1.How long does it take to recover the cost of the investment in home solar power system?
The installed capacity of the general solar power system is about 3-10 kW. According to the different sun lighting conditions, user side electricity price, subsidies, and system costs, the cost can be recovered in about 6 years, and the life of the solar power system can reach 25 years. That is to say, the electricity revenue and electricity charges saved in the remaining 20 years will become direct profits.
2.If the power grid is cut off, can the solar power system still work?
With the sun during the day, the solar power system can generate electricity, and it doesn’t matter if the power grid is cut off. You can’t use it without the sun at night unless you have a battery.
3.Is there a shortage of electricity in cold winter?
The direct impact on power generation is the irradiation intensity, sunshine duration, and the working temperature of solar panels. In winter, the radiation intensity will be weak, the sunshine time will be short, and the power generation will be less than that in summer. Home solar power system is generally connected to the grid, as long as the grid has electricity, there will be no power shortage and power failure.
4.How to clean solar panels?
Rainwater can be cleaned without special maintenance. If there is any attached dirt, simply wipe it. In order to avoid electric shock injury and possible damage to the solar panel caused by wiping the solar panel under high temperature and strong light, it is recommended to clean the solar panel in the morning or late afternoon. Solar panels have a certain load-bearing, but can not step on the top of the solar panel when cleaning, it will cause hidden damage to the solar panel, affecting the life of the solar panel.
5.Will house shadows, leaves, and dust affect the solar power system?
It will affect power generation. If the leaves and bird droppings are found, they need to be cleaned up in time.
6.Can it resist typhoons and hail?
Solar power system is designed according to the local conditions, wind pressure, accumulation, roof style will be considered, can achieve a certain level of wind resistance, hail resistance.
7.When the temperature is very high, can the parts be replaced immediately if they are broken?
It can not be replaced immediately. It is recommended to replace it in the morning or later in the afternoon, and we suggest you contact the operation and maintenance personnel of the power station in time and replace it with professional personnel.
8.Is it necessary to disconnect the solar power system in thunderstorm weather?
Home solar power systems are equipped with lightning protection devices, so there is no need to disconnect. In order to ensure safety, it is suggested to disconnect the circuit breaker switch of the combiner box and cut off the circuit connection with the solar panel, so as to avoid the harm of direct lightning that cannot be removed from the lightning protection module. The operation and maintenance personnel should timely detect the performance of the lightning protection module, so as to avoid the harm caused by the failure of the lightning protection module.
9.Do solar panels radiate?
Solar power system is to convert solar energy into electric energy, no pollution, no radiation, no harm to human body.
10.How about the power generation effect in rainy weather?
It can also generate electricity on rainy days, but the effect is not very good. If it is cloudy, the power generation is only about 20% of that of sunny days.
11.If we add a solar tracker (automatically adjusts the angle and direction of the solar panel), will it generate more power?
More power can be generated, but the cost is not directly proportional to the amount of power generated, and the cost recovery period should be increased. In addition, the tracker is mechanical equipment, the reliability is not high, which will increase the cost.
12.Are there any restrictions? Is it difficult to install by myself?
There are no restrictions on the installation of home solar power system, so you need to fill in the application form in the power grid business hall. Installation requires professional knowledge. It is recommended to find a professional solar panel manufacturer or installer for installation. If the power grid has equipment qualification requirements, individuals may not be able to get it.
