Top Producers of Solar Panels

Solar panels are one of the leading alternative energy solutions on the market today. 

They offer the consumer the chance to save money for a life time, and a chance to help the eco system.  

They are sold in many different stores, both online and brick and mortar stores.

If you are looking for a way to help our environment, and lower your bills, this is the way to go.

Thanks to the innovative and creative design techniques employed by solar energy companies, the price of panels are dropping. 

With so many different companies competing to make the best possible solar cell, in the end everyone wins. 

In this article, we are going to go over the top producers of solar modules(just another name for panels).

First Solar

First Solar, Inc. is an American manufacturer of thin film photovoltaic (PV) modules, or solar panels, and a provider of PV power plants and supporting services that include finance, construction, maintenance and end-of-life panel recycling.

Yingli Solar Panels

Yingli Green Energy manufactures monocrystalline and multicrystalline solar PV modules.

Yingli has experience across the entire PV value chain, from polysilicon production to the assembly of modules.

Its two primary solar module product lines are the monocrystalline PANDA Series and the multicrystalline YGE Series.


Yingli Solar’s PANDA product line was developed through the in-house collaboration between the Energy Research Center of the Netherlands (ECN) and Amtech Systems, Inc., two of the world’s leaders in solar power technology, to create a new, highly efficient solar cell.

PANDA modules use n-doped silicon instead of the industry’s standard p-type silicon, allowing a more efficient conversion of infrared light into electricity, and lower initial degradation rate.

As the PANDA product line achieves performance ratings of up to 16.5%, one of the highest in the world, it is best suited to commercial or residential applications where maximum energy output is essential due to space constraints.


Yingli Solar’s YGE Series is its flagship product line.

These multicrystalline modules are claimed to have efficiencies of up to 15.4%, and are used widely across commercial, residential, and utility-scale projects.


Yingli Solar’s manufacturing facilities are located in Baoding, Haikou, Tianjin and Hengshui.

Yingli Americas, a regional subsidiary of Yingli Green Energy, operates a regional research and development lab, the PV Testing Lab (PVTL), in South San Francisco.

The PVTL conducts extensive product characterization and quality control testing, and provides customers with sophisticated system modeling support.

SunPower Corporation designs and manufactures high-efficiency crystalline silicon photovoltaic cells, roof tiles and solar panels based on a silicon all-back-contact solar cell invented at Stanford University.

SunPower Corporation is publicly traded on the NASDAQ as SPWR (formerly SPWRA and SPWRB).

SunPower Corporation is a component of the Dow Jones Oil and Gas Index DJUSEN.

SunPower 125mm-wide single-crystal silicon solar cells are based on a rear-contact design that eliminates front-side metallization, maximizes the working cell area, eliminates redundant wires and makes automated production easier.

Forming the junction at the rear of the cell, combined with a clever surface treatment, allows it to trap much more of the available photons into mobile electrons—yielding a jump in efficiency.

The cell employs several other tricks to boost efficiency, including an oxide passivisation layer on the backside to deny regions for unwanted hole-electron recombination.

On June 23, 2010, SunPower Corp announced that it has produced a full-scale solar cell with sunlight to electricity conversion efficiency of 24.2 percent at its manufacturing plant in the Philippines.

This is a new world record, confirmed by the U.S. Department of Energy's National Renewable Energy Lab (NREL), for large area silicon wafers.

Hanwha SolarOne
