Interest in solar energy is on the rise. In fact, recent reports show that residential solar installation is up 46% over Q2 last year alone. The many benefits of solar power include lower utility bills, a renewable energy source, lessening dependence on fossil fuels, better for the environment, and so much more. There are so many interesting facts about solar power. Here are just a few of our favorites.

 

The Source of Solar Power

 

The sun is approximately 4.6 billion years old and is almost 100 million miles away from Earth. The Department of Energy states, “Solar energy is the most abundant energy resource on earth - 173,000 terawatts of solar rays strike the Earth continuously. That's more than 10,000 times the world's total energy use.” The Department further explains, “When the sun shines onto a solar panel, energy from the sunlight is absorbed by the PV cells in the panel. This energy creates electrical charges that move in response to an internal electrical field in the cell, causing electricity to flow.” Solar panels release no harmful emissions into the atmosphere and can be recycled when they lose efficiency.

 

Solar Panels

 

The two most common types of solar panels used in residential solar installation are monocrystalline and polycrystalline. They differ in efficiency, color, price, and composition. 

 

Monocrystalline:

  • Black Exterior Color
  • Octagon Shaped Silicone Discs
  • Average Efficiency - 15%-20%
  • Higher Price Point

 

Polycrystalline:

  • Blue Exterior Color
  • Made with Many Silicone Fragments
  • Average Efficiency - 13%-16%

 

When choosing the panel for residential solar installation, consider a premium system that produces greater energy and is more efficient over time.
