The 20 percent rule for solar panels can help you save money in the long run

Summary

The 20 percent rule for solar panels suggests sizing systems to produce 20% more energy than a home uses. This provides a buffer for higher consumption, seasonal variations, and potential grid credits, leading to long-term savings.

Key Takeaways

1. Sizing your solar panel system to produce roughly 20 percent more energy than your home uses can lead to long-term savings.
2. Excess energy sent back to the grid can result in potential banked-up credit from your energy supplier.
3. The 20 percent rule acts as a buffer against poor weather conditions or periods where your home's electricity output is higher than normal.
