Can you go off-grid with solar power?

Living off-grid – that is, living independently of the main grid, big power companies and big power bills – can seem very appealing when you consider ever-increasing electricity costs.

There are some areas which through lack of choice have to be off grid. Traditionally, gas or diesel has powered generators for these areas.

But for many people, going off-grid is a recurring pipe-dream, not something to be considered a real possibility.

However, things are changing: off-grid living is now within the reach of many Aussies.

Why consider going off-grid?

When you go off-grid you eliminate electricity bills. Even if you reduce your power usage, when connected about three-quarters of your bills are network and generation costs.

Living off-grid however means you can avoid both the network and usage costs of electricity.

You can protect yourself from power outages and blackouts when you’re off-grid. Unplanned outages in particular can really mess up your day, especially considering you have no control over when the power comes back on. With an off-grid system this is something you don’t need to worry about.

Go off grid: Costs down, emissions down

You reduce your carbon emissions and footprint when off-grid. Setting up your own clean energy generation enables you to contribute towards the reduction of emissions. It means you can do your bit for climate change, which according to research is important to most Australians.

You can also remove upfront connection costs. In some rural regions where there are no nearby power lines, grid-connections can cost tens of thousands of dollars. An off-grid system can provide a viable alternative and eliminate ongoing costs as well.

How to go off-grid with solar and energy storage

A solar installation enables you to generate your own clean power and reduce your bills. In saying that however, you may have heard it said that it’s not possible to go off-grid with solar power because the sun isn’t always shining.

However, with an energy storage solution along with your solar installation you have the best of both worlds – electricity generation and excess storage for later use. This means that instead of wasting any unused solar power you can’t use immediately, you can store it away for use in the evenings or on dull days.

Energy storage examples:

  • Tesla Powerwall 2 – the lithium-ion Powerwall 2 comes with a 10-year guarantee. The battery allows you to store up to 13.5 kWh of solar energy to use when you need it.
  • Enphase modular systems – modular Enphase batteries are smaller than the Powerwall, but their flexibility means you can add more storage as you need it. Enphase batteries also come with a 10-year guarantee.

Meanwhile, the cost of solar panels and energy storage batteries is falling all the time. These systems are also becoming more efficient with better technologies. Combined, these factors mean going off-grid is becoming a possibility for households and small businesses.
