Commercial Grid Connect Solar Power Systems

Reducing power bills should be something we all strive for, New Zealand’s power prices are one of the highest in the developed world; the madness needs to stop.

So how can you reduce carbon emissions for your office, farm shed, or your place of business?  Solar power provides a viable option for many businesses, it’s sustainable and very easy to maintain.

A commercial solar power system in New Zealand is generally defined as a solar panel array larger than 10kW.  Examples of commercial operations that might consider installing solar power:

  • Convenience stores (dairy's, liquor stores, grocery stores)
  • Restaurants / cafes
  • Hotels
  • Vineyards
  • Shopping malls
  • Factories
  • Solar farms (solar panels in a large field that can power local communities)

Installing solar power for a business has obvious environmental benefits, but the financial benefits can be particularly attractive as solar power is produced during the day, between 9am and 5pm, the time when most businesses are using a lot of power.  

Using your own solar power as it is created will help off-set expensive electricity brought from the grid.

There are so many variables in a commercial environment that can affect your business, but having fixed electricity prices (via solar power) is one way to reduce uncertainty around electricity bills.  Solar power helps to protect your bottom line.

Our residential solar power pages has all the information we think you need to know that also applies to commercial solar power systems. From how a grid-connect solar power system works, solar battery storage, and how to choose the best solar panels.

Getting Quotes For A Commercial System

It is important to select the right solar power company, for two main reasons.  

Firstly, ensure you get the right system design -  If the system is oversized you will be sending a large portion of solar power to the grid, receiving a low buy back rates from an electricity company could significantly diminish your returns .  

The second reason is quality - Solar panels are expected to last over 25 years. Quality components alongside quality workmanship will provide a system that can thrive and continue to provide free power for many years.
