Best Solar Panels 2019

 

What is Solar Panel?

Although standard definition of solar panel is not available however solar panel could be defined as electronic device comprising of photo voltaic cells that produce energy directly from sun light. Certain materials can be made to produce electricity when light falls on them; this is called the photovoltaic effect. Solar panels use this effect to convert energy from sunlight into direct current (DC) electrical energy. An inverter unit then changes this into alternating current (AC) for your home’s electrical circuits. Any excess energy could be stored to battery banks or you can sell to local commercial power utility company to earn money.

Most solar cells are made of silicon. Solar panels, also called modules, are each made of several solar cells, connected together and sandwiched between protective glass and a backing plate, the whole panel usually surrounded with an aluminum frame. Solar panels work best when they’re south facing in USA, Following points are the most important to get optimum output from solar panels.

  • Solar Panels should directly face the sun,
  • Optimal angle should be achieved to get maximum output
  • Sunlight should not be blocked by trees or shading.
  • Weather is also an important factor in solar panels output.
Types of solar panel

These most commonly use traditional types of solar panels are monocrystalline silicon, polycrystalline silicon and thin film amorphous

  • Mono crystalline silicon Solar Panel considered most efficient
  • Polycrystalline Solar panel
  • Thin Film
Why Solar Energy

Here are some good reasons for using solar energy to power your home.

  • Reduction in Commercial Power Expense
  • Renewable energy source
  • Green Energy
  • Low Maintenance Cost
