How Do I Calculate What Size Solar System I Need

Introduction: Determining the right size for a solar system is a crucial step in transitioning to solar energy. Our Solar System Size Calculator simplifies this process by providing an estimate based on your monthly energy consumption. In this article, we’ll guide you through using the calculator and understanding the factors that influence the size of the solar system you need.

Formula: The size of the solar system is calculated by dividing your monthly energy consumption by a constant value. This formula ensures that the solar system can generate sufficient energy to meet your needs. Our calculator streamlines this process, allowing you to input your monthly consumption and receive a recommended solar system size.

How to Use:

  1. Determine your monthly energy consumption in kilowatt-hours.
  2. Enter the measured monthly consumption in the provided input field.
  3. Click the “Calculate” button to obtain the recommended Solar System Size in kilowatts.

Example: For example, if your monthly energy consumption is 500 kilowatt-hours, input this value into the calculator and click “Calculate” to receive the recommended solar system size, such as 3333.33 kilowatts.
