Q: Can I hook up a solar panel directly to a battery?

• <div><p>You shouldn&rsquo;t hook up a solar panel directly to a battery. That can damage the solar battery and your appliances over time. Instead, install a charge controller between your solar panel and solar battery. Charge controllers regulate voltage, prevent overcharging, and minimize the amount of electrical current to protect your battery from voltage spikes.</p></div>

Q: Can I install solar panels by myself?

• <div><p>While you can install solar panels by yourself, it can be a complicated process full of lots of manual labor, risky roof work, and knowledge of electrical wiring. Most solar panel installation projects should be reserved for a trained professional&mdash;especially if you plan on connecting your panels to the electrical grid rather than for off-grid use, which doesn&rsquo;t require utility services.</p></div>

Q: What questions should I ask a solar panel company before hiring?

• <div><p>There are a few qualifying questions you should ask a <a href="https://www.angi.com/nearme/install-solar-panels/">local solar panel company</a> before hiring them:</p><ul><li><p>Will you handle permits for the installation?</p></li><li><p>Does your total price include the equipment and labor?</p></li><li><p>How long do you expect the installation process to take?</p></li><li><p>What kind of workmanship warranty do you include with your installations?</p></li><li><p>Who should I contact if I have a problem with my system after installation?</p></li><li><p>Do you install the panels or outsource the work to third parties?</p></li><li><p>Will you file for solar incentives for me?</p></li></ul><p></p></div>

Q: Is installing solar panels worth it?

• <div><p>Installing solar panels is worth it if you&rsquo;re frustrated with paying high utility bills, live in a sunny location, and qualify for tax credits and incentives. Most homeowners cut between $650 and $1,500 from their utility bills each year by installing solar panels. Over the course of your panel&rsquo;s warranty, you could save anywhere from $16,300 to $37,500, though those in sunny areas with high energy costs could save more than $100,000. </p></div>

Q: Are flat or pitched roofs better for solar panels?

• <div><p>You can install solar panels on a flat or pitched roof, but keep in mind that they will need to rest at a 30- to 50-degree tilt for optimal sun absorption. It costs more to install solar panels on a flat roof because you will need to install a framing system and likely hire a structural engineer. If your roof has a pitch of more than 40 degrees, it may not be a good candidate for solar panels.</p></div>

"Art performed a quick and professional installation. The solatube installed in the kitchen provides a lot of needed natural light. Also, my existing attic fan had not functioned for several years, and Art suggested the solar powered fan. Art and Steve removed my old fan and installed the new solar fan. Great job all around.

the old softener was running constantly *went through 100lbs of salt in a day* and we were unable to turn the softener off. Owner of FP came an hour after returning my call; he turned the malfunctioning softener off and scheduled to install a new softener system the following day. His son did the installation with his father (owner of business) checking in periodically to offer assistance.) Very fine people who did a complete job, leaving the work area clean and tidy upon completion of work. Owner checked back with me a few weeks after installation to ensure all was working well.

There are a few qualifying questions you should ask a local solar panel company before hiring them:

Does your total price include the equipment and labor?
How long do you expect the installation process to take?
What kind of workmanship warranty do you include with your installations?
Who should I contact if I have a problem with my system after installation?
Do you install the panels or outsource the work to third parties?
Will you file for solar incentives for me?
