Commercial Solar Loans

Commercial solar loans allow building owners to take advantage of tax credits and depreciation. Solar loans deliver lower energy costs and increased Net Operating Income. Capital for the solar system and installation is borrowed from a lender and paid back over time with interest, which provides the borrower with several benefits.

Commercial Solar Loan Benefits

  • The borrower owns the solar system and can apply for tax credits and incentives
  • Solar loans have low down payments and often deliver 120% return of equity through tax credits and accelerated depreciation
  • The monthly savings from a solar loan are likely to be higher than the savings from a solar lease or PPA

Commercial Solar Leases

A solar lease allows building owners to lower energy costs and increase net operating income without the need for immediate ownership. It also allows a building owner to obtain ownership at the end of the lease term. The lessor maintains the system over the duration of the contract and charges a fixed fee to the building owner every month for using the system.

Commercial Solar Lease Benefits

  • Low upfront payments that start at 10% of leased equipment value
  • Lessor pays maintenance and repair costs for the system
  • Reduced acquisition cost at the end of lease term

Solar Power Purchase Agreements (PPA)

Commercial solar PPAs (power purchase agreements) allow building owners to pay for only the power they need. Similar to solar leasing, Sunwest Bank hires a vetted solar installation company to install and maintain the system. In a PPA, however, the building owner pays for the energy generated by the solar system to reduce their overall energy costs and increase net operating income.

Solar Power Purchase Agreement Benefits

  • Save money on energy bills
  • Increase net operating income
  • Purchase only the energy you use, no waste
