Solar PV operation and maintenance services

Despite having no moving parts, a PV system needs to be inspected at regular intervals to ensure smooth operation. Generally this involves annual detailed visual inspection, cleaning and electrical testing.

An annual site inspection is included within NWT’s Operation & Maintenance package.  Any remedial repair works required to the PV installation, outside of product warranties, will incur additional costs for parts and labour.

See “Our Projects” for examples of the kind of issues we have encountered.

These include inverters that have cracked, loose connections that can have safety implications, incorrect terminations causing whole strings to be lost, vermin infestations and installations with no monitoring system (meaning there is no alert if a fault develops).  All of these issues have contributed to substantial and irrecoverable loss of income.
