This tool compares four energy scenarios over a 25-year horizon. Solar system costs are based on state-average $/W with the 30% federal Investment Tax Credit applied. Battery costs include the ITC as well (per IRA guidelines).
Community solar assumes no upfront cost and a ~10% bill discount, which is typical for most programs. The "do nothing" scenario projects costs assuming a 3% annual electricity rate increase, matching recent historical trends.
All estimates are simplified. Actual results depend on system performance, rate plans, degradation, and maintenance costs.
