Additional information

What will it provide?
This system will provide you with over 80 kW hours per day. This is generally considered enough for a small business or large, power-hungry household. For Regional areas we can use a local Clean Energy Council Certified electrician, some delivery costs may be incurred for longer distances.

When will it pay for itself?
With this amazing price, your Dollar Solar system will have paid back the $11990* initial investment in energy bill savings in approximately 2.25 years!

When will I pay?
Just repeating, we do not ask you to sign a contract. Nor do we ask you for a deposit. You simply pay the installer when the job is done.
