Plan SREC cashflow for solar installations and upgrades. Adjust production, pricing, escalation, and downtime today. Print tables, export files, and share results with teams.
| Scenario | System (kW) | Annual kWh | SREC Price | kWh/SREC | Year 1 SRECs | Year 1 Gross |
|---|---|---|---|---|---|---|
| Rooftop retail | 100 | 140,000 | $30.00 | 1,000 | 140.000 | $4,200.00 |
| Warehouse canopy | 250 | 350,000 | $22.50 | 1,000 | 350.000 | $7,875.00 |
| Construction office trailer | 25 | 33,000 | $45.00 | 1,000 | 33.000 | $1,485.00 |
SREC revenue is governed by eligible production, reporting rules, and contract pricing. This calculator converts annual energy into certificates using the selected kWh-per-SREC factor, then applies downtime to reflect outages, curtailment, and monitoring gaps. For construction budgets, treat Year 1 results as a baseline for bid comparisons and owner payback discussions. Include any broker fees or registry charges separately if they are deducted from SREC proceeds.
When meter data exists, use annual kWh to mirror verified performance. For early-stage planning, specific yield links array size to expected kWh, useful for rooftop and canopy designs. Downtime can be set to match commissioning delays or seasonal access constraints. The example table shows how system scale and price shifts change first-year gross revenue materially.
Annual degradation reduces kWh each year, lowering SRECs even when pricing stays flat. Price change can model declining market values or contractual escalators. Over longer terms, small percentage changes compound, so the yearly breakdown helps identify inflection years. Use term length to match program eligibility windows or negotiated contract durations on multi-year projects. For conservative estimates, apply a negative price change and shorter terms to stress-test cashflow.
Gross revenue is reduced by annual O&M to estimate net cash available to the project. Enter cleaning, inverter servicing, monitoring fees, or insurance adders as a single yearly amount. If O&M is seasonal, use an average value to keep cashflow comparable across alternatives. Net figures support budget forecasts, change-order justification, and lifecycle cost narratives for stakeholders.
NPV discounts yearly net cashflows using the selected rate to reflect time value of money. Higher discount rates reduce present value, which can be important for capital committee reviews. Export CSV for full audit trails and handoff to estimating teams, and export PDF for quick client summaries. Store reports alongside project files to keep assumptions transparent during procurement and closeout.
It is the energy required to create one certificate. Many programs use 1,000 kWh per SREC. If your registry uses a different conversion, enter that value to keep SREC counts correct.
Use annual kWh when you have metered or modeled production for the exact site. Use specific yield during early design, when you only know system size and an expected kWh per kW-year.
Increase downtime to represent months not producing or not reported. For a half-year start, a 50% downtime is a quick approximation, then refine with measured data once the system operates.
NPV discounts future net cashflows to today’s value using your discount rate. Cash received later is worth less in present terms, so NPV will usually be below the simple sum of net revenue.
Yes. Add recurring fees into annual O&M, or reduce the SREC price to a net price after deductions. Use one consistent approach so CSV and PDF reports remain easy to audit.
No. It estimates revenue based on your inputs and assumptions. Market prices, eligibility rules, and production vary by program and site. Use it for planning, then confirm with local program documents and contracts.
