European Solar Module Prices Stabilize in July

Prices held steady in July 2026

Solar module prices across Europe were essentially flat in July 2026, following earlier price increases that had concerned installers. The latest PV‑Magazine index showed negligible month‑on‑month changes for full‑black, low‑cost and other modules, while back‑contact cells kept modest upward pressure because demand still outstripped supply.

Back‑contact modules remain scarce

Back‑contact modules with efficiencies above 24% continue to be the lone outlier. Their high‑power variants are in short supply, keeping prices slightly higher in that niche. Only three Chinese factories – AIKO, Longi and TCL – are currently producing them at scale, and patent‑licensing disputes add further uncertainty. Nevertheless, this segment still represents a tiny slice of total market volume, so its price dynamics have little effect on the overall index.

Manufacturers eye perovskite and tandem cells

The industry is already looking beyond TOPCon. Perovskite‑silicon tandem modules, which have already demonstrated efficiencies just over 25% in pilot lines, are being field‑tested by Oxford PV and could reach 27% by next year. If the material‑stability hurdles are solved, efficiencies above 30% are theoretically possible, opening the door to smaller rooftops delivering the same power. Mass‑market launch is projected for late‑2027 or early‑2028.

Production capacity pressure forces price discipline

Because manufacturers have invested heavily in upgraded TOPCon lines, they now run those factories at very high utilization. Idle capacity is costly, so the previous production cuts that helped prop up prices are being rolled back. The result is a modest downward trend for TOPCon modules and a stable‑or‑slightly‑higher outlook for back‑contact products.

What it means for Israel

For Israeli homeowners, the European price pause translates into a modest cost benefit. Using the typical Israeli figures – ₪3,150 per kWp install cost and a 1 kWp system yielding about 1,700 kWh / kWp / year in the central region – a modest reduction in module price would shave roughly ₪158 per kWp from the upfront bill. On a 10 kWp rooftop, that’s a saving of about ₪1,580, cutting the simple payback period from about 3.9 years to roughly 3.6 years at the residential tariff of ₪0.48 /kWh. Homeowners can therefore expect a slightly quicker return on investment without waiting for the next generation of perovskite‑based panels.

Outlook: modest price drift, tech‑driven growth

Overall, the market is likely to see stable or gently falling prices for TOPCon modules through the rest of 2026, while back‑contact cells may stay a touch pricier due to their niche appeal. The real game‑changer will be the commercial rollout of perovskite‑tandem technology, which could compress system sizes and further drive down balance‑of‑system costs once the stability issues are resolved.
