Going solar sounds like a no-brainer in sunny California—but the truth is, not all Residential Solar Installations in CA go smoothly. Between choosing the wrong equipment and cutting corners on installation, a few common mistakes can turn an eco-friendly dream into a costly headache. Here are the top five to watch out for.
- Skipping the Roof Inspection
Before a single panel goes up, your roof needs to be in good shape. Installing solar on a weak or aging roof is like building a house on sand—it won’t last. Have a professional inspect it first. If repairs are needed, it’s better to handle them before the panels go on.
- Choosing the Cheapest Option
Everyone loves saving money, but when it comes to solar, the lowest bid isn’t always the best deal. Cheaper systems can mean lower-quality panels, inefficient inverters, or limited warranties. You’ll save more long-term by choosing reliable equipment and an experienced installer.
- Ignoring Local Permits and Regulations
California has some of the nation’s most progressive solar policies—but also some strict rules. Skipping permits or ignoring local codes can cause delays, fines, or even removal of your system. Always work with a contractor who understands your city’s requirements for a problem-free Residential Solar Installation is CA.
- Poor Placement or Shading Issues
Solar panels need sunlight—lots of it. Even partial shading from trees, chimneys, or neighboring buildings can reduce efficiency. A good installer will map out your roof’s sun exposure and design the system for maximum output year-round.
- Forgetting About Maintenance
Solar systems are low-maintenance, not no-maintenance. Dust, debris, and bird droppings can reduce performance. A quick annual cleaning and inspection can keep your panels running efficiently for decades.
