Choosing the Right Solar System Size for Commercial Installation
Commercial solar systems have become preferred for organisations in Australia because of increasing electricity prices and decreasing solar system expenses. They offer an exceptional opportunity to reduce costs and decrease ecological effects. Nonetheless, choosing the right commercial solar system takes a little bit of research and time. But we here are trying to make your job easy. This article will guide you in all the important things you should know when choosing the right solar system for your commercial solar installation.
Assess Your Energy Usage
Analyse Historical Energy Data
Review electricity bills over the past 12 months to understand your energy consumption patterns.
Peak Energy Demand Period
You should understand and examine your peak use hours and seasonal variants to identify how much solar power you need.
Future Needs
Consider service growth plans or added equipment that might increase energy requirements.
Business Operating Hours
Daytime Operations: Commercial solar systems are most helpful for businesses that operate throughout daytime hours, such as 9 a.m. to 5 p.m.
Determine Roof or Land Space Availability
- Space Assessment: Based on sunlight exposure and shading, decide whether to use roof space or vacant land. Professional assessments can help identify the most efficient solution for your business.
- Ground-Mount Options: If there is no sufficient roof available, ground-mounted systems can be mounted, but there should be adequate land.
Evaluate Financial Goals
- Budget: Decide how much you will invest upfront or through financing.
- Payback Period: Consider the payback period, usually 3–7 years, for most commercial systems.
Monitoring and Maintenance
- Regular monitoring and maintenance ensure optimal efficiency and durability. Expert help can help you track power intake and determine ways to enhance energy savings.
Financial Rebates

Choosing the Right Solar Power Brand
Trusted Brands
Go with trustworthy brands which are known for their long-term integrity.
Experience Matters
Brands with more than 10 years of experience are preferred.
Tier 1 Panels
Tier 1 solar panels are trustworthy for long-time service.

Here’s a quick guide to standard commercial solar system sizes:
System Size | Approx. Annual Output | Ideal For | Rooftop Area Required |
10 kW | 14,600–16,500 kWh | Small businesses with low energy needs | 60–80 m² |
30 kW | 43,800–49,500 kWh | Medium-sized businesses | 180–240 m² |
50 kW | 73,000–82,500 kWh | Businesses with moderate energy needs | 300–400 m² |
100 kW | 146,000–165,000 kWh | Large facilities or energy-intensive businesses | 600–800 m² |
250 kW | 365,000–412,500 kWh | Manufacturing units or multi-tenant commercial hubs | 1,500–2,000 m² |
Seek Professional Advice
- Energy Audit: Speak with solar providers for an in-depth power audit and personalised suggestions.
- Warranties and Support: Select a system with durable service warranties and good after-sales support for assurance.
