College entrance exam questions on solar power stations

Why should you take a solar PV course?

This course aims to boost confidence and assist those who are intending to prepare for industry exams like NABCEP Associate, along with learning of the foundational principles of solar PV systems and essential theories including calculations.

What is a solar power system?

An electrical system consisting of a PV module array and other electrical components needed to convert solar energy into electricity usable by loads. Fig 1-2. Most electricity is distributed through an electrical utility grid to millions of customers from a relatively small number of large power plants.

What is a concentrating solar energy collector?

Concentrating collectors have increased efficiency and reduced size because of the ability to channel more solar radiation onto the desired surface. A solar energy collector that enhances solar energy by focusing it on a smaller area through reflective surfaces or lenses. Fig 1-23.

How much current does a solar panel use?

Range of current causing muscle contraction, typically 10-20mA. Authorization needed from the utility to connect solar energy to the grid. Measured in Volt-amps (VA) or kilovolt-amps (kVA). Factor considered by installers to increase light on pv in low sun conditions. Range of current causing muscle contraction, typically 10-20mA.
