<p>Before you install rooftop solar, it pays to plan carefully. Here are five important things to check.</p><h2>1. Roof Condition and Age</h2><p>Your roof should be structurally sound and waterproof. If repairs are needed, do them before the installation.</p><h2>2. Shading</h2><p>Nearby trees, buildings or poles can shade panels and reduce generation. A good design accounts for shading throughout the day and year.</p><h2>3. System Size</h2><p>Your ideal size depends on your electricity consumption and roof area — not just on the roof you own. Size matches your bill.</p><h2>4. Inverter Quality</h2><p>The inverter is the brain of the system. Choose a reliable brand with good warranty coverage and after-sales service.</p><h2>5. Your Installer</h2><p>Choose a local installer with proven work, honest advice and dependable support. Credibility matters as much as price.</p>
