Commercial solar panels engineered for Australian roofs.
Comstel Energy designs and installs commercial-scale solar systems sized to your roof, your energy demand and your budget. Tier-1 panels only, CEC-accredited installation, 25-year performance warranty, and STC rebate handling — all included.
The business case is stronger than ever.
Australian commercial energy costs continue rising. Solar is one of the few capital investments that pays for itself, then continues paying for decades.
3-7 Year Payback
Most commercial systems pay for themselves within 3-7 years. After that, essentially free energy for 20+ more years.
STC Rebate
Federal Small-scale Technology Certificates reduce upfront cost on systems up to 100kW. Comstel handles the paperwork.
Daylight Match
Most businesses use the most power during sunlight hours — exactly when solar generates the most. Excellent self-consumption.
Scope-2 Reduction
Cuts electricity-sourced emissions immediately. Helps with ESG reporting, tender requirements, NABERS ratings.
Property Value
Commercial properties with solar attract higher rents and resale values. Increasingly required by tenants.
Energy Independence
Reduce exposure to grid price spikes. Lock in your energy cost for the next 25 years.

Six things to understand about commercial solar.
Solar is a 25-year decision. These are the topics that determine whether the system will deliver — talk to us about the specifics for your site.
Why Manufacturer Choice Matters
Solar warranties only matter if the manufacturer still exists in 25 years. Tier-1 status (Bloomberg NEF classification) separates the bankable from the rest.
- Bankable warranty
- Financial strength rated
- Project track record
- Lender-accepted brands
More kW from Same Roof
Modern modules deliver 20-23% efficiency. Critical when roof space is limited or you want to maximise generation per m².
- 20-23% modern efficiency
- Half-cell & bifacial options
- TOPCon / HJT technologies
- Higher yield per m²
25-Year Linear Performance
Quality commercial panels guarantee 87-88% of original output at year 25. We only install panels with linear performance warranties.
- 25-yr linear performance
- 12-15 yr product warranty
- Tier-1 brands only
- CEC-approved list
Built for Our Climate
Australian conditions are harsh — high UV, heat, salt-spray (coastal), hail and cyclones. We specify panels rated for these specific stresses.
- High-temp coefficient
- Salt-spray rated (coastal)
- Hail-impact tested
- Cyclone-zone mounting
How It Reduces Cost
Federal Small-scale Technology Certificates reduce upfront cost on systems up to 100kW. The rebate is worth thousands — Comstel handles the paperwork.
- Federal incentive
- Systems up to 100kW
- Calculated automatically
- Comstel files paperwork
