To decode which of the hundreds of solar panel manufactures is the best, requires first for one to answered what one is trying to achieve? The simple answer is that the best warranty, the highest efficiency, and best performing solar PV panel from a known manufacture is unquestionably the best. But not everyone may need the best! If a system of average panel efficiency will still produce all the electricity you need and fit in your limited space, perhaps saving some money on the cost is more desirable than buying the best. Or perhaps the best for you is a solar shingle system that blends right into your roof, or perhaps the most efficient panel as you have limited space.
What about Buying American made solar PV panels vs. foreign panels, are they better? Solar panels like all consumer goods come in a varying degree of quality, efficiency, warranties, and manufacture stability. Like automobiles, today many components come from countries all over the world so knowing only where something was assembled does not tell the whole story. If one finds a solar panel that meets the US content rules then an addition 105 of tax credit is available to the consumer.
“The best” is not always the simple answer as many variables play into the equation. My belief is that you buy the lowest efficient panel that provides all the power you need in your limited space from a manufacture that is well capitalized and has a proven record.
