Solarstone opens the largest solar roof factoy in Europe

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. Annually, this supplies 6,000 homes with 10 kW solar roof installation, enough to power an average household. Compared to Tesla, Solarstone is able to produce 14 times more solar-powered roofs. In the last seven years, Tesla has installed solar roofs for 3,000 homes in the U.S.

According to the CEO of Solarstone, Silver Aednik, the new factory helps to drive the industry transformation globally. The plant’s annual production capacity of 60 MW bolsters Solarstone as the leading building-integrated photovoltaics production unit in Europe.

Solarstone’s implementation of advanced precision machining enables easy adaptation to the specifications of top-tier solar panel manufacturers known for their high-quality standards. This ensures that each product consistently meets the company’s strict criteria.

The new factory features an advanced A+ rated testing station, ensuring all solar panels meet industry standards and offering personalised performance reports to customers.

The new factory is backed by investments from Estonian-based companies Sunly and Biofuel.

 

Shaping the future

The Solarstone product goes beyond a standard rooftop solar panel. Their building-integrated photovoltaics (BIPV) serve a dual purpose as both a roofing material and an energy generator, turning sunlight into electricity.

“We offer a 2-in-1 solution that is markedly more eco-friendly. Traditional methods construct the solar roof twice: initially creating a ‘base roof’ and adding a ‘panel top layer’. But our innovative methodology is not just a revolutionary stride in sustainable building. It also underscores our dedication to eco-friendly solutions. And we achieve this without sacrificing functionality or aesthetics,” notes Toomas Kresla, Head of Manufacturing at Solarstone.

The 2029 mandate by the European Union for solar energy-producing roofs in new constructions represents a pivotal shift in energy policies and building regulations, reflecting a worldwide transition towards more efficient and intelligent energy solutions. Solarstone is an excellent example of repurposing underutilised rooftops into valuable energy assets, aligning with the growing trend of optimising urban and industrial spaces amid ongoing discussions in certain European countries regarding the prohibition of solar parks on agricultural lands.
