What a fantastic service. Had my fault diagnosed within minutes and actually managed to resolve the issue remotely within a few minutes more. This guy is like a “Solar Batman” helping consumers fix their problems using his extensive industry knowledge and expertise. Outstanding service. Thank you so much.

Andrew Palmer · May 2026

Massively massively recommended. We had a big battery array (49kW across three phases) put in four years ago. c £35k cost. It’s been a total nightmare for many reasons, not least 1. our installer being totally useless and unresponsive and 2. Givenergy, our battery supplier, going bust. Long story short it had never worked anywhere near properly despite countless hours on phones and emails; the best we’d achieved was one third of the batteries working. Rather than write it off, I asked a PM friend to try to source someone who could come on site and review and revive the system. He found Solar Tech Support and Ron. Ron assured us he was the man to get it going again. After so many years of pain, I was not convinced but, true to his word, five hours later it was up and running. Lovely chap, super knowledgeable with a support team to lean on who are also clearly super technical. I honestly didn’t think there was much chance of getting this array going ever again so was absolutely delighted when Ron and team pulled it off. Bravo!

A superb service from Ron who went beyond the normal service received from other Tech support companies. I live abroad and was badly let down when my givenergy system failed (and the company went bankrupt) and the local supplier ran away from the problem. Ron sorted the problem and even accessed specialist coding for the inverter that would not be available for suppliers. Ron also ran a full diagnostic to insure that all was in good working order afterwards. Without Rons support and patient assistance I doubt I would ever have got the system back up and running. Well done and thankyou and you have a customer for the future.

My Givenergy battery stopped working nearly a month ago. After unsuccessfully reaching out to my installer, who looks like he's also busted, I found Solar Tech Support on a Google search. They fixed my issue in a couple of hours. Any frustrated Givenergy customers, I highly recommend these guys.

Prompt and useful support regarding my Sunsynk system lack of performance. Ronald simplified the technical issues to make them understandable. Many thanks, looking forward to follow up.

Patrick Keenan · May 2026

Contacted Solar Tech about my Givenergy battery storage system that wasn't working. Battery status was "idle". Given the company Givenergy had gone bust, I need independent quality technical help. Very patient and clearly very knowledgeable about battery systems Ron diagnosed possible issues and suggested several possible remedies. Worked our way through them and fortunately it began to work. The fault was very specific and only an experienced engineer would have thought to check. Suffice to say I'll be back if I need independent support again. Lastly you only pay if there is a solution. Outstanding.

Quote review pricing

Single quote review
from £75

One installer quote, full written screen + trade-pricing benchmark. Best when you've been pitched by one firm and want a second opinion before committing.

Multi-quote comparison
from £145

2–3 quotes side-by-side with a written analysis — equipment differences, pricing benchmarks, and a clear recommendation on which is technically strongest. Best value if you've done your tendering.

Pair with independent design (upstream)
from £245

If you haven't tendered yet, an independent design (from £245) turns three quotes into a directly-comparable like-for-like — making the sense check much sharper.

What we screen for
Inflated savings projections

Models that quietly assume you'll buy an EV and a heat pump, doubling your electricity demand in the ROI calculation. We cross-check the savings figure against the kWh number on your actual annual electricity bill.

Inflated export rates

Quotes that model your exported solar at 20–30p/kWh because that's the headline of one tariff. Real-world SEG export is typically 8–15p depending on tariff and contract length. The savings claim should reflect the rate you'll actually receive.

Missing equipment SKUs

A quote that says "premium 450W panel" or "GivEnergy hybrid inverter" with no model number is a quote that can be silently downgraded between contract and install. We flag every line item that doesn't name the specific component.

DC/AC mismatch + sizing flaws

UK installs typically run a DC/AC ratio of 1.15–1.30:1. Quotes above 1.40 silently cap your output on sunny days; quotes at exactly 1:1 are leaving generation on the table. We check the maths.

Optimiser misjudgement

Optimisers and microinverters are right for some roofs and wrong for others. Quotes that include optimisers on a south-facing unshaded roof are upselling. Quotes that skip optimisers on a partially-shaded array are under-spec. The reasoning should be in the quote.

High-pressure + finance traps

Discounts that materialise only if you sign today, finance products with double-digit APRs hidden behind "monthly from £X" framing, rent-a-roof clauses that bury 20-year lease obligations in optional small print. We pull all of this into the report.

