http://www.askmisterwizard.com/Electricity/SolarPowerSystem/SolarPowerSystemPage01Full.htm Solar Power System at AskMisterWizard.com, Part 1. Building a solar power system for use at home requires understanding of 5 component parts: Solar Panels, Charge Controller, Storage Battery, Inverter, and wiring. This video clip shows how I mounted and wired all of those components in a system that generates 400 watts of continuous power in direct sunshine, and can deliver 2000 watts for periods of about an hour when demand is heavy.

Kids took shots at my array one evening and broke one of my panels.
No I didnt know about till 2days later and No I cant pin the kids for sure.
Anyways. Seems the tempered glass is glued to the solar cells.
Tried to remove the glass and want to use the panel as it for portable temp use but not sure how I can remove the glass without cell damage.
Yes its still putting out full power.
