Usage and Production
| Estimated Solar Annual Production | Lunar Note
You will get a very high PV estimate. Lunar has flagged this issue to PG&E. PG&E has an advice letter ongoing with California public utilities commission to have the calculations switched, until then the issue will remain as it is and is known by all parties. |
| --- | --- |
| Planned Increase In Annual Usage(kWh) | Annual usage + Increase in annual usage = 100% of solar annual production estimate |
