If you’re thinking about getting solar panels installed, knowing the key stuff contractors look at can seriously save you headaches and cash.

First off, roof orientation and angle are huge. You want your panels facing the right way. usually south if you’re in the northern hemisphere. to catch the most sun. The angle matters too; it should match roughly your latitude to get max sunlight all year. Then, shading analysis is a must because even a little shadow from trees or chimneys can kill your panel’s output. Contractors usually check this with special tools or software, so don’t skip this step. Next up is electrical system compatibility. your home’s wiring and breaker box need to handle the new load safely. Sometimes, upgrades are needed, so budget for that. Also, think about local permits and inspections because you don’t want your setup shut down or fined later. Finally, make sure your installer is licensed and insured to avoid any mess if things go wrong. Oh, and ask about warranties on both the panels and the installation itself.

One of the biggest mistakes contractors see when installing solar panels is ignoring roof orientation and angle, which leads to underperforming systems. Fix: always evaluate and adjust angles to your location. Another common issue is skipping shading analysis, which causes big dips in energy production. Fix: use shading tools or get a pro to check before installing. Lastly, electrical system compatibility problems can cause unsafe setups or extra costs later. Fix: have an electrician inspect your system before starting, so you’re not surprised by upgrades.
