Solar panel quote

I am new in the solar world and if you folks could give opinions on this quote from https://electrifusionsolutions.com - both value for money and quality of proposed components?

EcoFlow Ocean Pro - generation from the system 5011 kWh

• 14 x 485w Longi X10 Himo Artist Black N Type Mono Panels ( 25 years product warranty/ 30 years performance warranty) 
• 1 x EcoFlow 6kw integrated  Hybrid Inverter - 15 years warranty
• 2 x EcoFlow Ocean Pro 5.1kWh battery ( 10.2kwh) - 15 years warranty: 95% depth of discharge: 6,000 charge/ discharge cycles - maximum capacity 15kwh

• DNO G98 Application ( see attached explainer)
• MCS registration and handover pack ( handover pack usually within 10 working days of completion)
• 15 years workmanship warranty

Total Price £10,995If you wanted to add an additional battery to increase the storage to 15.3kwh the price would be £11,967

also if you guys can recommend any good company i can go for as i said this all new to me so do want to get ripped off

A few thoughts to help give you perspective:

1. Longi are a very unethical, low end Chinese brand
2. EcoFlow have a 95% depth of discharge (i.e. your real world capacity will be ~9.8 KW)
3. The installer is clearly quoting a suboptimal G98 application instead of the full 6KW G99 application. This is a red flag as it would restrict your system export potential and return on investment,

For perspective, the installers I use to help others offer:

14 X Eurener 515W bifacial panels (7.2 KWp system size + bifacial gains VS. 6.8KWp)

1 X Tesla Powerwall 3 with Gateway 2 (13.5KW usable with superior cold weather performance. Built in Inverter can be set to 7KW)

~£11.5K installed with 10 year workmanship warranty, G99 application and bird netting included.

You can do much better than the overpriced quote you have shared!

hi thankyou so much i noticed something in your reply you have mentioned 10 year workmanship but the quote i received mentions

• 1 x EcoFlow 6kw integrated  Hybrid Inverter - 15 years warranty
• 2 x EcoFlow Ocean Pro 5.1kWh battery ( 10.2kwh) - 15 years warranty: 95% depth of discharge: 6,000 charge/

The 2nd quote offers a much better battery but I would insist on 1) the Eurener 515W bifacial panels (instead of the Aiko monofacial panels) and 2) 10 year workmanship warranty (instead of 2 years).

You should be paying £11.5K or thereabouts (instead of £12.2K)

Regarding warranties, you should probably be aware that EcoFlow's warranty is generally a one-shot affair.

I have an EcoFlow Stream battery. It has a ten-year warranty. But if it goes wrong and they exchange my Stream battery for a refurbished one, the replacement unit only has a one-year warranty.

Now it's possible that the Ocean range has a better warranty system and the 15 years persists for the duration even if they replace something along the way, but you really need to check the small print.

Teeny question, I see you say the battery is scaleable to 15kWh. I was surprised at that as I was watching some US reviews recently and the specs say it's up to 40kWh (8x batts). [Edit - Looks like the US Ocean Pro batt may be 10kWh, but still scaleable to 8 units, so 80kWh per inverter. M.]

But, I think the UK model may be 3 MPPT's whereas the US one has 8 MPPT's (5kWp each), so they are clearly not identical.

You should also add your daily usage in summer month and in winter month.

Who is your electricty provider, what rates you're on?

Which export tarrif you thinking of getting?

Also whats the main reason behind getting it? Being green, hobby or financial gain?

sajag83

hi my energy provider is Fuse Aug Single Rate Fixed (13m) v3
Unit rate £0.1863 / kWh
Standing charge £0.4003 / day

i use 3142kwh a year

i went ot my cousin and he had them installed recently and he was saying how good it is and how much he is saving with 2 electric cars. also i live in east midlands and i get very good sunlight in my house

Newbie_John

So lets look at numbers:

6kW panels - 6000kWh generation a year, half for self consumption £500 , half exported at 12p so another £350.

With £12k spend you wont earn anything, it will take 14 years to get the money you paid back.

If you put £12k in ISA into T41F 15 years long gilt (5.25%) - the yearly interests would make your electricuty bill free - and after 15 years you will still have £12k. £642 interests every year for 15 years guaranteed.

But doing that you will miss your chance on being green. If you think of further household electrification - EVs - keep in mind that most people here dont use solar electricty to charge them because EV tarris offer lower rate, so solar is not needed for that. Heat Pump? Not much sun in winter so again your mostly at mercy of cheap ToU tarrif.

I dont know your cousin but a lot of people just pass on what the sales people told them, there are ways of making numbers work - more panels, better export rate like Agile Export (variable but more than 12p during peak time), believing in really high prices of electricuty comming and using higher values in calculations (you likely wont get 18p/kWh next year - but who knows..)

I kinda agree with Newbie_John here.

You're using 3142kWh a year, which averages out as 8.6kWh per day. Having 10kWh of battery capacity is a luxury, and there's a case for not having a battery at all.

If you were to fit 6kWp of panels without a battery, it might cost you £6k. You'd still generate those 6000kWh/yr. You might manage to use 1500kWh yourself, saving £300 on your electricity bill. The remaining 4500kWh would be exported and (at 12p/kWh) earn you £500.

That's £800 a year in returns, and payback of £6k in 7-8 years. A better result than the 14-year payback with the £12k solar-and-battery system you're considering.

If you decide in a couple of years that you'd really like a battery, you can add one then. It might not cost any more than the £6-7k extra you're being quoted for it now.
