Solar Panels questions, answered by experts

While solar panels can be a great investment, they aren’t ideal for every roof. For example, some roofs, especially older or structurally weak ones, may struggle to support the added weight, leading to potential damage. Roofs with complex designs, obstructions, or limited sunlight exposure might not provide optimal conditions for solar energy production. Consider these downsides when determining if solar panel installation costs are worth it.

You can install solar panels on a metal roof, but it will require some additional thought and care versus a traditional asphalt shingle roof. That’s because heat dissipates off a metal roof differently than asphalt or wood, so you may need to space the panels further from the roof. However, a pro can help you with the details and provide a safe and effective installation.

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.

In almost every case, solar panels need to be removed to replace roof shingles. In some cases, such as solar installations where the panels are on raised platforms above the roof surface, installers may be able to install new shingles without removing the solar installation. However, to get a quality roofing installation, panels need to come off. Most roofing contractors won’t remove or reinstall solar panels as part of a roofing project, so you’ll need to contact your solar provider.

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.
