Frequently Asked Questions
How reliable are off-grid solar systems in bad weather?
Modern off-grid systems are highly reliable even in cloudy or rainy conditions — provided they’ve been properly designed. This typically involves adding battery storage that can carry the load through low-sunlight periods and incorporating a generator for extended cover. Energy monitoring can also help you manage loads during poor weather to avoid running short.
Can I run large appliances like ovens or washing machines off-grid?
Yes, but it requires correct system design. High-demand appliances like ovens, dryers or induction cooktops can place heavy loads on an off-grid system, particularly if used simultaneously.
Your installer needs to factor in these loads when sizing your inverter and batteries. In some cases, scheduling use or choosing energy-efficient models helps smooth overall performance.
How much space do I need for off-grid solar?
You’ll need roof or ground space for the solar panels, typically 20-30m² for an average system. Batteries and inverters are usually installed in a weather-protected shed, garage or purpose-built cabinet.
It doesn’t take up much space overall, but access, shade and airflow all factor into where equipment can go. Your installer will assess and recommend the best setup.
Off-Grid Solar That Keeps You Powered
Every install starts with understanding how you use energy — and when. That’s what shapes the design. From appliance loads and climate control to whether you use power early in the morning or long into the night, we build systems that work around your daily rhythm. In Caloundra, that means considering humidity, power security and space limitations, too.
We size your panels and battery storage accordingly, adding backup generation and smart monitoring where needed. Our setups are designed to grow with your property and your needs. We’ll walk you through the system before handover and keep things easy to manage long after install. It’s about control, clarity and a system you actually enjoy using.
