    I previously described the installation and setup of the solar system on the back (south facing) roof of our house. It was installed by Greenday Renew[See the full post at: The Joy of Solar 3: Making Electricity]

    Big day tomorrow – getting second solar system installed, weather permitting, this time on the front of the house (north facing).



    If anybody hear has any questions on Solar or indeed any renewable I can advise on incentives available both Feed In Tariff and Renewable Heat Incentive.If you have any technical queries please feel free to ask and I will endeavour to help.




    appreciate some advice…

    I’ve recently agreed to have the following PV setup. can you advise if this is “value for money”?

    4KW X 16 panels. Brand: Gallium 833 – supplier site (

    single inverter. Owl monitor + owl heating + hot water controller (iboost) + voltage optimiser + all paperwork (building regs, EPC, etc.) for a grand total of £7K.

    I have a guaranteed SEM annual output of 3356KW

    broken down as follows:

    FIT rate and returns = £0.14 = £482.59
    Elec savings = £0.12 = £256.90
    Export Elec = £0.04 = £80.04

    so an annual return of £819.53

    does this sound ok or have i been mugged off… 🙂



    For some time now I’ve been plucking up courage (mainly) to have my circa 1928 concrete tiles replaced with felt and new tiles and have subsequently decided now is the time to do it and take advantage of having the main south roof fitted with integrated panels.
    I’m getting solar quotes at the moment, but any advice on types of panels, inverters etc would be welcomed. For example, is it practical to try to achieve the capacity to charge our Zoe during the daytime, weather permitting?



    i asked the same question to the sales guy. he told me that any PV system that generates over 5KW is not classed as a residential system and attracts different rates and VAT etc. maybe he was talking BS. who knows, but the zoe would need 7KW for about 4 hours which is quite a high constant demand on the PV… still honestly beleive the eco 7 tariffs are the best way to charge the zoe…

    well thats my 2 cents worth.



    Great blog, I was inspired to get a solar array too. Months after buying my renault I went with 14 LG panels at 300w each and enphase micro inverters because it lasts longer… Hopefully on a good day I can use 3kw while 4kw is grid powered (soz)…
    Still not bad and it was priced at 8 grand but I added a extra panel for a battery storage project(plus it now covers the roof in stead of leaving a blank spot). Which powers my entertainment system and gaming computer… I’ll probably make a video about it later on…
    Anyway thanks for sharing…
