While building an addition on our home in Phoenix, we are adding a swimming pool. I'm looking for advice on the best overall plan for heating our pool and maximizing pv solar.
Background Details
Our home is currently 1,300 sq ft and we are adding on and additional 700 for a total of 2000 sq ft. Currently, we have a 6.5kw Tesla, Solar City, system that we inherited from previous owner. We've got about 10 years left on the lease and I can't find anyway out of it (believe me I've tried). The system is (28) Yingli 235 panels and a Fronius IG Plus 6.0.
The home was built in 40s and is made of block so insulation is garbage. During addition, we are removing older packaged AC unit and installing a split heat pump which should be more efficient. Our home is completely electric. We moved and upgraded electrical panel to 400A service. We've got a Trutankless hot water heater that should be sufficient for indoor hot water. We are grandfathered into APS net metering plan for installs prior to 2017.
We are adding a pool that is 30' x 12' with a 3/5/3 depth with a couple of small bajas on each end. We're installing a Pentair VS pump with in-floor cleaners. The pool is only shaded minimally but not subject to direct sun all day.
We've got plenty of additional rooftop space to add 30 panels or more potentially. The new roof is flat but not blocked from sun in any direction.
We are looking to add additional PV solar to cover the additional usage from additional square footage and also looking at options for heating and, potentially, cooling the pool. The issue is that we would only heating the pool for 3 to 4 months a year. The remainder of the year, the solar pool panels would be serving no purpose. From what I've read, solar pool panels are more effecient and cost-effective and than using pv panels with a heat pump.
1) Are we better off using pv panels and heat pump, despite the higher upfront and operational cost, than solar pool heater because the pv panels can supply energy 12 months while pool panels would only work for 3 or 4?
2) If we go PV addition, we would need all new system due to Fronius limit, based on my understanding. Is there a better option or should I just look at this as a new install when researching equipment and solutions.
3) If you've got other suggestions, feel free to send them over. I can scrap lots of things at this point if it makes sense.
Thanks and happy to provide any information needed for clarification.
