What does "Photovoltaic" mean
The term "Photovoltaic" is used to describe the process of converting sunlight into electricity. Photo stems from the Greek phos, signifying light. Volt is named after Alessandro Volta (1745-1827), a contributor in the study of electricity. Photovoltaic literally signifies light-electricity.
What is a solar cell?
By definition a solar cell, also known as a photovoltaic cell, converts solar energy into electrical energy. A solar cell is made of materials called semiconductors that are able to conduct, or carry electricity.
Note: Over 90% of solar cells produced worldwide are based on crystalline silicon semiconductor wafer technology. Next to oxygen, Silicon is the most abundant element in the earth's crust.
What is a solar module?
A solar module is a collection or series of solar cells wired together and encased in a protective cover.
What is a solar array?
A solar array is an interconnected assembly of solar modules with a support structure, which operate as a single power producing unit.
What are the components of a solar system?
Solar Modules: Solar modules convert sunlight into electricity.
Inverter: Inverters convert DC (direct current) electricity into AC (alternating current).
Charge Regulators: Charge regulators are linked between the solar modules, battery and load. Their main purpose is to protect the battery from overcharge or excessive discharge.
Batteries: Batteries store the energy generated by the solar modules.
Mounting Structures: Mounting structures are used to hold the solar modules securely in place.
How do solar systems operate in stormy weather?
Photovoltaics produce electricity by converting light into electrons, the less light available, the less electricity generated.
Do solar systemswork in cold weather?
Surprisingly, electricity generation is enhanced during cold weather conditions. Contrary to most peoples' intuition, Photovoltaics generate more power at lower temperatures, with all other factors being equal.
