Outline Summary
How much power does a 7.9kW solar system produce?
A 7.9 or 8kW solar system generates almost 23.7kWh (during winter) to 39.5kWh (during summer, bright sunny ☀️ days) electricity. There are multiple factors (e.g. roof structure, weather/temperature conditions) that may affect these units.
Below is the daily electricity production of a 7.9kW solar system per month.
Is 7.9kW (8kW) solar system with battery enough to run a house in Victoria?
The suitability of a 7.9kW solar system with a battery to run a house in Victoria for 4-5 people depends on several factors such as the energy consumption patterns of the household, the size of the house, and the efficiency of the appliances used.
In general, a 7.9 or 8kW solar system can generate a significant amount of electricity, especially during peak sunlight hours. The battery component can help store excess energy generated during the day for use during the night or periods of low sunlight. Consequently, such a system can be sufficient to power a house with 4-5 people 👍.

Why you should consider investing in a solar battery?
Solar batteries offer reliability by storing excess energy generated during the day, providing a backup power source during cloudy days or at night. They enhance savings by allowing homeowners to store excessive energy instead of selling it back to the grid at lower rates and avoiding peak hour charges. Additionally, solar batteries contribute to environmental sustainability by reducing reliance on fossil fuels and shrinking carbon footprints. Despite the upfront cost, investing in a solar battery provides a long-term, reliable, and sustainable energy solution, future-proofing against rising energy costs and grid failures.
