Buying Guide
When looking to buy the best 120 watt solar panel, there are a few key features to consider. We’ve used and tested a variety of panels, and here are some factors to keep in mind:
Power Output
The power output of a solar panel is the amount of energy it can produce in a given amount of time. For a 120 watt solar panel, this should be around 120 watts of power. However, it’s important to note that the actual power output can vary depending on the panel’s efficiency and the amount of sunlight it receives.
Efficiency
Solar panel efficiency refers to how well the panel can convert sunlight into usable energy. A more efficient panel will produce more energy from the same amount of sunlight. Look for panels with high efficiency ratings, but keep in mind that this can also drive up the cost.
Durability
Solar panels are designed to be durable and long-lasting, but some panels are more durable than others. Look for panels with sturdy frames and high-quality materials that can withstand harsh weather conditions and maintain their performance over time.
Size and Weight
The size and weight of a solar panel can impact its portability and ease of installation. If you plan to move the panel frequently or install it in a remote location, look for a lightweight and compact design that is easy to transport.
Warranty
