Hi everyone

I have been lurking in the forums for awhile trying to absorb all of the information on the multitudes of solar panel quote posts, I would be very grateful if anyone could take a look over the below and say whether they are good / bad

Quote 1:

11 x 405 watt Longi panels (LR5-54HIB-405M), GivEnergy 5.2kwh battery (Giv-Bat5.2), GivEnergy 3.6kw inverter (Giv-HY3.6)

£10536

 

Quote 2:

10 x 425watt Trina (TSM-425 DE09R.08), Growatt 6kwh battery (GBLI6532 ), Growatt SPH3600 inverter

£8724

 

Quote 3:

10 x 410 watt Canadian Solar (CS6R-410MS), Foxx ESS 3.68kw inverter, Fox Ess 5.2 kWh battery (2 x HV2600)

£10499

 

 

I am based in Essex, detached house with a south facing roof approx. 12m x 3m with no shading except for soil pipe vent. Annual usage is currently approx. 3670kwh, no EV (and no real plans at present to get one). 

Have looked through the calculator that’s been linked on other posts and still unsure re battery vs no battery. Am also casting my novice eye over the octopus flux discussions but without a starting point its hard to determine if it would be good for me.

 

2 of the quotes above are from nationals, 1 is from a smaller local firm. Quotes all done via remote survey. Any recommendations for Essex or more local companies would be appreciated.

hi
We have had a similar to your quote 2 set up just over a year ago. 10x400w hyundai panels, 6.2kw growatt battery( later expanded to additional 6.2kw so not in the original price) and SPH 3600 invertor. Cost a year ago £6400 but i know the prices have gone up since then quite a lot. I have written a post recently about our set up, ways we maximalist the returns and our findings. I will be expanding on the post soon as we have making some improvements and trying to crunch the numbers for ROI. I would say yes to battery as it can make lot of savings when charging at night off peak and using in peak times but will require some try and error.

Welcome!

Do you plan to get a heat pump in the future? If not, my advice would be to skip the battery and revisit when you do. Why? Your consumption is at the cusp of what I believe is the point at which batteries start to make sense. Without a heat pump or EV, your consumption may reduce as your replace aging appliances with more efficient ones. The good news is battery tech is only improving.

I wouldn't go with any of your quotes as they are overpriced for the low quality of brands on offer.

10 X SHARP 410W panels + SolarEdge Inverter & Optimizers should cost you no more than < £6K installed. All with a 20+ year warranty on everything. 

And finally, on a South aspect roof, if you can fit any extra panels on your roof now, I'd recommend it. Add £300 for each one you can fit. 

Sorry to jump on to this thread but I just registered so I can. I'm assuming that is a recent quote and from Light Renewables? I've looked on their website which as you said in another post is down, so not sure of their current status, still in business I assume? Could you possible PM me a number so I can give them a call as that system you have spec'd looks idea for me though I may look to add two Pylontech batteries, and a couple more panels if there is room. Also, sorry for all the questions but do you know their lead times, ballpark? 

New webiste is back up and running now.
