FAQs

Frequently Asked Questions

Common questions about off-grid solar systems and energy independence

How much does an off-grid solar system cost?

Off-grid solar systems typically range from $20,000 to $100,000+ depending on your energy requirements, battery capacity, and backup systems needed. Our consultation includes a detailed assessment of your needs and a customised quote for your specific situation.

How much battery storage do I need?

Battery storage requirements depend on your daily energy usage and how many days of autonomy you need without solar production. Most residential off-grid systems require 20-40kWh of storage for 2-3 days of backup power. Our energy assessment helps determine your exact requirements.

Do I need a backup generator with my off-grid system?

While not absolutely required, we generally recommend a backup generator for most off-grid systems. This provides redundancy during extended periods of low solar production, extreme weather events, or unexpected high energy usage. We can integrate a generator that automatically starts when battery levels drop below a set point.

Can I run all my normal appliances with an off-grid system?

Yes, a properly sized off-grid system can power all standard home appliances. However, energy-efficient appliances are recommended to maximise your system's capacity. High-draw items like electric heating, air conditioning, and pool pumps require careful consideration and may need larger system capacity.

What maintenance is required for off-grid solar systems?

Off-grid systems require more maintenance than grid-tied systems. Routine tasks include battery monitoring, occasional equalization charging for certain battery types, generator maintenance, and system inspections. We offer maintenance packages and remote monitoring to ensure optimal performance of your off-grid system.
