Israel Mandates Rooftop Solar on New Buildings

New Law Forces Rooftop Solar on All New Non‑Residential Buildings

Israel’s Energy Ministry has made rooftop photovoltaic (PV) panels compulsory on every new non‑residential building from 1 January 2023. The regulation, part of the 63704 framework, aims to squeeze additional renewable capacity out of limited land and to help meet the country’s renewable‑electricity target for 2030 Lexology. Developers must now submit a solar‑design plan with their building permits, and the panels must be grid‑connected and capable of net‑metering.

Incentive Tracks Accelerate Residential Rooftop Adoption

A public hearing by the Electricity Authority introduced two fast‑track incentive tracks for homeowners, promising a quicker return on investment and a higher feed‑in price for surplus electricity Globes. One track provides a grant that offsets a portion of installation costs for smaller systems, while the other offers an enhanced feed‑in tariff for a limited period. Both schemes are designed to address inflation‑driven price pressures and to support the goal of installing solar on 100 000 roofs.

Net‑Metering and Feed‑In Tariffs Make Solar Profitable

Under Israel’s net‑metering arrangement, electricity generated by a rooftop system first offsets on‑site consumption at the full retail tariff (≈ ₪0.48 /kWh for residential users). Any excess is exported to the Israel Electric Corporation and paid at a fixed feed‑in tariff – currently ₪0.41 /kWh for commercial customers and ₪0.54 /kWh for municipal users SurgePV. A system‑management charge of about ₪0.09 /kWh is applied to self‑consumed power, covering grid‑balancing services.

Market Momentum: 900 MW Added in 2024, Solar Dominates Renewables

Israel installed roughly 900 MW of new PV capacity in 2024, the bulk of it under merchant power‑purchase agreements PV‑Magazine. Solar now accounts for about 88 % of the nation’s renewable‑energy mix, outpacing wind and bio‑energy combined Mordor Intelligence. This rapid growth is being fueled by the new building‑mandate, the incentive tracks, and falling solar‑module prices worldwide.

What It Means for Israel: Payback Example and Climate Impact

Using typical Israeli figures, a 10 kWp residential system in the central region yields about 17 000 kWh per year (1 700 kWh/kWp × 10 kWp). At the residential retail tariff of ₪0.48 /kWh, that electricity is worth roughly ₪8 160 annually. With a turnkey installation cost of ₪3 150 /kWp, the system costs about ₪31 500. Simple payback is therefore ≈ 3.9 years (₪31 500 ÷ ₪8 160 ≈ 3.86). Over a 25‑year lifetime, the system avoids roughly 8.5 t of CO₂ each year (0.5 kg CO₂ per kWh × 17 000 kWh), equivalent to planting about 425 trees.

Analysts note that the new mandate and incentive tracks are turning rooftop solar into a mainstream investment.

Challenges and Outlook: Storage, Grid Integration, and Future Targets

While the mandate boosts capacity, integrating that intermittent generation will require more storage and grid‑balancing resources. In 2023 Israel introduced a supplementary tariff for PV‑plus‑battery installations to encourage behind‑the‑meter storage Chambers & Partners. The government still aims for 20 % renewable electricity by 2025 and 30 % by 2030, meaning rooftop solar must continue to scale rapidly. Policy reviews may consider expanding the fast‑track incentives to multi‑family buildings.

What It Means for Israel (Bottom Line)

For an average homeowner, the new rules and incentives shrink the payback period to under four years and lock in a clean‑energy source that pays for itself many times over. For the nation, mandating rooftop solar on new non‑residential construction could add a substantial amount of capacity by 2030, dramatically cutting reliance on imported fuels and helping meet climate commitments.
