Technology with the photovoltaic glass curtain wall

Italian manufacturer Solarday has launched a glass-glass building integrated monocrystalline PERC panel, available in red, green, gold and gray.Its power conversion efficiency is 17.98%, and its temperature coefficient is -0.39%/degree Celsius.
Solarday, an Italian solar module manufacturer, has launched a glass-glass building integrated photovoltaic panel with a power conversion efficiency of 17.98%.
"The module is available in different colors, from brick red to green, gold and gray, and is currently being produced at our 200 MW plant in Nozze di Vestone, in the province of Brescia in northern Italy," a company spokesperson told pv magazine.
The new single crystal PERC module is available in three versions with nominal powers of 290, 300 and 350 W.The largest product uses a 72-core design, measures 979 x 1,002 x 40 mm, and weighs 22 kg.The other two products are designed with 60 cores and are smaller in size, weighing 20 and 19 kg respectively.
All modules can operate at a system voltage of 1,500 V, with a power temperature coefficient of -0.39%/degree Celsius.Open circuit voltage is 39.96~47.95V, short circuit current is 9.40~9.46A, 25-year performance guarantee and 20-year product warranty are provided.The thickness of the front glass is 3.2 mm and the operating temperature range is – 40 to 85 degrees Celsius.
"We are currently using solar cells from M2 to M10 and different numbers of busbars," the spokesperson continued.The company's initial goal was to color solar cells directly, but later chose to color glass."So far, it's cheaper, and with this solution, customers can choose between different RAL colors to achieve the required integration."
Compared with traditional modules for roof installation, the price of new products provided by Solarday can reach up to 40%."But BIPV needs to be understood as the cost of changing traditional building materials for custom photovoltaic curtain walls or color photovoltaic modules," the spokesperson added."If we consider that BIPV can save the cost of classic building materials and add power generation advantages with high-quality aesthetics, then this is not expensive."
The company's main customers are photovoltaic product distributors who want to own EU-made products or color modules."Scandinavian countries, Germany and Switzerland are increasingly demanding color panels," he said."There are many local regulations that will integrate photovoltaic power generation in historic districts and old towns."
