How do I add solar panels to an existing renewable energy system?

As an existing renewable energy customer you may expand the number of panels connected to your existing inverter (provided your existing inverter can support this expansion) and continue to receive the buyback price and any net Feed-in Tariff (FiT) payments you currently receive.

You must apply to Horizon Power before carrying out the panel expansion. Please speak to a licensed and accredited installer to discuss your options.
