East and west facing roofs are also a good option because they get a lot of sun.
Are solar panels good for my house.
Solar panels have an expected life span of about 25 years.
If your roof is aging or damaged you may be better off replacing it before you install the panels.
That means homeowners with high electricity rates from their utility are the ones who save the most when they switch to home solar power.
Although some surveys show that solar panels increase the value of a house you won t know until you sell.
Solar panels should be installed on roofs that are in good condition and will not need to be replaced in the near future.
Considering that your savings from high efficiency solar panels could pay for the cost of a re roof in as little as five years after installation it may be worth it to do any needed roofing work before your solar installation.
