How much of your electricity spend could solar replace?
Your electricity spend is the starting point. Crown Technologies assesses how your business uses power, then recommends a solar system with estimated savings based on your site. Need backup too? Battery options can be matched to the equipment you need to keep running.

Your electricity account deserves a closer look
Electricity costs take a bite out of your operating budget every month. Understanding how much power your site uses, and when it uses it, is the starting point for assessing what solar could change.
The right system starts with your electricity account and the way your business operates.

Where the savings come from
Peak demand tariffs
When your site draws the most power shapes what you pay.
Daytime operational load
The hours your equipment runs determine how much solar can offset.
Year-on-year rate rises
Tariffs climb each year. A system is sized against that trend.

Crown assesses your electricity use and site requirements to recommend a suitable FOX ESS configuration. Your proposal should make the equipment, costs and estimated savings clear, with the assumptions behind those estimates.
- Equipment specification and FOX ESS configuration
- Cost and estimated savings breakdown
- Documented assumptions behind the estimates

Why Crown Technologies chooses FoxESS solar
Backup Planning
What your backup system is built around
Tap a load to shed it during an outage
What must keep running
Site audit · Crown walks the site to identify the equipment that must stay live during an outage — fridges, servers, security, lighting, pumps — and records each circuit at the distribution board.
Required runtime hours
Site audit · We confirm how long each essential load needs to keep running without grid power, from short bridging minutes through to extended outage windows, so the battery is sized to the real requirement.
Matched to critical loads
Site audit · The connected essential loads and required runtime set the usable capacity. Crown measures the draw of the backed-up circuits and matches a battery bank to that load profile.
Tailored to site DB
Site audit · Every site's distribution board is different. Crown assesses the board layout, available space, and integration points so the backup system connects cleanly to your existing installation.
Plan for power interruptions, too
If your business also needs backup power, identify the equipment that needs to keep running and for how long. Crown Technologies can assess battery options around those requirements.
Backup capability depends on the system configuration, battery capacity and connected equipment.

Your potential savings depend on how much electricity you use, when you use it, your tariff and the proposed system. Crown needs to assess those details before providing a site-specific estimate.
A recent electricity account is a useful starting point. Crown may request more usage history to assess your site properly. You can still chat to Alex before you have those details ready.
No. Start with your site and backup requirements. Crown can assess which configuration suits your operation.
Crown offers different support arrangements. Maintenance and monitoring are available under separate agreements, so confirm the scope in your proposal.
That depends on the system configuration. Backup requires equipment designed for that purpose, with battery capacity matched to the connected loads and the duration you need. Confirm what the proposed system will support.
Yes. Crown Technologies works with residential as well as commercial and industrial sites.
Yes. Finance options are available. We go through them with you as part of your proposal.
