Why maintain solar panels?
I believe you already know that there are many factors affecting the power generation efficiency of solar panels, one of which is the stains, dust and sundries on the surface of solar panels
So when you find that the solar panels on your RV have only been used for a year or two, but the power generation efficiency is far lower than that at the beginning, I think you should get on the roof and care about the solar panels you installed.
We all know that the solar panel is usually installed on the top of the RV, which is exposed to the wind and rain. When it is exposed to the outdoor environment for a long time, dust and sundries inevitably adhere to it and put it on “thick clothes”, resulting in the reduction of its power generation efficiency.
In addition, the load resistance formed by local shadow shading will reduce the power generation, which may even lead to combustion and fire for a long time.
Regular inspection of fixing screws and brackets can also prolong the service life of solar panels to a certain extent and provide guarantee for your travel power consumption.
I believe each of you wants your solar panels to work well and generate a lot of electricity.
So, how should you maintain the solar panels?
- In terms of time, the cleaning of solar panels is generally carried out in bad sunshine conditions, such as morning or evening.
- Before cleaning the solar panel, check whether the solar panel is damaged and whether its connecting wires and relevant components is damaged;
- Do not use hard and sharp tools or corrosive solvents and alkaline organic solvents to wipe the solar panel, and try to choose some soft tools, such as sponge, cotton towel, etc.
- Pay attention to the cleaning of the whole solar panel, especially the corner positions, where dirt is easy to accumulate, so as to avoid the load resistance caused by local shielding and affect the power generation efficiency.
- If the solar panel is fixed by screws, the screws need to be checked regularly. Although many screws have good oxidation resistance, soaking in snow and rain for a long time may still affect the screws. Regular inspection is needed to ensure firm installation.
In addition to maintenance and cleaning, excellent solar cell are also the guarantee of power generation efficiency.
In fact, considering the influence of various environmental factors and installation factors, the premise is that the solar cell must be brand-new and high grade.
If other grade B, grade C and grade D solar cells are used instead of brand-new and high grade solar cells, there will be color difference, color spot, water mark, finger print, positive electrode damage, scratch, edge collapse, angle loss and other problems, resulting in power loss. You bought a 100W solar panel, but in fact it is less than 100W. No matter how you maintain it, its power generation effect is greatly reduced. Even some will have hot spot effect, resulting in gradual heating, short circuit and combustion risk.
High-quality solar panel manufacturers use high-quality solar cells, which do not contain any excessive electrical function or poor appearance, so as to ensure sufficient power generation efficiency, fine and standardized production process, protect the cells from damage, 100% El test to ensure no hot spots, and PID potential induced attenuation, tension, bending, glare, temperature and smoke test, so as to ensure the power generation efficiency and service life of solar panels in the environment of long-term movement, shadow, high temperature, high humidity, low temperature and wind and snow.
The solar panels they produce have the following characteristics:
- High-quality material and process: high-quality silicon wafer and strict process are adopted to effectively control and avoid potential induced attenuation of PID;
- Specially designed for RV: built-in bypass diode is suitable for the scene where the RV moves and changes. It can still generate electricity under the environment of occlusion and shadow to ensure efficiency;
- Warranty: refuse false bid, guarantee sufficient power, guarantee 25-year power generation efficiency and prolong service life;
- Authoritative test guarantee: ensure the power generation efficiency and service life under various harsh environments through rigorous tests such as attenuation and tension.
