SUMMARY OF THE ELEMENTS OF A PHOTOVOLTAIC SYSTEM

Click on the underlined components to view a more detailed description.

 

Sunlight
 
Sunlight is energy in the form of light. It is the fuel of a solar (photovoltaic) system.
 

Solar Module
( Photovoltaics)

Solar modules generate DC electricity directly from sunlight. Use one or more modules depending on your power needs and the amount of sunlight available.
Mounting Structure
 
Mounting structures hold the solar modules securely in place. Ground, roof and pole mounts are available.
 
Charge Regulator
 
Charge regulators are the link between the modules, battery and load. They protect the battery from overcharge or excessive discharge.
 
Battery
 
Batteries store the energy generated by the solar modules.

 
Inverter
 
Inverters convert DC (direct current) electricity directly into AC (alternating current) to run many common appliances and equipment.
 
Load
 
The appliances, lights and equipment being powered are called electrical "loads". Energy-efficient loads contribute to overall system efficiency and economy.
Wiring / Interconnects
 
Proper wiring and connections for every segment of the system must be specified to assure best performance.
 
Back-up Supply
 
Compatible generator (i.e. Diesel) may be used as back-up for excessive power demands or during unanticipated long sunless periods.
 
Space
 
Solar modules should be installed in an area that is generally free from shade and receives as much direct sun exposure as possible.
 
Maintenance
 
Solar systems are one of the easiest and most reliable ways to generate electricity. Regular maintenance to check wiring, connections, batteries and overall system condition will help assure long-term trouble-free operation
