The ideal solar system size for your Colley home depends on your daily electricity consumption, available roof space, and energy goals. The key is matching your system size to your actual usage patterns to maximize savings without oversizing unnecessarily.

How to determine your needs: Check your recent electricity bills to find your daily kilowatt-hour (kWh) usage. In Colley, average households use 18-25 kWh/day, though this varies significantly based on home size, appliances, and lifestyle.

Why 6.6kW is most popular in Colley: The 6.6kW system (with a 5kW inverter) represents the sweet spot for most households. It's the maximum size eligible for standard single-phase connection in Australia, offers excellent cost-per-watt value, fits on most residential roofs (requiring approximately 33-40m² of suitable north-facing or west-facing roof space), and typically generates 10,660 kWh annually in Colley—enough to cover 70-100% of average household consumption.

Planning for the future: Consider sizing slightly larger if you're planning to purchase an electric vehicle, install a pool, or work from home more frequently. Colley homes with EVs typically benefit from 8-10kW systems. Conversely, if you're rarely home during the day and don't have a battery, a smaller 4-5kW system might be more cost-effective.

Expert tip for Colley: During your free quote consultation, ask installers to review your recent bills and recommend a system size based on your actual consumption patterns rather than just household size. The best installers in Colley will use professional software to model your specific energy usage and roof characteristics for optimal system design.