How it works — 5 steps

1
Send us the quote

Email the installer quote PDF to us, along with a recent electricity bill (so we can pressure-test the ROI claim against your real usage) and a few sentences about what you're trying to achieve.

2
Free 15-minute chat

We call you back, walk through the quote at a high level, flag anything we can see immediately, and confirm whether the paid deep-dive is going to surface anything useful. No obligation — if the quote looks fair, we'll tell you on the call and let you go.

3
Paid deep-dive (optional)

from £75 for a single quote or from £145 for multi-quote comparison. We go line-by-line through equipment SKUs, sizing logic, ROI claims, finance terms, and total pricing benchmarked against trade hardware costs.

4
Written report

Typically 3–5 pages per quote. Red-flag list with severity rating, equipment-spec verification, pricing comparison, ROI sanity check, finance/small-print summary, and recommended next-step questions for the installer. Delivered within 3 working days.

5
Follow-up if you want

Free 10-minute follow-up call after you've read the report. If the report turns up enough that you want to renegotiate, you go back to the installer armed; if not, you proceed with confidence. Either way, your decision is now defensible.

FAQ

Solar quote sense check — frequently asked questions

The big patterns we screen for: inflated savings projections (modelling you as if you already have an EV and a heat pump when you don't), inflated export-rate assumptions (using 20–30p/kWh when SEG reality is 8–15p), missing equipment SKUs ("GivEnergy hybrid inverter" with no model number), undersized inverter for the array (DC/AC ratio above 1.4 silently caps your output), missing optimisers on a roof that needs them, unnecessary optimisers on a roof that doesn't, monitoring listed as an optional add-on (it shouldn't be), scaffolding hidden in the small print, finance APR over 12%, exit fees buried in a rent-a-roof clause, and discounts that materialise only if you sign today.
You email us the installer's quote PDF. We have a free 15-minute chat where you tell us what matters to you — bill cut, EV charging, off-grid resilience, FIT replacement, whatever. For the paid sense check (from £75 per quote, from £145 for 2–3 quotes side-by-side), we go through it line-by-line: equipment SKUs verified, sizing logic checked, ROI assumptions tested against your actual electricity bill, and total price benchmarked against our knowledge of trade prices and reasonable installer margins. You get a written report within 3 working days.
We know what installers pay wholesale for the major inverter and battery brands — GivEnergy, Sunsynk, Fox ESS, SolarEdge, Tesla Powerwall, Pylontech, BYD, the panel manufacturers. We don't share trade-confidential pricing publicly, but we use it as the reference against which your quote's hardware cost is benchmarked. A reasonable installer margin on hardware is 15–25%; quotes pricing hardware at 50%+ markup get flagged in the report.
No. We don't take installer referral commissions and we don't want to. The sense check tells you whether each quote is technically sound and fairly priced — not who you should buy from. If two of your three quotes pass the screen, you choose between them on the things only you can weigh: aftercare reputation, gut feel from the salesperson, lead time, warranty terms, finance fit. We're engineering, not sales matchmaking.
Useful data. If the installer can explain why your roof genuinely needs the spec they've proposed — and the reasoning holds up — great. If they refuse to engage with the technical points, or react defensively, you've learned something about how they'll behave if there's a snag later. Either way, you're no worse off than before the sense check, and probably better armed for whatever happens next.
On average, in the quotes we screen, we find 8–15% of headline price that's either over-priced hardware, unnecessary specifications, or misrepresented savings inflating the ROI claim. On a £10,000 system that's £800–£1,500. The £75 sense-check fee pays for itself many times over even when the quote is broadly fair — and when it isn't, the savings are much bigger. We also catch under-spec that would have cost you years of underperformance.
Both options work, but they answer different questions. Before quotes — get an independent design first (£245), tender that to installers, and the sense check becomes much faster because there's a written spec to compare against. After quotes — send us whatever you've got and we screen each one against industry benchmarks and your own usage profile. Either order produces a defensible buying decision.
Rough benchmarks for a standard installation (May 2026 prices, VAT-free since 2022): 3–4 kWp solar only — £4,500–£7,000; 4–5 kWp solar + 5 kWh battery — £8,000–£11,000; 5–6 kWp solar + 10 kWh battery — £10,500–£14,500; complex roofs (multiple pitches, optimisers, three-phase) add 10–20%. Quotes outside these bands aren't automatically wrong — there are legitimate reasons for premium equipment, complex installs, or unusual sites — but the sense check explains why a quote sits where it does.
