I take no pride in writing this blog post about discount solar panels because no matter how hard we try to persuade our customers to look past cost, by and large, they are not convinced. In the last several months, the single most important criterion for our customers in purchasing home solar panels is price. There are numerous ways to differentiate solar modules. We have even introduced a solar panel comparison to alert you to significant differences in the panels that we sell. Of course, the essential difference is expected output, and you will want to look at efficiency and the PTC rating (PVUsa Test Conditions) to come up with an estimate of what your solar panels will produce over the life of the panels. There are other parameters that you may want to consider, such as size and weight. Aesthetics, that is the look of the panels, is no small matter if you live in a trendy area and your southern facing roof is visible from the street. But as we have been looking at the results from the past several months, we have noticed one unmistakable trend: our customers love low cost panels.
