Used solar panels are products that have been used by someone else before but can still be utilized twice. Used solar panels are much less expensive than new solar panels. These solar panels are usually removed from large power stations or replaced due to solar system upgrades. However, used solar panels generally cannot achieve the performance of new solar panels.
Pros: Why would anyone buy used solar panels? The biggest reason is mainly because of the high price of solar panels, used solar panels can save a lot of cost, in addition to the price, some of the used solar panels into a certain test of time, get the user’s affirmation, used solar panels will still have a certain power generation efficiency. We choose to use used solar panels, appropriate to extend the lifespan of solar panels, that is, cost savings, but also to reduce the impact on the environment.
Cons: But on the other hand, if you don’t buy used solar panels from a supplier that is recognized by the market, you may not be able to ensure the quality of the used solar panels. Used solar panels will inevitably have a certain reduction in power generation efficiency, and the maintenance costs may be higher in the later stages of long-term use.
Already useful lifespan: Although the lifespan of solar panels can reach more than 25 years, but used solar panels for sale for different reasons, used solar panels already useful lifespan need special attention. If the used solar panels are used within 10 years, the solar panels are still worth buying at this time. But to used solar panels used has reached more than 20 years, the purchase is not very meaningful, solar panels in the lifespan of the annual attenuation rate of 0.5% to 0.8%, over the lifespan of the solar panels can still be used, but the efficiency of power generation will have a greater reduction.
Brand of used solar panels: When choosing used solar panels, if you don’t know about the performance or efficiency of solar panels, we suggest you to choose the Tier 1 brand of used solar panels, such as Trina, JA, Longi, Jinko, their used solar panels performance will be better than the general brand, and the later use of these panels will bring you more convenience.
The quality of used solar panels: When you buy used solar panels, you have to explain with the merchant or test the quality of used solar panels by yourself in time, such as the surface of solar panels or whether the circuit is intact, and pay attention to the used solar panels purchased to match the power of the home power demand, to avoid the waste of solar panels to generate electricity or unable to meet the demand.
Warranty Label: Some used solar panel warranty labels may be damaged, if the used solar panel warranty label is damaged, you may consider negotiating with the merchant for a modest reduction in the solar panel price. And the lack of warranty may make your later power generation and maintenance appear larger impact. If the used solar panel warranty label is intact, such used solar panels are recommended for you to buy.
Buying used solar panels is a good choice for those who are on a limited budget and still want to improve their solar power generation system. However, it is important to note that when buying used solar panels, the limited lifespan and performance of the used solar panels are important.
