After that I did the 3 batteries in a (semi-) professional charger AccuPower IQ-128 (identical to the here - often acclaimed BC-700 - to the right) down and started the test program to determine the capacity. Result: the capacity amounted to 856 or 948 or 1007 mAh.
Although this capacity compared to the indicated 900 mAh are ok: the difference of 15% between the strongest and the weakest battery not just talking about high quality of the batteries!
Next, I have 3 (almost) empty Sanyo Eneloop placed (1900 mAh) in the solar module, open circuit voltage 1.02 to 1.04 volts. After 3 pretty gloomy days of January with a total estimated about 2 hours of sunshine had 3 Eneloops an open circuit voltage 1.16 to 1.17 volts. A very decent value, I mean.
For solar module: this has an effective solar cell area of 7 cm x 10.5 cm, the performance is specified with 1 Watt. Whether that is the determined under normal conditions value in watts (peak), goes from the user manual (in German, French, English and Dutch in paper form supplied) is not apparent. The power rating equivalent to about 136 watts per square meter - a value, which is customary for solar cells on rooftops (as Watt_peak).
By the way you can - contrary to what other reviewers - connect 1 or 2, or all 3 LED lamps.
Fixing: many options, including the option of the solar module to a pole, banister, garden fence post, etc. with up to 8 cm in diameter to be screwed (!). Both the solar module and the 3 LED lamps can be by means of locking ball joints (helical, ie no screwdriver needed) align flexibly. These joints can turn not only to the supplied ground spikes or fixing plates screws, but also disassemble (for this you need a screwdriver), so that the craft possibilities are practically no limits. Small drawback: the 4 earth spikes are only 10 cm long. The lamps that's ok, but the solar module must make sure that no shadow falls on it (not even a small part of the area, otherwise the module does not perform!), So that the spike for the solar module, for example, the (North -) edge of a lawn is used meaningfully only briefly held lawn.
Suitability for 'wilderness': in principle, the solar module can also use to load 3 AA batteries if you have no electricity for weeks. A reasonable mounting example on a backpack should - with a little tinkering - not be a problem. The weight corresponds to about a 5-inch Navis or a 6-way power strip, so just about acceptable, I mean. Drawback, however: the external battery pack such as for reloading Navis / smartphones / handsets need 4 AA batteries (in 3 ranges, the voltage for charging is not), so you "juggle" with the batteries must - and in a way that in the battery pack Only batteries of the same voltage as possible (and of course also possible the same capacity) come (to avoid transient currents and therefore premature aging of the battery). Not ideal, this approach - but due to the high performance and quality of this solar module I would take it for a longer trip away from civilization yet.
Overall, a good product; the 5 star it would get me in better batteries, such as Sanyo Eneloop LSD or other (= low self discharging) batteries (which would make the product a total of only slightly).
