How can you compute for the heat transfer of a solar panel thru radiation and convection?lets assume that the sun will give an ideal energy and what will also happen I will or will not use a heat exchanger? can someone explain me how and give me a formula for the computation
First decide what you % to realize. Is it (a) to shop money or (b) to shop the planet? If that is (a) in Britain, you may frequently overlook approximately it. The exception could be for swimmimng swimming pools using fact the warmth is critical interior the summertime whilst the equipment is maximum efficient. If that is (b), then you definately've 2 person-friendly structures to think approximately. the finest (and maximum inexpensive) technologies is composed of water crammed creditors that only warmth up by potential of distinctive function of the radiant results of the sunlight. the nice and cozy water may be used to warmth your warm water. no count if it somewhat is built-in with a prevalent heating equipment, you're able to take precautions to keep away from the collector turning out to be a extensive radiator in wintry climate and as a result dropping warmth enormous time! on the different hand, you ought to look at photovoltaic (PV) structures that generate electrical energy. those value very severe money and you at the instant are not likely to generate adequate electrical energy for all your desires so it does no longer replace your mains connection, in basic terms decrease your dependence. regrettably, in this usa, electrical energy companies at the instant are not compelled to purchase electrical energy from the likes of you and me on the cost they sell it as in some greater enlightened international locations, so the economics at the instant are not encouraging. the two those structures artwork optimally with a extensive expanse of south dealing with roof to attach them to, nevertheless they're going to artwork on different orientations, if much less effectively. provides are attainable by potential of employing the Low Carbon homes programme yet they simply hide a small share of the cost. little need for DIY nevertheless as you ought to use authorized installers.
The term solar panel usually refers to photo-Voltaic cells which convert radiant energy into electricity. Convection is unrelated to this process. Heat exchangers are used in solar collectors which convert radiant energy into heat. The two systems are completely different. Assuming you wish to convert radiant energy into heat, the first step is to determine the insolation (average solar energy available at your location based on lattitude, longitude, season, climate, and other factors. This data is available from several sources). Next you will need to determine the conversion efficiency of your collector, as well as its insulation ratings, and ability to track the the suns transit. The calculations required are specific to the technology used. See the reference below as a starting point.
