pump for cold climates

TerraVis Energy claims its new heat pump system can achieve a seasonal coefficient performance of 3.5 and deliver 30 C of heat indoors at -50 C. CEO Lorenzo Rossi told pv magazine that the system could be produced at a lower cost than conventional models.
