System size and energy goals
Panel count and nominal DC capacity are designed around electricity use, usable roof area and future battery or EV charging plans.

Solar Panel Cost in Adelaide
A solar quote is more than a panel price. The system size, roof layout, panel and inverter selection, electrical work, access and site conditions all affect the installed scope.
What affects the decision
Start With the Property, Not a Headline Price
PDG Energy does not publish a one-size-fits-all solar price because a like-for-like comparison needs the complete installed scope. A written proposal identifies the selected equipment, nominal DC capacity, roof layout, installation inclusions, exclusions and applicable conditions.
Quote factors
What the Assessment Needs to Cover
These factors help make quotes comparable. The applicable detail depends on your property and selected system.
Roof layout and access
Orientation, shading, roof material, pitch, working access, cable route and safety requirements affect the installation design.
Panels, inverter and monitoring
The selected panel model, inverter, monitoring and mounting system need to suit the final electrical and roof design.
Electrical and network requirements
Switchboard work, phase, metering, export conditions and distributor requirements are checked before the scope is finalised.

Questions to Ask Before You Decide
For a confirmed scope, move from this guide to the relevant core installation service.
Why do solar quotes vary?
System capacity alone does not define the installed scope. Roof layout, selected equipment, access, electrical work, inverter design and site requirements all affect the proposal.
Can I compare solar quotes by panel wattage?
Compare the complete design: exact panel and inverter model, panel count, nominal DC capacity, roof layout, electrical work, monitoring, workmanship terms, inclusions and exclusions.
Will a larger solar system always be better?
Not necessarily. The practical system size depends on usable roof area, electricity use, daytime consumption, export conditions and future loads.
