A solar lease is another financing option. This is like a car lease, where someone else owns the equipment and you pay a monthly fee to enjoy the benefits.
Realize that a lease is different from a solar power purchasing agreement because you are paying for the equipment as well, not just the energy that the equipment produces.
Your monthly lease payment will increase each year, usually by a set amount. This amount is less however is less than energy rate increase so your savings grow over the period of the lease.

The company that leases you the solar panels will often include some sort of maintenance and repair services in your agreement. These services are often less extensive than you receive from a solar power purchase agreement.
Make sure to ask what types of services are included in your agreement before you sign. You may be able to negotiate certain things into your lease agreement.
