Why Choose Solar Energy?
Here's Why
Pros and Cons
How Are Solar Panels Made and How Do They Work?
Discovery
During the day, solar panels store as much energy as possible. Each solar panel can store different amounts of energy though because they are all measured on the amount of kilowatts per hour the solar panel can store. The good thing is that solar panels conserve fossil fuels.
There are two types of solar panels, crystalline silicon and amorphous silicon. The crystalline silicon wafers are grown into cylinders and sliced to make cells. On the other hand, amorphous silicon panels are made by a vapor-depositing process. Solar cells are the main resource needed
Cons
- super expensive
- can cause pollution
- materials are hard to find
- requires space
- access to sunlight is limited
- storage is expensive
- hazardous waste
Pros
- generally doesn't cause pollution
- renewable
- sunlight is abundant
- available anywhere on Earth
- reduces electricity bill
- doesn't make noise
- conserves fossil fuels
Who Sells Solar Panels
Buying Solar Panels
Solar panels where thought of in 1839 by Alexandre Edmond Becquerel. He claimed, "Shining light on an electrode submerged in conductive solution will create an electric current." and sadly his idea was very inefficient. Around 100 years later, in 1941, a man named Russel Ohl invented solar cells and completed Becquerel's dream.
A lot of different companies sell solar panels,
but here are some that you may know.
Russel Ohl
They may seem expensive at first, averaging at about $50,000 for a 6.25-kwh system, but if you want to earn your money back and have them start paying you then solar panels may be for you. After an average of about 13-14 years in Texas your solar panels will start paying you.
