🔋 Solar + net metering only. This version doesn't yet model on-site battery storage — which can shift your self-consumption, savings, and payback meaningfully. Battery modeling is on the roadmap. For now, a rough proxy: raise the self-consumption % to reflect a battery storing daytime solar for evening use.
Cumulative net cashflow
Your money over time after the upfront cost (and loan payments). Crossing $0 = payback.
Annual savings vs. loan payments
Green = utility savings that year; red = financing cost.
With vs. without solar (cumulative)
Total dollars out the door each way. Lower wins.
Your future bill: generation vs. delivery
Solar offsets generation — delivery & fixed fees you pay regardless. Why the bill never hits zero.
