My Givenergy system went offline, so I lost control of it. Ron from STS and Craig from Norfolk Solar were most helpful in diagnosing the problem by phone. Full marks for their patience and ability.

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.

Absolutely amazing service. Ive had a couple of issues with my Givenergy system and couldn't manage to get in touch with Givenergy after they went bust. So I was searching on Google and came across Rons number. I sent Ron a WhatsApp message and got a prompt reply and he resolved the problem I had with my system. I can't recommend Ron enough its not often you get such a good service in this day and age. If you are experiencing issues with your solar system Ron is the man to contact.

After GivEnergy went into liquidation, just my luck, my battery started playing up (internal board crashed). Contacted my installer - not interested! Found Solar tech support on a Google search. Sooo glad I found this company! Ron is extremely helpful and has plenty of experience. He soon confirmed what the fault was, and helped me to get my system up and running again. Now moved my GivEnergy account to Solar tech support, and will definitely use again if I have more issues. Unusual to find such a helpful company in these times, no morons reading scripts, just direct contact with the engineer.

Our SolarEdge PV system with LG batteries had its first hiccup after 8 years of hard work. The Inverter failed. Fortunately I found Solar-Tech-Support who diagnosed the problem very quickly, ordered a replacement unit and fitted it shortly after we received the unit from SolarEdge. Very thorough and professional approach. Thank you, a solid 5 star recommendation.

Big thanks to Ron. He was incredibly patient and helpful over the phone, taking the time to walk myself and the installer through every troubleshooting step. Through lots of testing he figured out the issue was definitely a hardware issue, which allows us to consider our next steps. Support fees are clear and they operate a “no fix no fee” policy. It is rare to find that kind of honesty combined with dedicated phone support nowadays. I highly recommend Ron, if you need help with your solar system don’t hesitate to give him a call.

What the health check covers

Four core areas reviewed from your monitoring data.

Generation performance analysis

12+ months of actual generation versus expected output for your system size and location. Underperforming panels, inverter derating, and seasonal anomalies identified.

Battery health review

Charge and discharge patterns, depth of discharge, BMS events, estimated capacity versus rated capacity, and whether the battery is cycling correctly.

Settings and configuration audit

Export limits, CT clamp direction, charge schedules, system mode, tariff alignment, and firmware version. The most common sources of silent performance loss.

Monitoring verification

Confirm monitoring is live and capturing all data correctly. Check SEG export registration status, and flag any data gaps that could affect payments or warranty claims.

What we check during a solar health check

A comprehensive physical and performance audit across all major systems.

Panel condition

Visual inspection for hotspots, microcracks, soiling buildup, bird damage, and edge delamination that can degrade efficiency or void warranty.

Inverter performance analysis

Measured efficiency against manufacturer specification. Derating analysis, thermal throttling patterns, and firmware version validation.

Battery health assessment

Cell voltage balance, capacity degradation over cycles, charge/discharge curve analysis, BMS event logs, and estimated remaining usable capacity.

DC string voltage testing

Comparison between panel strings and baseline. Identifies failing panels, wiring losses, and voltage imbalances that reduce generation.

AC output measurement

Power quality analysis, frequency stability, and reactive power. Identifies issues that could affect grid export registration or tripping.

Earthing and bonding verification

Continuity testing and resistance checks across all earth points. Critical for safety and compliance with BS7909 and BS7671.

Isolator and switchgear condition

Physical inspection for corrosion, mechanical wear, and proper installation. Verification that manual isolators operate smoothly and isolate completely.

Wiring and connector inspection

Check for MC4 degradation, rodent damage, UV damage to cable jackets, and any loose or corroded connections that increase resistance and fire risk.

Monitoring system accuracy validation

Verify CT clamps are correctly installed and directioned. Confirm monitoring data aligns with actual generation. Identify gaps or sensor failures.

Roof fixings and mounting system

Visual check for loose bolts, corrosion on rails, and structural movement. Ensures panels remain secure in high winds and can't slide or shift.

Why annual health checks matter

Solar systems naturally degrade at a rate of 0.5–0.8% per year under normal conditions. This is expected and typically not a concern. However, undetected faults — failed panels, inverter drift, battery imbalance, wiring issues — can accelerate this degradation significantly. A system losing 10% output silently over two years will have generated thousands of pounds less than it should have, whether through lost generation, missed export payments, or prevented battery charging when you need it most.

