KEY TAKEAWAYS

- NYSERDA incentives greatly improve the business case for commercial solar systems in New York. The NY-Sun Megawatt Block Program is currently active in the Con Edison and Upstate regions.

- NY-Sun incentives reduce the upfront cost of solar power systems considerably, shortening their payback period and increasing their ROI. Depending on project scale and location, the incentive rate can exceed $1,000 per kilowatt of installed capacity.

- If a commercial solar project qualifies for NYSERDA incentives, the 30% federal tax credit is calculated based on the net cost after subtracting the incentive (not the full system price).

- Solar installations must meet a series of technical requirements to qualify for the NY-Sun Megawatt Block Program, and program funding is limited. An experienced design firm like NY Engineers can ensure your project is approved on time.

Commercial solar power is a cost-effective investment by itself, even before financial incentive programs are factored in. Photovoltaic technology costs have dropped by over 50% during the last 10 years, and the average electricity price for commercial users in New York now exceeds 20 cents/kWh. 

At current technology costs and electricity prices, a commercial solar array can achieve a payback period of less than eight years without state and federal incentives. While this can seem like a long time, consider that the typical service life of quality solar panels exceeds 25 years. The financial outlook improves considerably when you factor in the 30% solar federal tax credit and NYSERDA’s NY-Sun Megawatt Block Program.

Here we will provide two simplified financial scenarios that compare the cash flow of two commercial solar PV systems, with and without the NYSERDA incentive.

Commercial Solar PV System without NYSERDA Incentives

Assume a commercial building owner plans to install a 300-kW solar photovoltaic array, and the property is located in the Con Edison service territory. As you can see in the NY-Sun incentive dashboards provided by NYSERDA, a system of this size qualifies for an incentive of $1.00 per watt as of November 2022.

The latest edition of the SEIA Solar Market Insight Report (Q3 2022) reported an average price of $1.71/W for commercial solar arrays. Based on this figure, a 300-kW system has an estimated price of $513,000. Thanks to the Solar Investment Tax Credit, 30% of this value ($153,900) can be claimed by the owner on their next federal tax declaration, which results in a net cost of $359,100.

Under favorable site conditions, you can expect to generate over 1,300 kWh/year for each kilowatt of installed capacity. For a 300-kW solar array, you can expect an electricity output of over 390,000 kWh/year. Considering that commercial electricity prices now exceed 20 cents/kWh in New York, this results in estimated savings of $78,000 per year, equivalent to an ROI of 21.7%

The simple payback period of this project would be 4.6 years, which is excellent for an asset that is expected to last more than 25 years. However, the simple payback period does not apply for many solar power systems, since their costs are spread over several years with loan financing.

  • Assuming a 6% interest rate and monthly payments over 10 years, an upfront cost of $359,100 results in a monthly payment of $3,986.75 ($47,841 per year).
  • Since the solar project saves $78,000 during year one, it can pay off the loan by itself while leaving $30,159 in net annual savings.

Even before the NYSERDA incentive is considered, the financial outlook for going solar is already favorable. The net savings and ROI are improved considerably when the upfront cost is reduced by $1,000 per kW.

Commercial Solar PV System with NYSERDA Incentives

NY SOLAR POWER

When a solar power project is eligible for both cash rebates and tax credits, the cash rebate is applied first, and the tax credit is calculated based on net costs. The calculation above can be repeated considering the NYSERDA incentive of $1.00/W, available for commercial solar systems between 200 and 1,000 kW in the Con Edison service territory.

    • Solar PV system cost, before incentives: $513,000
    • NY-Sun incentive: $300,000 ($1,000/kW x 300 kW)
    • Net cost after NYSERDA rebate: $213,000
    • 30% federal tax credit: $63,900
    • Net cost after both incentives: $149,100

Annual savings don’t change with respect to the previous example, since the same system capacity and sunlight conditions are being assumed. However, the ROI has been increased to 52.3%, since the upfront cost is considerably lower ($78,000 / $149,100). The simple payback period has shortened to 1.9 years.

Under the same loan conditions assumed in the previous example (6% interest, 10 years), the monthly payment is now $1,655.32. Annual loan payments add up to $19,863.84, and the project yields $58,136 in net savings from year one.

Note this is a very simplified example, based on typical solar costs and kWh output. An accurate calculation of project costs and savings is only possible with professional solar PV system design and professional assessment, based on actual site conditions. However, this example shows how NYSERDA incentives can greatly improve the business case for going solar.

When applying for the NY-Sun Megawatt Block Program, there are several important factors to keep in mind. NYSERDA wants to ensure that incentives are used in projects that are properly engineered and installed, which means there are stringent technical requirements. Also consider that program funding is limited, and incentive rates decrease over time, or they may run out completely. As of November 2022, solar incentives are available in the Con Edison and Upstate NY regions, but program funding has been depleted for the Long Island region.
