22 Modules covered across all aspects of Commercial Solar.
What Greenwood has learnt in 10 years the hard way, we pass on to you.
The commercial solar industry is evolving fast - with new tech, shifting regs and increasing competition.
Master the latest technology, navigate complex commercial installs through real project examples.
Gain skills to quote, design and deliver projects with precision - help reduce risk to your business, by hearing first hand from Greenwood.
Create an early-stage estimate of the total project cost, based on initial site data, proposed system size, and component selection.
It’s essentially a ballpark financial snapshot to help stakeholders gauge interest.
The end-to-end workflow of designing, approving, and installing a solar energy system for a business or industrial site.
Think of it as the blueprint from concept to kilowatt and everything that goes on in between.
On-location inspection to gather critical data for designing a solar system, such as roof condition, shading, switchboard layout, and structural integrity.
It’s the boots-on-the-ground step that turns assumptions into facts, ensuring the system design is accurate, compliant, and install-ready.
The detailed client-facing document that outlines your final solar system design, costs, expected performance, warranties, and terms of agreement.
It’s the polished pitch that turns technical plans into a professional offer, ready for client sign-off and project green light.
Project management in solar involves coordinating all phases of the installation—from procurement and scheduling to compliance, logistics, and communication.
This ensures the system is delivered on time and within budget. It’s the behind-the-scenes engine keeping the whole show running smoothly, on time and on budget.
The collection and organisation of all required technical, regulatory, and project-related paperwork—like engineering designs, compliance forms, connection applications, and warranties.
It’s the paper trail that keeps your project traceable and ready for future servicing.
A step by step guide on pre - approvals through to engineering sign off and post install connection and DNSP approvals.
Without these steps being adhered to, you risk your new PV system not being accepted by the distributor.
-Or worse.
A solar system that cant be switched on.
The technical blueprint of your solar system, translating the concept into actionable construction plans with precision.
It includes electrical schematics, layout drawings, structural calculations, protection settings, and compliance docs.
Everything needed to build the system right the first time.
The brain of any solar system—it converts DC electricity from the panels into AC power that can be used onsite or exported to the grid.
Beyond conversion, it manages grid compliance, system monitoring, safety shutdowns, and sometimes even battery integration or export control - a critical choice for install.
Solar panels convert sunlight into DC electricity, and their efficiency, durability, and warranty directly impact system performance and ROI.
Rails and mounting equipment form the structural backbone, securing panels to rooftops in all weather conditions.
The safety device installed between the solar system and the grid.
Typically required for larger commercial systems. It provides extra layers of protection—like overvoltage, overcurrent, anti-islanding, and network monitoring—to ensure the system disconnects safely.
Learn about the commissioning process used to verify that the protection relays respond correctly to simulated fault conditions.
It ensures the system trips precisely as required by grid standards - making it a critical final step before grid connection on larger systems.
