    Surely you want the setup that works best?

    Yes which one would that be? One comes out at 4W and one 4.25W but I do like the sound of the one that can be computer monitored. One has constant ventilation and other starts at 60% humidity. I think the deal breaker will be pipes in the room or not?

    These are solar panels.

    I have to admit I am a bit confused, what has ventilation, humidity and pipes in the room got to do with solar panels.

    I have some Growatt inverters and they can be monitored online and on a phone app. You may have to buy the wifi dongle for it but ask the installer. You do need an installer code to make it work.

    I would go with the panels with the highest output but there's not a lot in it.

    Read reviews online about the panels and inverters offered and choose what has the best reviews and least problems.

    AHSP decisions are the Grant Aerona 3 is their customer service and superior quality over competitors. That is what the contractor says.

    Or  Mitsubishi ECO DAN Air Source Heat Pump-

    This is what AI says:Certainly! Both the Mitsubishi ECO DAN Air Source Heat Pump and the Grant Aerona 3 are excellent options for air source heat pumps. Here is a comparison of the two:

    Feature Mitsubishi ECO DAN Air Source Heat Pump Grant Aerona 3
    Cost £5,000 - £7,000 £5,394
    Warranty 5 years 7 years
    Maximum Power Output 14 kW 13 kW
    Minimum Operating Temperature -25°C -20°C
    Both air source heat pumps are highly efficient and eco-friendly alternatives to fossil fuel boilers. The Mitsubishi ECO DAN Air Source Heat Pump has a maximum power output of 14 kW, while the Grant Aerona 3 has a maximum power output of 13 kW1. The Grant Aerona 3 is priced at £5,394, making it the best air source heat pump for those operating with a tight budget1. It also comes with a longer warranty period of 7 years compared to the Mitsubishi ECO DAN Air Source Heat Pump’s warranty period of 5 years1. The Mitsubishi ECO DAN Air Source Heat Pump has one of the lowest noise outputs amongst air source heat pumps and can operate effectively even at icy external temperatures of -25 degrees Celsius1.

    We are having a whole system put in via ECO4 but don't know which company to go for.

    The options we have been given: 

    1. *HIB* Longi HiMo5 400W All Black Mono solar panel 10
    SolaX X1-3.6T 1ph (inc WiFi dongle) inverter 

    2.  Longi 425w white backsheet solar panel 10
    Growatt MIN 3600 TL-X Dual MPPT 1ph (inc DC isolator) inverter

    Which is more valuable?
    These are solar panels and inverters, that is what you asked about, do some research and see what you like best.

    I would go with the second option for your solar panels.

    Here I would go with the Mitsubishi.

    How big is your house and what is the heat loss?

    They are quite large heat pumps.

    Without the computer/app monitoring?

    I have Growatt inverters and I can view them online and via a phone app.

    You can buy a wifi dongle for them but you need an installer code to activate it. The wifi dongle was about £20.

    Or go with the other option if you prefer, there's little in it.
