Does solar run during brownouts? It’s a common misconception and we receive this question on a daily basis. What is the answer? It depends.

Depends on what? It depends on the type of solar power system you have.

Grid tie system does not have batteries

Grid tie system does not have batteries

A grid tie system as the name implies is interconnected to your utility grid and its main purpose is to generate savings. The grid tie system ties your solar to the grid – that is its main purpose. It is not a power backup when the power is out. This kind of system does not have batteries. It does not have any storage for energy, which means that there is no possible way to save or store the harvested solar power. Now since this setup ties the grid to the solar, then it follows that when there is no grid, there is no solar. When it is brownout, the system shuts down. The grid tie inverter can detect if and when there is no power coming from the grid, and then shuts down automatically and immediately. There is no manual switching needed to be done, because the system is automatically synchronized. The inverter will automatically turn on and operate again normally once everything goes back to normal and the power comes back on. The Grid tie system is the most appropriate setup for areas with stable grid power.

Why can’t I just use batteries?

Why can’t I just use batteries?

The number one reason is because batteries are expensive. Battery-integrated setups will triple the total cost of the system, affecting your ROI or return of investment. In a grid tie solar setup, ROI is typically achieved in 4 to 5 years while in a solar setup with batteries, ROI can take up to 10 years or more. Keep in mind that lead acid can only last for an average of two years while lithium is only about 10 years, which means you need to constantly replace them after their lifespan is over.

Ultimately, the question is: do you NEED batteries? You will have to assess the location of the facility you plan to install solar on. If there is reliable grid power, then batteries are unnecessary.

We only recommend battery solar setups in power-starved areas or areas with unreliable and unstable grid. There is also another option of a hybrid system, which is a combination of grid tie and off grid system. On a hybrid system, your critical loads on your “emergency panel” will automatically run from solar and batteries, not only during power outages but all day every day.
