Solar Energy

Solar energy is the radiant energy emitted by the sun. It is a renewable and sustainable source of power that can be harnessed and converted into usable forms of energy such as electricity and heat. Solar energy is becoming an increasingly popular and viable alternative to traditional fossil fuels due to its environmental benefits and decreasing cost of solar technologies.

How does solar energy work?

The process of converting solar energy into usable forms of energy involves the use of solar panels, which are made up of photovoltaic cells. When sunlight strikes these cells, it excites electrons in the semiconductor material, creating an electric current. This current can then be harnessed and stored in batteries or used to power electrical devices directly.

Advantages of solar energy

• Renewable and sustainable
• Environmentally friendly - produces no greenhouse gas emissions
• Reduces reliance on fossil fuels
• Low operating costs once installed
• Can be used in remote or off-grid locations

Disadvantages of solar energy

• Intermittent - depends on sunlight availability
• Initial installation cost can be high
• Storage of excess energy can be challenging
• Dependent on geographical location and weather patterns
• Energy production may decrease over time due to panel degradation
