Solar Water flat collector

An example of solar water heating at its most basic level is a garden hose left out in the sun. When you turn on the spigot, the first water to come out of the hose is warm since its been baking in the sunlight. A solar water collector works in a similar fashion. Water flows through tubes housed in a solar collector. Throughout the day, a sensor monitors the difference in water temperature between the water in the storage tank (inside the home) and the water in the collector (typically mounted on the roof). At a preset temperature difference, the sensor triggers a pump to circulate the water through the collectors where it absorbs solar heat. In summer months, a solar hot water system can meet all your household hot water needs! Over the course of the year, the system can cover up to 85% of your hot water needs. The typical investment is about $3,000 to $6,000, not including installation. Be sure to investigate in your area which can help reduce that initial investment.

1)Solar collector uses high absorption coating, flat collector.
2)better adhesion resistance to corrosion, and low heat yield.
