Regular maintenance of solar panel array

The use and maintenance of solar panel array directly affects the service life of solar panel, the operation cost and efficiency of solar power generation system. Doing a good job in the maintenance of solar panel array is the best means to maintain the good operation of the system.

Generally, there is no need to clean the surface of the solar panel array, but the exposed wiring contacts shall be regularly inspected and maintained.

The azimuth of the solar panel array is the included angle between the vertical plane of the array and the due south direction (the East deviation is set as a negative angle and the West deviation is set as a positive angle).

Generally, in the northern hemisphere, when the square array faces due south (that is, the included angle between the vertical plane of the square array and due south is 0 °), the power generation of solar panels is the largest.

Common solar panels in the market can be divided into mono, poly and thin film according to the type of solar cell. Mono and poly solar panels account for the largest market share.

Many people will ask: what is the difference between mono and poly solar panels? So whether to use mono or poly solar panel?

Nowadays, solar street lamps can be seen everywhere in China’s urban streets. It is the leader in new energy lighting equipment. On the road of development in the future, it can be imagined that it will be more widely used. The electric energy generated by the endless solar energy in the daytime will bring light and infinite convenience to everyone at night.

The Glass solar house is a fully bright non-traditional building built with glass solar panels and metal frames, so as to enjoy the sunshine and get close to nature. It is a building respected by people pursuing natural fashion at home and abroad. It has many advantages, and the biggest advantage is light transmission.

When it comes to solar energy, I believe you are no stranger. As an emerging renewable clean energy, it has been applied to all aspects of our life. Solar calculators, solar water heaters, solar power stations and even street lamps on the road are powered by solar energy. But have you ever seen a solar power station on water?

This kind of water solar power station not only exists, but also the world’s largest water solar power station is in China.

The usual selection of solar panels for RV:

Glass solar panel:

The advantage is that after overhead installation, there is a certain space with the roof to make the air convection in the space. It can avoid direct sunlight on the roof and save part of the electric energy of the air conditioner in summer; The price is a little cheaper.

Disadvantages: high installation requirements, not beautiful enough.

Flexible solar panel:

The advantages are beautiful, low-key and relatively convenient installation. Note: the lower the temperature of the solar cell, the higher the efficiency. It is attached to the roof flexibly, which is not conducive to heat dissipation, and the efficiency is lower.

The disadvantages are: low efficiency and high price.

Recently, some people asked me: our family wants to install photovoltaic power generation, but the so-called photovoltaic power generation is literally inseparable from sunshine! Isn’t it useless to have cloudy days, rain and snow? Before answering this question, let’s learn what photovoltaic power generation is.

As we all know, the solar system is composed of solar panels, charging controllers, inverters and batteries. The solar inverter is an essential part of the solar system. Its main function is to convert the DC generated by the solar panels into the AC used by household appliances.

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.
