How Much Does a Solar System Actually Cost?
How much does a solar system cost? It is one of the first questions most homeowners ask when looking into solar. At Platinum Energy Group, the cost depends on the size of the system, your energy usage, your roof space and the details of the installation. As a rough guide:
– a 6.6kW solar system starts from around $5,000
– a 10kW system starts from around $7,500,
– a 13kW system starts from around $10,000.
How much does a solar system cost? These figures are general estimates only. Every home and every job is different, so the final price can vary depending on access, switchboard requirements, roof layout and how much power your household uses.
System Size Plays a Big Role
One of the biggest factors is the size of the system you need. Smaller households with lower usage may only need a 6.6kW system, while larger homes with higher power demand may benefit from a 10kW or 13kW system. A bigger system usually costs more upfront, but it can also generate more power and deliver greater long term savings.
Choosing the right size matters because a system that is too small may not offset enough of your electricity bills, while a system that is too large may not be the best fit for your budget. You can learn more about our solar panel installation Wollongong service here.
What Affects the Final Price
How much does a solar system cost? The final price is influenced by more than just the number of panels. Roof shape, roof pitch, panel layout, installation access, electrical upgrades and the condition of your existing switchboard can all affect the total cost. Homes with more complex layouts or additional electrical work needed may cost more than a standard installation.
