Options
Hi MSE,

APPOLOGIES IF THIS POST IS IN WRONG SUB FORUM!

I am searching forum to find the answer however decided to post a topic to get it way faster.
My budget is 10K and I am looking for a reputable Solar Panel company. I am based in South Wales.

Got quote from Celtic Green Energy  
1 unit SUPPLY OF PHOTOVOLTAIC SYSTEM (3.80 kWp)
1 unit SOLIS 4KW 4G DUAL MPPT SINGLE PHASE
10 units JA SOLAR JA SOLAR 380W MONO MBB PERCIUM HALF-CELL BLACK FRAME MC4

I am far from solar panels and really appreciate any help or advice on this quote or better if exists.

THANK YOU!

Have a great day everyoine!

    Seems on the high side to me, that should be closer to 5k.
    4.29kWp Solar system, 45/55 South/West split in cloudy rainy Cumbria.

    I used an installer local to me (in North West England) but they will not travel to South Wales.

    Your quote includes a battery storage system, have you decided that this is financially worthwhile for your circumstances for some reason, or is it just something the installer included without asking? It adds significantly to the cost.
    7.25 kWp PV system (4.1kW WSW & 3.15kW ENE), Solis inverter, myenergi eddi & harvi for energy diversion to immersion heater. myenergi hub for Virtual Power Plant demand-side response trial.

    Thanks for answering. After searching info in internet decided to have a battery as it will help me through winter times... Do you think I will be better of without battery? 
    Can I install it later ?

    THANK YOU!

    The advantage of having a battery installed at the same time as solar is that it only attracts 5% VAT, the same as the solar. VAT would be 20% for a battery installed alone. However, you have to consider the economics of running a battery, which is still fairly marginal unless well managed between solar, TOU tariffs and export tariffs.

    Thanks for answering. So many things to consider as I thought it would be easy. Also, consultant told me that I have only 4Kw panel allowance and I need to apply for C99 form if I need more than 4Kw. My yearly consumption 5kW . This is also very confusing.

    Price seems a bit on the high side compared to what we had to pay for a 6kWp Solaredge system & Givenergy batteries last year, but am aware that prices have increased since then, because of demand.
    If you send us a PM, we can let you have a link to the company we used.

    A decent installer will handle the approval for more than 4kWp for you. It can take some time, as Western Power seem a bit slow at times dealing with approvals. Also, if you are getting a battery, the approval for a higher possible output will be needed anyway!

    As a rule of thumb, I avoid Chinese brands based on horror stories re: their aftersales support. Your quote includes Solis = Ginlong, a Chinese inverter manufacturer and JA Solar = Chinese panel manufacturer. Both are cheaper on the price spectrum.

    With a £10K budget, I would go for the best possible components available if roof space is limited- 

    1) Solar Edge Inverter and Optimizers enjoy a solid reputation. Insist on the 25 year warranty.

    2) LG 440W Bifacial Panel. Come with a 25 year warranty on performance. You would need 9 panels to achieve 4kW but Bifacial panels are unique in that they can exceed this official rating by generating power from both sides of the panel. No additional approvals needed.

    3) A battery makes little economic sense today. If utility tariffs continue rising and battery costs keep falling, I'd revisit this in a few years. 

    If real estate isn't an issue, another school of thought is to purchase larger quantities of older, cheaper panels to be more cost effective. I can't help with this approach but I'm sure others can.




    -  10 x 400w LG + 6 x 550W SHARP BiFacial Panels + SE 3680 HD Wave Inverter + SE Optimizers. SE London.
    -  Triple aspect. (22% ENE/ 33% SSE/ 45% WSW)
    -  Viessmann 200-W on Advanced Weather Comp. (the most efficient gas boiler sold)
