This average system size compares to neighbouring suburb Calivil which has an average system size of 11.0kW. These solar systems help Tennyson residents generate enough electricity to significantly reduce their reliance on the electricity grid.
Solar Power Pricing in Tennyson
According to our recent research, the price range for a 6.6kW solar system supplied and installed in Tennyson after government rebates can range between $3,000 to $5,000.
This price can vary a lot as it depends on factors such as your roof type, solar panel quality, inverter quality and so on. For example, microinverters can add several thousands of dollars to the cost of a 6.6kW solar system.
Solar Panel Performance in Tennyson
For an unshaded, north facing well performing 6.6kW solar system located in Tennyson, we estimate that you may generate on average around 25kWh/day.
How much money will solar panels save me?
We just estimated that a well performing 6.6kW solar system installed in Tennyson may generate 25kWh/day on average throughout the year.
To estimate how much this can save you on your electricity bill, we need to make a few assumptions. Let’s assume the following items:
- Electricity cost is 25c/kWh
- Solar feed-in tariff is 5c/kWh
- Percentage of solar generation dicrectly consumed is 50%
- Percentage of solar sold to the grid is 50%
Give the above assumptions, we estimate that the annual savings could be $1,364 per year.
This represents a simple payback time of 2.9 years which some may say is a pretty good return on investment.
Solar Finance and Green Loans in Tennyson VIC
These days, may households decide not to pay cash up front for their solar system, but to use a green loan or solar finance.
This is growing in popularity as for zero dollars up front, sometimes the amount saved on your powerbill by installing solar panels more than covers the solar finance repayments.
To estimate the solar finance repayments in Tennyson, let’s first make some assumptions:
- Solar system size is 6.6kW
- Cost of solar system after rebates is $4,000
- Interest rate is 8% per annum calculated monthly
- Term of green loan is 5 years
- Annual solar savings on powerbill is $1,364 (this was taken from above)
- Establishment feed or admin fees have not been included
The cost of solar finance using the above assumptions is $973 per year.
This means that you may be able to install solar panels on your home for zero dollars down and it is still cash flow positive. “Cash flow positive” means that the savings you get from your solar system on your power bill exceed the annual repayments for your green solar loan in the first year. In other words, you’re saving more money on energy costs than you are spending on the loan, resulting in a net gain in cash flow.
The above example is an estimate only and of course you need to check these numbers independently with a profiessional financial advisor rather than relying on our calculations.
Government Rebates for Solar in Tennyson
Tennyson residents can take advantage of several solar rebates to reduce the upfront cost of solar panel installations. The Federal Government’s Small-scale Renewable Energy Scheme (SRES) provides rebates for solar panel systems. Homeowners can receive certificates that can be traded for cash at the point of installation, significantly lowering the cost of installation.
Under the solar rebate scheme, Tennyson is situated in Zone 3; consequently, this classification affects the available benefits for solar installations. Therefore, a 10kW solar system in Zone 3 can generate 96 Renewable Energy Certificates. Assuming, moreover, that the amount paid per certificate is $37, we can calculate that the total rebate applied as a point-of-sale discount amounts to $3,552.
The price paid for each certificate does fluctuate so keep that in mind. On top of this, there are conditions for the eligibility of a government rebate so it is best to talk to a solar professional how it pertains to your situation.
Solar Panel Tilt Angle for Tennyson
Often times people ask what is the best angle to mount solar panels so that they generate the most energy throughout the year. This is almost always determined by the roof you happen to have on your house.
According to the Solar Radiation Data Handbook, a very good placement for solar panels located in Tennyson is 36° from the horizontal; therefore, this angle maximizes solar exposure and enhances energy efficiency.
It is very unusual to find a roof with the perfect pitch facing north in Tennyson, however, do not despair, it is often still worthwhile to install solar panels, nevertheless, as the losses of solar panels mounted at 25° instead of 35° is fairly minimal.
Sometimes it can be a good idea to mount solar panels facing West. The reason for this is because West facing solar panels can generate more electricity in the afternoon as the sun is setting.
This can correlate with the price of electricity in some markets; consequently, prices may increase in the afternoon as the demand for electricity rises.
Again, it is best to talk to a solar professional to see what is the best valley for money. solar panel placement for your situation.
Battery Storage Adoption in Tennyson
Energy storage is also gaining traction. Home battery systems allow homeowners to store excess solar power generated during the day for use at night or during cloudy periods. This setup maximizes the benefits of solar energy by ensuring a consistent power supply and further reducing electricity costs.
