2. How Solar Panels Work

3. Specs  56.1x25.7x2.2 creates a max output of 130 watts  Usually lasts around 20 years  Start declining in out put after 10 years (usually loosing around 10%)  56.1x25.7x2.2 creates a max output of 130 watts  Usually lasts around 20 years  Start declining in out put after 10 years (usually loosing around 10%)

4. Ideal Uses  Recreational vehicles  Summer homes  Emergency communication systems  Recreational vehicles  Summer homes  Emergency communication systems

5. Construction  Virtually a maintenance free power supply  4 main items on a stand-alone system  solar module  charge controller  battery  inverter  Virtually a maintenance free power supply  4 main items on a stand-alone system  solar module  charge controller  battery  inverter

6. Mounting Structure

7. Direction  For best year round power output with the least amount of maintenance, the panel should set the solar array facing true south at a tilt angle equal to your latitude with respect to the horizontal position

8. A look Ahead  Solar panels currently are not efficient enough to produce the amount of energy needed for a common US household  Advances are being made annually to improve the quality of solar panels  Since 2002, solar panels have become 48% more efficient then the previous year  Solar panels currently are not efficient enough to produce the amount of energy needed for a common US household  Advances are being made annually to improve the quality of solar panels  Since 2002, solar panels have become 48% more efficient then the previous year
