Melbourne averages approximately 4.0 peak sun hours per day across the year — enough for a well-designed solar system to generate significant savings. A standard 6.6kW system in Melbourne typically produces 24–26 kWh per day on average, which covers most of a typical household’s daily electricity consumption.
With Victorian electricity prices sitting above 30 cents per kWh (and rising), every kilowatt-hour your solar system generates is a kilowatt-hour you do not buy from the grid. Combined with feed-in tariffs for excess energy exported back to the grid, solar panels in Melbourne typically pay for themselves within 3–5 years.
Victorian homeowners also have access to some of the strongest solar rebates in the country, making the upfront cost significantly lower than the sticker price.
The right system size depends on your household electricity usage, roof space, budget and future plans (batteries, EV chargers, heat pump hot water).
These are indicative ranges. Zap Tech Energy provides a detailed site assessment and custom quote for every property — because roof orientation, shading, switchboard capacity and energy usage patterns all affect system design and pricing.
After rebates, a 6.6kW system typically costs $3,500–$5,500, a 10kW system $6,000–$9,000, and a 13kW+ system $8,000–$12,000. Exact pricing depends on panel and inverter selection, roof complexity, and switchboard requirements. Zap Tech Energy provides free, detailed quotes with no obligation.
Most residential solar installations are completed in a single day. Larger systems or properties requiring switchboard upgrades may take two days. Grid connection and retailer paperwork typically takes 1–4 weeks after installation.
Yes. Solar panels generate electricity from daylight, not direct sunshine. Melbourne's average of 4.0 peak sun hours per day is sufficient for strong system performance. Panels still produce power on overcast days — just at a reduced rate.
Most tier-one solar panels carry a 25-year performance warranty. Inverters typically carry a 10–15 year warranty depending on the model. With no moving parts, solar panels require minimal maintenance and often perform beyond their warranty period.
