Flat Plate Solar Panels:
The Workhorse of Solar Heating
Flat Plate Solar Panels has earned the distinction as the workhorse of solar heating. This solar panel is the most used in the world.
Flat plate solar panels; also called solar collectors, are recognized as the workhorse for solar water heating and solar air heating systems.
A flat plate panel is a rectangular shaped box containing fluid tubes over a dark colored absorber.
Application:
They are proven technology for both residential and commercial applications including car washes and boiler systems. They are also used to heat air. You won’t be disappointed.
Flat Plate Solar Panel used for residential solar energy.
Climate Suitability:
These panels provide for dependable performance in almost any climate. However they are best suited for warm climates but are commonly found in cold climates. Freeze protection can be problematic.
Siting Consideration:
Flat plate panels can be mounted on the ground, on the roof or in the roof itself.
A complete site assessment where the you want to place the panels is critcal to the performance of the solar heating system. The assessment identifies site characterists that could cause the heating system to under-perform. Go to

When mounted on a roof they resemble a skylight by following the roof line. This feature improves the aesthetics dramatically.
How Flat Plate Panels Work
A flat plate panel is a rectangular box containing tubes mounted on a black absorber plate and covered with a glass or plastic glazing and even unglazed.
The Sun’s solar energy strikes the absorber plate which holds solar radiation inside the panel increasing its efficiency. For more information.
A flat plate solar panel consists of several distinctive features:
A water tight metal box,
The top a glazed with glass or plastic,
The bottom is a dark colored absorber plate.
A black absorber plate,
The sides and bottom are insulated to store heat.
A safety glass cover slows down heat loss and traps solar energy inside the panel. Swimming pool flat plate collectors do not have the safety plate glass cover.
Design Features:
The black absorber plate absorbs solar energy. In order to increase panel efficiency, absorbers usespecialized surface coatings.
This coating allows the conversion of a high percentage of solar radiation into heat. The coating also helps to retain the heat in the panel. At a minimum solar paints are used. These paints can capture a large amount of solar radiation but lose much of the heat.
More advanced coatings like galvanically black chrome, black nickel, aluminum oxide with nickel titanium-nitride-oxide Technologically advanced coatings retain more heat increasing the panel efficiency.
Performance:
The flat plate solar collector heats water to be 86 - 158°F (30-70°C).
Manufacturers:
The Solar Rating and Certification Corporation (SRCC) is an independent third-party certification organization that administers national certification and rating programs for solar energy equipment.
The SRCC certifices solar heating systems based on test methods that must meet minimum standards. The tests are conducted by independent laboratories accredited by SRCC.
The SRCC certification lable gives you the assurance that the solar heating system you purchase will perform adequately.
The SRCC certification is a requirement to receive
federal tax credits and incentives.
Many state and utility programs also require SRCC certificaion.
