A sudden dip in solar generation can show up quietly. The monitoring app may report fewer kilowatt-hours than expected, an inverter light may change colour or an electricity bill may reveal that the property is importing more power than usual.
That change deserves investigation, but it does not automatically mean the panels have reached the end of their useful life. SWH Electrical Solutions provides solar servicing and maintenance for homes and businesses across the North East and Teesside, helping you identify what has changed and which response is appropriate.
Start With the Change You Can See
Solar output naturally varies with daylight, weather and the season. A short-term reduction during darker or cloudier conditions may be entirely normal, while a sustained change compared with the same period in previous years can point to a system issue.
