It is not necessary to refill the water every day, as long as the water tank has no water for a long time and causes empty drying. Fill the water once and continue to use it until the water in the water tank is used up and the top is filled with water.
I don't know if refilling the water every day will breed bacteria. This question has not been studied. The weather is sunny now, so use half the water from the water tank and refill it. If you fill the water tank in the morning, the temperature will reach over 90 degrees at night. Water at 100 degrees should be considered boiling water!
I hope this can help you, haha.
The first 0.5 kW solar panel generates five kilowatt hours of electricity per hour. 5 kW times 1 hour = 5 kilowatts per hour = 5 kilowatt hours of electricity.
The specific amount of electricity. generated per day depends on youre purchase. The quality of photovoltaic modules is determined by a series of specific factors such as the duration of winter sunshine in the province in which you are located and the elevation angle of the installation.
Second. A roof of 100 square meters (in theory, based on 8 hours of sunshine per day, it is generally considered 6 hours of effective sunshine. )
100 square meters can install a photovoltaic system 6 to 10 kW (it will vary depending on the shape and layout of the installation, and the specific situation should be determined according to the actual situation). If calculated based on 5 kW, 20 250 W photovoltaic modules, 1 5 kW inverter, 1 set of brackets, several cables, 1 circuit breaker and 1 distribution box are required. The total amount of system equipment is about 30,000 yuan (the specific situation may be higher).
5 kW generates about0.5 million kilowatt hours per year. Under normal circumstances, they do not require much maintenance, that is, they generate around 0.5 million kilowatt hours per year. clean the surface of the components and check the working conditions, but the electronic equipment (mainly the inverter) may still need to be replaced. It depends on the specific conditions of the equipment. This shouldn't be a big problem if the PV modules operate for 25 years, but it's hard to say how long other equipment will last over that time.
I remember that the current price of components is between 4.5 and 4.1 yuan per watt.
