We Supply & Install Solar Power Systems in Christchurch & Canterbury…

Add a solar power system to your Christchurch home now and you’ll have an investment that pays dividends for years and years to come. A solar power system allows you to tap into power generated by the sun every day.  This reduces your monthly power bills and your reliance on power from the national grid.  You’ll save even more while power retailers’ prices continue to increase.

What is a PV Solar Power System?

A solar system typically includes solar panels connected to an inverter.  The inverter has a few important jobs.  It turns DC power from the panels in AC power that we use in our homes and workplaces. It also synchronises the AC power with national grid so that you can export any spare power you make back to the grid.  The inverter also contains a number of very important electrical safety features.

During a solar installation, we will install the solar panels and electrical wiring to the inverter and your switchboard.

Approvals & Inspections

As part of our installation for a solar system in Christchurch or Canterbury, we arrange the necessary approvals and inspections:

  • Distributed generation (DG) approval required from the electricity network provider.  This is Orion for solar systems in Christchurch and the Selwyn District.
  • Arrange for export meter installation with your power retailer
  • Electrical Certificate of Compliance (COC) from one of our Registered Electricians
  • Electrical Inspection and Record of Inspection (ROI) document from an Electrical Inspector

Solar systems are amazing when they are well designed and installed.  We’d love to help with your Solar Power in Christchurch, Rolleston, Darfield or Methven, so please give us a call, email us or fill out the form on this page.

PV Solar Power Explained…

There are three common types of solar power setups that are used in homes and businesses in New Zealand.  Which one is best suited for you will depend on a few factors.  Our team can help explain these to you in easy to understand language.

Grid Tied Inverter

Hybrid Inverter & Battery

Off-Grid Inverter & Battery

PV Solar Panels Generate Power and send it to the…

Grid Tied Inverter
  • Converts power to AC
  • Building uses as much solar power as it can
  • Exports extra power to the National Grid, you get a power credit as a result

Benefits

  • Exports excess power to the grid

Downsides

  • Can only use the solar power as it is generated while the sun is shining
  • In a power cut, your solar power will stop working too

PV Solar Panels Generate Power and send it to the…

Hybrid Solar Power Inverter
  • Converts power to AC
  • Building uses as much solar power as it can
  • Sends excess DC power to the solar system batteries
  • When batteries are full, exports excess power as AC to the National Grid
  • When there is a power cut, the system runs “essential” power circuits so you have lights and power for internet and phone charging for example.  Possibly even the fridge!
Solar System Batteries
  • DC power is stored in the batteries
  • The power is sent back the inverter for use when the panels aren’t producing enough power for the building’s needs

Benefits

  • Uses solar generated power at night from the batteries
  • Exports excess power to the National Grid
  • Lastly, the system still works during a power cut to run “essential” power circuits

Downsides

  • Large battery banks can be tough on budgets!

PV Solar Panels Generate Power and send it to the…

Off-Grid Charge Controller & Inverter
  • Charge controller sends excess DC power to the solar system batteries
  • Inverter converts power to AC
  • This system is NOT connected to the National Grid
Solar System Batteries
  • DC power is stored in the batteries
  • The power is sent back the inverter for use when the panels aren’t producing enough for the building’s needs

Benefits

  • Uses solar generated power at night from the batteries
  • Comparatively cost effective solution for new homes a long way from a National Grid power connection

Downsides

  • Once the battery is empty at night, then you get a “power cut” till the sun comes out again.
