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:
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.
