Solar Maintenance & Performance Check

Plenty of UK roofs carry arrays that have not been looked at since commissioning. We check whether yours is producing what its size and location say it should.

What we do

Expected-versus-actual generation comparison

Inverter, monitoring and export meter checks

Shading and soiling assessment

SEG registration review — many inherited arrays are not exporting under any tariff

What it costs

Free desk-based check. Site work is quoted separately by the installer.

FAQs

How do I know if my panels are under-performing?

Compare annual kWh against your system size and location band. A shortfall of more than roughly 15% against the modelled range usually points to shading, soiling, an inverter fault or a monitoring gap.
