In this post, I’ll cover how electricity from a new Texas residential solar system is already cheaper than grid electricity costs. I previously wrote an article about, where I compared Tesla versus SunPower for the better system, and I’ll also follow that up with the decision I made and why I made it.
For the last year, our overall average grid electricity cost was 13 cents a kWh. 15,359 kWh were consumed for a cost of $1,936.17. I estimate our panels can produce 13,260 kWh over the coming year, with a total fixed cost of $1,303.56. This gives us an estimated average cost of 10 cents a kWh. Yes, we’ll have to cover the excess electricity in the summer time, and I estimate that will cost us $264.60.
My next plan is increasing the number of panels we have, generating more electricity in the winter months, lowering the thermostat by a few degrees, and running room heaters where we commonly stay. If it was prudent, I would switch our tankless water heaters to electric heat pump water heaters, as mentioned by Joe Wachunas in his. That is phase 3.
