Types of Solar Systems Photovoltaic System
(PV)
Commercial
Utility
Concentrated Solar Power (CSP)
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
- 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

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
