Solar Saving & Payback Calculator

See how long it will take for a solar system to pay for itself. The calculator also allows you to compare a high quality photovoltaic (PV) system with a lower priced solar system and see the difference in payback time.

What our Clients Say

I ended up looking into solar as an off grid solution when the price to get power to my house block was much more than expected. After doing some research and speaking to a few different solar providers I decided to go with Donnas Electrical. Hoping that by going local follow up service and quality of products would not be an issue, I had read plenty of horror stories. To be honest I could not be happier with my choice. Kane was able to supply a system to the budget I had in mind (which was quite a strict budget), on par with other quotes I had received and half that of getting the house connected to grid power. The installation was done to my time schedule and most importantly everything was very neat and tidy. Follow up service has been magnificent and I have no concerns that if I'm ever to have an issue they will be contactable. Every thing has worked exactly as it should and to the quality I expect. I would recommend dealing with the team at Donna's Electrical to anyone.

Having solar panels installed was definately the best investment I have ever made and getting the Tesla Battery was the icing on the cake.  Finally in credit, yay one happy customer!

Thank you to Kane and the team at Donnas Electrical for the supply and installation of our solar and battery at Bordertown.  Your service and communication from start to finish was fantastic.  Loved also that the person who quoted did the installation.
