How Much Can You Save With Solar Panels in Adelaide?
Everyone’s talking about the cost of electricity these days. It’s no wonder, South Australia now has the highest energy prices nation-wide.
And with that, what’s recently become very popular is Solar Panels. Just about every discerning home owner would consider installing solar panels for their home in Adelaide. Knowing that Solar Panels could potentially reduce their electricity bills significantly if used the right way.
So how much can you really save with Solar Panels?
Solar Panels System Sizes
Solar Panels come in various system sizes. The size is measured in terms of it’s capacity and is rated in KWs. A larger KW system will deliver a higher daily yield, which is the amount of usable electricity that a solar panel system can generate each day. This is measured in kWh.
Solar Panel systems come in various system sizes. They start from 2KW – 3KW, and scale up to over 10KW. Often, the system size you can install is limited by the amount of space you have on your roof? Most averaged size homes can install up to 5-7KW with their available roof size. Larger homes can accomodate more panels – and hence support larger system sizes.
A single solar panel generates between 250-270W of power. So a 5KW system would comprise of between 18-20 solar panels.
How Much Electricity Can Your Solar Panels Generate?
This depends on a few variables such as amount of overcast(clouds), facing of your solar panels, and if there are any blockages between your solar panels and the sun (eg. trees, other buildings, etc.) Obviously, a solar panel is only able to generate electricity when it captures sunlight.
Solar Panels Companies have done some tests and suggests that a :
- 2.12KW solar panel system can generate about 8.8kWh per day.
- 3.18KW solar panel system can generate about 13.2kWh per day.
- 5.3KW solar panel system can generate about 22kWh per day.
An average 3 bedroom home consumes about 20-25kWh per day of electricity. This is a very rough estimate based on a single storey 3 bedroom home.
As you can see, a 5KW system size would seem ideal for most homes. Smaller system sizes are also acceptable if you are not looking to completely offset your power bill. Many home owners are happy to just cut their power bills by 50% or more.
So How Much Money Can You Really Save With Your Solar Panel System?
Again, anecdotal tests and research provides the following :
- 2.12KW solar panel system can save you $835 per year.
- 2.12KW solar panel system can save you $1250 per year.
- 2.12KW solar panel system can save you $2085 per year.
That’s averaging $175 per month savings on your power bill.
Going Off-Grid With Solar Panels
If you want to completely offset your power bill, and pay nothing to your power company, you will need to install a system size that can generate enough kWh per day to cover your full consumption. Since solar panels only generate power in the day, you will also need to install a solar battery, so as a to store up power to cover your night usage.
With a 10-14KW system size, it is possible to go off grid. Of course, that would require many solar panels (around 50!), which could be cost prohibitive for many home owners. However, if you are an corporate organisation, that would be highly possible.
