One to four hours of battery storage for a solar power facility can significantly increase site revenue in areas with high population density or abundant solar energy. However, the added value diminishes with storage capacities exceeding four hours.

UK-based Wondrwall says its new heat pump has a coefficient of performance of up to 4.99, with an inlet-outlet temperature of 30 C to 35 C. The system is based on the company’s AI-powered Home Energy Management System (HEMS) to efficiently manage household energy flows.

PV data consultancy Wiki-Solar says the world’s top solar developers have added nearly 50 GW of new solar capacity since early 2023, raising their cumulative capacity to 146.7 GW – more than one-fifth of the global total.

The UK government has confirmed new hydrogen plans, while RWE says it has secured construction and environmental permits to build a 100 MW electrolyzer in the Netherlands.

Researchers from Greece have developed a PV forecasting technique for prosumer schemes using federated learning, a machine learning method that sends local model updates to a central server for correction. Their simulations show surprising results compared to centralized forecasting.

China’s National Energy Administration (NEA) says solar installations reached 160 GW between January and September 2024, with cumulative capacity hitting 770 GW by August.

New US incentives support solar manufacturers and encourage the domestic build-out of the earlier stages of the solar supply chain.

Through a new methodology based on Decoupled Net Present Value (DNPV), a German research team has found that residential photovoltaic systems were not economically viable under most market conditions at the beginning of 2023. Although lower modules prices have significantly improved system profitability in recent months, several influencing factors that change over time may still have an impact on revenue.

French independent power producer (IPP) Neoen is increasing its investment in Irish solar with its Ballinknockane project in Ireland, which is now under construction. The company already operates three solar farms in the country totaling 58 MW and recently secured two new projects totaling 170 MW in the latest Irish energy auctions.

The United States continues to set quarterly records for energy storage installations across each key market segment, said a report from Wood Mackenzie.
