Since 2004 we manufacture solar thermal water heater panels. The materials used for building our panels offer a guarantee of strength and durability against inclement weather, difficult to achieve with other systems. Insted of glass we use honeycombed Polycarbonate, UV resistant and its resistance to sun exposure and impact are excellent. Water circulates through high density 3 resins polyethylene tubes, 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.
