New photovoltaic tiles from Estonia – pv journal International

Estonian startup Solarstone has developed two photo voltaic tiles with an effectivity of as much as 19.5% and an working temperature coefficient of -0.41% per C. It not too long ago secured €10 million in funds to broaden gross sales throughout Europe.

Estonian startup Solarstone introduced it has not too long ago secured €10 million ($10.1 million) in its second financing spherical. “With these funds, Solarstone intends to broaden constructing built-in photo voltaic PV options throughout Europe and past,” the corporate stated in an announcement launched. “The funding follows the 700th photo voltaic roof set up in eight nations.”

Its building-integrated photovoltaic (BIPV) product portfolio consists primarily of three merchandise – two kinds of photo voltaic tiles with a nominal energy of 90 W and 108 W, respectively, and a rooftop PV system. “We use photo voltaic panels from the world’s prime producers for our full photo voltaic roof. We add proprietary and patented aluminum expertise, known as Click-On body, that turns a traditional photo voltaic panel into the weatherproof roofing materials,” Solarstone CEO, Silver Aednik, instructed pv journal. “The result’s an aesthetically pleasing two-in-one photo voltaic roof.”

According to the producer, the Click-On equipment tackles the principle points BIPV has been going through, that are compatibility, scalability and complexity of set up. The Click-On profiles are reportedly appropriate with the merchandise of most Tier-1 photo voltaic panel producers. “The profiles might be fitted on-site and even essentially the most complicated rooftop configurations might be dealt with with ease,” the corporate stated.

One of the 2 photo voltaic tiles, dubbed Solarstone 90 W, has an influence conversion effectivity of 19.5%, an open-circuit voltage of 11.22 V, and a short-circuit present of 9.58 A. It has dimensions of 1,530 mm x 395 mm x 31 mm and weighs in at 7 kg.

The tile depends on eight cells measuring 156 mm x 156 mm and three.2 mm prismatic glass.

The second tile, known as Solarstone 108 W, has a bigger measurement of 1,824 mm x 389 mm x 22 mm and a weight of 8 kg. It options an effectivity of 19%, an open-circuit voltage of 12.9 V, and a short-circuit present of 8.39 A.

Both photo voltaic tiles include a 10-year product guarantee and a 25-year energy output assure. They are fabricated with an IP65 enclosure and have an working temperature coefficient of -0.41% per C. The most system voltage for each merchandise is 600 V.

The Solar Roof system consists of normal PV panels fitted with Click-on expertise and aluminum composite panels (ACPs). “Its measurement is variable and is appropriate for residential initiatives, carports, and facades,” the corporate’s CEO stated, noting that the panels might be put in in both a panorama or portrait configuration.

“Right now, headquarters and manufacturing facility are based mostly in Viljandi, Estonia,” Silver famous. “As a producing firm, we emphasize automation, one of many fundamental areas the place we use the funding. Increasing manufacturing capability and robotizing strains will put together us for growing demand.”
