The ubiquitous accumulation of ash and the mud belt at the edge of solar panels have made the owners of industrial and commercial roof photovoltaic power plants almost crazy. It is a high-yield investment, but we can’t see the expected power generation! Obviously, it’s sunshade cooling. The temperature of the solar panel is even hotter than the roof under the scorching sun.

What happened?

If you have to compare advantages, at present, solar photovoltaic power generation has more advantages, because its manufacturing, installation, maintenance, and other costs are lower, and the scope of application is wider.

As the world continues to seek more sustainable energy production methods to protect limited fossil fuels, solar energy technology is developing rapidly. Solar panels have existed for many years. With the passage of time, their efficacy, beauty, and installation convenience are getting better and better.

It is a consensus in the industry that solar energy resource data must be paid attention to in carrying out photovoltaic projects; However, many people ignore the “basic meteorological elements”.

What are the basic meteorological elements?

1. Temperature

1. Solar cell crack

Causes:

A. The solar cell is caused by an external force during welding or handling.

B. The solar cell is not preheated at low temperature and expands after being suddenly exposed to high temperature in a short time, resulting in cracks.

C. The instantaneous temperature is too high during welding.

The solar panel processing technology is an important part of the solar photovoltaic industry chain. By packaging thin solar cells one by one, it can operate reliably in harsh outdoor environments.

At present, the packaging form adopted by the mainstream solar panel processing technology is EVA adhesive film packaging, which is composed of solar panel detection, solar panel single welding, solar panel series welding, solar panel lay up, solar panel lamination, installation frame and junction box, finished product testing, packaging, and warehousing, etc. Each process is closely linked. Therefore, the process level of each process directly affects the quality and grade of products.

More and more American families have purchased roof solar panels for their own reasons of energy conservation and environmental protection. Moreover, the use of solar panels can save electricity bills for all: over a 20-year period, homeowners using solar energy can save an average of $56000 in New York, $63000 in Boston, and $90000 in Los Angeles.

With the increasing scarcity of non-renewable energy resources on earth, the development and utilization of renewable energy has attracted more and more attention. For example, solar energy resources are inexhaustible green and environmental protection new energy products. The state has also issued relevant policies to encourage and support the development and utilization of solar energy.

What is photovoltaic?

Photovoltaic industry, PV for short. 76% of China’s land has abundant light and the distribution of light energy resources is relatively uniform; Compared with hydropower, wind power, and nuclear power, solar power generation has no emission and noise, mature application technology, safety, and reliability.

In addition to large-scale grid-connected power generation and off-grid applications, solar energy can also be stored by pumping, superconductivity, storage battery, hydrogen production, and other ways.

1. Solar power generation uses the natural energy of the sun to generate electricity. Specifically, solar panels capture certain wavelengths of solar radiation and convert it into electricity for homes, calculators, etc.

2. Photovoltaic cells in solar panels cause the reaction between photons and electrons on the atomic scale. When photons (light) collide with electrons, electrons bounce up. The electrons are then captured and directed into available electricity.
