Solar panel efficiency or conversion rate refers to how much electrical energy is converted into solar energy. Affected by many factors, the actual amount of solar power generated is not as much as estimated. Before installing solar panels, the installer should consider the factors that affect the solar panel's power generation rate as much as possible, and how to better realize the value of solar panels. So what are the factors that affect solar power generation?
1. Spacing and orientation of solar panels
If the PV system installed in the northern hemisphere should face south, if the solar panels are installed above the roof, the spacing of the roof should be considered. In order to maximize the effectiveness of solar panels, the orientation of solar panels should be adjusted twice a year. In the summer, when the sun is shining, you can get more light by tilting the solar panels. In winter, there is not enough light. The sun is slanting on the ground. The solar panels need to be adjusted in the past few months. As for the mobile solar light tower, make sure each time for deployment, the panels are unfolded towards the sun.
The amount of electricity generated by solar panels will change with the influence of temperature。 If high temperature occurs, the power production of solar panels can be seriously reduced。 A higher temperature causes the conductivity of the semiconductor to increase, and the charge becomes more stable in the material, thereby reducing the magnitude of the electric field, suppressing the separation of charges, and causing the voltage across the battery to be lowered。 Its heat can reduce the output power by 10% to 25%。 How to solve the high temperature problem? Installing solar panels on a mounting system a few inches from the roof helps to cool them by air circulation。 The panels are made of light-colored materials to reduce heat absorption。 The inverter and combiner can be moved to the shaded area behind the array。
极品斗地主3, the shade
The shade is definitely a natural enemy of solar panels。 If a small portion of the solar panel is blocked, it can sometimes cause solar energy on all other panels to stop working。 The solar cells on the solar panel are connected in series and remain in normal operation at the current level of the weakest battery。 If some of the cells on the solar panel are blocked, it will affect the normal output of other batteries。 Before determining the position of the solar panel, analyze the surrounding environment to avoid obscuring the solar panel during peak hours。
4, surface pollution
Solar panels will become dirty due to prolonged use, covering dust, fallen leaves, and bird droppings, which will block solar panels and affect their absorption of light energy. Therefore, solar panels should be inspected regularly. When cleaning, it should be wiped with a soft damp cloth during the day or night when the light is not strong to ensure the cleanness of the solar panel, which can effectively absorb the solar light energy.
