The installation process of photovoltaic power generation is as follows: 1. Before installation, it is first necessary to figure out the positive and negative poles of photovoltaic panels, and to connect them in series. Don't make a mistake, otherwise it will lead to no charging, and in serious cases, it will burn out the battery panel, the service life will be greatly shortened, and there will even be a danger of **.
2. Next, you need to arrange the wires, try to choose the insulating copper wires, and the color is best different, so that it can be conducive to installation. Install the wires in place, and wrap the joints with insulating tape. 3. Then determine the direction of solar photovoltaic panel installation, and the direction is preferably due south to meet the requirements of light.
Hello! Dear, glad to answer for you! The photovoltaic power generation installation process is as follows:
1. Before installation, it is first necessary to find out the positive and negative electrodes of the photovoltaic forest carrying the board, and to connect them in series. This hand must not be mistaken, otherwise it will lead to no charge, and in serious cases, it will burn out the battery board, the service life will be greatly shortened, and there will even be a danger of **. 2. Next, you need to arrange the wires, try to choose the insulating copper wires, and the color is best different, so that it can be conducive to installation.
Install the wires in place, and wrap the joints with insulating tape. 3. Then determine the direction of solar photovoltaic panel installation, and the direction is preferably due south to meet the requirements of light.
4. Finally, adjust the angle of inclination, if it is close to the south, the angle can be set smaller. For example, if the latitude is between 0 and 25 degrees, the elevation angle can be set at about 25 degrees. If the latitude reaches a macro and the width of the stool is between 26 and 40 degrees, add 5 or 10 degrees to the 25 degrees.

Before installation, it is first necessary to find out the positive and negative poles of the photovoltaic panels, and to connect them in series. Don't make a mistake, otherwise it will lead to failure to charge, and in serious cases, it will burn out the battery panel, greatly shorten the service life, and even appear to be in danger.
2. Next, you need to arrange the wires, try to choose the copper wires with insulating nanopunch, and the color should be different, so as to facilitate the installation. Install the wires in place, and the joints need to be wrapped with insulating tape into the slag row. 3. Then determine the direction of solar photovoltaic panel installation, and the direction to which it is best to be due south can meet the requirements of light in the morning.
Finally, adjust the angle of inclination, if you are closer to the south, the angle can be set smaller. For example, if the latitude is between 0 and 25 degrees, the elevation angle can be set at about 25 degrees. If the latitude reaches between 26 and 40 degrees, add 5 or 10 degrees to 25 degrees.

The photovoltaic installation wiring method is as follows: the photovoltaic solar power generation system is composed of a solar cell group, a solar controller, and a battery (group). If the output power supply is AC 220V or 110V, an inverter is also required.
The positive pole of the output line of the photovoltaic solar panel is connected to the positive pole of the distribution board, and the negative pole is connected to the negative pole. The simplest thing is to connect a diode in series.
Hello! Kiss! The wiring method of photovoltaic installation is as follows:

If the output power supply is 220V or 110V, an inverter is also required. The positive pole of the output line of the photovoltaic dust lead solar power generation board is connected to the positive pole of the distribution board, and the negative electrode is connected to the negative pole.
The simplest thing is to connect a diode in series.
The functions of each part are as follows: (1) Photovoltaic solar Jianhui energy panel: Solar panel is the core part of the solar power generation system of Tai or Gai Ting, and it is also the most valuable part of the solar power generation system.
Its function is to convert the sun's radiation ability into hidden electrical energy, or send it to the battery for storage, or push the load to work. The quality and cost of solar panels will directly determine the quality and cost of the entire system; (2) Photovoltaic solar controller: The function of the solar controller is to control the working state of the whole system, and play the role of overcharge protection and overdischarge protection for the battery.
In places with large temperature differences, qualified controllers should also have the function of temperature compensation. Other additional functions such as light switch and time switch should be optional for the controller;

Then determine the direction of the solar PV panel installation, preferably due south, to meet the requirements of the light: finally adjust the angle of inclination.
Before installation, you first need to figure out the positive and negative poles of the photovoltaic panels, and then you need to connect them in series with the slip plexus: then you need to arrange the wires and install the wires in place: and then determine the direction of the solar photovoltaic panels to be installed in the direction of the south, so as to meet the requirements of the light
Finally, adjust the angle of the tilt.
Does the installation of photovoltaics require aerial work?
If it's a home solar installation, you don't need a work-at-height license.
According to the relevant regulations of the state, high-altitude work refers to the operation of more than 2 meters (including 2 meters) from the datum, and even if the spike is installed on the roof of the building, the hidden group will not exceed 2 meters relative to the datum of the roof!
If it is a photovoltaic installation of the project, it is also necessary according to the height.
Is the outlook for the PV industry good now?
For photovoltaic companies, of course, it is the pursuit of profits; At present, most of China's photovoltaic products are exported, which does not contribute much to China's own energy structure. >>>More
All I know about PV inverters is this.
Different light power is different, different working voltage power is different, different power charging conversion efficiency is different, photovoltaic modules have different power after a period of time, photovoltaic modules of different materials have different power for a long time, and the power is different when there is more dust in the use area.
The areas included in the first category of resource areas are as follows: >>>More
The first thing to do is to determine whether it is on-grid or off-grid. In addition to the configuration of the inverter, it should be determined according to the technical indicators of the entire photovoltaic power generation system and refer to the product sample manual provided by the manufacturer. Generally, the following technical indicators should be considered. >>>More
