Consider this strategy from Sean McPherson. The point is to get the most dollars out of the solar-sourced electricity you have made. Set your modeling program to take advantage of this opportunity.
Benefits and costs:
The benefit is that you get the most dollar value each day or year.
The cost is that you need to buy and maintain a battery.
The soft savings of outage protection is often reason enough for a customer to install a battery and solar panels to charge it. A natural-gas whole-house battery installation might be $15,000 while a battery and solar panels might be $35,000.
A customer who thinks outage protection is worth $15,000 might also be a person who thinks generating power on the roof is worth $20,000. Your financial analysis for the energy savings potion of the project will have a first cost of $20.000.
