A solar system can reduce your carbon footprint and is an excellent step towards more sustainable living. Solar panels currently produce 6.5% of Australia’s total energy generation. The more solar panels installed, the higher this figure will become.
Are you ready to make a difference and install solar panels for your home?
This guide will show you exactly how to calculate what solar system size is right for your home, including how many panels you need. Read on to take the first step in your journey towards living greener and cleaner to sustain the planet.
Calculating Your Budget
Before calculating what solar power system size is right for your home, you should figure out how much you are willing to spend.
Suppose your budget can’t cover the costs of using solar panels to provide all the energy for your home. In that case, go for an interest-free payment plan. It’s more affordable, and you will pay less than the savings offered from the solar panels.
The panels aren’t the only factor in your budget, as you will also need a solar inverter and possibly a solar battery.
When calculating your budget, it is crucial to remember that the panels will save you money in the future on your energy bills and will add value to your home if you plan to sell later on.
Working Out Your Home’s Energy Usage
To know exactly how much energy your solar panels need to provide for your home, you need to work out your home’s current daily energy usage.
To calculate your household’s daily energy usage, you will need to look at your electricity bills. If the figure is not displayed as a daily amount, some calculations are required. If the energy usage is displayed as a monthly amount, you should divide this figure by 30 to gain an average for your daily energy usage.
Working Out Your Daily Target For Energy
Some days you may use more energy than others, so your solar panels must provide enough power to account for the days when you use more energy. In addition to this, your solar panels may be exposed to more sunlight depending on the day and the season.
For this reason, you should ensure that your daily energy target is around 25% higher than your daily energy usage. This means that you shouldn’t run out of power if you use more energy than usual or if there isn’t as much sun exposure on that day.
How Many Panels Will You Need?
The quality of your solar panels is an essential factor in determining how many solar panels you will need for your home. The amount of sunlight you receive is also an important factor. To calculate the number of panels you will need, you first need to divide the hourly energy usage of your home by your daily energy usage in kWh. Then, times this figure by 1000 to estimate the watt usage.
To get an estimate for how many panels you will need, divide the hourly energy usage of your home by the wattage of your solar panels. The wattage of your solar panels depends on the quality and type of solar panels you choose.
Once you have these estimates, you can get in touch with your installer, who will verify your calculations and determine how many panels can be placed on your roof. The installer will calculate the angles that your panels should be placed at for optimal energy output and ensure your calculations are correct.
Once you have made your calculations, you should call up your local Sydney solar panel installer and start planning your solar panel installation. Installing solar panels provides an excellent return on your investment, adding value to your home and saving you money on electricity bills. In addition to these benefits, you will also be taking better care of this planet we call home. Get in touch with the friendly SolarPath team today for more information.
