Residential PV

In its second monthly column for pv magazine, the Becquerel Institute explains that Europe has vast commercial and industrial rooftops suitable for solar, but decades-old structural limits block conventional PV panels, creating an 85 GW untapped potential. Lightweight PV modules, commercially available and up to 50% lighter, can unlock this constrained market, meeting regulatory, economic, and technical needs for solar deployment across the continent.

Energy requirements evolve over time, and solar systems must be designed with adaptability in mind. Design-led innovation supports scalability through modular architectures that allow systems to expand or integrate complementary technologies such as energy storage.

Noida-based Involtics has launched the GTSI series of single-phase hybrid inverters (3 kW/3.6 kW/5 kW/6 kW) for residential solar applications. The inverters work seamlessly with solar panels, batteries (lead-acid and lithium-ion), and the grid to deliver continuous power for household loads.

India’s renewable energy expansion will extend beyond utility-scale projects to distributed renewable energy, green open access and emerging prosumer models enabled by digital platforms and the India Energy Stack as the nation advances toward its vision of becoming a developed nation by 2047.

EcoFlow has unveiled the single-phase Ocean 2 all-in-one battery inverter at Key Energy in Rimini. The system features a more compact 5 kWh LFP battery stackable up to 30 kWh and offering 100% depth of discharge, 3.4 kW discharge power, and IP66 protection.

Indian solar manufacturer Premier Energies has completed the acquisition of 104,550 equity shares of HeliosAnthos Energies, securing 51% of the company’s paid-up equity share capital. HeliosAnthos Energies is a joint venture between Premier Energies and BA Prerna Renewables, formed to expand Premier’s presence in the engineering, procurement and construction (EPC) segment of renewable energy projects.

Oswal Pumps has announced that its subsidiary, Oswal Solar Energy, has secured an order to install 7.46 MWp of grid-connected rooftop solar systems for 3,729 consumers under the PM Surya Ghar: Muft Bijli Yojana.

India installed around 37.8 GW of solar capacity in CY2025. This comprised about 28.6 GW of new utility-scale solar, a 54.6% increase from 2024, and 7.9 GW of rooftop solar, up 72% year on year. Off-grid additions stood at 1.35 GW, compared to 1.48 GW in 2024.

Residential consumers accounted for 76% of rooftop solar capacity additions in 2025, driven by the PM Surya Ghar: Muft Bijli Yojana program.

Rooftop solar is moving from being a supplementary solution to becoming a central component of India’s energy architecture. The next phase of growth will not be defined by panel installations alone but by how effectively generation is integrated with storage, digital intelligence, and grid infrastructure.
