Solar Panel Health Check Manchester
A solar panel health check goes beyond a standard annual service. It is a thorough diagnostic assessment designed to establish exactly how your solar PV system is performing, identify any hidden faults or degradation, and provide you with a clear picture of your system's current condition. This is particularly valuable if you suspect your system is underperforming, if you have purchased a property with an existing solar installation, or if your system has never been professionally inspected.
Manchester Renewables uses advanced diagnostic equipment including thermal imaging cameras, IV curve tracers and string-level monitoring analysis to examine every component of your solar PV system. Our MCS-certified engineers test each panel string individually, assess inverter health and efficiency, check all electrical connections and safety devices, and compare your actual generation against what your system should be producing based on its specification and orientation.
The result is a detailed health report that gives you full visibility of your system's condition, with clear recommendations ranked by priority. Whether your system is two years old or twenty, a health check gives you the information you need to make smart decisions about maintenance, repairs or upgrades.
What Is Included?
Thermal Imaging Survey
Infrared thermal imaging of every panel to detect hotspots, bypassed diodes, cell cracking and connection faults that are invisible to the naked eye. Hotspots indicate cells that are generating heat instead of electricity, reducing output and potentially causing permanent damage.
IV Curve Tracing
Individual string-level IV curve analysis that measures the current-voltage characteristics of your panels under load. This reveals degradation, mismatch, shading losses and individual panel faults that standard voltage testing cannot detect.
Full Electrical Testing Suite
Full electrical testing including open-circuit voltage, short-circuit current, insulation resistance, earth continuity, polarity checks and RCD function testing across every circuit in your solar PV system.
Inverter Efficiency Analysis
Measurement of your inverter's actual conversion efficiency compared to its rated specification. Inverters degrade over time and a unit operating at 90% efficiency instead of 97% is costing you hundreds of kilowatt-hours per year in lost generation.
Detailed Health Report
A detailed written report with thermal images, test results, generation analysis and prioritised recommendations. Designed to give you complete clarity on your system's condition and what action, if any, is needed.
MCS Consumer Code: Protection for system owners and property buyers
Under the MCS Consumer Code, solar installations must be maintained in good working order to remain eligible for warranty claims and government incentive schemes. A professional health check provides documented evidence of your system's condition, which is essential for warranty claims, property sales, insurance purposes and ongoing eligibility for the Smart Export Guarantee.
Why It Matters
- Systems installed during the Feed-in Tariff era (2010-2019) are now 7-16 years old and entering the period where component degradation accelerates
- Thermal imaging can detect cell-level faults that cause up to 30% output loss on affected panels without any visible signs
- IV curve tracing identifies panel mismatch that drags down the performance of the entire string, not just the faulty panel
- Property buyers with inherited solar systems often have no maintenance history or documentation — a health check establishes a reliable baseline
- Insurance claims for solar-related damage require evidence of professional maintenance and system condition
Cost Guidance
A full solar panel health check for a typical domestic system in Manchester costs between £200 and £350, depending on system size and accessibility. This includes thermal imaging, IV curve tracing, full electrical testing and a detailed written report. For larger commercial systems, we provide bespoke quotations. The cost of a health check is typically recovered many times over through the identification of faults that, once resolved, restore lost generation.
