How is solar power consumed before grid power
While I was informed I would be using the solar power first, and any remaining needs would come from the grid, as well as sending any excess to the grid, I didn''t really understand it. Now that I''m using the system, I can clearly see (by watching the meter) that I truly do use the solar power first.
safety
Solar power inverters that send excess solar power back to the grid are (usually) required to shut down if the grid power fails. (This is to protect people working on the power lines.) The inverter only has two wires connecting it to the switchboard. (Active and Neutral).

6 FAQs about [Why doesn t the power grid use solar power ]
Can a solar energy grid be dominated by wind and solar?
But you can’t have an electricity grid dominated by wind and solar without supplementing it with massive amounts of storage. The cheapest way of storing energy according to the US Department of Energy, by the way, is by using surplus power to fill an underground chamber with compressed air, then releasing it to drive turbines.
Are solar panels grid-tied?
Your panels aren’t grid-tied. If you live in some kind of cabin or farmhouse that isn’t connected to the national grid, then your home will carry on drawing power as normal, whether that’s from solar, wind, a diesel generator or something else. Or, you have a solar battery with backup power functionality.
Why do we need to connect renewables to the electricity grid?
In order for homes and businesses to use cleaner, greener energy, more renewables – such as solar power and wind power – will need to be connected to the electricity grid.
Will a grid-tied solar system still have power during a power outage?
One of the biggest misconceptions we hear most often is that a home with a grid-tied solar system (without battery backup) will continue having power during a utility power outage. This stems from a misunderstanding of how grid-tied installations work.
Can a solar system back feed to the grid?
Although a solar system with batteries can also back-feed to the grid, it can operate independently during an outage only because this system functions as a micro-grid: the batteries give power to appliances, and the array provides only enough power to refill the batteries to 100%.
