How to work out what size solar solution I need for my business or home.

To determine the size of the solar installation you need to cover your current energy usage and future increases due to inflation, you need to consider several factors.

Here’s a step-by-step guide to help you calculate the right solar system size for your home or business:

Step 1: Assess Your Current Energy Usage

The first step is to determine how much energy you currently consume. You can do this by reviewing your monthly electricity bills, which typically show:

• Kilowatt-hours (kWh) used per month or year.
• The cost of electricity per kWh.

You can also use a smart meter or energy monitor to track your usage more precisely if needed.

Example:

• If your monthly electricity bill shows that you use 800 kWh per month, this is your baseline energy usage.

Step 2: Calculate the Solar Energy You Need

To cover your energy needs, you’ll need to estimate how much solar energy you need to produce. A typical residential solar system is designed to meet 80-100% of your energy consumption.
