Residential PV

A research team led by Washington State University has developed a cloud-based system for trading and sharing energy from solar panels and batteries within a neighbourhood. The concept displayed potential energy cost savings of around 12% over a five-day test period.

Brazil installed 6.4 GW of distributed solar capacity between January and September 2025, down 12% from the same period in 2024, and current installation rates point to about 8.5 GW for the full year as residential and commercial segments weaken and regulatory reporting delays persist.

Japan’s solar module shipments reached 1.28 GW in the first quarter of fiscal 2025, supported by strong residential demand and ongoing dominance by foreign manufacturers, with domestic production limited to just 5% of total output, according to the Japan Photovoltaic Energy Association (JPEA).

The phasing out of net-metering for solar installations is incentivizing a growing number of citizens to install residential battery storage systems in the Netherlands. Analysts are predicting the upward trend will accelerate in the coming years.

Scientists in China have developed an optimized energy management strategy for a wind-PV hybrid heat pump system that uses both thermal and electric energy storage. Using different seasonal interaction management strategies, they simulated four operational cases.

Small-scale rooftop solar accounts for more than 800 MW of Ireland’s 2.1 GW of installed solar PV capacity. The country recently surpassed the 2 GW installation milestone, and subsidies for domestic solar remaining at the current level for the coming year is a win for the industry.

In a new weekly update for pv magazine, Solcast, a DNV company, reports that India’s solar generation potential was significantly hampered during September and October due to an intensified southwest monsoon, resulting in a 15% decrease in irradiance compared to the long-term average.

The Chinese company said its 2,016 Wh portable LiFePO₄ energy-storage system is expandable to 22,176 Wh with additional battery modules. It delivers 2,400 W output, offers 16 ports, app-based control, and includes built-in audio and lighting features for home, travel, and off-grid use.

Viridian Solar, a UK-based roof-integrated solar PV specialist, announced new flashing products to seamlessly integrate its solar panels with skylight-style windows made by Keylite Roof Windows.

The International Energy Agency (IEA) says that Australia installed 5.2 GW of solar capacity in 2024, bringing the national total to 40 GW across distributed and utility-scale systems.
