Are you looking for ways to save on your electricity bills? There’s plenty of advice out there from numerous sources on how you can save money on your power bill.

From being more diligent with appliance use to turning off the lights more often to closing the curtains at sunset, there are many ways that Kiwis can work on reducing their power bill. But what about making money back from your electricity company? By generating your own renewable energy - there might be an opportunity to sell your excess generation! You get to generate your own clean electricity through solar panels, and have the option to sell any excess energy that you haven’t used back to your power retailer.

Solar energy, right now, is one of the most promising clean energy options for New Zealand homes and businesses. As well as having a better impact on the environment, solar energy is an excellent way to help reduce your power costs. Let’s talk about solar energy and why selling power back to the grid can help benefit you and your family.

How solar works

While solar energy has been around for over 150 years, the technology used to harness the energy continues to develop faster than ever. Solar energy has gained popularity worldwide in the past decade, with many homeowners and business owners taking advantage of this free, renewable and clean source of energy. So how exactly does solar work? Solar panels generate electricity by allows photons - or particles of light - to knock electrons free from atoms.

This generates a flow of electricity. Simply put, the solar panel’s photovoltaic cells convert energy in the sunlight into electricity. Solar energy systems are now in great demand across the country - they have actually been known to increase a property’s market value!


How to sell solar energy back to the grid

Selling solar energy back to the grid - also known as a buy-back tariff - can be a great source of additional income.

Firstly though, it’s important to make sure that you’re generating more energy than you’re using. Study your latest electricity bills to determine your average use. Not all electricity companies offer buy-back tariff, so check with your current provider as to whether they have this option available. If not, you may want to consider switching electricity providers to one that does.

You’ll need to ensure that all electricity you generate is properly modified and controlled for supply to the national grid. This is through your local lines company and must be done by an approved meter contractor. Lastly, you’ll need a special meter which measures net electricity generated, which can generally be supplied and installed by your electricity provider.

How much can you make selling solar energy back to the grid?

In New Zealand, there are no regulations for setting the value of the excess energy you produce, or the minimum buyback rate you’ll receive. The terms and rates of the buyback rates will completely depend on your own power retailer. 

There are only a handful of New Zealand power retailers that buy energy back from their customers. These retailers include:

1. Contact Energy
2. Trust Power
3. Mercury
4. PowerShop
5. Meridian
6. Genesis
7. Nova Energy
8. Ecotricity
9. P2 Power.

Currently, the average buyback rates range from 7 cents to 16 cents per kWh. It’s definitely worth checking what your preferred power provider will offer and shop around for the best buy back rates.

Is it worth getting solar power?

Over 20,000 properties throughout New Zealand are now taking advantage of solar power systems - and this rate continues to increase.

It’s easy to see why so many Kiwis have switched to solar power energy, as it comes with many benefits.  Not only does solar power give you the ability to sell unused power back to the grid, you’ll be saving money on your monthly bill by using less power from the electricity grid.

While saving money on power would sound great to any homeowner, it’s important to account for the initial set up costs of your solar power system. As solar panels are not mass produced as of yet, the cost of the product and installation can be expensive. Be sure to not only budget for this, but to shop around and ensure you get the most competitive quotes.

Both the highlighted deals i clicked through to get turned out to be inaccurate speeds. Glimp saying 300/100 both providers only offering 100/20 for the price given, despite giving the same address in both sites. still giving 3 stars though as regardless the deals through Glimp are better than the standard advertised deals on the providers site.

Sign up didn't go quite the way it was meant to. But Kate called and she walked through everything so we could work out what went wrong. she was patient, friendly, supportive and kept me calm to finally get plan registration sorted ( still can't log in though - she must be magic )
