Solar PV panels themselves are very robust and rarely develop faults.
If your monthly generation drops suddenly, you may have lost a ‘string’ of panels often due to a faulty MC4 connector. If your solar output reduces to zero, your inverter may well have failed.
Our solar PV audits – either carried out once a year or on demand – include a thorough diagnostic of all the key elements of your PV system. We check your DC and AC isolators, all string currents and voltages, inverter error logs, cable resistance, etc.
Are birds nesting underneath your panels? We can install the latest bird protection system around the edges of your array to keep you ‘bird safe’.
If you don’t have it already, we can also recommend a battery storage solution to capture surplus solar electricity that would otherwise be lost to the grid. You can then use the stored electricity in the evenings and at night when the sun isn’t shining.
Alternatively, we can install a Solar iBoost, or equivalent immersion controller, that diverts excess solar electricity to heat your water.
