Solar Power Plans: What Deals are Power Companies Offering?

If you’re considering installing a solar system, it’s important to weigh up the solar plans available from the power companies in your area. Canstar Blue looks at what’s on offer.

Installing solar panels isn’t just about going green and saving on your power bill, they can also be a way to make money by selling excess energy back to the grid, commonly know as buy-back.

So, when running the numbers on solar’s suitability for your home, it’s important to factor in buy-back rates when determining whether solar is right for your household.

In the following guide, we take a look at what you should keep in mind when setting up solar, and some of the deals on offer from power companies.

Setting up solar: dealing with power companies

Of course, when assessing solar’s suitability for your household, it’s important to weigh up the short-term costs versus the potential long-term savings. Tools such as the Energy Efficiency and Conservation Authority’s solar tool, available here at the Gen Less website, a good starting point.

Almost all solar systems require installation by a licensed electrician or inspector, and it’s worthwhile shopping around to get a gauge on the types of deals being offered.

Power companies sometimes work in conjunction with solar installers. So getting in touch with different retailers in your area when seeking out an installer can be a good starting point.

Solar Power Is it Worth it

Most households that install a solar system will remain connected to the mains power grid. This is so they have a ready supply of power during times of high demand and at night.

If you plan on exporting excess electricity into the grid, you’ll need to arrange for your power company to install an import/export meter, capable of recording the import and export usage to the network.

When setting up your meter, it’s important to confirm:

  • How much the meter will cost to install
  • The tariff options available with the meter, including what you will pay for electricity and the buy-back rates on offer
  • Your contract length
  • Any limits on the size of your solar system. Often they are limited to under 10kW
