Questions
What solar system size do I need?
System size depends on your energy usage patterns and roof space. We analyze your bills and consumption patterns to recommend optimal configurations ranging from 5kW to 20kW+ systems.
How long does installation take?
Most residential installations complete within 1-2 days. Commercial projects typically take 3-5 business days depending on system complexity and site requirements.
Do you handle council approvals?
Yes, we manage all necessary paperwork including council permits, grid connection applications, and STC rebate submissions as part of our installation service.
What happens during blackouts?
Grid-connected systems automatically shut down during outages for safety. Battery-equipped systems can maintain power to essential circuits during grid failures.
Can I expand my system later?
Our systems are designed for scalability. Most installations allow adding panels or batteries within the original system's capacity limits.
How do I monitor performance?
We provide remote monitoring with mobile apps and web portals showing real-time production data, system health alerts, and monthly performance reports.
