Introduction

Installing solar panels is a significant step towards harnessing renewable energy, but what happens if the inverter hasn’t arrived yet? Here’s what you need to know about the potential implications and considerations during this waiting period.

Potential Issues

  1. Increased Panel Heating:
    Without energy extraction, solar panels may experience slightly higher temperatures. This could theoretically lead to increased degradation, particularly in regions with hotter climates.

  2. Energy Production Loss:
    While the panels are installed and exposed to sunlight, they are not generating usable energy without the inverter. This means a loss of potential solar energy production during this period.

Considerations

  1. Global Practices:
    It’s common for solar power stations worldwide, including large-scale installations, to be built in stages. In many cases, solar panels remain unconnected for months or even years without significant issues.

  2. Minimal Degradation:
    Traditional Half-Cut PERC panels experience minimal degradation from heat when not connected, typically around 1% per year. This minimal impact is considered negligible in the long term.

  3. Newer Panel Technologies:
    If your solar panels are of the newer N-Type i-TOPCon technology, there’s even less reason for concern. These panels are highly resistant to degradation, making them robust against any potential issues caused by not being connected immediately.

Conclusion

If your solar panels are installed but the inverter hasn’t arrived yet, there’s no need to worry about significant problems. The primary concern is the missed opportunity to produce solar energy during this waiting period. However, in terms of panel longevity and performance, the impact is minimal, especially with newer panel technologies that are resistant to degradation. Once the inverter arrives and is connected, your system will be fully operational, and you can begin to reap the benefits of your solar investment.
