Build Solar Panels For Free

A photovoltaic module is made up of solar cells which use a photo-electric effect to generate electrical energy. Electromagnetic radiation reaches the front of the plexiglass in a solar panel and converts sunlight into a DC current. Since this renewable energy source is free, a photovoltaic module is commonly used by residential and commercial companies. Although most solar panels are expensive but you can also build solar panel free of service charges and excessive materials costs.

To build solar panel free of financial hassles, you must gather all the necessary equipments first. The things that you need to create your free solar panels are copper sheeting, an electric stove or a hot plate, sheet-metal shears, sandpapers, micro-ammeter that can read currents lower the 50 microamperes, two alligator leads, a plastic bottle, water, and two tablespoon full of salt. You must first cut two rectangular copper sheeting with the size of an electric burner. Clean it with sandpaper and lay it down on top of the burner. The maximum heat applied will change the color of the copper into black.

Leave it for 40 minutes until you see the heavy coat of oxidized black material. Turn off the burner and cool the copper on air for 30 minutes. Scrub the copper sheeting under running water but be careful not to remove all the oxidized material. Cut off the top of the plastic bottle which will become the makeshift bucket. The copper sheeting should be bended slightly to fit in the contours of the bottle but should not be touching each other. An alligator clip is placed on second (uncooked) sheet unto the positive terminal of the micro-ammeter while the next alligator clip to the first (cooked) sheets which lead to the negative terminal. Stir salt into several cups of hot water and pour unto the bottle leaving the alligator clips dry. Place it under sunlight and observe the needle of the ammeter as the apparatus begins to charge.
