Return on investment for renewable energy projects compares installation cost to energy savings and incentive values over system lifetime.

ସୂତ୍ର

Calculate: ROI = (annual savings × years - installation cost) / installation cost × 100%
ROI
(annual savings × years - installation cost) / installation cost × 100% — (annual savings × years - installation cost) / installation cost × 100%

  1. 1Calculate: ROI = (annual savings × years - installation cost) / installation cost × 100%
  2. 2Include tax credits (often 30%), net metering credits, maintenance costs
  3. 3Typical payback: solar 6-10 years, wind 6-8 years

ସମାଧାନ ହୋଇଥିବା ଉଦାହରଣ

ଇନପୁଟ୍
Solar install $10,000, annual savings $2,000, tax credit $3,000, 25-year life
ଫଳ
ROI ~450%, payback 5 years
Excellent investment

ଏଡ଼ାଇବା ଯୋଗ୍ୟ ସାଧାରଣ ଭୁଲ

  • Forgetting tax incentives in calculations
  • Not accounting for inflation in long-term projections

Should renewable energy investments be evaluated like other investments?

Yes, though non-financial benefits (emissions, independence) matter too.

How do incentives affect ROI?

Dramatically; 30% federal credit cuts payback from 8 to 5 years, making projects viable.
