The earliest applications of PV Systems were in situations where connections to the utility grid were unavailable, or cost prohibited. As PV efficiency has continued to improve and costs have fallen in recent years, more potential applications for PV technology have emerged. Greater demand and increasing production have accelerated the trend toward cost-effectiveness in a wide range of applications.
Today, PV Systems can be used in almost any application where electricity is needed and can support DC loads, or both.
PV Systems may be as simple as a PV module directly connected to a load with no other components, or as complex as a utility-interconnected system with multiple power sources.
Satellites were the first practical applications of PV technology and did much to increase the public´s knowledge of PV Systems.
Portable PV Systems power mobile loads such as vehicles, temporary sign and lightning and handheld devices.
Remote PV Systems power loads that are permanently fixed but too distant to be connected to the utility power grid. Off-grid residences, lighting, communications, signage and signals, remote monitoring, water pumping.
Systems that are connected to the utility grid and use PV energy as a supplemental source of power offer the greatest flexibility in possible system configuration.
PV Systems can be used to provide supplemental power to any utility-connected building or structure, including residences, commercial, building, factories, and institutions. These applications are all similar, except that the system varies in size. Array mounting systems may also vary because of the difference in construction methods and design.
So, what are you waiting for to be part of this great transition? If you are thinking that PV Systems are the future, then you are already late.
