Why You Should Install Solar Panels For Your Home
There are many benefits to installing a solar power system for your home. Especially if you live in Adelaide. South Australia gets more sunlight than other states which means your solar panels can generate more energy for your home. Below are some key benefits of solar panels.
The Benefits of Solar Panels
- Clean Energy – Free Electricity Generated Directly By The Sun
- Cuts Your Energy Costs Down Significantly
- Saves The Environment – No Greenhouse Gas Emissions
- Increases The Value Of Your Home
- Long Warranties (Lifetime Guarantees For Some Parts)
The best benefit is that you will feel good using clean energy.
How Do Solar Panels Work
Solar Panels capture sunlight and converts the sun’s energy into electricity. A solar inverter than converts that electricity so it can be used by appliances in your household. Any excess electricity that is unused will then be put back into the power grid which will possibly earn your a feedback tariff from your power provider. You can also install solar batteries to store electricity for use at nights or when you require more power. If you put in a solar battery, the solar panel system will first charge the battery, and then deploy excess electricity to your home. Any further excess will then be returned to the grid.
How Much Power Can Solar Panels Generate
Solar Panels come in various system sizes. This starts from 1.5KW and goes up by 1kW increments. So you could choose to install a 2kW, 3kW, 4kW, 5kW or more system. Each panel roughly has a capacity of 250w. So a 1.5kW system will require 6 panels, a 2kW will require 8 panels, while a 5kW system size will require 20 panels. See below for a chart of how much power each system size can generate : * System specifications are estimates and may change without notice.

Typical Solar Panels Array
Solar Panels are best placed on the north facing roof of a house. A 20 panel array could usually fit into the north facing roof of a typical house.
If you have a house with it’s width facing the north, you may not be able to fit all the panels on the north facing roof. In that case, you may need to make use of the West facing roof as well.
Generally, solar panels are not recommended on the east or west facing roof, as the sunlight exposure is not optimal.
Solar Panels System Size – By Usage Pattern
Before you can decide on which solar panels system size you require, you will need to determine your home energy usage pattern. Some families use more electricity during the day (ie. if more people are home during the day). Other households may use very little during the day and a lot more during the night. Depending on your consumption pattern, the sufficiency and ROI for your solar panels will vary. Let’s look at a few usage scenarios below. Important : Below examples assumes a total daily energy usage of 26.86kWh. Household 1 : Average Energy Consumption 50% Day Usage / 50% Night Usage. Daytime consumption : 13kWh Suitable System Size : 3.24kW Household 2 : Heavy Day Consumption 70% Day Usage / 30% Night Usage. Daytime consumption : 18kWh Suitable System Size : 5.4kW Household 3 : Heavy Night Consumption 30% Day Usage / 70% Night Usage. Daytime consumption : 8kWh Suitable System Size : 2.16kW
