Estonia-based solar roof company Solarstone has completed 700 solar roof installations in 8 countries. Recently Solarstone has also raised a good amount of financing for growth. With the help of a local asset manager, the company has raised €10 million to support future plans.
An email to CleanTechnica shares that Solarstone plans to use these funds to expand building-integrated solar PV solutions across Europe. The expansion will also help set up development for installations outside of Europe. The company’s mission is to make building-integrated solar solutions the standard in residential and infrastructure construction.
According to Silver Aednik, co-founder and CEO of Solarstone OÜ, energy production and consumption patterns are undergoing a major shift, with prosumer-generated capacities making up for the shortcomings of centralized power generation.
“The shift has led many to look at adding their manufacturing capacity to where they live. Solarstone’s technology removes all barriers to making this possible, as it becomes profitable, beautiful and climate-conscious by adding solar power directly to where they live,” said Silver.

The company actively recruits proptech experts to grow private and corporate segments. They will develop the teams in Estonia and other strategic markets. At the same time, Solarstone is investing in software solutions to help construction industry stakeholders design and procure solar power plants efficiently.

“Existing BIM models make all the work of architects and engineers easier. Soon, the implementation of modern satellite technology and a comprehensive ecosystem platform will provide simple tools to design and deliver the most suitable integrated solar power plant for all market players,” added Silver.

The leader of this second round and most recent investment was Biofuel OÜ. Sunly, a leading renewable energy company in the Baltic States, joined the company in 2019. Biofuel OÜ, a wealth management company, is focused on eco-friendly wood refining and sustainable forest management. The focus on sustainable energy management and production is in line with this investment.
“sunstone distinguishes itself from other providers of solar solutions with smart technology, which helps to avoid unnecessary material and production costs when creating modern roofs. Innovative software and a proprietary hardware component give a good impulse to the green revolution”, says Andreas Laane, CEO of Biofuel.

PV magazine reports on the specifications of the solar tiles from the 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.
“One of the two solar panels, called Solarstone 90 W, has a current conversion efficiency of 19.5%, an open circuit voltage of 11.22 V and a short circuit current of 9.58 A. It has dimensions of 1,530 mm x 395 mm x 31 mm and weighs 7 kg. The tile is based on eight 156mm x 156mm cells and 3.2mm prismatic glass. The second tile, called Solarstone 108 W, has a larger size of 1,824 mm x 389 mm x 22 mm and a weight of 8 kg. It has an efficiency of 19%, an open circuit voltage of 12.9 V and a short circuit current of 8.39 A.”
