Actual Solar Savings for First 3 Months

I saved $144 for the first three months of solar production. That's $48 per month, which is a little higher than the estimated average savings of $46.35 per month. I updated my SCE Rates Calculator model with my actual electric bills and solar production for February through April to calculate my savings (on the first tab in the blue cells).

Kinda funny. When I got my first bill, I was jumping up and down when it was $3. Then I read it closer and realized that it was just the taxes on the KWHs my solar PV system produced for the month. When you go solar, SCE bills you monthly for taxes but only quarterly for your net meter usage.

14 Weeks Solar Production

We hit a new daily high of 13.56 KWH - in fact, we produced over 13 KWH five different times this week. Our rolling 30-day average production is 311 KWH, which far exceeds the target average of 228.6 KWH to achieve the CSI estimated annual production for our system.
