<h2>Is Your Old Solar System Still Performing?</h2><p>Solar panels degrade at roughly 0.5% per year. A 10-year-old system is producing about 5% less than when it was new — which is manageable. But if your system was poorly installed, uses outdated technology, or has a failing inverter, the losses can be far greater.</p><h2>Signs Your System Needs Attention</h2><ul><li>Your electricity bills haven't reduced as expected</li><li>Your monitoring app shows lower output than your system's rated capacity</li><li>Your inverter is more than 8–10 years old</li><li>You have micro-cracks or discolouration on panels (visible during inspection)</li><li>You're on an old feed-in tariff that has expired</li></ul><h2>Upgrade Options</h2><h3>Option 1: Inverter Replacement</h3><p>If your panels are still in good condition but your inverter is failing, replacing just the inverter is often the most cost-effective upgrade. Modern hybrid inverters also allow you to add a battery later.</p><h3>Option 2: Add More Panels</h3><p>If your roof has space and your inverter can handle additional capacity, adding panels to your existing system can significantly boost output.</p><h3>Option 3: Full System Replacement</h3><p>For very old systems (10+ years) with outdated panels and inverters, a full replacement with modern high-efficiency panels often delivers the best long-term return.</p><h3>Option 4: Add a Battery</h3><p>If your system is still performing well but you're exporting a lot to the grid at low feed-in rates, adding a battery is often the highest-ROI upgrade available.</p><p>Makn Energy offers free system health checks and upgrade assessments.
