OKPhotovoltaic welding ribbonThe bad photovoltaic ribbon will damage the entirePhotovoltaic cellsThe impacts vary significantly, mainly in the following aspects:
1. Power generation efficiency
Good solder strip: High conductivity can reduce series resistance loss and improve the power generation efficiency of the battery.
Bad solder ribbon: Higher resistance will lead to current loss, significantly reducing the power generation of the photovoltaic module.
2. Reliability
Good soldering strip: The soldering is firm, which can effectively prevent cold soldering or false soldering and improve the overall reliability of the component.
Bad solder strips: Poor soldering may occur, resulting in unstable connections between battery cells, thus affecting long-term reliability.
3. Service life
Good welding ribbon: with corrosion resistance and anti-oxidation coating, it can maintain stable performance in harsh environment and extend the service life of photovoltaic modules.
Bad solder strips: prone to oxidation and corrosion, which may shorten the life of the component.
4. Production costs
Good solder strips: Although they are more expensive, they can reduce maintenance and replacement costs due to failures, which is more economical in the long run.
Bad solder strips: low short-term cost, may lead to more failures and higher maintenance costs in the long term.
5. Maintenance frequency
Good solder strips: reduce failure rate, reduce maintenance and inspection frequency.
Bad solder strips: may lead to frequent failures and the need for replacement, increasing maintenance workload.
In short, good photovoltaic ribbons can not only improve the power generation efficiency and reliability of photovoltaic cells, but also extend their service life and reduce maintenance costs, while bad ribbons may have a negative impact on the performance and economy of the overall system. Choosing high-quality ribbons is crucial to the overall benefits of the photovoltaic system.
