Technical FAQs 4

Does Unused solar power go to waste?

Solar panels are versatile pieces of tech that don’t require external assistance to work. That is the reason why there can be times when your panels could generate more electricity than you need to run your everyday chores. So, what happens to unused solar power? Does it go to waste? Not quite.

Do solar panels produce more energy than is consumed?

Solar panels always produce energy when the sun is out. The energy is used to whatever load is connected to the system, but what happens if your panels produce more energy than is consumed? In a grid tied system, excess solar energy is sent to the grid where you can tap into it anytime.

What happens if a solar panel is disconnected?

With the load disconnected you have voltage (i.e. potential) but no current. Since the charge carriers liberated by the incoming light energy have nowhere to go, an equilibrium is developed in the panel. So where does the energy go? It becomes heat energy in the panel which is ultimately radiated or conducted away.

Can solar panels be turned off?

Let us explore more on the topic. If you have a solar system that is connected to the grid, you can expect the excessive energy to be transported back to the grid. Solar panels are made in a way that it’s not possible to physically turn them off.
