Types of Solar Systems Photovoltaic System (PV) Commercial

Utility - Converts direct sunlight into electricity right in the panel - Used in residential, commercial and large scale power generation - Less expensive and less heat/conversion losses

Concentrated Solar Power (CSP) Utility - Sunlight is used to heat up salts in the main tower to 400 -500 degrees - Used in large scale power generation - Less expensive and More heat/conversion losses

Concentrated Solar Panel (CSP)

Photovoltaic System (PV)

Residential Solar Installation  Grid Connected Systems  Grid acts as a battery for excess energy generated  Best option for markets with 80% or higher Grid Efficiency  Pros: Inexpensive  Cons: Grid goes down, PV goes down  Off Grid Systems  Needs batteries to store energy  Pros: Supplies power at all times  Cons: Expensive, requires sizeable space for batteries
