After two months of module price decreases in Europe, all solar module and inverter types have gone up, according to the latest PV Index report from online solar marketplace sun.store.
TOPCon bifacial modules saw a monthly increase of 1.5% but remained the cheapest with an average price of €0.116/Wp (US$0.132/Wp). The technology also registered the lowest monthly increase across all technologies, with Full Black at the opposite end, with a 13.3% increase to an average price of €0.144/Wp in October 2026.

As shown in the chart below, the price of back contact and TOPCon monofacial modules are both at €0.131/Wp, however the monthly price increase was of 3.9% and 9.2%, respectively.
“Module pricing kept splitting along the premium line in October 2026. Full Black posted the strongest gain of the month and is now the most expensive segment in the index,” said sun.store
Compared with monofacial TOPCon modules, sun.store added that bifacial TOPCon modules remain the cheaper option for standard utility-scale modules “by a widening margin”.
When it comes to the supplier ranking over the three months to October 2026, the top five remain unchanged from last month with all five being Chinese module manufacturers. Trina Solar remains the top supplier, followed by Aiko, JA, Jinko and LONGi.
Smaller hybrid inverter price surpasses €100/kW
Similar to solar modules, inverter prices increased in October across all types. The price of smaller hybrid inverters, between 1-20kW, increased by 9% from last month and reached €103.16/kW. The highest across the four types.
Larger hybrid inverters had the largest monthly price increase, with a 9.5% change for an average of €65.63/kW.
Smaller string and on-grid inverters remained nearly stable with only a 0.2% increase for an average price of €54.05/kW, while prices of larger string inverters rose by 7.9% to €23.76/kW.
“Hybrid pricing firmed across both size bands. Larger commercial units remain by some distance the most competitively priced part of the inverter market on a per-kW basis,” explained sun.store.
Finally, the demand for solar modules in Europe remains below historic averages since June 2026 and dipped from 67 in September to 65 in October, according to PV Index’s Purchasing Managers Index (PMI), which is sun.store’s monthly solar demand indicator.
45% of surveyed buyers plan to buy more modules in November, while 41% expect no change and 14% plan to buy fewer modules in the coming month.
