20kW Solar PV System: FAQ’s

1. How Much Cost Can a 20kW Solar Module system Save For My Business in Perth, WA?

The amount of money that you can save from a 20kW solar power system depends upon the electricity it can produce for your business and your electricity requirements. For example, if your electricity requirement is more than what the solar module system is producing, then the savings will be less. In this scenario, it is suggested to go with a bigger size of a solar module system. As per the experts, operating at 85% utilization, a 20kW solar PV system can help you save over $8,600 annually. And if you are using less energy, the figures can go higher.

A 20kW commercial solar panel in Australia reduces the electricity bill for commercial hubs by feeding solar power directly into the main phase of power supply, resulting in saving energy. So, if you are saving over $8,000 annually and the purchasing cost of the 20kW commercial solar panel is $25,000, then it will be totally free for you in almost 3 or 4 years.

The huge savings on electricity bills for businesses make it an attractive investment choice, especially when you are living in Perth where the electricity charges are higher than other states of Australia.

2. Can 20kW Solar Array Go Off-Grid?

Well, that depends on many factors. Although almost all of the 20kW solar systems are designed to go off-grid, there are many factors that play an important role in this process. For example, if you run a business with a 20kW solar system on the top. If the solar system is producing enough electricity than your daily consumption, then the power can be transferred to the batteries attached to the solar power system. 

Whether or a not you can tie with the grid with a system of this size depends on a number of things, including:

  • Location: If you are living in a place where the weather is shiny than the other places than you can produce more energy throughout the day time. So, place the solar units as high as you can.
  • Roof Orientation and Tilt: When planning to install the 20kW solar systems in Perth, make sure that the panels don’t face east and west as these arrays tend to produce a bit less, and south-facing arrays least of all.
  • Electricity Requirements: If you consume more energy every day than what the 20kW commercial power system is producing, it will be hard for you to install a solar storage system that can make you self-sufficient.
  • Energy Requirements: Remember that if you want to go off-grid, it is important to save enough energy to get you through 3-4 days of rainy weather. Your solar panel should be large enough to charge your battery bank. 

3. Is 20 kW Solar Energy System Suitable For My Business’s Needs?

Once you decide to finally install a photovoltaic system for your commercial unit’s energy requirements, the first thing that comes to your mind is “Is 20 KW Solar Energy System Suitable for My Business’s Needs?” Whether it is enough or not, depends on various factors. Although it is always suggested to choose a system with higher electricity generation capacity, it is important to understand the following factors before you choose 20kW commercial solar power system installation.
