Many people look at the solar feed-in credit on their electricity bill or energy account and think that this is the the amount of power that their solar system has produced each quarter. This is incorrect.
Gross Solar Power is the actual power that your solar system generates. That is power before any use by household appliances. The Gross Power reading for each day can be found on your inverter. Refer to the below “How to read your Inverter”
Net Solar Power is the excess energy fed back to the grid after all appliances in the home have been powered (known as solar soaking) for daytime use. This is the reading found on the digital meter and your electricity bill or energy account statement.
It is important to remember that your solar system is set up to power your home first and foremost before exporting any unused excess energy to the grid. This means if your household’s day-time energy use has increased since the solar system was installed, you may see that your solar feed-in has dropped. This is not cause for concern and does not automatically mean that your system is malfunctioning.
