When considering a commercial solar system for your Perth business, you may want to know a little bit about what to expect from the entire process. The first step in the process is choosing a suitable solar panel. Not only should you select panels that have the maximum solar output, but you should also decide how many panels you need. You can then decide which panels to install and how many solar inverters to purchase. In addition, you'll need to make sure that you have the necessary permits and utility interconnection agreements.
