Renewable Energy

What is solar Energy?

Solar energy is the radiant light and heat from the sun that has been harnessed by humans since ancient times using a range of ever-evolving technologies.

Why do we us Solar Energy?

Because its cleaner energy.

How we use Solar energy?.

Solar power technologies provide electrical generation by means of heat engines or photovoltaics . Once converted its uses are only limited by human ingenuity

When did we start using solar energy?

Recently Over the past 20 to 30 years.

How Do we make Solar Energy?

Take a few modules of crystalline silicon.
Apply a soldering flux to each module
Clean the modules using ultrasound in 60F water
Solder the clean modules into rows of 9 x 4
Use flux and great dexterity
Verify each module with a voltmeter
Well, there's a bit more to it than that. Why don't you look at the excellent video on Youtube. See the link below.
You would need individual solar cells (too complex to make yourself). To make a solar panel, you would wire then in series or parallel. It's not very cost effective at this time to use solar panels for home power. The initial cost is high for the panels, storage batteries, and inverter/regulator. (Wipedia the free encyclopedia)
