Considerations for Homebuyers Installing Solar Power

Here is an article about general energy-saving considerations for home buyers. After accounting for all these factors, many homebuyers are eager to take the next step and install rooftop solar panels. But to maximize the benefits of installing solar power, there are a few factors to consider when choosing a home.

"Free" solar panels: You could get lucky and find a house with existing solar panels, where a previous homeowner has already covered the initial investment. However, there is no such thing as a free solar array. The rooftop solar panels will certainly be factored into the selling price. Expect the home price to include $10 to $25 in markups for every $1 in annual savings on the utility bill, as noted in this article. Ask the current homeowner for utility bills to determine the current savings. Do not overpay for the house simply because it has solar panels, but keep in mind that a solar-powered house is likely to sell quickly. You should also consult a qualified contractor and make sure the solar panels are in good working condition.

Roof features: Homebuyers expecting to install new rooftop solar panels should study the rooftop. The ideal location for installing solar power is on a large, open south-facing roof (in the northern hemisphere) because the sun is always in the southern part of the sky. The panels can also be mounted on east- and west-facing roofs, but awkward angles make the panels less sturdy and more difficult to install. On the other hand, a flat roof works because the panels can easily be installed at the optimal angle.

Rooftop solar panels need to be unobstructed throughout the day. Look for a home where no chimneys, roof gables or large trees will shade the panels in the afternoon. Also consider asking a contractor to measure the roof and estimate the space you need to generate a significant amount of your electricity or hot water.

Period of ownership: You can qualify for state and federal tax credits after installing rooftop solar panels. However, if you think you might sell your home in less than five years, you may have to pay back part of the tax credit you will receive for installing solar panels. There might be other restrictions on the incentives that would make solar panels less economical. Research local tax incentives before choosing a home based on its solar capacity.

Restrictions: Homeowners association covenants or local zoning rules could prohibit rooftop solar panels or restrict them to a certain size. Restrictions on solar panels are illegal in many states, but even in these states, you might be forced into a protracted legal battle. If you don't want to rock the boat in your new neighborhood, you may want to reconsider living under a particular HOA's rules.
