PVCompare.net is the first free platform made for users by users in order to address the problem of asymmetric information that has always characterized the energy sector.  Through the huge amount of data we have collected, we are now able to provide you with some insights. For this research we resorted to our 35,000 outputs from as many plants around the world, isolating only those from the US territory. We did not set tilt or orientation, but we made the comparison in absolute terms. The comparison is based on the historical production data we detected in the year 2014. Therefore at the end of this year it will be a possible amendment of the current ranking.

Who is the best manufacturer in the US?

Obviously we understand that given the vastness of the territory, and the climatic differences from area to area conjugated to possible technical differences the answer to this question is impossible, only with the use of our tools for more focused research may have more answers certain. So what we did was to extrapolate the plants with the best outputs, let's check.

Overview of the US PV-Market:

According to the Solar Energy Industries Association and GTM Research, US reached a record of 6,201 megawatts of newly installed solar photovoltaic capacity in 2014, growing 30% over 2013’s total. 32% of the US new generating capacity in 2014 is solar energy: doing better than wind energy and coal.

Let's see which have been the best manufacturers of photovoltaic panels in 2014 according to our data:

  1. Sharp Corporation has built its credibility upon its long history of solar development: Sharp has put efforts in research and development since 1959. These efforts have led to ground-breaking solar solution. Starting from 1959, when the founder Tokuji Hayakawa started developing solar cells, Sharp has achieved many different successful results: it also contributed to the development of the solar cells that power the satellites in Japan’s national projects. Sharp’s solar business spans across the globe: Europe, US, Middle East, Asia and Oceania. This producer is placed in first position in the year 2014 with an efficiency of 1517 kWh/kWp. This pv-plant is located on Grain Valley , System size of  5760 Watts with Enphase as inverter

  1. Canadian Solar Inc. (NASDAQ: CSIQ) operates as a global energy provider with successful business subsidiaries in 20 countries on 6 continents. Besides serving as a leading manufacturer of solar PV modules and provider of solar energy solutions, Canadian Solar has a geographically diversified pipeline of utility-scale power projects. With the company’s recent acquisition of Recurrent Energy, Canadian Solar’s total project pipeline is now 9 GW, including an increase in the late-stage project pipeline to 2.4 GW. With state-of-the-art manufacturing facilities in Canada, China and Vietnam, Canadian Solar employs over 8,500 workers worldwide. This translates into more than 12 GW of panel shipments, or over 30 million PV modules, in the past 14 years.
  2. This producer is placed in forth position in the year 2014 with an efficiency of 1079 kWh/kWp.This pv-plant is located in Washington DC , System size of  16250 Watts with Enphase Energy as inverter
