Solar Electricity

Q: How does solar electricity work?
A: This technology is called “photovoltaic” or PV. Sunlight hitting silicon cells in a module generates a DC current. This current goes to an inverter in the house, which turns it into household AC. Grid-connected systems are linked to the regular electrical grid, and reduce the amount of current the house draws from the power company. Off-grid PV systems are completely independent of the power company. They require extensive battery backup and are more complex to install and run. Schüco specializes in grid connected systems, since these are easier to use for most people.

Q: Will a solar PV system give me electricity if there’s a power outage?
A: That depends on the kind of system you have. PV systems with battery back-up will provide electricity if the power goes out. However, the most common system design and the least expensive to install are grid-tied systems where no batteries are used. In this case, there will be no electricity provided during a power outage.

Q: Can a PV system give a dangerous shock?
A: A properly installed solar panel cannot give you a shock, and our mounting system keeps wires safely bundled and out of the way. An improperly installed or damaged module can give a shock. However, we work to the same electrical code as any qualified electrician, so there is minimal risk.
