Distributed photovoltaic power generation systems are now entering more and more households, and more and more people are paying attention to this industry. However, businesses and customers have different understandings of the service life and warranty period of solar energy. Then, how long should the components, inverters, and accessories of the photovoltaic power generation system be warranted? Let's use some of the existing data to analyze it.
1, components
Components are the most expensive part of the entire system and the core of the solar energy system. So, how many years should the solar modules be warranted?
Its warranty varies from brand to brand. We all know that the quality of the first-tier component companies is divided into two categories: one is product warranty, the other is power generation quality assurance, product warranty is generally 10 years, the quality of the components can guarantee product warranty for 25 years; The quantity warranty is 25 years, and the power generation rate is about 20% within 25 years.
2. Inverter
The cost of the inverter is not high. Although the cost is not the highest, it is the only part of the power system in the entire solar energy system. It is also the brain of the solar system. It is very important to convert the DC power collected by the components into AC power. However, an excellent solar energy system must be inseparable from the stable operation and high efficiency of tracking solar inverters. Then, should the solar inverter be warranted for several years?
The choice of inverter is related to the power generation problem of the entire system. Quality assurance of inverters is now guaranteed for 5 years. After the warranty period expires, it is extended to 25 years. Similarly, we can select the world's first-line solar inverter companies to compare quality assurance. However, generally five years of quality assurance is provided.
3, bracket
In addition to solar modules and inverters, there is a major part of the support system.
Bracket is a fixed protection of photovoltaic components, but also the main component of the entire system, and now the bracket material is two kinds of aluminum alloy and steel structure. From the material itself, both types can be used for more than 25 years. However, due to its different processes, there are subtle differences. For example, if the thickness of the aluminum alloy is not enough, oxidation will occur and the sea will be weathered. The steel support system requires a sufficient thickness of galvanized surface, usually a hot dip galvanizing process. The surface is hot-dip galvanized. The average galvanized thickness is 65μm. The basic thickness of the bracket can be equal to or greater than 2.5mm. It has pressure resistance, high wind resistance, corrosion resistance, and the service life can reach 25 years or more. If the surface treatment process and its own strength is not enough, it may be damaged in three to five years.
It needs to be mentioned in particular that the wind resistance capability of the support system, including the forward wind pressure and negative wind pressure, should normally reach 12 or more in coastal cities and reach a maximum of 14; in inland cities, it should be Level 12 is enough.
The bracket system should use materials that have been carefully designed by the manufacturer of the brackets. Mature and reasonable solutions should be selected. They should not be entirely DIY. Designed by experience, especially steel frame bracket systems, should be designed and designed by qualified design institutes. verification. Otherwise, once the wind of the X year comes, the entire solar system will collapse.
4, other accessories
In addition to components, inverters and brackets, the rest are cables, electrical cabinets and other auxiliary materials.
Since cables are common parts, outdoor use should be made of UV protection and anti-aging photovoltaic dedicated DC cables because PV systems are exposed to wind and rain all year round to ensure the service life and corrosion resistance of cables. Cables used indoors should ensure sufficient current-carrying capacity, and communication cables must be capable of anti-jamming capability. The service life can reach more than 25 years.
According to actual conditions of use, other auxiliary materials can be used for more than 25 years without artificial damage.
to sum up
Through the above points, we can analyze that the entire system's life, or warranty should be the shortest product for the deadline, and then through the replacement and maintenance of the equipment for the life of the entire system warranty.
The comprehensive warranty for components is 10 years and the power generation warranty is 25 years;
The inverter's comprehensive warranty is 5 years and can be extended to 25 years.
The warranty for other materials should be 25 years.
