What Affects the Cost of Solar and Battery Repairs

Understanding the factors influencing pricing can help you plan your repair more accurately.

1. System Size and Configuration

Larger systems with multiple strings or hybrid setups often require more time and diagnostic testing.
A 4kW system, for instance, may be quicker to assess than a 10kW setup with multiple inverters and batteries.

2. Type of Fault

Minor issues, such as a loose cable or sensor fault, are inexpensive to fix.
However, inverter board failures or battery management system errors can require specialist parts, raising the overall cost.

3. Component Age

Older systems may require replacement parts that are harder to source or no longer supported by manufacturers, leading to higher repair costs.

4. Labour and Accessibility

The ease of access to panels (especially on high or complex roofs) can affect labour time.
Local companies like All Solar Works minimise costs by deploying nearby engineers familiar with Worthing’s property types.

5. Warranty Coverage

If your system is still under manufacturer or installer warranty, some repair costs may be covered.
Always check whether your inverter, panels, or battery have remaining warranty periods.

Solar Panel Repair Costs Explained

Panels themselves are usually durable, but issues can still occur, including:

Typical repair costs:

At All Solar Works, our engineers use 3D mapping and output testing tools to identify the exact source of inefficiency before suggesting a repair — avoiding unnecessary replacement costs.

Inverter Repair and Replacement Costs

The inverter is the most common point of failure in solar systems because it operates continuously to convert DC to AC electricity.

Common inverter issues include:

Repair costs: £250–£600
Replacement costs: £500–£1,200 (depending on capacity and type)

In 2025, hybrid inverters capable of managing both solar and battery storage are becoming standard.
All Solar Works offers upgraded, high-efficiency inverter replacements with extended manufacturer warranties and full reconfiguration included.

Battery Repair Costs and Maintenance

Solar batteries store energy for use during evenings or grid outages. If they’re not performing properly, it could significantly impact your energy independence.

Common battery issues include:

Typical battery repair costs:

At All Solar Works, we service and repair most leading brands, including Tesla Powerwall, SolarEdge, GivEnergy, and Huawei. Our experts also check for software compatibility and optimise battery settings for improved charge cycles.

Preventative Maintenance and Service Costs

Prevention is always more affordable than major repairs.
Annual servicing helps identify potential issues early and maintain warranty coverage.

A typical solar maintenance service includes:

Average service cost: £99–£180 per year

With regular servicing, you can extend system life by up to 5–10 years and ensure continued savings on your energy bills.

How to Keep Solar Repair Costs Down

1. Book annual inspections: Regular servicing reduces unexpected faults.
   
2. Use a local company: Lower call-out charges and faster response times.
   
3. Act early: Don’t ignore inverter warnings — minor faults can become major.
   
4. Keep your panels clean: Dirt build-up can reduce output and create hotspots.
   
5. Upgrade outdated parts: Older inverters and connectors may be inefficient.
