Solar pool heat and solar electric generation and storage

October 3 @ 10:00 am - 2:00 pm UTC-7

Free

We purchased the home due to its orientation with the majority of the windows on the south side of the home with the entire south side shaded by a patio. We first added solar pool heat and a variable speed pump. Next, we had a 3.1 kW solar generation system installed. Our electric company, SRP, places the home on a special rate plan that significantly reduces the rate per kWh. However, credit for excess generation is also at that reduced rate. Therefore, it is not cost-effective to install a large generation system. In addition, SRP charges for demand during peak times (5a-9a and 5p-9p during the winter and 2p-8p during the summer). Therefore, it is cost-effective to install a demand manager to shed loads during peak times. We recently added a 12kWh battery system to assist with our demand during peak times. The battery system recharges from a combination of solar generation and the grid. The battery system also supplies power to protected loads like our refrigerator, freezer, and office equipment during a grid outage. In order to reduce our demand, we had our HVAC ducts repaired or replaced and sealed. We increased the attic insulation to R49 and added a radiant heat barrier. Our windows are original, 31 years old, thermopane. They do not leak and since they are shaded, do not require replacement. We added solar screens on the east and west windows. The former owners of the home were on a $250/month plan with SRP. Prior to the battery system being installed, our electric bill was $150/month. We expect it to reduce to $100/month.
