PV yield less than expected
Check the solar panel yield history in the VictronConnect app. Check the total maximum power (Pmax) for each day.
Does this match the array power?
To find the potential solar yield per day for a specific PV array size in a specific geographical location, use the MPPT sizing calculator on the solar charge controller product page.
These are some of the reasons why the array is generating less power than expected:
Low sun angle, seasonal differences or morning/evening.
Cloud cover or bad weather.
Shading from trees or buildings.
Dirty panels.
Incorrect orientation and/or inclination.
Broken or faulty solar panel(s).
Issues with wiring, fuses, circuit breakers, wiring voltage drop.
Bad splitters or combiners, or these are used in an incorrect way.
Part of the PV array not working.
PV array design issues.
Solar array configuration mistakes.
The batteries are too small, or getting older, and have a reduced capacity.
