10 reasons why

you should consider having a service and maintenance contract for your home PV system

Mole Energy - Residential
Compliance with IEC 62446

IEC 62446 recommends that periodic verification of an existing installation shall be performed. The standard defines the minimum requirements for system documentation, commissioning tests and inspection for PV systems. As such, this standard not only specifies the minimum electrical testing and inspection requirements but equally importantly how the inspection and test results are documented and supplied to the consumer after installation.Where appropriate, the results and recommendations of previous periodic verifications shall be taken into account. A periodic verification report shall be provided and include a list of any faults and recommendations for repairs or improvements (such as upgrading a system to meet current standards).

Avoiding fire risks

As the number of rooftop solar installation systems have grown over the years, so have the number of reported incidents of fires. Household fires started by electrical faults in rooftop solar PV systems have been reported in the UK, Australia, the USA and France – among others. The periodic testing of the electrical cabling and components associated with solar PV systems will ensure the safe operation of the system and reduce the potential fire risk associated with any electrical faults.

Effective grounding

As with all electrical equipment, solar panels and their racking systems must be grounded to mitigate potential electric shocks and fire hazards. If the grounding system degrades over time, anyone who comes into contact with a metal piece of the system may receive a shock. While the likelihood of shock is low, should one occur, the chance of substantial injury is great because of the high voltage arrays, and the added danger of falling from roof-mounted systems.

Ground faults

PV systems, in particular large-scale systems, have many metres of cabling, much of which is buried underground. Poor levels of insulation will allow energy generated by the PV system to leak to earth. This can be particularly problematic during damp or wet conditions where the insulation monitoring or residual current monitoring function within an inverter prevents the inverter from starting up, which in turn can significantly reduce the operational efficiency of the PV installation.

Environmental degradation

PV systems by their very nature are exposed to the elements. Damage or corrosion to cabling and connectors caused by moisture ingress can result in degradation in performance or increased risk of fire. Regular electrical testing will enable system performance to be monitored and any necessary repairs or remedial actions to be taken.

Surface contamination and physical damage

PV modules can become dirty or contaminated over time and this can reduce the operational efficiency and system performance. Similarly, exposure to the elements can result in physical damage to the component parts of a PV installation. Objects dropped by birds can result in physical damage to PV modules which may result in reduced output performance. Periodic electrical testing as part of regular maintenance will enable any problems to be identified and diagnosed.

Damage to wiring

The most obvious example of bad wiring is when wires hang below the panels and touch the roof or underlying vegetation. Eventually the wire coating will wear or be damaged by rodents and potentially expose the copper wires, presenting a shock hazard. Any deterioration of cable connections and wiring can be identified by applying regular electrical testing to identify potential faults.

Verification of system performance

The installation of solar PV systems is only undertaken after careful consideration of the costs involved and the potential return on investment provided by lower energy bills and FiT payments.As a result, the verification of system performance and energy output from the panels is particularly important. In many cases simple electrical faults or wiring failures can cause a serious inefficiency in the ability of the panel to produce power. Although proper metering will give an indication of system performance, periodic electrical testing is vital to verify ongoing functional performance over extended periods.

Warranty fulfilment

Periodic electrical testing of solar PV systems to identify and confirm continued safe operation and maximum energy output performance can be required as part of product warranties and PV system component guarantees.

Customer documentation

All solar PV installations require the provision of various documentation and forms to the customer. System documentation usually includes system data, installer details, electrical diagrams, operation and maintenance instructions and other information that may be required by certain standards or regulatory bodies .Copies of all test and commissioning data should also be provided and as a minimum this should include the results from the electrical safety and verification tests undertaken as part of the system installation procedures.

Insurance

Many insurance companies now require all Solar installations to be regularly maintained in order to comply with the policy terms of insurance. This becomes especially applicable in commercial installations but is becoming increasingly relevant in the domestic arena. Failure to comply renders all policies null and void.
