Hi All, thanks for taking the time to read this!!
I'm currently trying to decide on a solar PV system to get installed on my house. I've a budget of £9K and whatever I don't spend on the solution will just get paid off the mortgage.
I'm limited to 16 panels/4kW. Roof faces SE and there isn't a lot of shading, i'd guess about 10% of the roof for a few hours in the morning, Oct - Feb. I'm in Northern Ireland btw.
So far I've got 4 quotes from 2 companies with a 5th on the way from another company.
Key selling points for each seem to be warranty length, and quality of the panels and inverters. I can only take them at their word on this as I don't know much about what is good quality and what isn't.
Quote 2 appeals as the optimiser deals with any shading/faulty panels without impacting the whole system and the software for monitoring the system looks great, however I can't see it making the system that more efficient that it will pay for the optimiser (£2k) in less than 10 years, and probably more like 15 or 20. Quote 4 came about because company B doesn't do optimisers but using the micro inverters will let me have a similar level of monitoring.
I'm a bit lost as to which one is the best for a ROI or whether I should look at a different solution?
Any opinions on monocrystalline or polycrystalline panels? Anyone had nightmares with lots micro inverters failing?
Thanks for the help!

- Company A, offering a Solax inverter, Antaris M6 panels and a smart immersion heater - £7,600
- Company A, as above with an optimiser - £9,600
- Company B, offering a Fronius inverter, Q Cell Pro G3 Panels and smart immersion heater - £6,500
- Company B, offering enphase micro inverters, Q Cell Pro G3 Panels and smart immersion heater - £7,500.
