FAQ: Difference between the Poly and Mono solar panels?

Question: What is the technical difference between the 250Wp Poly and 250Wp Mono solar panels?

Answer: In fact there is not much difference. In 2014 the solar technology has progressed to same levels both for poly and mono types of cells, so that there is no significant difference between the technical specifications of these two panels. The only difference is visual: some customers prefer the mono panels, because the cells are of the same color and seem to look nicer. Also the black frame solar panels are usually made with mono type of cells, so black color panels are often mono.  On the other hand the poly panels are usually sold in higher quantities and the price for poly panels is little bit lower.  

Note: on internet, there are some older articles that discuss the differences between the poly and mono panels. In the past times the mono panels used to be more stable and more yield-efficient. Keep in mind that these articles and the tests were made usually several years ago. The results are no longer valid, because the modern panels have very similar performance.