Annual health checks catch these failures early, before they compound. Many solar warranties explicitly require evidence of regular maintenance and professional inspection. If you need to claim under warranty later, a gap in documented health checks can invalidate your claim. Battery systems especially benefit from annual checks: cell balancing, firmware updates, capacity testing, and BMS event analysis reveal issues long before the battery becomes unusable.

Early detection of panel faults is particularly valuable — a single failing cell can cause cascading damage to the entire string if left unchecked. Our physical panel inspections identify hotspots, microcracks, and soiling buildup that reduce efficiency. Regular audits also ensure your system remains compliant with safety standards (BS7909, BS7671) and that export registration hasn't lapsed. The cost of an annual health check (£145) typically pays for itself within days if any configuration issues are found and corrected. Proactive maintenance prevents silent output losses and catches system underperformance before it costs money.

Health check vs remote diagnostic

Remote diagnostic — free

Best for: Something is clearly wrong

Active fault codes and errors
Specific issue diagnosis
Rapid troubleshooting (30–60 mins)
Configuration error identification
Remote settings correction where safe

Perfect for urgent faults that need quick diagnosis and possible remote fix.

Health check (£145)

Best for: Proactive maintenance

Comprehensive physical inspection
Baseline performance benchmarking
12+ months of data reviewed
Hidden issues identified early
Warranty compliance documentation

Full system audit — catches silent degradation and configuration drift before they cost money.

Not sure which to book? Use a remote diagnostic if you have an immediate fault. Choose a health check if your system seems fine but you haven't had it checked in over 12 months, or if you want peace of mind before relying on generation for financial decisions. See our remote diagnostic service for more details.

How it works

1
Share monitoring access

Grant temporary read-only access to your monitoring account — GivEnergy, SolarEdge, Sunsynk, Growatt, Solis, or whichever platform your system uses. Takes about 2 minutes.

2
Remote audit (typically 2 hours)

We review 12+ months of generation data, battery performance history, system settings, and event logs. Any settings corrections that are safe to make remotely are applied during this step.

3
Written report delivered within 24 hours

PDF report covering all four areas with a priority action list. Pass/flag status on generation, battery, settings, and monitoring. Clear recommendations with estimated cost where relevant.

4
Optional follow-up call (no extra charge)

If you want to talk through the findings or aren't sure how to act on a recommendation, a follow-up call is included. No time pressure.

FAQ

Frequently asked questions

A health check benchmarks how your system is performing and configured right now — generation, battery, export, settings. A remote diagnostic is fault-focused: it finds what's broken. Book a health check if your system seems to be running but you want to verify it's working correctly. Book a diagnostic if something is clearly wrong — no generation, fault codes, battery not charging.
Yes. We review generation history, battery data, and settings via your monitoring account — we can't audit your system without it. If you've lost access or the account is registered to the original installer, see our monitoring account transfer service first.
Yes. New systems routinely have misconfigured settings — export limits set to zero, CT clamps installed backwards, charge schedules not aligned to the tariff. These cost money silently from day one. A health check typically pays for itself within weeks if any of these are found.
Findings are listed in priority order in the report. Settings issues we correct during the session where safe to do so. Hardware faults that need on-site attention are clearly flagged with recommended next steps. You're not committed to any further work — but a fixed-price quote is available if you want it.
Annually is ideal for most systems — particularly battery systems, which benefit from firmware updates and cell balancing. If your system is over 5 years old, two years without a check means accumulated drift that may be silently costing you. New systems (under 2 years) should have at least one health check to catch any commissioning errors. More frequent checks are worthwhile if you're relying on the system for financial projections (export income, battery cycling schedules, etc.).
A remote solar system health check costs £145. That covers a review of 12+ months of monitoring data, a settings and configuration audit, a battery health review, and a written PDF report with priority actions. Settings issues that are safe to correct remotely are fixed during the session, and an optional follow-up call is included at no extra charge.
The remote audit itself typically takes around 2 hours, and the written report is delivered within 24 hours. You don't need to be at home: once you grant read-only monitoring access, which takes about 2 minutes, we work entirely from your monitoring data. Any settings corrections that are safe to make remotely are applied during the session, so most improvements land the same day.
Yes — we support all 19 major inverter brands, including SolarEdge, GivEnergy, Sunsynk, Growatt, Solis, Victron, Tesla, LG, Hyundai, and more. We also work with any panel manufacturer and battery type. If your system uses an unusual or very new brand, ask first — but we're confident we can audit it. The health check is fully brand-agnostic.
