Is $72,072 to install a 27.7kW solar panel system with Silfab 440w panels a fair price?
Project Details
I have whittled my choices down to 2 regional providers. My house has trees around but not much shade on the house currently, and it has 1 chimney. I'm looking to get the maximum sized system for federal credit and net metering in PA, using mostly east/west plus some south facing roofs. I have only been in the house for a little under 2 months, so unfortunately, no yearly energy usage is available. Last month's usage was 1625 kWh, so I'm estimating about ~20k kWh for the year. I am in PPL land. The main reason I was interested in a larger system size was due to the net metering and the SRACs generated by that. I didn't think about PPL throttling production as a potential problem.
