Correctly sizing a solar panel system for your home

When it comes to solar panels it’s important to correctly size your solar panel system and to do that you need to work out how much electricity is being used at your home and when you using it.

Let’s look at a typical Australian home which might use around 20kWh per day, this type of home would require a 5kW solar panel system.

A really important factor to mention is the actual number of panels is not as important when choosing a solar panels system; it’s the system’s overall capacity that should be considered.

The great news is as the technology improves over the years and demand for solar panels continues to grow, solar panels have become fairly cheap so it makes sense to get the biggest system possible.

       The actual number of panels is not as important when choosing a solar panels system; it’s the system’s overall capacity that should be considered.

If you’re thinking of going solar with your home, knowing what size of solar panel system you’ll need to run your home on solar power as often as possible is essential.

Remember the size or capacity of a solar PV (photovoltaic) system dictates the maximum electricity output the system can deliver.

We can’t stress this enough, a good solar system has little to do with the number of solar panels provided, and everything to do with the overall capacity of the system.

Example: You might see an offer for a solar system that might include 20 x 250W panels, and another might be offering a system with 25 x 200W panels; in either case the output capacities could be exactly the same for both (5000W or 5kW) systems. The output number is the only number truly matters.
