A breaker is like a light switch at the electric panel that shuts off certain sections of your homes' power.
The type of current the sun provides.
This is box where the power from the utility company is brought into your home. It is the hub for redirecting the electricity. Also, it ties into your circuit breaker and utility meter.
Short for "end clamps." They hold the solar panels onto the rails so the wind can't lift them off.
An inverter changes the direct current into AC current which runs your home appliances.
The mids are like end clamps except that they're placed in between two panels so they support the panels in the middle.
Oversizing means providing the customer with more energy than their present needs require. This is often a good idea if say, the house owner knows they’ll be getting an electric car or installing a swimming pool which would require more power than they currently use.
A 14 foot long rail where all hardware is attached so that nothing touches the roof. This includes the quick mounts, the solar panels, the micro inverters and all the electrical wires.
The solar panel collects the direct current from the sun and feeds it to the inverter.
Undersizing means a solar company estimates that you need fewer solar panels and less electricity than you actually do. By undersizing, they can lower their bid and your cost estimate.
However, it's like saying your new car will get more miles per gallon than it actually gets. While undersizing will save you money upfront, you're likely to still get a utility bill because you won't be generating all the electricity you need.
