Installation, maintenance and servicing
Installing solar the right way
A solar power system is electrical work, and WorkSafe recommends using a registered electrician to install one. Any system working above 50 volts AC or 120 volts ripple-free DC must be installed by a registered electrician.
Where installing a solar (photovoltaic) system is prescribed electrical work, as it is for any system above 50 volts AC or 120 volts ripple-free DC, it is high-risk prescribed electrical work under the Electricity (Safety) Regulations 2010. That means the installation has to be inspected by someone authorised to inspect high-risk work, and it is not complete until a certificate of compliance and a record of inspection have been issued for it. Your installer will usually arrange the inspection, and the inspector cannot be anyone who did, supervised or certified the work.
WorkSafe sets out what that means for anyone thinking of doing it themselves in its guidance on DIY solar installations.
Connecting solar to the grid in Morrinsville
If you connect solar panels to the grid to sell power back, you must comply with Part 6 of the Electricity Industry Participation Code, and your local lines company has to approve the connection under its own rules.
In Morrinsville the lines company is Powerco. For a solar connection Powerco asks the installer to submit a Distributed Generation connection application and, once the work is done, a copy of the certificate of compliance. Powerco approves an application only if the system uses an approved inverter. For a home system under 10 kW, the Energy Efficiency and Conservation Authority says approval generally takes one to two weeks.
The Electricity Authority notes that solar power systems typically do not need council consent, but suggests checking with your council or your solar installer. Its solar power guide explains the rules for connecting to the grid.
Looking after a solar system
Solar panels are built for a long life: if they are well maintained, the Energy Efficiency and Conservation Authority puts it at about 25 to 30 years. The inverter, which converts the panels' DC output to AC power, usually needs replacing sooner, after about 10 to 15 years.
For most homes, cleaning the panels every 12 months can be enough. Do not use hot water, pressure washers, abrasive brushes or steel wool on them.
If a solar system has a problem at any time, WorkSafe's advice is to turn the system off straight away and contact your electrician. Where changing a solar system's settings is prescribed electrical work, the Regulations class it as high-risk work, so it needs a registered electrician and the same inspection and certification as an installation.

Does my lines company need to approve a solar system?

For a home system under 10 kW, the Energy Efficiency and Conservation Authority says approval generally takes one to two weeks.
Does a solar installation have to be inspected?
Yes, if the work is prescribed electrical work, as it is for any system above 50 volts AC or 120 volts ripple-free DC. That makes it high-risk prescribed electrical work, so it must be inspected by someone authorised to inspect high-risk work, and it is not complete until a certificate of compliance and a record of inspection have been issued.
How often should solar panels be cleaned?
For most homes, cleaning the panels every 12 months can be enough. Do not use hot water, pressure washers, abrasive brushes or steel wool.
