Resulting from 25 years of Italian PV Technology the H series Monocrystalline modules offer one of the highest power density ratios available. The first H series production started in 1981 by those who believed and stuck to the vision while most were not interested???.. when solar energy was not the fancy business it has become today. Ranging 12??150 W, the Current output is 10-17 % higher than typical modules output at operating battery voltage. Sold over Europe, Africa and Middle East for years and recently in Australia they proved their value in the field, supplying reliable free electricity to remote schools, hospitals, farms and missions quietly over the years. Perfectly suited to battery charging applications/stand-alone systems such as rural electrification, lighting, telecommunications and water pumping. 25 year warranty
