Output slowly dropping
Generating less than you used to? A gradual drop is easy to miss and worth checking. Tell us what you've noticed and we'll pass it on to an independent technician.

Not every solar fault is sudden. Sometimes generation just drifts downward until the figures no longer look right. Seasonal changes account for some variation, but a steady decline compared with previous years can point to a fault worth investigating.
If you've noticed your Trowbridge system producing less than it used to, send us what you've seen. An independent technician can look at the figures, the equipment and any other factors to work out whether repair is needed.

Set this month against the same month last year rather than against summer figures.
New extensions, trees or neighbouring buildings can change how much sun reaches the panels.
Inverter messages or gaps in monitoring data are worth mentioning alongside the lower figures.
If the cause isn't obvious, fault finding can separate a system problem from other factors.
Tell us roughly how much output has dropped and over what period.
