The materials used for building our panels offer a guarantee of strength and durability against inclement weather, difficult to achieve with other systems. Honeycombed Polycarbonate is of Italian origin, UV resistant and its resistance to sun exposure and impact are excellent. The high density 3 resins polyethylene tubes are completely harmless and makes them invulnerable against any chemical and UV rays. Life expectancy is 30 years subjected to high temperatures. The structure is made of galvanized sheet iron or aluminum.These panels allow virtually any type of water without caring about its salt content, impurities or chemicals dissolved. Panels do not allow water with suspended elements therefore water should be filtered or treated. Applications have been implemented to heat swimming pools, industrial water, heating systems and sanitary hot water, interconnecting systems with different uses and the same set of solar panels.
