Why Install Solar Panels On Your Home

Why Install Solar Panels On Your Home?

Here in Queensland we are heading towards a very hot summer. Hot summers equal more electricity use and increasing costs. So why install solar panels on your home? In this blog we will discuss the costs and the pay back time for your solar investment.

What Is A Solar Break Even Point?

This solar pay back time is also called the “solar break-even” when the electricity savings start to be greater than the actual price of your installed solar system. This break even point is also a great way to compare the return value of different solar panel systems for your home.
A good solar system installer will be able to estimate your break even time once you decide on the best  size for your property and energy usage needs. The exact amount you will save will depend on how much electricity you use, what time of day you use electricity, how big your solar system is, whether your house is shaded or is in full sun, what direction the roof faces, whether you get a battery installed, and whether you also install intelligence software to maximise your savings even more.

What Do STC’s Have To Do With The Best Time To Install Solar?

STC’s (Small scale technology certificates) are a government rebate that can cut payback time for your solar even further. These STC’s are allocated based on the size of the solar PV system you have installed as well as the location of your home.

With the value dropping every calendar year, the longer you wait to install your solar system the less rebate you will receive. Right now, in 2019, your eligible rooftop solar system would receive one STC for every estimated 1,000 kilowatt-hours of electricity it would generate until 2030.

With a reduction to the rebate coming into effect every January, the earlier you take up the rebate, the more money you could save. The scheme is planned to be in place until the end of 2030. 

How do Feed In Tariffs Factor into the cost?

In a nutshell, when solar panels produce electricity and no one uses it, this power is transferred to the shared energy grid. For every kWh of electricity that your solar panels export, your energy distributor will rebate a few cents off your electricity bill. The feed-in tariff rate has been reduced in recent years due to ongoing cuts in government subsidies.

The minimum flat-rate feed-in tariff in regional Queensland is 9.369c/kWh, while South-East Queenslanders (on the Energex network in the Brisbane area) receive a voluntary FiT that’s usually around 10c/kWh. Some energy retailers may offer even higher FiTs – AGL and Click Energy both have solar deals with FiTs of 20c/kWh and 16c/kWh respectively.

How To Save Money When You Install Solar Panels?

The cost and saving of your solar energy installation is influenced by both your household electricity use as well as the size of the solar power system you install. Most qualified solar installers take into account your solar panel configuration, the type of inverter as well as issues like shading and spikes in electricity use.

sonnenBatterie solar battery 273x300 - Why Install Solar Panels On Your Home?Unless you also install a battery, solar panels only provide electricity when the sun is shining. Therefore, using your appliances a lot during the day if you are at home, means you will get more out of your panels.

Likewise, without a solar storage battery (like the Tesla Powerwall 2 or the  sonnenBatterie), if you are at work all day you will still need to access the grid at night for your energy needs, costing you more money.

Some people run their washing machines or other appliances during the day to maximise their use of solar electricity, but to get the most out of the system, it’s a good idea to also run water heating, or space heating and cooling during the day.

The Alternative Technology Association found it was important to switch away from gas-powered hot water if households wanted to get the best value for money from solar. In a recent report the Association analysed the impact of the changes to feed-in tariffs in NSW, Victoria and South Australia.

“With space heating and hot water generally comprising somewhere between 50 per cent and 70 per cent of a home’s stationery energy needs, it is difficult to maximise the use of solar PV without using it to power one of both of these major loads,” the report said.

In Conclusion

Getting your solar system installed before 2020 will also mean you are benefiting from a higher STC rebate.
