"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!"

"BlueSel Home Solar did an outstanding job of installing my 7kW residential solar system in May of 2018! They were prompt in getting me information on the design and pricing, which was very competitive. They took care of all applications with the utility and state, as well as permitting with the town. My panels look great and we have had no issues with the SunPower panels or the SolarEdge inverter. In the first year of installation, my total electric cost was $55 ... For the year! I would highly reccommend this product from BlueSel Home Solar!"

Solar Panels questions, answered by experts

Solar water heating systems are not one-size-fits-all. You'll likely work with a team of experts to get the job done—including solar panel installers, plumbers, and water heater installers. A specialist will help you decide if a passive or active system is best for your local weather, home layout, roof stability, and your budget.

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.

The average homeowner needs around 22 solar panels, but the exact number depends on your monthly energy consumption. Your solar professional should size your array to offset your consumption, meaning you’ll need fewer panels if you use below-average amounts of electricity, or more than 22 if you use above-average amounts of electricity. The number of panels also depends on the output of each panel. The average is around 400 watts, but you might need more panels if you install less capable equipment. Since there are so many variables, you should have a professional size your system.

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.

Ideally, you want to place them facing true south. This is different from what a compass shows, which is called the magnetic south. You can find true south by using an online calculator as long as you know the longitude and latitude of your property. Solar panel placement is key to maximizing the energy you generate, so this is an important step.
