Made in Scandinavia
A wall-mounted solar-air collector with a high-performance super-absorber.
It recirculates indoor air, warms it with available solar energy and returns solar-warmed air to the room.
The collector, duct, fan box, thermostat and connection components, cover plate, and your choice of an adjustable 5–12 V adapter or a 10 W solar module.
Freight is not included.
All orders require 100% payment upfront before processing. We do not offer 30-day payment terms.
For an invoice, we will need your legal company name, business ID or VAT number, company billing address, invoice email and, optionally, a company reference. For company-invoice questions, contact us.
Alternative payment methods, such as bank transfer, cash or selected cryptocurrency, can only be arranged through direct communication with us.
Product details
The collector combines a slim stainless-steel frame with robust, continuous corners. Its seamless folded construction creates a unified edge with fewer exposed joints and a clean architectural finish.
FULLBLACK
Premium materials that protect and shape Fullblack.
Cover · Solar-radiation resistance: 10+ years
Built on Scandinavian engineering.
Easy installation.
The key installation step is making 51 mm wall openings.
Designed for suitable homes, cabins, garages and workshops with an appropriate sun-facing exterior wall. Actual performance depends on sunlight, orientation, shading, airflow, installation and the building itself.
INSIDE
The finer engineering details of what’s inside Fullblack, and how it works its magic, remain our little secret.
Inside Fullblack
Not ordinary black-painted sheet metal. Fullblack uses a purpose-developed, selective super-absorber that captures sunlight while limiting heat radiation towards the colder front glazing. Only 0.2 mm thick, it combines 95% solar absorptance with 5% thermal emittance. Its low thermal mass lets it respond immediately when the sun appears and transfer heat to circulating room air.
Ordinary black paint absorbs sunlight well, but also tends to emit heat strongly. A warmed black-painted sheet can therefore radiate substantial heat towards colder front glazing, leaving less heat for the air. Limiting that loss matters especially in freezing weather.
Fullblack's super-absorber captures 95% of incoming solar radiation while its thermal emittance is just 5%. It absorbs short-wave sunlight strongly and limits long-wave heat radiation. These properties describe different wavelength ranges, not the overall efficiency of the collector.
An absorber must transfer heat quickly when the sun briefly breaks through. Fullblack's 0.2 mm super-absorber has very little mass to heat first, so it responds immediately when sunshine returns and passes heat to the circulating air. Even short sunny spells can contribute useful warmth.
Since the early 2000s
We have developed and manufactured solar-air collectors since the beginning of the 2000s. Our Finnish-born founder brought a practical kind of sisu to the work: keep improving, keep building and do not give up when a more efficient energy solution can be invented.
