Why don't solar panels produce electricity?

Introduction 7-Day Kill Why Solar Panels Fail to Produce Electricity Due to Angle Issues, Component Aging, and More Angle problem: Solar panels must face the sun to produce electricity. If the installation angle is incorrect, it may cause failure.

Why don't solar panels produce electricity?

Angle issues, component aging, etc.

Angle problem: Solar panels must face the sun to produce electricity. If the installation angle is incorrect, they may not be able to fully receive sunlight.

Aging of components: Over time, solar panels and their components can age, leading to a reduction in power generation efficiency.

If solar panels are easily damaged, the cause of the damage and how long it takes for the actual damage to occur.

The lifespan of flat panel solar energy: Using copper-aluminum composite technology, copper flow channels and aluminum heat-absorbing fins are formed after rolling, and the surface of the plate core is anodized to form a selective heat-absorbing coating, or use a selective coating of highte quality or galvanized black chrome coating.

A. Since the coating material begins to age and turn slightly white after three to five years under the irradiation of the sun and the oxidation of oxygen in the air, this can be seen in the examples of flat installations. solar panel energy projects.

B. The collector copper tubes tend to patina under the action of water and become thin under water erosion, especially the solder joints.

It will be damaged after some years. There is also no denying that it is easy to puncture, and this is true for both flat plate solar heat exchangers and heat pumps using copper tubes.

C. Flat plate solar collectors are metal tube plate structures whose lifespan usually begins to suffer from water leakage and lower efficiency after 5 to 8 years.

The ofLifespan of vacuum tube solar power: Since its material is high borosilicate glass and the inner and outer coatings are not oxidized in vacuum environment, the lifespan is longer of 15 years without external force.

How many years does solar energy typically last?

The above is complete nonsense. I don't know anything about the photovoltaic industry. The purpose of encapsulating cells in solar panels is to increase shock resistance, aging resistance, waterproof performance, lightning protection, etc. Solar panels are generally not easily damaged and have a lifespan of 25 years. In practice, there may be some scratches on the aluminum frame, scratches on the glass, scratches on the back panel, etc. These will not affect the use, but will affect the appearance.

The lifespan of the energy solar has a lot to do with the inner reservoir. Due to different processing methods, the shelf life may be as short as 3 years or as long as 30 years. Some brands will say that they can be used for 15 years when purchased, but they will be disposed of after 10 years of actual use, because the lifespan of the heating tube is only ten years. If it exceeds ten years, the safety factor. will be reduced and the risk of electric shock will easily occur.

Inner coating selection

1 Welding coating, whether you are doing argon arc welding, high frequency welding, manual welding, mechanical welding, Lifespan is generally 3-5 years, some are better 5-8 years.

2? Completely seamless coating, whether inserting or tightening a rubber ring. Since the water inlet and outlet are at the bottom, the pipeline is easy to sway in the wind anear the insulation. also prone to problems. However, the service life is longer than that of welding. The inner tank can grow longer, about 10 to 15 years.

At present, the most advanced inner tank is also completely weld-free, but the water inlet and outlet as well as the air inlet and exhaust ports are located at the top of the inner tank.The siphon principle uses solar hot water, just like a large water tank, with a service life of more than 30 years (the inner material of the tank should be stainless steel 304-2B).

In addition, there are two reasons for the short lifespan of solar energy

1 Vacuum tube

The vacuum tube is the main component of solar water heater. , and its quality directly affects the overall performance of the solar water heater. The performance and quality of vacuum tubes are affected by coating technology and processes such asue cleaning, coating, vacuuming and sealing. Inferior vacuum tubes have low vacuum degree, poor film stability, and are prone to aging and falling, resulting in rapid attenuation of heat collection performance and inability to absorb sufficient heat.

2 Insulation layer

The thermal insulation performance of the solar water heater is determined by the quality of the insulation layer. A good insulation layer has uniform foaming, high density, low thermal conductivity, high temperature resistance, high thermal insulation performance, and is stable and durable.
