The age and condition of your roof also matter. Solar panels are designed to last 25 years or more, so your roof should be in good condition before installing a system. Addressing needed repairs or replacing a roof after panels are installed can be more complicated and costly.
Some homes may be better suited for ground-mounted solar systems, which can offer more flexibility in placement and reduce shading concerns. Whether roof- or ground-mounted, even partial shade or debris buildup can impact performance.
It’s also important to look at your home’s overall energy efficiency. Improving insulation, sealing air leaks, and maintaining efficient heating and cooling systems can reduce your energy needs. Taking these steps first can help you avoid installing a larger solar system than necessary and maximize the value of your investment.
