Ron is incredibly knowledgeable about solar installs in general but knows givenergy products inside out and the key personnel that worked there from the start to the end. My problem was spurious in its nature but Ron spotted it straight away when he understood the installation details. In essence the installers didn’t fit the correct trip switch. He also gave me hope that in the future hardware repairs could be possible but it’s still early days. This guy really is in the know and keen to sucas a business If you need help don’t hesitate
STS were incredibly responsive and helpful In diagnosing an issue with my GivEnergy inverter. Although distance meant it was impractical for me to use them to fully solve the issue, I’m grateful for the help and detail they provided. Don is a real professional gent and a hero in my eyes.
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!
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.
I have a GivEnergy system consisting of two batteries, two inverters and a controlling EMS (Energy Management System) which has not worked since Nov 2025. After six months I discovered Solar Tech Support, reached out to them and Ron phoned me back – how often do you get that service? Could not be more helpful – worked directly with me over the phone, outside what I would call normal working hours. Lucid explanations and we were able to discuss the issues and history using camera and email history. As this was a very rare setup, Ron was able to access an EMS expert in the field to confirm the solution. One sunny day in, I am now only paying for standing charge and a few pence for spikes in grid consumption while battery catches up with house demand.

Who books this
What we check in your snag inspection
Physical installation quality and damage
Panel mounting inspected for alignment, clipping, and secure fixing. Roof tiles assessed for damage or misalignment caused by installation. Cable clips and trunking evaluated for UV rating and durability. MC4 connectors checked for proper seating. Inverter and battery mounting verified for stability and ventilation clearance. Roof penetration seals checked for water ingress risk. Overall workmanship assessed against installation standards.
Cable routing and tidiness
DC cables inspected for proper trunking and UV protection. Cable clips verified as outdoor-rated and properly spaced. Routing assessed for risk of chafing, water traps, or animal damage. Internal cable runs checked for correct placement and secure fixings. AC cabling from inverter to consumer unit assessed for proper gland sealing and safe routing. Cable tidiness evaluated — sloppy routing reflects poor quality and creates maintenance headaches.
Electrical safety and connections
DC and AC isolators tested for correct operation and verified as clearly labelled. Consumer unit connection checked — correct MCB rating, RCD protection, and solar circuit clearly labelled. Earth bond continuity verified. Cable glands inspected for water-tight sealing. All accessible terminations checked for secure tightness. Installation verified as compliant with BS 7671 electrical safety standards for solar PV systems.
Commissioning and performance verification
System generating at expected level for panel array size, orientation, and weather conditions. Battery confirmed charging from solar, not relying on grid import. CT clamps checked for correct orientation — reversed clamps are a common error. Export limit setting verified against the DNO agreement. If EPS (backup power) was specified, switchover functionality tested. Charge and discharge schedules verified as active and appropriate for customer's tariff.
Settings, configuration, and monitoring
Charge and discharge schedules verified as configured for customer's tariff, not left on factory defaults. Battery reserve and depth of discharge settings checked. Firmware version current. Monitoring portal confirmed active and linked to customer's own account — not installer's company account. Monitoring credentials verified as handed over. API integrations (if any) checked for proper setup.
Documentation and labelling
MCS certificate checked for issuance or in-progress status. G98 notification or G99 approval verified. Electrical installation certificate (BS 7671) obtained. Product warranties confirmed registered. Monitoring account credentials handed over to customer. All safety labels in place — DC array label, AC isolator label, emergency procedure label. User manual and maintenance guidance provided. Commissioning checklist completed and signed off.
Cosmetic quality and finish
Cable clips assessed for consistency and correct spacing. Trunking assessed for colour match and no cracks or UV degradation. Roof tile alignment checked where panels mounted. Inverter and battery casing inspected for dents, scratches, or damage. Paint or mounting frame finish assessed for rust, corrosion, or poor preparation. Labels checked for accuracy and readability. Overall aesthetic quality evaluated — good installations look good.
Common snags we find in post-installation inspections
These are real problems discovered during post-installation snagging inspections. Most could have been caught before the installer left, but having documented evidence gives you backing to get them fixed.
Damaged roof tiles
Tiles cracked, misaligned, or broken during panel installation. Installers sometimes leave this damage unaddressed. Needs fixing to prevent water ingress. Safety and cosmetic issue.
Cable clips missing or substandard
DC cables left partially unsupported or clipped with non-UV-rated clips that will degrade. Creates safety risk and poor workmanship appearance.
Trunking UV degradation
Plastic trunking not UV-rated for outdoor installation, or incorrect type used. Will crack and fail within a year or two, exposing cables to weather.
Poor cable routing
Cables routed where they can chafe on roof tiles, guttering, or sharp edges. Potential water traps where cables run. Sloppy overall workmanship.
Roof penetrations leaking or poorly sealed
Holes drilled for conduit entry left unsealed or sealed with incorrect sealant. Creates water ingress risk — expensive to repair later.
Inverter or battery mounting issues
Units mounted in damp locations, inadequate ventilation clearance, or insecure fixings. Long-term reliability and warranty compliance issue.
Panel mounting misalignment
Panels not mounted at same angle or alignment inconsistent. Looks poor and may indicate quality concerns in electrical connections too.
Missing or incorrect safety labelling
DC array labels, AC isolator labels, or emergency procedure labels not installed. Non-compliance with safety regulations.
Monitoring on installer's account
Monitoring portal set up under installer's company account instead of customer's. Customer has no access to their generation data and loses access if installer goes under.
Charge schedules left on factory defaults
Battery charge and discharge windows not configured for customer's actual tariff. System doesn't optimize for time-of-use rates, costing significant savings.
Export limit misconfigured
Set to 0 kW or wrong value — system doesn't export surplus generation to grid, preventing SEG payments.
Documentation incomplete
MCS certificate not issued, G98/G99 not filed, electrical certificate missing, warranties not registered. Creates problems months later.
