How this service works
Solar panel payback in years, ROI, IRR and lifetime savings from system size and cost, with rate escalation, degradation, incentives and maintenance.
Output
Returns a JSON object with payback_years, roi_percent, irr_percent, net_profit_over_period, system_cost, net_cost after incentives, year_one_kwh production, and a year-by-year milestones array showing cumulative savings and production. Also includes a plain-language note and source attribution.
Example use cases
Homeowner evaluating solar ROI
“I'm thinking about going solar — the installer quoted me $3.10 per watt for a 10kW system and my utility rate is $0.16 per kWh. Can you calculate the payback period, lifetime savings, and ROI, assuming I get the 30% federal tax credit?”
Comparing solar bids by cost per watt
“I have two solar quotes: one is $2.75 per watt and one is $3.25 per watt, both for a 7.5kW system. My electricity rate is $0.13 per kWh and I'll get a 26% incentive. Can you run the payback and IRR numbers for both so I can compare?”
Commercial property investment analysis
“We're evaluating a 50kW commercial solar install at $2.50 per watt with an electricity rate of $0.12 per kWh and no tax incentives. What's the IRR, payback period in years, and projected net profit over the system lifetime?”
Technical details
Endpoint
GEThttps://saylorinnovations.com/api/solar/payback?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a detailed, year-by-year solar financial model including IRR and degradation-adjusted production, especially when the user provides system size, cost, and electricity rate. Prefer over simple payback calculators when rate escalation, panel degradation, maintenance costs, and incentive modeling are needed in a single call.
Side effects
- Missing required parameters (system_kw, cost_per_watt, electricity_rate) return validation error
- Negative or zero values for cost or system size may produce nonsensical results
- Very low electricity rates may yield no positive payback within system lifetime, returning null for irr_percent
- Extreme input combinations (e.g. 0.001 kWh rate) may produce null or unrealistic IRR values
