How Solar Panels Work: Everything to Know


Solar energy is the harnessing of the sun’s power to create electricity or heat. Solar panels convert sunlight into DC (direct current) electricity, which can be used in your home or business, or fed into the electrical grid. Read to know more if you want to purchase solar panels direct.

The process of converting sunlight into usable energy is called photovoltaics (PV). PV cells are made of semiconductor materials like silicon, which, when hit by photons from the sun, creates an electric field and voltage.

How do you know if solar is the right choice for you?

  • The best way to determine if solar is the right choice for you is to calculate how much sunlight your location receives throughout the year.
  • You can find this information on a solar map or with a solar calculator.
  • Once you know how much sunlight your location receives, you can determine how many solar panels you would need to generate enough electricity for your home or business.
  • Additionally, you can estimate your monthly electricity bill and compare it to what you would pay with a solar system.

The benefits of solar energy:

  • There are many benefits of solar energy, including reducing your monthly electricity bill, generating clean and renewable energy, hedging against rising energy costs, and contributing to a cleaner environment.
  • Additionally, going solar can increase the value of your home or property.

How much money can you save with solar energy?

The amount of money you can save with solar depends on a few factors, such as the size of your system, the amount of sunlight your location receives, and the current cost of electricity. However, many homeowners see a return on their investment in as little as 5-10 years.

The environmental benefits of solar energy:

The environmental benefits of solar are vast.

  • Solar power doesn’t produce emissions or pollutants like other forms of energy generation, such as coal or natural gas plants.
  • Solar also takes up less space than traditional power plants, so it doesn’t require large amounts of land that could be used for other purposes, like agriculture or housing developments.
  • And finally, when people go solar, they reduce their reliance on fossil fuels and help move us towards a cleaner energy future.

How does your location affect your ability to go solar?

Your ability to go solar depends on several things: how much sunlight your location receives throughout the year (which you can find on a solar map), whether your home or business is connected to the electrical grid, and local incentives and rebates available in your area. If you meet all of these requirements, then going solar is definitely an option for you!

The different types of solar panels available:

Currently, there are three types of commercially available solar panels: monocrystalline silicon panels, polycrystalline silicon panels, and thin film panels.

  • Monocrystalline silicon panels are made from a single piece of silicon crystal and are more efficient than other types of panels.
  • Polycrystalline silicon panels are made from multiple pieces of silicon crystal and are less efficient but less expensive.
  • Thin film panels are made from thin layers of semiconductor material and are less efficient but more affordable than monocrystalline and polycrystalline silicon panels.


Installing a battery with your solar system is not always necessary or cost-effective; however, it may be something to consider if you live in an area with frequent power outages or want to store extra energy for later use. Talk with a qualified installer about what would be best for your specific situation.
