Back in April we got the PTO from SDG&E to start up our newly installed solar panels. It's a 4kW (DC) system with 12 LG335 panels feeding a SolarEdge Inverter. We are very pleased with the first 6 months of operation. The system design was over-sized for our current electric use since I was anticipating adding an EV to our demand early next year. Budget constraints require waiting a bit for the new car.
In the mean time I've been brushing up on my spreadsheet skills (used to build big oil production forecasting spreadsheets for Chevron in my previous life) and am attempting to model the impact to our SDG&E bills once we start charging our new EV. Which, if you are curious, will most likely be a Kia Niro PHEV. I'm now at the stage where I need to proof-check my calculations. I would love t have something to compare my results with to see if I've got something seriously wrong or if I'm in the right neighborhood of the answer. I am wondering if there's a tool available that lets me plug in my anticipated net energy values for On-Peak, Off-Peak, Super-Off Peak periods and NBCs. and then generate what the anticipated SDG&E charges under the EV-TOU-5 and EV-TOU-2 rate schedules might be?
My spreadsheet calculations are currently duplicating our monthly SDG&E bills to within a penny or two so I feel like I can model our electric use and resulting bill under our current TOU-DR rate schedule. It did take me a couple of billing cycles to work out how SDG&E calculates the individual line items in their bill. Not an easy task as those of you that have tried it can probably attest to.
Thanks in advance.
