Paying for a home solar system

What are the main ways to finance solar panels?

There are four common routes. Paying cash is simple and has no interest. A bank or credit-union loan, a home-equity line or a specialist solar loan spreads the cost, and the owner keeps the system and any incentives. A lease turns the system into a monthly payment while the lessor owns the equipment. A power purchase agreement is similar, except the householder pays per kilowatt-hour produced instead of a fixed fee.

Availability of leases and agreements differs across provinces and over time, and some installers do not offer them at all. A municipal or utility programme that adds the cost to the property tax bill also exists in some places, and it should be checked on its own terms.

How does a loan change the cost of solar?

Interest adds to the price, but a loan can still make sense if the system saves roughly as much per month as the payment. Take a simplified example with stated assumptions: a system costing 20,000 dollars, a ten-year loan at 6 percent, and annual savings of 1,800 dollars. The payments run to roughly 2,600 dollars a year, so for a decade the household is paying more than it saves, and the benefit comes afterwards. Change the rate, the term or the savings and the picture changes.

The method is the one in the payback period guide. For a first estimate of the sticker price, see the cost guide, bearing in mind that quotes decide the real number.

What is the catch with leases and power purchase agreements?

The lessor, not the homeowner, usually claims incentives and depreciation, and the contract may run fifteen or twenty years. Several details deserve reading closely:

• Whether payments rise each year, and by how much.
• What happens if the house is sold, and whether a buyer must take over the contract.
• Who insures the panels and who repairs them.
• What the buyout price is and when it can be exercised.

A lien or a registration against the property can complicate a refinance or a sale, so lenders and a lawyer may want to look at the paperwork. The home value guide returns to the resale question.

Which option suits whom?

Households with savings and a long horizon tend to prefer cash, since it avoids interest and keeps the incentive. Households that want to spread the cost often choose a loan, particularly if the rate is below what other debt costs. Leases suit people who cannot pay upfront and are comfortable with a long contract, provided they have compared the total over the term with a loan.

Whichever route is chosen, compare total cost over the whole period, not the monthly figure. A lower payment stretched over twenty years can cost more than a higher payment over ten. Drake Landing was paid for through a partnership of governments and industry as a demonstration, so it offers no template for household finance; the about page describes how the funding worked in outline.

What should you ask before signing?

Ask for the total payments, the interest rate or effective cost, the term, the fees, the incentive treatment and the cancellation terms in writing. Ask whether the production estimate assumes any billing arrangement or incentive that may change; the incentives guide explains how to check. The installer checklist adds questions about the installer itself.

One more habit helps: ask each provider to show the same system under cash, loan and lease terms side by side. Differences that are invisible in a monthly figure become obvious in a table of totals, and a provider unwilling to produce one has told you something useful.
