Receiving several commercial solar proposals can be helpful, but it can also make the decision more complicated.
One proposal may offer a larger system, another may recommend different equipment, and a third may have a lower upfront price.
So, how should a business decide?
The answer is to compare the complete solution, rather than focusing on one number.
Start With Your Business's Energy Usage
Before comparing proposals, understand how your business uses electricity. Look at:
- Average electricity consumption
- Operating hours
- Peak energy demand
- Seasonal usage
- Expected changes in energy consumption
A commercial solar system should be designed around the way your business operates.
Compare the Recommended System Size
Different retailers may recommend different system capacities for the same property. Don’t automatically assume that the largest system is the best option.
Ask:
- Why was this system size recommended?
- Does it match our electricity consumption?
- How much suitable roof space is available?
- Can the system accommodate future needs?
Understanding the reasoning behind each proposal makes comparison easier.
Look at the Equipment
The equipment included in each proposal can have a significant impact on the overall value of the system.
Compare:
- Solar panel specifications
- Inverter capacity and specifications
- Monitoring capabilities
- Battery compatibility
- Product warranties
The goal isn’t necessarily to choose the most expensive products. It is to understand what each proposal offers and whether the equipment suits your business.
Check What the Price Includes
A lower price can sometimes reflect a different scope of work.
Before comparing totals, check whether each proposal includes:
- Installation
- Electrical work
- Required upgrades
- Commissioning
- Monitoring setup
- Warranty support
This helps ensure you’re comparing like-for-like proposals.
Consider Your Business's Future
Your current energy consumption may not remain the same.
You could be planning:
- Business expansion
- New machinery or equipment
- Longer operating hours
- Electric vehicle charging
- Battery storage
A proposal that allows for future changes may offer greater flexibility as your business develops.
Compare the Overall Value
When reviewing proposals, consider more than the upfront price.
A useful comparison includes:
System design + equipment + installation + warranties + future flexibility + cost This gives you a clearer understanding of what each proposal actually offers.
Ask Why the Proposals Are Different
If three businesses recommend three different systems, don’t simply choose the cheapest one. Ask each provider to explain:
- Why they selected the system size
- Why particular products were recommended
- What is included in the installation
- How the system supports your business’s future needs
These answers can reveal important differences that aren’t obvious from the quote alone.
The Bottom Line
Choosing between commercial solar proposals is about finding the right fit for your business, not simply selecting the lowest price.
By comparing energy requirements, system size, equipment, installation inclusions, warranties and future flexibility, Victorian businesses can make a more informed decision.
Taking the time to compare proposals properly can help ensure your commercial solar investment supports your business for years to come.
