My current PV system is a 4.857WK with 15 x 325W Q Cells driving SunnyBoy 5.0, which was installed in Sept 2020.
My roof top orientation:
Before going solar, my annual usage from PGE is between 6.5 MWh to 8.2MWh. With my current PV system, estimated production is 6.9MWh. I may be net zero at the end of the year.
House runs on:
I've a gas for heating purposes and no AC.
I want to change the appliances this way, in my order of preference:
I'm planning to add 6 more Q Cells 325W panels (3 each on existing 2 strings) for a total of 6.825KW, with same 5KW inverter. I understand there will be arcing, but overall production will be better. With estimated increase of 2.6MW for a total of 9.586MWh.
I know induction cooking and heat pumps are more efficient than their Natural gas counterparts. Above therms to electrical energy may not make sense.
If you have changed your appliances, what was your experience in terms of energy usage?
My roof top orientation:
- ARRAY PITCH: 30.3° (7:12)
- ARRAY FACING: 258° (WSW)
- SITE LATITUDE: 37.56°

- Gas for heating 22 therms/mo, which is 132 Therms for 6 months that is an equivalent of 4MWh electrical energy.
- Cooking is Gas range and I'm estimating it to be 8 therms/month, 96 therms/year - 2.5MWh electrical equivalent.
- Water Heating is Gas tankless WH and estimating it to be 8 therms/month, 96 therms/year - 2.5MWh electrical equivalent.
I want to change the appliances this way, in my order of preference:
- Gas range to Induction Range
- Gas furnace heating to Ducted split phase heat pump 56K BTU
- Gas tankless to Hybrid Heat-pump
