Does Solar Panel Size Play a Role?

The size of a solar panel can certainly make a difference. However, just because a panel is bigger, it does not mean it is better. The more important number to look at is the power rating. A comparable example would be batteries. A 9-volt battery is smaller than a D battery, but it still produces more power. The same can be true for solar panels. Also, as technology has advanced, solar panels have become more efficient while also becoming smaller in physical size.

If you have a larger usable roof area, buying more larger panels at a lower cost and reduced efficiency might be the way to go. If you have a limited roof area, then smaller, more expensive, and higher efficiency panels might be the way to go. In short, size does make a difference, but not in the way you might think.

After you answer the above questions, you will have a better idea of how many solar panels are ideal for your situation. There is no one-size-fits-all answer here.
