SOLAR ENERGY

HOW SOLAR ENERGY WORKS?

• When light hits certain objects it turns into electrical energy.
• The solar panel converts those photons into electrons of direct current .
• Solar cells are called photovoltaic.
• Like other energys solar energy don't take water.
• The us is a massive power plant in the sky.

HOW COULD SOLAR ENERGY BE USED?

• Heat things, like houses.
• Turn light into electrical energy.
• Heat water.
• Helps reduce fabrication cost.

WHAT ARE SOME EXAMPLES OF ITS CURRENT USE?

• Hot water, warm pools.
• Ventilation
• Solar vehicles.
• Agriculture and horticulture.

WHAT ARE THE EFFECTS ON THE ENVIORMENT?

• Thermal plants.
• 3.5-10 acres per megawatt.
• No global-warming involved.

IS THE TECHNOLOGY WIDELY ACCEPTED TODAY?

• In the U.S had more than 3,500 megawatts.
• 350,000,000 terawatts of power is available form the sun
• Solar energy was founded 100 years ago.
• It takes 10 years 20% of homes use solar energy (in the U.S)
• The harnessing sun rays are harmless.

POSITIVES

• Don't create green house gases
• Don't pollute air/water
• Life span of 20+ years
• Easy to maintain, no moving parts
• Not difficult to install

NEGATIVES OF SOLAR ENERGY

• Needs proper recycling
• Large surface required
• High upfront costs
• Sunny area required
