Solar System Budget Calculator

Calculate the total cost of your solar installation project

Formula: Total Budget = (System Size × 1000 × Cost per Watt) + Installation Cost + Permitting Fees + Contingency

System Size (kW):

Cost per Watt ($):

Installation Cost ($):

Permitting Fees ($):

Contingency (%):

Budget Breakdown

System Cost: $0

Subtotal: $0

Contingency Amount: $0

Total Estimated Budget: $0

Example Calculation

For a 5kW system at $2.80 per watt, with $2,800 installation cost, $500 permitting fees, and 15% contingency:

System Cost = 5 × 1000 × $2.80 = $14,000

Subtotal = $14,000 + $2,800 + $500 = $17,300

Contingency = $17,300 × 15% = $2,595

Total Budget = $17,300 + $2,595 = $19,895
