How to compare solar modules?

When evaluating solar modules, there are various aspects to take into account. The following are some important things to remember:

Efficiency: The percentage of sunlight that a solar module can convert to electrical power is called its efficiency. Modules with higher efficiency will generate more electricity per unit area.

Power output: A solar module's power output is expressed in watts. The module may generate more energy the higher its wattage.

Temperature coefficient: This describes a solar module's performance at extreme heat. In hotter climates, modules with a lower temperature coefficient will function better.

Durability: Wind, hail, and snow are some of the weather variables that solar modules are subjected to. Select modules with a high durability rating, particularly if you are in a region where severe weather is common.

Warranty: The normal duration of a solar module's warranty is between 10 and 25 years. Verify the warranty's specifics, such as its duration and scope of coverage.

Cost: Lastly, when comparing modules, take into account their cost per watt. Modules of higher quality and efficiency will usually cost more up front, but they can save you money over time.

You can compare solar modules and select the one that best suits your needs by taking these considerations into account.
