  • Help working out if solar system is working normal ..

    Hi

    I purchased my rent a roof system on 29/08/18 and just want to know if anyone thinks its doing its job ok, i have a 1.88kw system, south facing on the East coast of the UK and a roof with med pitch with no shading trees etc.... The system is 8 years old and I've been told the inverter part only lasts 10 years does it just stop or does it only allow less power to transfer ?

    I have been taking readings when i think about it.. Could someone please look at the figures see if they look ok ?

    Thanks shane [TABLE="border: 0, cellpadding: 0, cellspacing: 0"]

    Wait until you have a sunny day near noon and check your output. It should be between 1.2 and 1.8kW.
    The system is 8 years old and I've been told the inverter part only lasts 10 years does it just stop or does it only allow less power to transfer ?
    Typical failure is that it just stops. But they usually last far longer than 10 years.
