"I paid $62000 to have my roofs repaired - not cheap for a disabled person. Hopefully, thei dropping the ball is not because Im disabled. They removed but did not properly reattach my ATT line to detached garage. Also, there was a fluke rainstorm about 1-1/2 weeks ago and i heard a dripping sound in / near chimney. I complained and Brent Eikanas their contact promised to have supervisor here to check leak TODAY between 10-11 am and anchor the ATT connection like it was before they removed it. They no-showed AGAIN. I had to remind them of other items they needed to do to finish/using my payment as leverage - removing the old gutter all the way - they had only half-way removed it. I have photos and next winter will have to video and record leak in/near fireplace. I had to start documenting because phone call is useless. The workers left nails and some trash too and on Cinco de Mayo, their last day here, they did two structures in 4 hours,"

Solar Panels questions, answered by experts

Yes, you have to get on the roof to cut a hole for solar tubing. It's not possible to complete the job from inside your house by simply cutting through the ceiling. So if you want to go the DIY route, remember to use safe ladder practices. If you’re not comfortable climbing on your roof to install solar tubes, hire a pro who has the tools and expertise to do the job safely.

The average-sized home in the U.S.—around 2,500 square feet—will require between 15 and 34 solar panels to power the whole home. The specific number, however, will have less to do with home size and more to do with how much energy you use each year and the amount of sunlight in your region.

You can start narrowing your search for a reputable solar company by finding local, regional, and national companies that service your area and maintain positive reviews online. You should also check the Better Business Bureau’s (BBB) website to see if the company has complaints filed against them. Next, contact the remaining candidates and ask about installation timelines, warranty coverage, and financing options. Choose a company that offers a labor warranty that lasts at least 10 years and prioritizes cash purchases and solar loans.

Learn about common solar blockers in your area to determine how often you should wash solar panels and the best cleaning method:

  • Soot: If you have a fireplace, soot can disperse and accumulate on the solar panels.

  • Debris, dirt, and leaves: These natural elements require light cleaning. Being close to trees or living in a desert area can cause more of these to accumulate.

  • Pollen: Areas with a high pollen count require more frequent solar panel cleaning, and sticky plant material requires a deeper cleaning.

  • Bird droppings: Bird droppings are binding and more difficult to remove. Keep this in mind if you live near a lot of surrounding trees. 

Yes, going solar really saves money. In fact, according to some calculations, the average homeowner who switches from electric to solar power will save almost $2,000 a year on energy costs. While buying solar panels and switching to solar can be costly up front, the savings add up over time. If you can sell back extra energy or take advantage of tax incentives, your savings can be even higher.
