Financing your SOMAH project

Property owners have multiple options if the SOMAH incentive does not fully cover the cost of the installation. SOMAH technical assistance is available to help property owners make informed decisions about the most viable financing pathway for their property.

If you decide to purchase a system, you may use one or a combination of options: cash, loans or the federal investment tax credit.

A one-time federal investment tax credit (ITC) is available for residential solar PV systems. The credit is based on a percentage of the total solar PV system cost. If the system is placed in service before Dec. 31, 2019, a federal tax credit of 30% of the total system cost is available. After Jan. 1, 2020, the tax credit will start to decline.

While SOMAH may cover up to 100% of the tenant load, the program covers only a portion of the costs for the common area, therefore, gaps may remain in funding a solar project. This could include costs to cover common area PV, upfront costs, operation and maintenance costs, costs to meet energy efficiency requirements, and other costs that support installation.

Third party ownership (TPO)

This option is most appropriate when a property owner does not have sufficient capital to buy a system upfront or has limited time to manage, operate, and maintain the system. In case of a TPO, the third- party contractor receives the SOMAH incentives and thus the monthly payments are lowered.

  1. Solar Lease
    • Under a solar lease, the property owner or the host customer pays a fixed monthly cost to the system owner.
  2. Solar Power Purchase Agreements (PPA)
    • Under a solar PPA, the property owner or the host customer pays per kilowatt hour of energy produced on a monthly basis to the system owner.
  3. Pre-paid solar PPA/ Lease
    • A pre-paid solar PPA/ lease is similar to purchasing a system. The host customer/ property owners pay 100% upfront cost with no monthly payments.


Other financing options include leasing a system or entering into a PPA. With both agreements, the system is third-party owned and you pay per month. In a lease, you pay a fixed monthly rate no matter how much electricity your system produces. With a PPA, you pay a fixed amount for each kilowatt-hour (kWh) the system produces. The third-party owner will receive the SOMAH incentive, lowering or even eliminating the monthly payments.

Both a lease and a PPA typically are contracted for a 20-year period. Be sure to read and understand the entire lease or PPA agreement before you sign as these contracts will contain many terms and conditions that will remain in place for up to 20 years.
