The heat conservation power consumption of solar water heaters is slightly lower than that of ordinary electric water heaters. This is also directly related to the intensity of the sun. For example, during the day there is practically no energy consumption, but. at night there is no sun. Now the insulation system has officially started working. I have received similar complaints before, saying that this solar water heater costs more than 100 yuan per month in electricity bills. It is therefore recommended to do it when there is no sun. in use, it is always necessary to use the isolation function. When the time comes, just warm up in advance. The money you save is RMB.
In the state of heat preservation, there is a program setting. Under a certain drop in temperature, the circuit is not powered, so it consumes very little energy when the temperature drops.ture goes down to the defined lower limit. sensor, etc. The circuit is open for electric heating. After reaching the set maximum value, the power supply is stopped. A 200 liter solar water heater consumes at least 2.5 degrees of electricity per day of heat conservation.
My house is equipped with air conditioning. Do you think it is necessary to install underfloor heating in winter in Hangzhou?
Solar panels (also called solar cell modules) are an assembly of several solar cells. They are the core part of the solar power generation system and the most important part of the solar power generation system.
Principle of energy production
Sunlight shines on the p-n junction of the semiconductor to form new hole-electron pairs. Under the action of the electric field of the p-n junction, the holes flow from the p region towards. the region n. Electrons flow from region n to region p and a current forms once the circuit is connected. This is how photovoltaic solar cells work.
Solar power generation methods There are two solar power generation methods: one is the light-heat-electricity conversion method and the other is the light-direct conversion method. electricity.
(1) The light-heat-electricity conversion method uses thermal energy generated by solar radiation to produce electricity. Generally, a solar collector converts the absorbed thermal energy into steam as the working fluid and then drives it away. a steam turbine to produce electricity. The first process is a process of converting light into heat; the second process is a process of converting heat into electricity.
(2) The method of directly converting light into electricity usesthe photoelectric effect to directly convert solar radiation energy into electrical energy. The basic device for converting light into electricity is the solar cell.
A solar cell is a device that directly converts solar energy into electrical energy through the photovoltaic effect. When the sun shines on the photodiode, the photodiode converts solar energy into electricity. . Light energy is transformed into electrical energy, creating an electric current. When many batteries are connected in series or parallel, a solar cell array with relatively large output power can be formed.
Detailed information
Lifespan
The lifespan of solar panels is determined by the quality of the cells, glass tempered, EVA, TPT, etc. Determined by the material, manufacturers who generally use better materials have littlewind produce panels with a lifespan of up to 25 years. However, with the impact of the environment, solar panel materials will age over time. Under normal circumstances, the electricity is used for 20 years, it will decrease by 30%, and the power will decrease by 70% after 25 years of use.
Inspection and maintenance
1. Check whether the battery board is damaged, find out in time, and replace it in time.
2. Check whether the battery board connection wire and ground wire are in good contact and whether they fall off.
3. Check for heat at the mixer box junction.
4. Check if the battery panel bracket is loose or broken.
5. Check and clear weeds around the battery panels that are blocking them.
6. Check if there is a cover on the surface of the battery panel.
7. Check for bird droppings on the surface of the panbattery ring and clean them if necessary.
8. Evaluate the cleanliness of the battery panels.
9. In windy weather, key inspections of panels and battery holders should be carried out.
10. On heavy snow days, the battery panels should be cleaned in time to avoid the accumulation of snow and ice on the surface of the battery panels.
11. In case of heavy rain, check whether all seals are in good condition and whether there are water leaks.
12. Check to see if animals have entered the power plant and damaged the panels.
13. In the event of hail, key inspections should be carried out on the surface of the battery panels.
14. Detect the battery panel temperature and compare it with the ambient temperature for analysis.
15. Detected issues should be addressed, analyzed and summarized in a timely manner.
16. Keep recordsDetailed ts of each inspection to facilitate future analyses.
17. Carry out analyses, summary reports and archive them.

If your indoor space is about 100 square meters, using air conditioning for heating in winter is very expensive and may cause discomfort to human body. In recent years, the climate has changed and the demand for heating in the south has also increased. Heteropolymer waterless solar heating is the healthiest and safest heating method. The heating cost per month is around 403 and the indoor temperature is between 17. -22°. If you have any questions, send me a private message
