How to install photovoltaic solar panels: 1. Before installation, you must first know the positive and negative poles of photovoltaic panels and connect them in series. Do not make a mistake, otherwise it will cause charging failure, in severe cases, the battery board will be burned out, the service life will be greatly shortened, and there may even be a risk of explosion. 2. Next you need to arrange the wires. Try to choose insulated copper wires and the colors should be different, in order to facilitate installation. Install the wires in place and wrap the joints with electrical tape.
3. Then determine the direction in which the photovoltaic solar panels should be installed. The best direction is south to meet lighting requirements. Finally, adjust the tilt angle. If it is close to south, the angle can be set smaller. For example, if the latitude is included inBetween 0 and 25 degrees, the elevation angle can be adjusted to approximately 25 degrees. If the latitude reaches between 26 and 40 degrees, add 5 or 10 degrees to the 25 degrees.
Solar energy is a renewable energy source. It refers to the radiant thermal energy of the sun (see the three modes of propagation of thermal energy: radiation), and its main manifestation is often called solar rays. Nowadays, it is typically used to generate electricity or provide energy for water heaters.
Advantages of solar energy
(1) Universal: The sun shines all over the earth and has no geographical restrictions. It can be found everywhere, whether on land or in the sea. on mountains or islands, and can be directly developed and used, easy to collect, and does not require mining or transportation.
(2) Harmless: the development and use of solar energy will not pollutet not the environment. It is one of the cleanest sources of energy, which is extremely valuable today as environmental pollution becomes more and more serious.
(3) Huge: The energy of solar radiation that reaches the Earth's surface each year is approximately equivalent to 130,000 billion tons of coal, and its total amount constitutes the greatest energy that can be developed in the world today.
(4) Long term: Based on estimates of the rate of nuclear energy produced by the sun, hydrogen storage is sufficient to last tens of billions of years, and the duration life of the Earth is also about billions of years. In this sense, we can say that the energy of the sun is inexhaustible.
Disadvantages of solar energy
Instability: Due to the limitations of natural conditions such as day and night, season, geographic latitude and altitude, as wellthan the influence of random factors such as sunny, cloudy, cloudy and rainy. Therefore, solar irradiation reaching a certain ground is both intermittent and extremely unstable, making large-scale application of solar energy more difficult. In order to make solar energy a continuous and stable energy source and ultimately become an alternative energy source that can compete with conventional energy sources, the problem of energy storage must be well solved , that is, the energy of solar radiation during clear days should be stored as much as possible for use at night or when it rains. It is used for everyday use, but energy storage is also one of the weakest links in solar energy use.
Low efficiency and high cost: At the current level of development of solar energy use, some aspects are ttheoretically feasible and technically mature. However, some solar energy utilization devices have low efficiency and high cost, and the current laboratory use efficiency does not exceed 30%. In general, the economy cannot compete with conventional energy. for some time, the development of solar energy use was mainly limited by economic reasons.
Photovoltaic panel installation process:
1 Site selection
The sun must be able to shine all day 'year. (For example, on the roof of a building).
2. Making the foundation
After determining the azimuth angle according to the geographical location, combine the shape of the photovoltaic module support to make the support foundation (such as a concrete base). .
3. Install the bracket
Install and attach the bracket to the fundulation, and adjust the azimuth and elevation angles.
4. Install the photovoltaic modules
Install and fix the silicon crystal solar panels to the support according to the pre-designed plan.
5. Electrical connection
Firstly, the electrical grounding of the bracket and photovoltaic modules should be carried out, and then the wiring of each silicon crystal solar panel should be connected according to the design.
6. Electrical debugging
After the silicon crystal solar panel wiring is connected and checked, connect the inverter, battery and other equipment for common debugging.
Precautions for installing photovoltaic solar panels
1. Do not install photovoltaic solar panels in shady places such as trees and buildings. Do not approach open flames or flammable materials. The assembly structure must be able to adapt to theenvironmental requirements. Please choose appropriate materials and anti-corrosion treatments. Use reliable methods to install components. If components fall from a high altitude, they may cause damage or jeopardize the safety of people and property. Do not disassemble, bend or hit components with hard objects. Avoid walking on components.
2. Use spring washers and flat washers to secure the photovoltaic solar panels to the bracket. Ground the panel assembly appropriately based on the site environment and the structural condition of the mounting bracket.
