Because the solar modules themselves are practically invisible, Roofit.Solar''s roofs also work for protected buildings and a variety of more demanding architectural styles, giving them the edge when it comes to speeding up the spread of solar energy
In a groundbreaking move, Estonian solar energy company Solarstone unveils its state-of-the-art Building-Integrated Photovoltaics (BIPV) factory, establishing itself as the largest of its kind in Europe by production
Solarstone is reinforcing Estonia''s commitment to sustainable energy solutions by opening Europe''s largest solar roof factory to produce 14 times as many building-integrated solar roofs as Tesla in the U.S.
When Solarstone started in 2015, the solar panel market was essentially mature, innovation was driven by materials science, but there were limited possibilities for the application of solar panels.Existing solar solutions available on the market were either too expensive or unfit for various reasons, mainly poor aesthetic appeal. This created an immediate understanding by
Solarstone, a solar roof manufacturer based in Viljandi, Estonia, is continuing its partnership with the Solaride project for the third consecutive season. Since 2020, this collaboration has led to
Estonia has seen a significant increase in its solar power capacity in 2022, becoming one of the leaders in solar power per capita among EU members. With growing investments and innovative startups, it now aims to be fully green-powered by 2030.
This impressive solar project is currently the largest PV project in the Baltic States and in Estonia in particular. At full load, it will cover around a tenth of Estonia''s electricity needs. Immediately after signing the contract, we have already
In a groundbreaking move, Estonian solar energy company Solarstone unveils its state-of-the-art Building-Integrated Photovoltaics (BIPV) factory, establishing itself as the largest of its kind in Europe by production capacity. The factory has the capacity to assemble 13,000 integrated solar panels per month.
Estonian startup Solarstone has developed two solar tiles with an efficiency of up to 19.5% and an operating temperature coefficient of -0.41% per C. It recently secured €10 million in funds to...
Already active in 22 countries, Roofit.Solar is an Estonian CleanTech scale-up offering building-integrated solar roofs that generate solar energy while preserving aesthetics. Rooftop solar—so hot right now
Solar is one of the most sustainable and accessible energy sources. Since 2020 we have completed development and construction of more than 62MW of solar capacity. We have more than 744MW of ongoing projects around Estonia in different municipalities which will be completed by the end of 2024.
Solarstone, a solar roof manufacturer based in Viljandi, Estonia, is continuing its partnership with the Solaride project for the third consecutive season. Since 2020, this collaboration has led to international competition participation and opened up new opportunities for

This impressive solar project is currently the largest PV project in the Baltic States and in Estonia in particular. At full load, it will cover around a tenth of Estonia''s electricity needs. Immediately after signing the contract, we have already started with the first works, completion is planned for the end of Q3/2026.

Solarstone is reinforcing Estonia's commitment to sustainable energy solutions by opening Europe's largest solar roof factory to produce 14 times as many building-integrated solar roofs as Tesla in the U.S. The factory can assemble 13,000 integrated solar panels per month.
Solarstone – the Estonian solar roofing startup secures €10 million in funding. With these funds, Solarstone intends to expand building-integrated solar PV solutions across Europe and beyond. The company’s mission is to make building-integrated solar solutions the standard in residential and infrastructure construction.
Estonia has seen a significant increase in its solar power capacity in 2022, becoming one of the leaders in solar power per capita among EU members. With growing investments and innovative startups, it now aims to be fully green-powered by 2030.
That makes another record-breaking year for solar on the continent, with a total of 10 GW more capacity added than expected. Regarding solar power per capita, Estonia has emerged as one of the new leaders. The country is ranked 6th among 27 EU members, with 596 Watt per capita in 2022, jumping from 405 in 2021.
Since 2020 we have completed development and construction of more than 62MW of solar capacity. We have more than 744MW of ongoing projects around Estonia in different municipalities which will be completed by the end of 2024. We are also working to incorporate storage systems to provide electricity when the sun is not shining.
So far, it has been a key objective of Estonian energy policy. Being a Nordic country with less sunlight than in Western and Southern Europe, Estonia has achieved a solid place at the top with its 1,923 sunny hours in the year.
The European energy storage market is booming with Germany leading residential adoption (+58% YoY) thanks to €500/kWh subsidies. Italy's new tax credits drive 5.2GWh commercial deployments, while UK grid-scale projects exceed 8GWh with 2-hour duration systems. Key selection criteria: German-certified safety (VDE-AR-E 2510), 10+ year warranties, and VPP readiness. Top-performing products include Sonnen's hybrid inverters (98% efficiency) and BYD's Blade Battery (12,000 cycles @80% DoD). For snowy regions like Scandinavia, consider Huawei's -30°C compatible systems. France mandates carbon footprint declarations - Sungrow's ISO-14067 certified solutions gain preference.
For European homeowners, 5-10kWh systems with 3-phase compatibility are ideal. Top picks: 1) Tesla Powerwall 3 (13.5kWh, 97% round-trip efficiency) for smart home integration; 2) LG Chem RESU Prime for compact urban installations; 3) SMA Sunny Boy Storage for retrofit projects. Critical features: EU-made battery cells (exempt from CBAM tariffs), dynamic tariff optimization (like Octopus Energy integration), and fire-safe LiFePO4 chemistry. Southern Europe demands 85%+ depth of discharge capability, while Nordic markets require -25°C operation. Always verify CEI 0-21 compliance for Italian grid connection and EnWG certification for German feed-in.
