Solar PV Inspection, Maintenance and Testing in Plymouth

Service Overview

Solar PV Inspection and Maintenance Specialists

All electrical systems need periodic inspection and testing. Solar PV systems are no different. For PV systems mounted on buildings, the recommended inspection interval will depend on the type and use of the building.

Typical reasons for inspection, testing or maintenance include;

• An obvious fault has developed – for example an inverter has stopped, working or a panel is damaged
• Concerns about reduced returns from your system
• Periodic inspection or routine maintenance
• A change in system ownership to your solar PV installation.
• Water ingress
• To safeguard your investment

What’s the Risks?

In the vast majority of cases, problems won’t occur. Even when they do, the most common problem is reduced system output, undermining your investment returns. Very occasionally however, faults lead to fire or shock risk.

Faults occasionally develop in even the best installed and properly specified PV systems. The most obvious fault is usually an inverter failure, which generally is spotted pretty quickly. However, a loss of 1 or 2 strings in a larger system can be much more difficult to spot, can go unnoticed for months and lead to a significant loss in income.

Monitoring and Fault Alarms

While not an alternative to periodic system verification, an effective remote monitoring and fault reporting system will provide early warning of drops in performance or faults.

Most well designed larger systems should include such a facility. Retrofitting is a practical and effective option where not installed at the outset.

• Power-One: Call it a Riso fault. In Fronius inverters, it is error code 447. If your solar inverter is complaining of this fault then either the inverter is at fault, or much more likely there is something wrong with the d.c. cables between the solar panels and the inverter (for example fault MC4 plug connection getting moisture in). With this fault we will test the electrical connections at the isolators to identify the fault)
