Crystalline photovoltaic (PV) panels are considered to be an older technology in the PV industry. The next, or 2nd generation, in PV panels are copper indium selenium (CIS) panels.

Solar Frontier is the top CIS producer in the world. Based out of Tokyo, Solar Frontier is a subsidiary of Showa Shell Sekiyu, which has more than 110 years of experience in energy and more than 30 years of experience in solar. The company houses offices in Tokyo, Munich and Santa Clara, California.


CIS modules provide greater energy harvest than crystalline modules. This is because of the crystalline’s vulnerability to real world conditions. CIS panels are also less sensitive to variables such as shade, low-sunlight conditions and degradation in performance due to temperature.

Credit Suisse, a world-leading financial services company, published an independent study testing panels made by 10 companies — Kyocera, Itogumi Motech, Suntech Power, Kaneka, Mitsubishi, Canadian Solar, Panasonic, Solar Frontier, Yingli Green Energy and Sharp. The data, which spanned a 12 month period in three different locations, revealed superior performance by Solar Frontier CIS panels in 10 of the 12 months! Solar Frontier CIS panels are able to absorb a wider range of light wavelengths than crystalline silicon (solar cells). And, as a result, Solar Frontiers continue to generate electricity in the early morning, late afternoon and during overcast days when conditions are less than ideal.


In comparison to other thin-film PV panels, Solar Frontier modules possess unique qualities. The panels are environmentally friendly and leave a smaller carbon footprint than crystalline, since they are lead-and cadmium-free and require fewer raw materials and production steps to manufacture. Solar Frontiers’ unique “light-soaking effect” also boosts output after installation by up to 10 percent. Another absolute benefit for island homes is that Solar Frontier CIS panels have been certified for salt mist and ammonia resistance by TUV Rheinland.
