For many, investing in solar power is a major financial decision and not one that should be taken lightly. There are several benefits to solar power and it pays to have a good knowledge of these. Our site is designed to help you make the right decision. In fact you may wish to simply use our solar power calculator and our free quote service to recommend an installer and be done with it. More likely, you’ll want an understanding on each of these topics below to add weight to your decision.
It depends, but most likely yes. Unless you are considering going off the grid and buying a stand-alone solar power system, you’ll still pay electricity, even if your system generates enough power to satisfy your household energy needs. If you are connected to the electricity grid, your retailer will charge you a daily fee to access it, a supply charge.
It’s true. Your solar panels only generate electricity during the day. If you are connected to the grid, you’ll have to buy electricity from your retailer when you need to use it at night.
It’s possible to add a solar battery to your system and have it store the excess energy that your system generates during the day. This way you can use it at night without having to buy electricity from your retailer. The costs of solar battery systems are coming down considerably; innovations like Tesla’s Australian Powerwall battery are making battery storage a more viable option.
If you don’t decide to go ahead with a solar storage solution, your retailer will buy back the excess solar power that you generate during the day, but don’t use. This is called a feed in tariff. Unfortunately, for most Australians, the buy back rate is particularly low, it’s far better to use the solar power that you generate.
Determining what size system you need depends on a number of things: how much electricity you use, your location, the system cost, how much electricity you use during the day, are you adding storage and how much electricity you wish to power with solar energy. We cover this topic in great detail and help calculate your optimal system size.
Solar system costs vary depending on the size of your system and the ease of installation. You can run the sums on solar panels of different sizes to see how much they cost using our panel cost calculator.
When an installer quotes you a price, it’s likely that this price will include the solar rebate that you are entitled to receive. The value of your solar credit varies depending on the size of your system and where you live. You can find out more and calculate your solar rebate here.
Investing in solar power can be expensive. It may be worth your while considering financing your purchase and avoiding the upfront cost. There are a few alternatives; you could choose to add the cost of your system to your existing mortgage, you could take out a specially tailored solar loan, or you may choose to lease your solar system.
