Many options are available for energy improvement projects.

The most common way of financing is the bank that the customer has a working relationship.

Commercial lenders have special loan programs for energy projects. A common program is the Property Assessed Clean Energy (PACE).

Less common for companies is cash or more common a combo of a loan and cash down payment.

Because of the nature of the savings of an energy project the financing is usually easier to acquire. The savings of the energy project is usually more than the payment for the loan. Some programs have no money down and terms up to 30 years.
