HOW MANY SOLAR PANELS DO YOU NEED?

The question most purchasers ask when getting a solar system installed is “how many solar panels do I need to get?” Depending on how much electricity you need, the number of solar panels you need varies.

What should you ask yourself before you get have your solar panels installed?

  1. How much optimal roof space do you have?
  2. What system size have you been approved to install by your energy retailer?
  3. Does the size of your desired system comply with the state government feed-in tariff criteria?
  4. How much is your budget
  5. Do you want to reduce your energy costs, get rid of your bills completely or receive a cheque in the mail yearly?

What do you need to take note?

Solar panel sizes vary. There are solar panels that produce 170 watts while there are others that produce 250 watts. It is important to watch out for the system wattage rather than the number of panels. The size of the system also depends on the total wattage produced. A bigger inverter works well if you have plans of upgrading your power system in the future.

There are on-site assessment services offered by some companies and businesses to determine how many solar panels will be needed. The on-site assessment will help you know how many solar panels will be needed for you to be able to generate your target wattage.
