For the hot water collection tank, a aluminium sign board is required. Even if power is used to pump water into the system, the cost is recovered through increased energy savings, since the indoor tank is weatherproof and has better insulated hot water. The advantage of an active system is that it is possible to place the tank in the best position, so that hot water is readily available. In addition, there is usually an integrated frost protection, where under cold conditions hot water is pumped into the collectors to prevent frost and cracking. The only disadvantage of active solar water heaters is their cost. A variety of coatings can be placed on a aluminium sign board for water that determines water efficiency and panel time: Black paint: This is the lowest grade coating. Although it is very cheap, it takes a lot of direct sunlight and strong to heat the water. It is good to use in warm and sunny climates, but generate enough aluminium sign board in cold and temperate regions.
