It’s important for you to understand what you are getting and to know what your system will do for you.
If you have any other questions that are not listed here, please get in touch, we’ll do our best to answer them for you.
The amount of money saved is determined primarily by the amount of panels installed, however other factors such as the position of the panels and various installation conditions will also play a contributing factor. As a general guide, using a price of 25 cents per kW, you could expect to save approximately $400 per kW of power. So for a 6kW system, you could save up $2400 in one year. (6kW x $400 = $2400). This is assuming you are using the power produced and not selling it back to the grid.
In order to work out what size system you need we first need to determine how much energy you are currently using. This information can be found on your electricity bill. Your bill will show your daily average electricity usage in kWh (kilowatt-hours), some bills will use the word ‘units’ instead. If there is no daily usage amount shown, take the monthly average and divide by 30 or the yearly average and divide by 365, either will give you your daily average. In Sydney 1kW of solar will generate approx. 4.5kWh of energy per day. If your daily energy usage is 20kWh then you just divide 20 (your daily average) by 4.5 (kWh produced daily) and this will give you the size of the system you need to meet your needs, in this case it equates to a 4.4kW solar system.
Every solar battery works slightly different depending on the particular product and how it’s integrated into your solar system.
In general, however, a solar battery will store excess electricity which has been generated by your solar panels for later use.
Firstly, your solar panels convert sunlight into DC electricity. Consequently, your inverter or microinverters will convert this DC electricity into AC electricity, which is what most home appliances use. Any excess electricity that your home doesn’t use immediately will be stored in your solar battery. The electricity has to be converted back to DC to be stored in the battery.
When your solar panels aren’t generating enough electricity to meet your home’s needs (like at night or on a very cloudy day), your battery can discharge the stored electricity. Again, an inverter is used to convert the DC electricity from the battery to AC for use in your home. The benefit of having a solar battery is that it allows your home to use solar electricity even when your panels aren’t generating it in real-time. It can also provide a source of backup power during a grid outage, if your system is designed to do so.
There are several types of batteries commonly used in solar energy storage systems. Each type has its own characteristics, advantages, and limitations.
Enphase batteries are designed using lithium iron phosphate technology, which deliver unrivaled durability and performance compared to most other storage technologies and pose fewer environmental, health, and fire risks.
Tesla Powerwall is a lithium-ion battery designed for residential energy storage. It utilises lithium-ion battery chemistry, specifically lithium nickel manganese cobalt oxide, which is commonly used in rechargeable batteries due to its high energy density, efficiency, and long cycle life.
Every installation is different and we will advise you what the lead time is for your specific installation from signing your contract to flipping the switch. A typical residential (solar system only) installation will take anywhere from 1-3 days depending on your system size and the weather.
If you generate more energy than you use you can sell it back to the grid OR you may like to consider a battery storage system, this option is becoming more and more popular. Rather than sell your excess energy back to the grid it can be stored in a solar battery. Solar batteries work by storing the energy that is produced by your solar panels and storing it for later use. Excess energy will only go back to the grid if your battery is full.
One thing to remember is solar energy of course comes from the sun. So if it’s overcast less energy will be produced. When the sun sets, no energy will be produced. In these situations you may need to buy energy from the grid to meet your needs, however if you have a solar battery storage system in place any excess energy your system produces will be stored and ready for use when it’s needed.
