Our electricity bill came with a credit. This is a first for us. We've had home solar since 2007 and we've never had a negative electricity bill.
As you can see above, for this billing cycle, we used net 87 kWh; and yet our bill is negative. There are a few things that allowed this to occur.
- We are not driving our EVs as much with the new work from home program
- Springtime is great, we get sunshine, but don't have to run the air conditioning (graph below)
- We received a credit for entering our Powerwalls into our local utility's Smart Battery program
This last item on the list is how we were able to receive a credit, yet still some energy use. The 87 kWh is about $4 worth of energy. Along with the $10 connection fee and the various taxes, we owed about $15. Our partial month credit for joining the Smart Battery program was about the same.
Next month we'll receive the entire $20 credit for the battery program, maybe that bill will be negative too.
Below, you can see as the seasonal sun comes out, our net grid use drops.
