Should you wash your solar panels?
TL;DR
Cleaning solar panels can yield a 2%-5% increase in power output, translating to an annual financial benefit of £60-£150. This makes cleaning worthwhile.
✦ Why It Matters
Consider cleaning your solar panels to potentially increase energy output and financial returns.
Key Takeaways
- Regularly clean solar panels to maintain efficiency.
- Monitor power output ratios before and after cleaning.
- Evaluate the financial implications of upgrading solar panels.
- Be aware of potential tariff changes when upgrading systems.
How It Works
Cleaning solar panels removes dust and debris that block sunlight, thereby increasing the amount of solar energy converted into electricity. The effectiveness of cleaning can be measured by comparing the power output of cleaned panels to those that remain dirty.
⚠ The Catch
Upgrading to modern solar panels may lead to losing a favorable feed-in tariff, significantly reducing financial benefits despite increased output.
