Photovoltaic solar panel - Midsummer WAVE

Midsummer WAVE is a black, wave shaped solar panel that is specifically designed to fit on roofs with two-barrel roof tiles.

WAVE is a CIGS photovoltaic solar module. CIGS stand for Copper-Indium-Gallium-Selenium, a tetrahedrally bonded semiconductor, with chalcopyrite crystal structure that converts the energy of light directly into electricity by the photovoltaic (PV) effect. The CIGS absorber and all other materials that form the finished solar cell are deposited on a stainless-steel substrate. The cells are then connected in series via a front contact grid, which is screen printed, using a power mesh technology. This consists of a dense array of wires for current collection instead of the regular ribbons, which reduces the resistive losses and increases the active area.

CIGS solar cells are manufactured by sputtering the material onto 156×156 mm stainless steel substrates. The solar cells from Midsummer are free of cadmium, a toxic material usually used in CIGS and other thin film solar cells. Flexible CIGS solar modules are gaining increasing market share thanks to its high efficiency, low weight, flexibility and durability.
