How many volts does a PV module produce?

Cell: The basic photovoltaic device that is the building block for PV modules. All modules contain cells. Some cells are round or square, while thin film PV modules may have long narrow cells. Cells are too small to do much work. They only produce about 1/2 volt, and we usually need to charge 12 volt batteries or run motors.

Does proficad support photovoltaic circuit diagrams?

ProfiCAD supports the drawing of photovoltaic circuit diagrams. In addition to the common electrical engineering symbols, the library includes symbols such as solar cells, photovoltaic panels, solar collectors, inverters, etc. Should you need more symbols, you can create them in the symbol editor. Some sample drawings (click for full size):

What is a PV panel?

Panel: A group of modules that is the basic building block of a PV array. Panel is a term used for a group of modules that can be packaged and pre-wired off-site. The size of the panel (or large modules) is often related to how much weight and size two workers can effectively handle on a roof surface, such as you see here.

When can new PV modules be added?

New PV modules can be added at any time. Photovoltaic (photo = light; voltaic = produces voltage) or PV systems convert light directly into electricity using semi-conductor technology. (@ 10% efficiency) Thermal systems (hot water, pool heaters) produce heat from the sun’s radiation (@ +40 % efficiency) Large difference in value of energy types.

How do you ground mount a PV system?

Two common methods of ground mounting PV systems are racks and poles. Some pole mounts may also have the ability to track the sun across the sky. Another method of ground-mounting is a patio cover. This provides shade to the patio area without taking up valuable yard space. It also provides an alternative to roof mounting.

What is a PV module?

Module: A group of PV cells connected in series and/or parallel and encapsulated in an environmentally protective laminate. The PV module is the smallest package that produces useful power. The process involved in manufacturing these modules requires high precision and quality control in order to produce a reliable product.
