The easiest way is through your inverter display or monitoring app, which shows real-time and historical generation data. A sudden unexplained drop in output can indicate shading, soiling, or a fault. Apollogrid installs systems with smart monitoring as standard — you can check your system's performance from your phone at any time. We also carry out regular performance checks as part of our aftercare service, so any issues are caught and resolved quickly.
