"The tech (Tyler?) arrived early and went right down to business. Electrical check showed only about 6 of 13 panels were generating. He went up on the roof and began examining the panels and after about 30 minutes came to the door with a cable that was gnawed completely through by some cute little squirrel. There must have been 10 or 12 different areas where gnawing occurred. He replaced the cable and checked the rest -- they were OK. He installed critter guard to protect against hungry squirrels and finished about 2 hours later."

"The tech showed up a little early which I appreciated; nothing worse than being late for an appointment. He quickly diagnosed the issue with our solar system and is working to get a new inverter under warranty from the manufacturer. He also installed a critter guard to keep the birds from nesting under our panels."

"The solar electric system is now installed and functional 5.5 KW Grid tie system. Standard Relewable sub-contracted much of the work, and I had to deal with several Standard Renewable people over the course of the project. I paid in two payments by credit card. They were very slow to make arrengements to take the second payment. There were several times when it was difficult to get response by email. I emailed several times to make the final payment, and could not get them to do so. The conduit in the Attic is run so that it crosses open space at head knocking height. Over all the system is installed and working, but lacks fine touches"

Solar Panels FAQs, answered by experts

Yes, solar panel installation will require permits. The required permits will depend on where you live, as some states and cities have solar-specific permits, while others only require electrical permits to connect to the grid. In either case, it’s best to hire a reputable solar installer in your area, as a representative should handle all of the necessary permitting for you and will include the cost of the permits in your initial solar estimate.

Solar panels have a life span between 10 and 40 years, depending on the type of panel. For example, monocrystalline panels can last up to 40 years, while thin-film ones only last between 10 and 20 years. The longevity also comes down to keeping up with solar panel repairs and their related costs .

While you can minimally overshoot the number of solar panels you need for your home, it's not smart to go too far. Not only is the extra cost unnecessary, but your state may put caps on how much energy your home can produce and send back to the grid. It is always best to work with a solar energy professional to determine the best system size for you.

Depending on the climate in your area, the best time to install solar panels is either winter or early spring. Summer is a fine time to install panels, too, but it tends to be the busy season, so prices may be higher and companies may have packed schedules. The installation process can take more time than expected between getting permits and finalizing a design, so start as soon as you can.

Installing solar panels involves drilling small holes in your roof to secure the solar panel mounting brackets. These brackets hold the solar panels in place and must withstand strong weather conditions so they’re secured into your roof. However, holes and screws are sealed to prevent leaking and further damage.
