200W PowerFlex CIGS based flexible solar PV panels (FG-4BT-200W)
Model Option:185W.200W.275W
Technology
Our flexible solar panel adopts CIGS technology, which has an aperature efficiency as high as 17%, rivaling that of rigid glass panels.
General production process
We begin with high-grade stainless steel foil and use an advanced semiconductor deposition process, PVD, to produce the most controlled, stable, and powerful flexible stainless steel CIGS cell in the world. Once the cell structure is deposited on the foil, special transparent conductive oxides are applied, and a specialized plastic-cell interconnect mesh-wire system is laminated to the cell, which is in turn protected by special water barrier plastics. The transparent water barrier is key to the longevity of the Flexi module series. The special plastic backsheet has an internal aluminum film to prevent water transmission from eroding the powerful stainless steel CIGS cells.
Benefits:
-Light weight:
Less than 2.4 kg/m(<0.5 lb/ft). Because flexible solar modules are so much lighter than heavy rigid silicon panels mounted with racks, they are best solution for building structures with low dead load and environmental load limitations(such as snow).
The modules are also ideal for other structures, such as autos, trucks, and RVs, that are not constructed to support the weight of traditional solar panels.
-Powerful:
Flex modules are the highest efficiency flexible thin-film CIGS modules in production today, with aperature efficiencies as high as 17%, providing over four times the power generation per kilogram of silicon.
-Easy to install:
Flexible solar modules are peel-and-stick application. This eliminates penetrations into the structure, reducing the chance of leaks.
Peel-and-stick application also allows for installation on surfaces such as autos, trucks and RVs where racks would not feasible, and lowers the balance-of-systems (BOS) costs and complexity when mounting FLEX modules on rooftops.
-Flexible:
FLEX modules conform to curved surfaces, enabling solar power generation on surfaces not suited to traditional rigid silicon panels.
-Resistant to Natural Disasters:
Flexible solar modules are thin (2.5mm) and adhere directly to surfaces, providing excellent wind and seismic resistance.
The modules are also shatterproof, and won't break if struck by debris.
-Reliable:
Flex solar modules' unique redundant interconnect design enables industry-leading reliability.
Advantages of CIGS
1.Strong Light Absorption
CIGS PV draws on the best characteristics of copper, indium, gallium, and selenium. It absorbs light over the widest spectral range, not only within the visible light spectrum in the same manner as crystalline silicon and amorphous, but also absorb light in the infrared range, from 700-1,200 nm. This means that CIGS PV can capture light for a longer period of time during a given day, a crucial advantage for high latitudes and altitudes where sunlight may be limited, or for short winter days.
2.Stable Energy Generation
Crystalline silicon PV exhibits light diffusion and photo deterioration when exposed to the sun for long periods of time, thus causing their power generation capability to gradually decline. CIGS PV does not suffer from these phenomena. Thus, from the long-term perspective, CIGS PV offers more stable energy generation and requires less maintenance costs.
3.High Transfer Efficiency, High Overall Electrical Output
According to the National Renewable Energy Labs (NREL), CIGS PV can currently attain up to a 19.9% efficiency rate. However, the highest rate recorded in the industry has been up to 16%, with an average rate of 12%. It is worth noting that when crystalline silicon (efficiency of 16%) and CIGS are tested together outdoors, the latter generates 1.2 times more energy than the former. Even though the current in use CIGS PV's efficiency be lower than that of silicon-based, CIGS PV absorbs more sunlight per day and so produces more energy in total.
4.Low Production Costs
The main cost of CIGS PV lies in its raw materials-copper, indium, gallium and selenium. However, it requires only ordinary soda glass as opposed to special ultra-white or thin-film conductive glass. While the aforementioned metals are precious metals, CIGS PV requires no more than a 3 um (1 um = 1/1000mm) coat, giving it a competitive per unit cost.
5.Short Energy Payback
Time Renewable energy offers many benefits. However, manufacturing the technology to produce such energy is itself resource-intensive. Thus, in assessing whether a particular type of renewable energy is genuinely sustainable, one needs to look at not only its efficiency but also how long it takes for the renewable energy produced to offset the resources needed to produce that facility. This is known as "EPBT"(energy payback time). According to the U.S. Department of Energy, assuming a 30-year lifespan for solar installments, the EPBT of crystalline silicon PV has been estimated to be about 2-4 years. By contrast, CIGS PV is estimated only 1-2 years. In other words, any of the PV systems above mentioned would have a roughly 26-29 year lifespan of truly pollution-free use. In a nutshell, CIGS comes out on top.
