Solar panel efficiency refers to how effectively a panel converts sunlight into usable electricity. Higher-efficiency panels generate more power in the same amount of space, making them a smart investment for systems where space is limited. When comparing products to find the most efficient panel possible, it’s helpful to know what features and technologies directly impact your panel’s efficiency. Keep reading to learn more.
Monocrystalline Cells
The type of solar cells used in a panel is one of the biggest factors in efficiency. For starters, monocrystalline panels are generally the most efficient option for a residential system, because their cells are made up of a single silicon cell each. This allows for electrons to move more freely through the cell structure for higher efficiency. (Note that the alternative is a polycrystalline panel, which has cells made up of many silicon cell fragments.)
N-Type Cells
For even greater efficiency and performance, premium panels may include N-type cells. These are created by adding an element to the silicon like phosphorus. This has more electrons than silicon and creates extra electrons, leading to higher efficiency, longer lifespan, and better resistance to degradation. So, for peak efficiency, look for N-type monocrystalline panels.
Half-Cut Cell Architecture
Half-cut solar cells are another feature that can boost efficiency. By cutting each cell in half, you can reduce the electrical resistance and heat loss in the cells—both things that cut into your energy production. These panels also perform better in partial shading, because each side has some ability to operate independently.
Anti-Reflective Glass
Not all the sunlight that hits your solar panel is absorbed; some of it actually gets reflected away and isn’t captured by the cells. Panels with anti-reflective coatings or textured glass surfaces can greatly cut down on these losses, allowing more light to enter the solar cells. This is especially helpful in early morning and late afternoon when the sun is at a lower angle.
By prioritizing these kinds of features when buying your solar panels, you can get more power from every panel on your roof. While you don’t need all of these features for an efficient Mission Solar panel, the more you can get, the better the panel’s performance will be. Speak to a solar professional to learn more about how to find a highly efficient solar panel that fits your needs and is compatible with the rest of your solar power equipment.
