FAQ
Common questions.
What size solar or battery system do I need?
It depends on your roof space, energy usage and goals. We assess your site — whether it's a home, business or industrial facility — and recommend a system sized to suit, rather than a generic package.
Can I add a battery to my existing solar system?
In most cases, yes. We can assess your existing solar system and switchboard to determine the right battery-ready upgrade path.
How much can battery storage reduce my business's demand charges?
Savings depend on your site's usage patterns and peak-period demand. We review your energy usage as part of the assessment and provide a plan focused on reducing demand charges and peak-period costs.
Do you handle both the solar and the electrical/switchboard work?
Yes. As a licensed electrical contractor and CEC accredited installer, Diamper handles the solar installation and the electrical side — switchboard, safety and integration — with the same team.
Are you CEC accredited?
Yes, Diamper is a Clean Energy Council (CEC) accredited installer, a NECA member, and a licensed WA electrical & solar contractor (EC012908).
How long does installation take for a home vs a commercial or industrial site?
A domestic install is typically completed much faster than a commercial or industrial-scale project, which involves more scoping, estimating and commissioning. We'll give you a clear timeline as part of your quote.
Do you offer ongoing maintenance and monitoring?
Yes, we offer testing, maintenance, performance checks and system monitoring support after installation for domestic, commercial and industrial sites.
