I'm more than considering installing a PV system to our house and am new to the system design and recommendation process.
I've read about various systems such as grid tied, hybrid and understand them somewhat.
- Our zip code is 19380.
- We use about 450 kWh per month.
- Well supplied water (220V 15A)
- Cooking, hot water heating and clothes dryer are natural gas fired
- 'Have a Generac 10kW standby generator natural gas fueled (automatic start upon loss of grid power).
- Our roof exposure is South, roof pitch is 12/12 (45°) the roof is new. Roof area is about 435 sf and with cutting down of a few trees we'd have a total of 603 sf roof area for panels.
At this point in my life tax rebates aren't a concern and I would do the installation myself.
That said, the scenario I'd like to plan for (unless it's not practical) PV supplied power with battery backup being able to supply 5 days of grid power loss (no electrical generator) while using reduced power (not using a dishwasher or other heavy power devices) but must be able to supply power to a medium sized refrigerator and freezer. Also, it would be good to be able to have it grid tied so that the PV system can supply our house with power but also feed excess power to the grid.
It would be nice to hire a solar designer (fee for service) that could specifically address these questions or guide me in reasonable direction. The most I can find on the web are "installers".
Do you have any recommendations or suggestions or other ideas?
Thank you,
Peter
