On-Sun Systems

On-Sun Systems is commercialising a disruptive solar concentrator photovoltaic (CPV) technology. Our solar panels are ideally suited to commercial and residential rooftop applications due to their superior efficiencies and energy density. Based on the principal of focusing sunlight onto highly efficient multi-junction PV cells, On-Sun’s patented technology enables solar installations to generate substantially more energy per site. To the installer, our panels are flat, fixed, stationary devices – just like standard crystalline silicon panels. However, internal to our panel we track the sun to maintain an optical concentration ratio of over 500 times. As with all CPV applications, On-Sun’s panels are ideally suited for installations within the Solar Belt. This includes (but is not limited to) the major markets of southern Europe, South West USA, India and China. On-Sun Systems has a finance office in the UK near Ledbury and a product development centre in Barcelona, Spain.
