Solar energy is gets more popular with every leap in electrical rates and few people realize that it is the best investment in energy that you can make. The upfront costs can be large but a solar panel has no moving parts and its components are silicon, glass, aluminum and some copper for wiring.
The average panel is made up of 36 photovoltaic cells and the thickness of the cells depends on their power rating. Each cell is made up of two thin silicone sheets, one with a positive charge and the other with a negative one. Electricity is generated when the sun promotes electron activity between the two wafers resulting in a direct current.
The amount of electricity generated depends on the:
- Number of panels: Calculate your electrical needs for how many panels you will require.
- Type of silicone crystal: Like anything else there is quality and okay types.
- Sun and geographic location: Solar cells do not like shade and only trickle during cloudy days.
- Positioning: This has to do with where the panels are place and their positioning in relation to be maximum sun exposure.
- Care and Cleaning: Just like a window the glass on then panels needs to be cleaned foe better sun exposure.
- Regulation and Storage: Good news. Because of the interest in hybrid cars this technology is getting better and cheaper. Look for a spike in long-lasting batteries for solar energy storage at lower prices.
Buying photovoltaic solar panels is expensive so if you plan to run your home off this system you should perform a “triage” of sorts on your home. Remember, a toaster takes 1700 watts and that’s 17 solar panels or almost $20,000 for a slice of toast every morning. However, LCD-screen TV’s and computers take up a pittance of power.
