Lower grid purchases
Size generation against consumption and load timing, not an arbitrary package headline.
HOME SOLAR / CUSTOMER GUIDE
Use the roof to buy
less electricity.
A good solar system is not a panel count. It is a site-specific plan for when you use power, how much roof is genuinely usable, what the network permits and whether a battery or EV is likely later.

WHAT CHANGES FOR YOU
The practical value.
A roof-aware design
Account for usable area, shade, orientation, access, aesthetics and future service work.
Keep storage options open
Avoid product decisions that make a later battery, backup or EV upgrade unnecessarily difficult.
YOUR OPTIONS
Compare the paths.
Solar now
Strong daytime use, a viable roof and a goal to lower imported energy.
CHECK BEFORE COMMITTINGExport limits, low daytime demand and switchboard scope.
Solar + battery
Evening use, time-of-use pricing, backup priorities or low-value exports.
CHECK BEFORE COMMITTINGUsable capacity, discharge power, gateway scope and payback assumptions.
Prepare for later
Budget or timing favours solar first but storage or EV charging is likely.
CHECK BEFORE COMMITTINGController compatibility, metering and room around the switchboard.
BEFORE YOU DECIDE
Get the variables clear.
What could I save?
Savings depend on usable generation, self-consumption, tariff, exports and future load. Nexen shows the assumptions rather than promising a generic percentage.
What will it cost?
Installed price changes with system size, hardware, roof access, switchboard work and network requirements. A final price follows site verification.
Should I oversize?
Sometimes—especially if a battery, EV or electrification is planned—but only within roof, inverter, network and budget constraints.

QUESTIONS & ANSWERS
The details that matter.
How many panels do I need?
The useful answer comes from annual consumption, daytime use, roof geometry, panel wattage and network limits. Nexen models a starting range, then verifies it on site.
Do premium panels automatically mean higher savings?
Not automatically. Module performance, layout, shade, inverter behaviour, installation quality and how much solar you use all affect the outcome.
What happens after I submit?
Nexen acknowledges the enquiry, checks the brief, identifies missing information and explains the next assessment step. Submitting does not approve finance, lock a rebate or commit you to buy.
