Overview of Technologies 
The most commonly used solar technologies include:

  • Monocrystalline
    Produced from a single silicon crystal and typically regarded as the most efficient crystalline technology.
  • Polycrystalline
    Produced from a piece of silicon consisting of many crystals. Less expensive than monocrystalline. 
  • Thin Film
    Considered less efficient than both crystalline types but also less expensive to manufacture. Because thin film is less rigid than the crystalline types, it is more resistant to physical damage. Thin film also weighs less and is more efficient in low light conditions.
  • Trackers
    Mechanisms on which photovoltaic panels are mounted. A small motor rotates the position of the panels to follow the sun's path from sunrise to sunset, thus increasing their efficiency. 
  • Inverters
    Convert the Direct Current (DC) produced by photovoltaic panels into Alternating Current (AC) that is used to power ordinary households.
