Buyer’s Guide
Solar panels use complex science to operate, so understanding solar power is a must before buying a set. Keep reading to learn about what to look for in your purchase.
Panel Type
There are three types of materials used to make solar panels: monocrystalline, polycrystalline, and thin film.
Monocrystalline: Panels made of this material are the most efficient. They have a high energy output and last a long time. However, they are the most expensive, stop working if any debris even partially covers the panel, and lose efficiency over 77 degrees Fahrenheit. Polycrystalline: This material is affordable and environmentally friendly, but it’s less efficient than other panel materials. Thin film: The use of film is an emerging technology, so it isn’t as readily available to consumers as the other two types. Thin film panels are flexible and lightweight, and temperature and shade have less effect on their performance. However, they are the least efficient out of the three types and are affected by snow and rain.
Energy Output
Solar panel energy is measured in watt-hours. This is the amount of energy it takes to use one watt per hour. The higher the watt-hours, the more energy a solar panel can produce.
Panel Size
Solar panels come in many shapes and sizes, though most are rectangular. Think about how much space you have for the panels, and purchase the right size and number to best fill that space.
Use/Installation
There are many uses for solar panels, including charging electronics and powering your house. If you’re purchasing a solar panel to bring with you on a trip, consider buying a portable one that doesn’t require installation. However, if you plan on using solar panels to power your home, you’ll need to have them installed on your roof, which will require professional installation and cost several thousand dollars.
How do solar panels work?
Solar cells have two layers of silicon sandwiched between two conductive layers. These layers are covered by anti-reflective glass to prevent any of the light from bouncing off and going unused. When light hits the cells, it causes the electrons to move, which creates electricity.
How long do solar panels last?
On average, solar panels last for 20 years. Because solar panels lose about 1% of their efficiency every year, you’ll want to consider switching them out after they reach 80% efficiency.
How do I clean my solar panels?
Dirt, bird droppings, and other debris on your panels make them less efficient, so you’ll have to routinely clean them. Before cleaning them, read your manufacturer’s manual for specific instructions. If your manual doesn’t provide cleaning instructions, follow these basic guidelines:
Use a garden hose to gently spray the glass with water to remove debris. If you don’t have a garden hose, fill a bucket with warm water and gentle soap, and use a cloth or sponge to lightly wipe debris off of the glass.
