The cost is a bit annoying and the technology is 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 + working fluid Freon + motor thermic + generator (the configuration of a solar power plant cannot be carried out by individuals)
Your height difference can be obtained by filling the 75 mm diameter pipe with a power of 2 kW. If your 10 cm pipe is not already installed.
If the performance is good, it is recommended to use “double-tube double-jet oblique impact hydroelectric generator”. This is a second generation machine with a price of around 6,000 yuan.
Solve the lighting problem If it is one type, just use the old one "slope type". This is the first generation product. Its performance is not that good, but it is cheap and can be had for around 1500.
