Residential PV

While subsidies have provided an important early boost, the future of residential solar affordability rests on financing models that expand access consistently. Loans create a pathway for households across diverse income brackets and geographies to invest in clean energy without waiting for government support.

Sandia National Labs researchers have created a new dataset on the rates and types of rooftop PV connector failures. Their analysis has shown that tight wire bending radius, extra dirty connectors, and loose nuts are the most common failure causes in 6,276 connectors deployed between 2014 and 2017 across seven U.S. regions.

Solar represented 75% of grid capacity additions in the first half, followed distantly by wind and natural gas, said new data from the Federal Energy Regulatory Commission.

India’s Goods and Services Tax (GST) Council has announced a reduction in the GST rate on solar cells—whether or not assembled into modules—from the current 12% to 5%. The revised rates will take effect from September 22.

Adopting rooftop solar has never been simpler, with 100% digital, collateral-free loans tailored for middle-income households. From instant, paperless approvals to flexible options like zero-cost EMIs or hybrid plans, the process ensures ease at every step.

The Chinese company said its new microinverter supports four independent MPPT inputs with DC input currents up to 18 A.

Solfin Sustainable Finance, a solar-focused non-banking finance company (NBFC) backed by Waaree, and Japanese Financial Institution, have entered co-lending partnership to provide working capital finance to solar panel dealers and rooftop solar finance to end consumers.

India added 2.8 GW of rooftop solar capacity in the first half (January–June) of calendar year 2025, marking a 155% year-over-year increase compared to the 1.1 GW installed during the same period in 2024, according to Mercom India’s newly released Q2 2025 India Rooftop Solar Market Report.

SolarSquare has installed more than 250 MW of rooftop solar capacity, including about 100 MW in the residential sector and 150 MW commercial and industrial.

A study conducted by the German development agency Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) in collaboration with India-based think tank the Center for Study of Science, Technology and Policy (CSTEP), found that India has the potential for more than 300 GW of building-integrated photovoltaic (BIPV) systems on its existing buildings alone. Moreover, according to a World Bank report, 70% of the buildings India will need to become a developed nation by 2047 are yet to be constructed, underscoring the vast future potential for BIPV systems in the country.
