Understanding the solar self-consumption rate

You've probably heard of photovoltaic self-consumption rates. It's essential, because it's by controlling it that you'll save money. In this article, ME Green explains what the self-consumption rate is, how to calculate it and how to optimize it.

Self-consumption rate: what is it?

  • The self-consumption rate is the ratio between the electricity you produce with your solar panels and the electricity you consume, and your total electricity production. There are three ways of using your solar power production: total self-consumption, partial self-consumption and selling all your solar power production.

How to calculate your self-consumption rate?

  • The formula for calculating your self-consumption rate is quite simple: it's your solar electricity consumption divided by the electricity generated by your photovoltaic system, then multiplied by one hundred.

How to optimize your self-consumption rate?

  • To improve your self-consumption rate, several factors come into play. First and foremost, the size of your installation is crucial. A well-sized installation will enable you to easily achieve a higher self-consumption rate. Shifting your consumption to times when the sun is shining can also help. Finally, the ultimate solution for achieving a high self-consumption rate is, of course, the solar battery, which enables you to store the surplus electricity produced during the day for reuse when you need it.


Now that you have all the information you need on self-consumption rates, it will be easier for you to make your photovoltaic system profitable as quickly as possible. At ME Green, we're here to support you in this process. Please contact us at info@me-green.net for more information.
