Match the inverter to your panel array and peak load, not just your roof size. As a rule of thumb, keep the array-to-inverter ratio near 1.1 to 1.3 so you capture most of your yield without heavy clipping. Our sizing guides walk through the numbers step by step.
It depends on your tariff, how much you export, and how often the grid drops out. Batteries pay back fastest where net metering is poor or backup matters. We break down usable capacity, cycle life and real payback so you can decide with clear eyes.
String inverters are cheaper and simpler for clean, unshaded roofs. Microinverters and optimisers earn their cost on complex or partly shaded roofs by handling each panel on its own. We compare both on yield, cost and maintenance.
Most shortfalls trace back to shading, soiling, a weak string, or an inverter fault. Start with your monitoring data, compare it against expected yield, and work outward. Our troubleshooting guides cover the common fault and error codes.
Solar is low-maintenance, not no-maintenance. Plan on occasional panel cleaning, an annual visual and electrical check, and prompt attention to any alarms. A little routine care protects both your yield and your warranty.
