Why businesses electrify
Solar and storage are a good start. Moving vehicles and equipment off gas and other fossil fuels adds to the benefit.
- Lower running costs: heat pumps, induction equipment and EVs are more efficient than gas or diesel, and solar and batteries cut the bill further.
- A safer workplace: removing combustion from the building lowers fire risk, removes the chance of a gas leak and cleans up indoor air.
- More control: less reliance on the grid means less exposure to gas prices, fuel supply disruptions and peak demand charges.
- Better equipment: electric gear often responds faster, holds temperature more precisely and runs more quietly.
- Customer expectations: more customers, large corporates especially, prefer suppliers with low-carbon operations.

Common questions
Who installs commercial solar in Adelaide?
Westside Energy does. We work with hotels, holiday parks, councils and farms across South Australia.
What does commercial solar cost?
It depends on the size of the system and how your site uses power. We look at your site and your energy use before we quote.
Is battery storage worth it for a business?
It can be, particularly where peak demand charges are a large part of the bill. The answer depends on how your site uses power through the day.
Are there rebates for business installs?
Grants, rebates and tax treatment change and depend on the business. We can talk through what may apply, and your accountant should confirm the tax side.
