Israel Mandates Solar Panels on New Homes in Landmark Renewable Energy Reform

Israel is set to implement one of its most significant renewable energy reforms to date, as a new Ministry of Energy regulation will require solar energy systems on the roofs of all newly built homes with roof areas exceeding 100 square meters. The regulation comes into force on December 12, 2025, marking, according to officials and industry leaders, a transformative moment for the country’s solar sector.

Aviv Pepper, CEO of Colmobil Energy, Israel’s largest installer of residential rooftop solar systems, said the regulation will dramatically expand the nation’s renewable capacity. “The Ministry of Energy’s new regulation will lead to tens of thousands of additional photovoltaic installations, totaling 3,000 megawatts by 2040,” Pepper stated.

Step Toward Israel’s 2030 Renewable Energy Targets

The new rules form a central pillar in the government’s effort to reach 30% renewable energy production by 2030. According to the Energy Ministry, widespread adoption of rooftop solar will significantly reduce air pollution, cut household electricity costs over the long term, and improve the country’s resilience during emergencies by enabling local power generation.

Officials say that placing production close to consumption will save the state billions of shekels in electricity grid expansion and prevent the allocation of tens of dunams of land for new transmission infrastructure.

High Demand Expected for Home Solar Systems

A recent study on rooftop installations found that Israel adds roughly 10,000 new private homes each year. With an average system price of about 70,000 shekels, the annual value of potential installations stands at approximately 700 million shekels.

Pepper noted that the regulation aligns with both environmental and economic interests: “This is a move that benefits the state, the market, and the homeowner.”

Industry Leader Poised to Expand

Colmobil Energy, the solar energy arm of the Colmobil Group, is expected to be one of the major beneficiaries of the regulatory shift. The company has seen rapid growth in recent years as rooftop solar gained traction among homeowners seeking cleaner energy and greater independence from Israel’s national grid.

With the regulation now set for implementation, the industry is preparing for substantial expansion across Israel’s residential construction sector.
