Photovoltaic Systems and Applications


Principal Elements of a Photovoltaic (PV) System

use

inversion (AC) & conditioning

energy

source

distribution

conversion (DC)

electric

utility

storage


Types of PV Systems

  • Utility-interactive (or grid-connected, or grid-tied) PV systems

  • Stand-alone PV systems


Inverter

PV Array

Service

Panel

Distribution

System

Loads in Home

A Simple Grid-Tied Photovoltaic System


Solar Electric, Thermal and Energy Efficiency

  • An effective and highly marketable combination

  • Both electric and thermal power produced on site

  • A giant step toward the zero energy home


Side-by-Side Tests

Finding the efficiency limits

Standard vs. Best Available


The Potential of PV and Building Technologies


Net Energy Use


Integrating PV Systems and Buildings

PV System Strengths and Weaknesses


Myth that Solar Energy Uses too Much Space

Lake Mead formed by Hoover Dam has an area of 640 km2. The dam has a capacity of 2,080 MW. If the same area was covered with 15% efficient solar modules, the peak solar output at noon could be at least 60,000 MW!

This includes a large margin for DC-AC inverter loss and the spacing between PV array rows
