Technological advances have transformed the solar energy industry in recent years. Solar panels are significantly more efficient, producing more power in the same amount of space. Meanwhile, prices continue to fall, reducing the cost of solar electricity. But with the introduction of new technologies comes uncertainty. Which solar panels are the most reliable and durable? What technology creates the least amount of pollution in the manufacturing process? Let’s explore some of these critical issues in the pursuit of the best solar panels on the market. Solar Panel Considerations Efficiency Solar panels have become significantly more efficient in recent years. And the more efficient a solar panel is, the more energy can be generated in a given space. Space becomes more critical when there are constraints due to the size or your roof or property. Unfortunately, more efficient panels typically cost more. If space isn’t an issue, efficiency becomes less crucial. For installations limited by space, panel efficiency is an important consideration. It is also important to consider the long-term efficiency of solar modules. Long-Term Power Generation Like most other things, solar panels degrade over time. They become less efficient in turning sunlight into electricity. This is important because solar panels can last 30 years and you want your solar system to be churning out a lot of energy a couple of decades from now, even if someone else owns the home. Solar panel manufacturers offer a power production guarantee to ensure a certain level of output over a given time. Many solar panel manufacturers provide a guarantee of 90 percent production for 10 years and 80 percent for 25 years. Read More... Image Credit: Nichole McClure |
