Solar panels are a popular product at the moment, and there are several variables to consider when deciding on a panel to purchase for your solar energy system. You’ll have to look at issues such as a panel’s quality and durability among other things. To assist you during the process, here is a guide to help your find the right panel for your system.

Check The Ratings
Each receives a power rating to explain the amount of power that they can produce. The majority of panels on the market have power ratings between 200-300 watts. The higher the power rating, the easier it is for a panel to produce a lot of power.
Panels are manufactured, which may lead to situations that could alter the power output. That’s why power tolerance is significant. Power tolerance helps explain how the power output of a panel may vary compared to its nameplate rating. A panel’s nameplate rating helps explain how much power a panel can produce under perfect conditions. Power tolerance is explained using a plus or minus percentage. Most people prefer a panel with a wide tolerance range.
While solar panels are able to function in the sun, high temperatures can damage a panel’s ability to generate power. Check the panel’s coefficient, which measures how often a panel’s power capacity decreases during days when the temperature is over 80 degrees. Research has shown that panels with lower coefficients are able to perform better for an extended period of time.
Solar panel efficiency explains how successful a panel is at converting solar radiation into electricity. The best panels have efficiency ratings over 20%. Panels with high efficiency ratings are able to produce more hours of energy per watt of power capacity. Efficiency is something that you should pay close attention to if you have large energy bills.
Manufacturer warranties are important, as they help give an idea of how durable and efficient the panel will be. Keep in mind that the amount of electricity that a panel can produce decreases over time. Look for a panel that can retain most of its production capacity over the first 10 years. Find a panel with a materials warranty that protects you in the event that the panel isn’t durable. Pay attention so that you can avoid having to pay for the potential shipping and labor costs. On average, most panels function properly for 12 years before anything goes wrong.
