About
Our solar panels
New-builds or renovation projects. Solarstone® building-integrated solar panels (BIPV) perform as regular roofing material while harnessing solar energy.
SolarStone® replaces traditional roof tiles, shake or shingle roofs with innovative solar modules.
SolarStone® panels do not require any expensive mounting systems. Modules are installed directly to wooden battens, PV cables are connected to the inverter and voilà! Locally produced and consumed energy is most viable and sustainable way to combat climate and energy challenges.

PRODUCTS

MODERN
TILED ROOF
SolarStone® building integrated modules interlock with any concrete or clay tile. 2 different size and output modules (85W & 105W) are available to match with comprehensive selection of tiles available on the market.

AESTHETICS
STANDING SEAM
Latest addition to SolarStone® product portfolio is module for existing standing seam steel roofs. Depending on seam properties the module output varies from 140W to 180W. Modules are compatible with Toode AS and many other profiles.

ECONOMICAL
FULL ROOF
Solar panels can be effectively used for erecting full PV roof, be it a renovation or a new-build project. 290W … 375W standard-size modules are fitted with innovative framing, which renders regular solar panels into weatherproof roofing system.
ADVANTAGES
AESTHETICS
BIPV helps maintain the original design of the building.
SPATIAL EFFICIENCY
BIPV promotes resourceful use of land and existing spaces of an existing building.
WEATHERPROOF
BIPV performs as regular roof with all the weatherproofing properties.
EASY TO INSTALL
BIPV follows similar installation principles as regular roofing materials.
EFFICIENT
BIPV promotes sustainable use of raw materials.
SUSTAINABLE
BIPV helps convert a building self-reliant for energy requirements.

Invisible
SolarStone® building integrated panels fit with any type of roofing material and you may not notice the difference as the panels are invisible to bare eye.
Solarstone modules perform as 2-in-1 roofing system as you will benefit from uninstalled tile material and roofing works.
We challenge traditional building concepts. We believe that small scale renewable installations play key role in the future of housing and energy transition.

Robust
Demonstrating the robustness of SolarStone® modules we have:
- conducted hail tests with ice balls cannoned at 130 km/h
- dropped the panel from 1,5m.
- performed snow load tests for 250kg/m².
SolarStone® panels have passed safety tests and conform to all relevant standards.
Monocrystalline cell Solarstone® modules are produced of high-quality components. We are constantly striving for better output and aim to improve the visual appeal of solar future.

Quality
Solarstone® solar panels are manufactured in Estonia using the most modern components of the PV industry. In Viljandi, production is located on an area of 1200 m2, where you can visit with prior notice and get acquainted with the product range.
The entire production process, from soldering the photocells to framing the finished modules, takes place under one roof - 10 highly qualified engineers and skilled workers are involved in the production of the panels.
The panels are installed with the help of highly selected partners, in special cases by ourselves. Today, reference objects can be found in every part of Estonia and in six foreign countries.
