What this calculator estimates
Estimate a residential solar-battery project cost after equipment, installation, electrical upgrades, permits and incentives.
How to use it
Enter Number of battery units; Battery equipment cost per unit ($); Installation labor and balance-of-system ($); Panel or electrical upgrades ($); Permits, design and inspection ($); Estimated tax credits and incentives ($). Select Calculate to update the results.
How the calculation works
Battery equipment cost is multiplied by the number of units, then installation, electrical and permit costs are added. Entered incentives are subtracted.
Worked example: starting scenario
| Number of battery units | 2 |
|---|---|
| Battery equipment cost per unit ($) | 10500 |
| Installation labor and balance-of-system ($) | 6500 |
| Panel or electrical upgrades ($) | 3500 |
| Permits, design and inspection ($) | 1200 |
| Estimated tax credits and incentives ($) | 8500 |
| Estimated net solar-battery project cost | $23,700.00 |
|---|---|
| Gross equipment cost | $21,000.00 |
| Installation, upgrades and permits | $11,200.00 |
| Gross project cost | $32,200.00 |
| Estimated incentives entered | $8,500.00 |
Important limitations
Battery capacity, chemistry, inverter compatibility, backup loads, utility programs, tax eligibility, labor and electrical conditions vary. Verify current incentives independently.
