Product Description
Based on CIGS technology, SUNLOAD solar panels have several major advantages compared with commercial
crystalline silicon cells: They can be embedded as a thin layer into a flexible plastic compound and due to this,
they are extremly light, flexible and practically unbreakable. They operate under a clear blue sky as well as in
weak or difused light and even if part of the cells are covered by items or external shadows (so called „partial
shadows).
Because of a high efficiency of CIGS solar cells you have a high power on a small area. The panel even supplies
energy under adverse conditions, for example in regions with less sunshine. Therefore, SUNLOAD solar panels are
ideal for mobile usage: very small and foldable, flexible, unbreakable and very robust: these panels sustain the
highest mechanical stress and was many times proven under hard conditions like Himalaya and Afrika.
SUNLOAD solar panels deliver power for all kind of electronic devices as notebooks, energy saving lamp, mobile
phones, smart phones (for example, iPhone), MP3-player, digital cameras, video cameras (accessories are neces-
sary), GPS, etc.
You are able to connect your devices with a suitable 12V car adapter (CLA adapter) directly, provided that the
operating parameters of the connected devices are compatible. We do not recommend this because of the
voltage range up to 30V. For the safe usage you should take a voltage limiter or a SUNLOAD MultECon Charger
to protect your equipment.
GENERAL NOTICES
The achievable power output of SUNLOAD solar panels depends on various factors:
Position of the sun
The lower the sun, the longer is the path of the solar radiation through the atmosphere - the lower its intensity.
Therefore, the power output of the module at lunchtime is clearly higher than during the morning or evening
hours, during the summer months, it will be stronger than during the winter months, and closer to the equator,
it will be much better than in the northern or southern hemisphere.
Alignment towards the sun
The so-called effective area is largest, when the folding module is always aligned exactly vertically to the angle of
incidence of the sun. Also with strong sunlight, the module output power is more reduced, the less the module
is aligned with the sun.
Weather
The output power of the module decreases as the cloudiness increases, i.e., even slight mist results in a reduc-
tion in yield. This reduction in power, however, is not anywhere near as serious as , for example, with crystalline
solar cells, which, even with the slightest cloudiness clearly produce less electricity.
Partial shading
With partial shading of individual cells or part of the solar panel , CIGS
solar panels do not lose their capability to generate electricity. For a
general assessment of the power reduction to be expected on average,
even shading, the following approximate values may serve:
