Daytime load
Operating hours, interval data and seasonal demand show how much solar the site can use directly.
Commercial solar
Turn daytime demand into an advantage.
Commercial solar works best when the array, operating profile and site constraints are considered together. We help define the practical system—not just a panel count.
Roof and site
Available area, structure, access, shading, roof condition and cable routes all affect the practical layout.
Network and export
Connection limits and export settings need to be understood before the system size is finalised.
Future demand
EV charging, machinery, electrification and business growth should be considered before equipment is selected.
FROM DATA TO HANDOVER
A practical project pathway.
Commercial work needs clear responsibilities and site coordination. We define the scope, work with the relevant design and supply partners, and complete the electrical installation through Grenz Electrical.

SUITED TO THE SITE
Commercial and rural applications.
The same design logic applies across different properties: understand the load, use the available space well and make the installation maintainable.
Warehouses & workshops
Large roof areas and steady weekday loads can create a strong match for solar generation.
Retail & offices
Daytime cooling, lighting and equipment loads can often align well with production.
Farms & rural sites
Pumps, refrigeration, workshops, homes and resilience requirements need to be considered together.
Battery & backup projects
Storage may support resilience, load management or a specific operational need where the numbers justify it.

COMMERCIAL QUESTIONS
Important points to resolve early.
Answers depend on the site and network connection, so these begin the conversation.
Can solar be installed without stopping operations?+
Much of the work can often be planned around normal operations, but final connections or switchboard work may require a controlled shutdown. We identify this during planning.
Do we need a battery?+
Not automatically. A strong daytime load may already use a large portion of solar directly. Storage needs a specific operational or financial reason.
Can you work with our consultant or supplier?+
Yes. Grenz Electrical regularly partners with New Zealand design and supply businesses and can work within an agreed project scope.
What documentation is provided?+
The exact pack depends on the project, but handover includes the relevant testing, commissioning, electrical certification and system documentation.
