Current Celina solar installations average $3.00-$3.50 per watt installed, including equipment and labor. Quality matters - higher-efficiency panels may cost more upfront but provide better long-term ROI.

Step 3: Apply Federal Tax Credit (2025 Only)

The 30% federal credit provides direct tax savings. If your tax liability is less than the credit amount, unused portions carry forward to future years.

Step 4: Include State and Local Benefits

• Ohio property tax exemption on solar equipment value
• Sales tax exemption on solar equipment purchases
• Net metering credits from your utility company

Step 5: Project Annual Savings

Calculate monthly electricity bill reductions based on system production and local utility rates. Include projected rate increases for accurate long-term ROI.

Current Electricity Costs:

Celina area utilities charge approximately $0.11-$0.13 per kWh, including generation, transmission, and distribution charges. These rates have increased 2-3% annually over recent years.

Net Metering Benefits:

Ohio's net metering law allows Celina homeowners to receive retail rate credits for excess solar production sent to the grid, maximizing system value during peak production hours.

Rate Increase Protection:

Solar systems shield homeowners from rising utility rates. Over 25 years, assuming 3% annual increases, rate protection adds significant value to your ROI calculation.
