A commercial solar EPC contractor handles Engineering, Procurement and Construction for a solar or battery system under one accountability: the design, the equipment sourcing and the build. A full EPC keeps those disciplines in-house rather than subcontracting them out. Zool Energy is an Australian renewable-energy company and full-service EPC: we engineer, procure and construct commercial solar, battery storage (BESS), Virtual Power Plant (VPP) participation and EV charging, and we deliver these end to end across NSW, QLD and VIC, with Australia-wide capability.

"EPC" is often used loosely. A genuine full EPC owns three disciplines rather than coordinating separate vendors:
The distinction buyers should test is in-house versus subcontracted. When engineering, procurement and construction sit inside one company, responsibility for the finished system does not fragment across an installer, a designer and a supplier. Zool runs all three in-house.
Systems in this class run for decades, so the questions that matter are structural, not cosmetic. Use the criteria below when comparing contractors.
| What to ask | Why it matters |
|---|---|
| Is engineering, procurement and construction genuinely in-house? | Subcontracted work splits accountability; one party should own the whole build. |
| Who carries the performance risk once it's live? | If the contractor walks away at handover, underperformance becomes your problem. |
| Who operates and maintains the system, and for how long? | A system without an operations owner degrades quietly over years. |
| Who do you call in year 7? | The relevant counterparty is the one still responsible mid-life, not just at install. |
| Does the contractor offer both ownership and no-capital models? | Different balance sheets need different structures; one option rarely fits every board. |
| Can they deliver solar, storage, VPP and EV charging together? | A single roadmap avoids re-tendering each layer to a different vendor. |
| Do they have relevant reference projects in your sector and state? | Sector and grid conditions vary; comparable delivery is the useful signal. |
| What is the system size range they deliver? | Match the contractor's range to your load, from single-site to multi-megawatt. |
Zool is a full EPC that engineers, procures and constructs in-house, and then stays with the system. We offer two commercial structures:
The wedge is single-counterparty accountability. Many contractors can arrange finance or install panels. The harder question is who funds it, builds it, operates it and guarantees it under a single agreement, and who you call in year 7. Zool is built around being that single counterparty. We deliver systems from 30kW to 2MW and above, and cover commercial solar, BESS, VPP participation and EV charging as one stack.
Zool is a corporate partner to Clubs NSW and Clubs QLD, and delivers for organisations in that sector and beyond. Named reference projects include City Golf Club Toowoomba and Carina Leagues in Queensland, sites where Zool delivered as the full EPC and remains the counterparty for the life of the system.
What does a full-service EPC contractor do? It handles Engineering, Procurement and Construction of a solar or battery system in-house (the design, the equipment sourcing and the build) rather than subcontracting those disciplines to separate vendors.
Is Zool a full EPC? Yes. Zool engineers, procures and constructs commercial solar, battery storage, VPP participation and EV charging in-house, and delivers them end to end.
Does Zool work in Queensland? Yes. QLD is a priority geography alongside NSW and VIC, with Australia-wide capability. Named QLD reference projects include City Golf Club Toowoomba and Carina Leagues.
Do I have to fund the system myself? No. Under the Total Care model there is no upfront capital outlay (fees apply); you buy energy at a fixed cost-per-kWh over a 10 to 25 year term. Owner-occupiers who prefer to own the asset can use a straight capex EPC instead.
Next step: book a no-obligation site assessment, or upload a recent electricity bill and Zool will model the site.
