What if my generation seems low?

Check: (1) Is the inverter showing error codes? (2) Are any panels visibly dirty or shaded? (3) Has the weather been unusually cloudy? (4) Compare to same month last year. If consistently 20%+ below expected: call your installer for an inspection.

Do I need to submit meter readings?

Some SEG providers require quarterly readings. Others use smart meter data or estimated readings. Check your SEG contract — submitting accurate readings ensures correct export payments.

What's the difference between generation and export meters?

Generation meter: total kWh produced (everything your panels generate). Export meter: kWh sent to the grid (surplus you didn't use). If you have a smart meter, it tracks export automatically — no separate export meter needed.

How do I read my solar generation meter?

How to read your solar generation meter: LOCATION: usually next to your consumer unit (fuse box) or inverter. It's a small meter labelled 'generation meter' or 'export meter'. READING: displays total kWh generated since installation (cumulative). Record monthly and subtract last month's reading = monthly generation. EXPECTED OUTPUT: 4kW system monthly average: 290-350 kWh (varies by season). If your reading is significantly below expected: check for faults. SMART MONITORING: most modern systems have app-based monitoring (GivEnergy, SolaX, Enphase) which is easier than manual meter reading. But the physical meter is your official record for SEG payments. TIP: photograph your meter monthly for records. Some SEG providers ask for quarterly readings.
