    Also passed July target yesterday. Got an Hawaii.

    Weather forecast from tomorrow onwards isn't looking so good for rest of July. Not sure if month end projection of 750kWh's will go up or down, so July 2013 record of 775 might be safe.
    Mart. Cardiff. 8.72 kWp PV systems (2.12 SSW 4.6 ESE & 2.0 WNW). 20kWh battery storage. Two A2A units for cleaner heating. Two BEV's for cleaner driving.

    For general PV advice please see the PV FAQ thread on the Green & Ethical Board.

    Cool graph. What system/software do you use to get that please?

    So looks like you could do with 6kWh battery to get all the way through the night?

    It is part of the Moixa Dashboard which is accessed online. There is also a bit more that shows live panel output, what is being consumed and how much is going to the battery. I could put a screenshot of that up as well if anyone is interested.

    When the Moixa system goes offline (which it does occasionally) I only have a digital generation meter which just clicks up the cumulative watts as they are produced. Serious withdrawal symptoms kick in at that stage.

    More battery would be good but Moixa only offer 2or 3kwh options. From about 1.30 or 2.30am I am on a reduced Economy7 tariff so not losing out too much. The Moixa battery will only charge at about 0.38kw so it takes 7-8 hours or so to fully charge from 20% which is fine in summer but may struggle to fully charge in winter. Presumably there are limits on the rate at which other batteries charge but it does seem slow.
