One of the most popular DIY options is to purchase a solar panel kit from Grape Solar, an Oregon-based solar panel manufacturer whose products are for sale at Costco and Home Depot.

For those looking for the most efficient solar panels for their PV system, the first thing you need to know is how to compare efficiency metrics for different manufacturer brands. Simply put, efficiency (expressed as a percentage) quantifies a solar panel’s ability to convert sunlight into electricity. Given the same amount of sunlight shining for the same duration of time on two solar panels with different efficiency ratings, the more efficient panel will produce more electricity than the less efficient panel.
In practical terms, for two solar panels of the same physical size, if one has a 21% efficiency rating and the other has a 14% efficiency rating, the 21% efficient panel will produce 50% more kilowatt hours (kWh) of electricity under the same conditions as the 14% efficient panel. Thus, maximizing energy use and bill savings is heavily reliant on top tier solar panel energy efficiency.

When homeowners are considering solar offers on the EnergySage Solar Marketplace, we often hear questions about a solar panel’s manufacturer origin and whether it’s a good idea to choose Chinese panels for an installation. This is a common question as the latest estimates indicate that China is manufacturing roughly 70% of the world’s solar panels today – a dominant market share and a clear indicator of China’s key role in the global solar industry. China has a significant impact over worldwide solar trends like pricing, warranties and manufacturing practices. For example, the 80% decline in worldwide solar prices between 2008 and 2013 occurred largely due to improvements in manufacturing costs in China. And because China is such a major player in solar, many U.S. homeowners are asking “should I choose Chinese solar panels and will it match the quality of other top brands?” In this article we’ll break down pricing, quality and brand influence of Chinese solar panels.
