Best solar installation system – best solar installation angle

“< H2 > my family is going to install a solar power generation system. Do you need to pay attention to anything? Please explain

What details should solar power generation system pay attention to

Many people have heard of solar power generation system, but they know very little about the basic knowledge of power generation system application. Here are the details of solar power generation system:

1. Photovoltaic cells are high resistance current sources and batteries are low resistance voltage sources. So we can short circuit the components, but we must not short circuit the battery

2. When the solar module is covered, it becomes an objective large resistance. If it is not drained, it will heat quickly

3. The 25 ℃ defined by solar module is the working temperature of the module rather than the ambient temperature

4. Solar modules with the same size materials (single crystal / polycrystalline) and the same rated power are deceptive if they are marked with different conversion efficiency

5. The wage voltage at the maximum power point of the solar module and the open circuit voltage of the module are a constant relationship of 0.8, which is very close. It is very important and convenient to estimate the rationality of inverter and system structure

6. For the current solar modules, the system is connected in parallel with more than 3 strings, and there must be overcurrent fuse protection

7. The influence of floating ash or even distribution on the surface of solar modules on efficiency is generally less than 5%

8. There is no sun or drizzle on cloudy days, the output power of the system is very small, and the open circuit voltage and working voltage of solar modules are very high

9. If the number of components of the East-West oriented system is the same, it can be connected in parallel without serious voltage dislocation

Is it suitable for home users to install solar power generation system

In fact, most of the reasons for the recent national promotion of distributed power generation are to promote the installation of distributed power generation in households

Of course, families can install photovoltaic power generation. However, the installation environment of most families is not ideal, so the return on investment is low compared with that of factories. Not so attractive

There are many personal installations abroad (Germany, the United States, etc.), mainly due to the good installation environment, good investment return and easy procedures. Ha ha

The state subsidy of 0.42 is true

Thank you. It seems that it can be installed. The main purpose of installing this is to do a small public welfare. Ha ha

How to install the auxiliary electric heating system in the solar water heating system

The solar water heater heats water by solar radiation, but the heat output of the solar water heater is insufficient in rainy days or winter without the sun. In order to be used 24 hours a day, an auxiliary heating system must be added. Auxiliary heating systems include oil heating, electric heating, natural gas or liquefied gas heating and boiler coal heating. No matter what kind of auxiliary heating system is adopted, solar energy should be used as the main heat source for optimal design. The auxiliary electric heating system consists of two parts. One part is the electric heating tube, which is a component that converts electric energy into heat energy; The other part is the control system, which can be divided into automatic control, manual control and semi-automatic control according to different control modes. There are two ways of electric heating: one is that the electric heating device is installed in the bathroom; In the Taisheng room, it is set separately from the solar water storage tank; The other is to insert the electric heating pipe into the middle and lower part of the water tank to heat the water above the electric heating pipe. With the I system equipped with auxiliary electric heating, in the case of insufficient solar irradiation in cloudy and rainy days, the water temperature in the solar hot water tank will also rise, but it can not meet the shower requirements. At this time, as long as the is heat is supplemented by electric heating to raise its temperature a little, it can meet the shower water temperature requirements, so as to achieve the purpose of all-weather use

The company is willing to promote the application of green energy with high-quality products and perfect services, and create a better tomorrow for human development! When designing a solar power generation system, you should first know the power of your electric equipment, input voltage, daily working hours of the equipment, installation area and the number of rainy days. With these parameters, the configuration of solar system can be designed

Installation generally determines the tilt angle of the solar panel according to your local latitude, with the direction facing south. Determine whether the battery is buried according to the local ambient temperature. My Taobao store (outstanding new energy) has technical indicators and prices of solar energy products and equipment for reference. First, investigate the local weather data such as sunshine time, intensity, temperature, sunny and cloudy days (very important). Secondly, determine the daily power consumption of the electrical appliances to be supplied, and further determine the specific parameters of your photovoltaic system according to these two aspects of information, such as how many solar panels, how large controllers, how large inverters, how much storage batteries, etc. The next step is installation and debugging

The design and installation of solar photovoltaic power generation system is a complex and systematic work. It’s only superficial for you, and you need to study it more carefully

I hope you will design and install your own solar photovoltaic system as soon as possible
