KYOCERA Solar Modules Deliver Reliable Performance After More Than 25 Years in the Field
Case studies demonstrate exemplary product quality and long life
December 14, 2011In recent years the solar energy market has seen extensive growth and undergone massive change. With so much fluctuation in the market landscape it becomes increasingly difficult for end-users to know where they can place their trust; particularly concerning a major purchase like solar energy which requires a long-term return on investment. Kyocera Corporation (President: Tetsuo Kuba) has been a pioneer in solar energy technology for more than 35 years, and is known for the outstanding quality of its solar modules. Furthermore, the company boasts a number of real-life installations that have been consistently producing electricity for more than 25 years. These installations provide evidence of the exemplary reliability of Kyocera modules — a track record of both Kyocera's commitment to the market and its reliable product life.

Two aspects of major importance for any solar module are energy conversion efficiency and product life. As a pioneer in multicrystalline silicon solar cell manufacturing technology with one of the highest conversion efficiency rates in the industry, and with a longer track record than the vast majority of market players, Kyocera points to a number of case studies from around the world which demonstrate its modules' long product life and quality.
|1.||In 1984, Sweden's first grid-connected photovoltaic system was built in Stockholm. Since its installation, the façade-mounted 2.1kW system has been continuously and reliably providing the residents of an apartment building with environmentally-friendly electricity. The modules' average annual power generation performance is still reliable — with no significant change since the system was installed 27 years ago.
|2.||Also in 1984, Kyocera established its Sakura Solar Energy Center just outside of Tokyo. At the time, the Center was equipped with a 43kW solar power generating system which to this day continues to generate a stable amount of power for the facility.
|3.||In 1985, Kyocera made a donation of a 10kW solar power generation system to a small farming village with no electrical infrastructure located at an elevation of 2,600m (8,500ft) in Gansu Province, China. In 1993, the area received electrical infrastructure, and the solar modules were moved to a regional research facility for clean energy, where after more than 25 years, they are still producing consistent levels of electricity.|
In the U.S., nearly all solar module manufacturers offer a product warranty of 20 years or more, but very few have been in business that long. When end-users are considering implementing solar energy at their home or business, it is important to factor in whether the product will indeed last as long as promised, and if the company offering the warranty will still be around to honor it. With long-term field results to stand on and over 35 years of solar research, development and manufacturing, Kyocera's track record provides end-users with confidence on both accounts.
