Q: Where is the best place to install solar panels on your roof?

• <div><p>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.</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>

Q: Is the morning sun better for solar panels?

• <div><p>The morning sun can be better for solar panels because it&rsquo;s often brighter and clearer than the afternoon sun. The brighter the sun, the more energy solar panels produce. The strongest rays occur during midday, which tends to be prime time for solar energy generation. Most homes get a mix of morning and afternoon sunlight.</p></div>

Q: Can solar panels be easily removed?

• <div><p>Removing solar panels can be straightforward, but it&rsquo;s not necessarily a simple process. Your contractor needs to prevent damage&mdash;not only to your panels but also to your roof and electrical system. Many systems are wired into the main electrical grid, and you&rsquo;ll need to hire a licensed electrician to disconnect it.</p></div>

Q: How often should solar panels be replaced?

• <div><p>Homeowners replace their solar panels after 25 years. That said, you don&rsquo;t necessarily need to replace them at the 25-year mark. You&rsquo;ll notice a declining ability to produce electricity over time. Most homeowners spring for a replacement when they notice their energy bills creeping up to regular levels or when solar panel repairs are extensive, frequent, and no longer economical. </p></div>

"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!"
