Solar panels are electronic components, and the technology and processes require expensive electronic production equipment to manufacture them. It is impossible to make them yourself, but you can cut them yourself with a combination of solar equipment. 2009-03-12 11:42:21 Supplement: See Dr. He. 2009-03-12 11:47:13 Supplement: The above editing error is not included, please add it again: See Dr. He's answer In one sentence, I thought my knowledge was limited and I was wrong. Then I saw it again... It turned out to be... haha.
You can make your own solar panels, but the products are expensive and expensive to sell on the street. You must first invest in a solar panel manufacturing factory. But there is one thing you need to know first. The return on cost is very slow because you are selling it at a very low price.
Small solar water heater fDIY
The cost is a bit boring and the technology is also difficult. It is recommended to purchase solar panels + batteries + inverters to do so.
You can only generate photothermal energy by yourself. Paint an aluminum plate black, press the thermoelectric power generating part below and below the thermoelectric power. The generating part is an aluminum plate, and dip the aluminum plate underneath into water. But the electricity produced is pitiful.
2. Use hot water from solar water heater + thermoelectric film: make a heat exchanger, use hot water to heat the upper plate, and use cold water to cool the lower plate if there is a temperature. difference on both sides of the thermoelectric film, electricity will be generated.
3. Use heat pipes + thermometers
4. Heat pipes + fluworking idea Freon + heat engine + generator (the configuration of a solar power plant cannot be carried out by individuals)
Take a wooden box similar to a drawer, put a foam board of 4 5 cm thick (or an old quilt) on the bottom and around, and cover the wooden box with a piece of glass (or plastic sheeting).
Put 1-2 inside, with a diameter of 15-20 cm and a height of 60-100 cm. It is a container filled with water made of galvanized sheets. The exterior of the container is painted black. and there is a hole at the bottom for water inlet, there is a water outlet at the top, which is connected to the hot water faucet in the house. There is an overflow port at the top for when the water is full and overflows. , close the water inlet tap.
Such a simple solar water heater is made. Water temperatures can reach 60 degrees in summer and 45 degrees in winter.
