"Sun Bug is a 5/5 star company. I inquired with 4 solar companies and these guys stood out from the pack from day one with a responsive fast estimate, scheduling that was easy, and an installation crew who arrived on time, were neat and cleaned up every day. They did what they said they would do when they said they would do it and now my new solar panels produce enough energy to cover the average daily use, just as they planned. You must call them before you buy."

"My solar inverter stopped working in my existing solar system, and since my original installer went out of business, I had a hard time finding someone to replace the inverter provided by SolarEdge. It was a small job, and most large companies weren’t interested, while those willing to help were booked out for at least a couple of months. I contacted Justin, and he replaced the inverter within just a few days. He was very friendly, efficient, and offered a very reasonable price. Justin was also extremely knowledgeable, explained everything clearly, and kept me updated throughout the process. He arrived on time, completed the work neatly, and made sure the system was running perfectly before leaving. Overall, his professionalism, honesty, and dedication to customer satisfaction made the whole experience stress-free and smooth."

"I initially had reservations about the concept of installing solar panels, but I was keen on getting an estimate and seeking professional advice. That's when I met Arvin. He provided me with a comprehensive walkthrough, clearly outlining the advantages of having solar panels. The entire process was straightforward, with each step being well-explained, leaving no room for surprises or unexpected outcomes. Now, a little over 5 months since the installation, I'm enjoying the benefits just as he promised. I want to extend my gratitude to Arvin for his professionalism and responsiveness. He was always there to address any questions I had, both during and after the installation process. Thank you, Arvin!"

Solar Panels FAQs, answered by experts

Solar shingles and solar panels are not the same. While solar shingles use the same technology as traditional solar panels, they integrate with your existing roof. That means they are used to build your roof instead of simply resting on top of it. When comparing solar shingles and solar panels, it's helpful to know that solar shingles are more aesthetically pleasing than solar roof panels. They also do better in harsh weather due to limited uplift from strong winds.

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.

Solar panels can pay for themselves in five to 15 years, depending on the cost of your system, how much energy it generates, whether you qualify for incentives or power buybacks, and the price of energy in your area. Solar panels pay for themselves over time as they lower electricity bills, so it will take time to recoup your initial investment. However, the longer you have your system, the more money you can save and earn.

In most cases, installing solar panels will not void your roof warranty. To keep roof warranties intact, check your written warranty or call the manufacturer to ask about clauses regarding roof penetrations. You can also protect yourself by getting written approval or a modified warranty that specifically allows the solar installation type you’re planning. Then, hire a professional solar installer that follows roofing manufacturer instructions and protects the roof during installation.

Yes, installing solar panels or a solar roof can increase your home's value by approximately 4% to 6%. For a home with a median value of $429,000, this could translate to an increase of around $17,000. A well-maintained solar installation appeals to environmentally-conscious buyers and those looking to lower their utility bills, often helping homes sell faster and at a premium in areas with high electricity rates. However, the exact increase in value depends on factors like the local real estate market, energy costs, and available solar incentives. It's also important that the system is correctly installed and maintained; an older or poorly maintained system may not add significant value, particularly if it's near the end of its lifespan. Other solar features, like panels on a shed, can also boost your home's value.
