Residential PV

Norway’s solar market experienced a slowdown in 2025, particularly among residential installations. The outlook for 2026 looks more optimistic, thanks to policy reforms supporting larger projects and continued demand from commercial and industrial customers.

A draft decree from Vietnam’s Ministry of Industry and Trade is proposing rooftop solar owners could sell up to 50% of the energy produced back to the grid, in a bid to increase future uptake.

Cyprus wasted nearly half of its distributed renewable generation in 2025, equivalent to 306 GWh, as grid constraints and lack of battery storage forced massive curtailments while solar capacity keeps growing.

Luxembourg’s new subsidy scheme for solar installed on residential buildings by an approved installer deducts the financial aid from the installer’s invoice, meaning customers no longer have to wait for reimbursement.

Croatia’s solar capacity is on course to exceed its wind energy capacity for the first time in early 2026. With utility-scale projects facing regulatory deadlock and the end of net-metering for the residential market, growth is being led by commercial and industrial customers.

Global solar growth is flattening in major markets as oversupply from China and India drives prices down and shifts competition from sheer volume to execution, policy alignment, and system integration. Across the U.S., Europe, and China, energy storage is becoming essential for project viability, making PV-plus-storage and strong EPC partnerships the new basis for winning projects in 2026 and beyond.

Solar farms in New South Wales led the way for Australia’s utility-scale PV energy output in December 2025, generating 1,052 GWh of renewable electricity.

India added an estimated 40 GW of solar capacity in calendar year 2025, driven by utility-scale projects and rooftop growth. Energy storage tendering also picked up pace.

Effective since January 1, 2026, the Solar Accelerated Transition Action Programme (Solar ATAP) aims to build on Malaysia’s previous net metering program’s efforts to maximize the use of rooftops for solar generation by incentivizing consumers to export excess generation to the grid. The capacity limit has been set at 100% of the consumer’s maximum demand, or 1 MW.

A Husqvarna researcher developed a fast, interpretable PV hotspot-detection method using IR thermography and Lab* color-space features instead of heavy neural networks, achieving up to 95.2% accuracy with shallow classifiers. The lightweight system works in real time on drones or edge devices and could save 17,620 kWh and 8.9 tons of CO₂ annually by improving fault detection in solar panels.
