What is the 20% rule for solar in Lodi?
The 20% rule for solar usually means sizing a system to produce about 20% more energy than expected usage. It is a planning guideline, not a California law. The extra capacity can provide some flexibility when weather, seasonal sunlight, or energy use changes.
For example, if your home uses 10,000 kWh per year, the guideline would suggest considering around 12,000 kWh of annual solar production. Actual system design should be based on your home's energy use and specific site conditions.
