Not sure what assumptions you are making about fountain operating hours. Believe it or not, this particular system averages about 15000 kW per year, some years more, some years less depending on when we start and shut down the fountain. The fountain consumes about 12.3kW and the rest is street...

Guess I am not communicating very well. I used the same tool you did. I am not trying to produce enough electricity on an hourly or daily basis to power the fountain or produce 3-5x starting current. A system that large would be DOA. Our utility manages credits on an annual basis and pays full...

Right, I understand all of that. We could use a 12kW system which we could never sell due to its size and $40-50k price tag. Would not think of going above 12kW since utility credits drop dramatically. A 12kW system will produce annually our total needs. Our utility will pay us retail for that...

Thx for that. Another head wind comes from fact we can not use Federal tax credit since our HOA pays essentially no federal tax. On the other hand, PA has a fantastic net metering arrangement. I also learned to use the PV calculator which a answered all of my questions regarding peak vs average...

Yes, that helps a great deal. Not sure about the noon production. Where does 17.5/6 kW come from? Also, what is “crazy” expensive for an off grid battery storage system for our conditions, ie May through October and 7am through 7pm. I am guessing it is a totally ridiculous scenario.

Will do.

I am not sure it is worth it. That is what I am trying to determine. Not sure what your last paragraph means? Our HOA is concerned about aesthetics. They have banned solar panels on roofs. Individuals can reduce their carbon footprint by selecting a supplier who offers green electricity. We have...

Thanks. Is your estimate for a stand alone system with sufficient storage for 12 hour/day operation rain or shine? Or, does it assume grid connected? What about 3-4x motor start-up peak load? Finally, how much more would it cost if we hired a contractor? Thanks.

Hello, this is my first post. I have a technical background but a pure novice re solar. I am on our HOA Facilities Committee. This morning I was asked to research this question. This looks like a great place to get started. We have a pond fountain which operates from sunup to sundown 6 month...
