Solar Panels Parts
solar panels?
Does anyone know why solar panels for heating cost so much. They have no moving parts. They just get hot.
I mean the kind that are used for heating water and then pumped into the house.
I am new to this so if I am doing this wrong, please accept my appology.
donfletcheryh, are you telling me that you are using a system with 404 in it instead of water to move the energy? If that is the case, do you not still use much electricity to run the compressor.
I used a Killawatt meter on a refrigerator and found it used 150 in electricity a year. Convection of a panel, should be basically zero electricity right? The hot water rising is piped to use, and cooler water then flows up into the panel?
You can make your own. Materials are cheap and readily available. One caution. the sun’s heat in a flat panel can raise temperatures high enough to cause deterioration of wood, so significant that if dry and used for a few years, they can set fire to the wood. They need to be mounted on stands that lose heat before contact with wood or asphalt shingles.
Systems of water heating panels have to be protected from freezing or drained. They can be filled with antifreeze, but then we have to be very careful to avoid mixing with domestic water.
Systems have to be designed to deliver heat, and avoid dissipating that heat by circulating when there is no sunlight, or when panel heat is less than that in storage.
We can have a refrigeration line going across the top of banks of flat panel collectors, such that the refrigerator sealed unit removes heat from the panel to deliver it to either a water storage or to inside air. This means we have no freezing problem, no antifreeze to poison us.
But people who have learned how to make reliable flat panel collectors like to make some money. The information is readily available for anyone able to read and understand, with none of that mark up.
