About this service
Solar and battery maintenance checks that generation, storage, monitoring and protective equipment continue to operate as intended. It can include visual inspection, electrical testing, connection and isolator checks, inverter logs, firmware status and investigation of reduced output.
Generation changes with season and weather, so one low day does not prove a fault. Comparison with historical data, string readings and fault logs helps identify whether the issue is environmental, communications-related or electrical.
Common problems we help with
Generation has dropped unexpectedly
Shading, soiling, inverter faults, failed optimisers, string issues or grid voltage can reduce output.
Monitoring has stopped updating
Router changes, Wi-Fi, platform accounts or communications hardware may be at fault while generation continues.
Battery does not charge or discharge
Operating mode, state-of-charge limits, temperature, communications or hardware faults can restrict operation.
Isolator or connector shows heat damage
Poor connections and water ingress require prompt isolation and repair.
How we carry out the work
Review data and fault history
We compare current behaviour with alerts, historical generation and operating settings.
Inspect and test safely
Accessible AC and DC equipment, isolators, protection and electrical values are checked within the agreed scope.
Correct settings or arrange repair
Supported faults are resolved, while manufacturer or roof work is coordinated where specialist access is needed.
What is normally included?
- Initial discussion about the property, symptoms, priorities and timescale
- Assessment of the relevant circuit, equipment, access and existing protection
- A written scope for the proposed solar & battery maintenance work
- The agreed installation or repair work, with disruption kept to a reasonable minimum
- Inspection, electrical testing and appropriate handover documentation
Before the work starts
- Current consumption, proposed generation and the customer’s operating priorities
- Existing metering, distribution equipment and available installation space
- Equipment compatibility, monitoring and safe shutdown arrangements
- Whether backup operation, time-of-use tariffs or future expansion are required
What affects the price?
The price depends on the existing installation and the amount of work required. For solar & battery maintenance, the main factors normally include:
- System capacity and equipment specification
- Cable routes, access and distribution alterations
- Monitoring, backup and control functionality
- Testing, commissioning and coordination with other installers
Testing, certificates and handover
Once the installation work is complete, we inspect and test it and provide the records that apply to the job.
- Operating modes and monitoring demonstration
- Electrical test and commissioning records
- Isolation and shutdown information
- Equipment documentation and maintenance expectations
Solar & Battery Maintenance questions
Do solar panels need cleaning every year?
Not automatically. Pitch, local contamination and observed output determine whether specialist cleaning is worthwhile.
Why is the inverter clipping output?
An inverter may intentionally limit peak power as part of the system design. Persistent unexpected limitation needs data review.
Can an old system be monitored?
Sometimes, through manufacturer options or additional metering, depending on the equipment and communications available.
Booking the work
What happens after you contact us
1. Discuss the job
Tell us about the property, the symptoms or the result you want. Photographs and model numbers are often helpful.
2. Inspect and quote
We check the relevant installation and give you a written quotation showing what is included.
3. Complete and test
We carry out the agreed work, verify it electrically and explain any controls, labels or certificates at handover.
