Wondering if solar is worth it in North Carolina? Here’s how we break down the numbers so you can decide if it’s a smart move for your home.
1. Start with Your Electric Bill
Your average monthly bill tells us how much energy your home uses. If your bill is $150/month, that’s about $1,800/year.
2. Project Utility Costs Over 30 Years
Electric rates in NC rise about 2.5% annually. Over 30 years, a $150/month bill could grow to:
- $396/month in year 30
- $91,407 total over 30 years
3. Estimate the Solar System Size
We size your system based on your usage. The formula:
System Size (kW) = Your Bill ÷ 18
So a $150 bill needs an 8 kW system.
4. Calculate Number of Panels
Using 400W panels:
8,000W ÷ 400W = 20 panels
5. Estimate Monthly Solar Payment
- Install cost: $3.00/Watt
- Total cost: $24,000 for 8 kW
- Financed over 25 years @ 4.99% = $128/month
6. Subtract the Federal Tax Credit
30% credit on system cost:
$24,000 × 30% = $7,200 tax credit
New net cost = $16,800
7. Compare Total Costs
- Staying with utility: $91,407
- Solar system (loan + net cost): ~$22,800
- Total estimated savings: $68,600+
