Tested with 7-9V supply voltage, sufficient for the 5V and 2.5V Voltage. I tested the voltage with three multimeters and it seems "quite accurate". The supply voltage allows a wide range from 4.5V to 30V (not explixitly tested). I have no idea where to get the 15V battery. ANENG AN8008 (US$16.99) always displays a slightly lower voltage, e.g. 4.997V for 5V. DANIU DT832 (US$4.69) seems to be less acurate (e.g. around 4.98V for 5V) and displays a still lower voltage. I have two, measurements are always really close. Kopp GDT-190A showed 4.99V to 5.01V for 5V.

"10Pcs NRF24L01+ SI24R1 2.4G Wireless Power Enhanced Communication Receiver Module" is perfectly compatible with "1100 Meter Long Distance NRF24L01+PA+LNA Wireless Module With Antenna". Work really well if combined with a "no antenna version" (10Pcs NRF24L01+ SI24R1 2.4G Wireless Power Enhanced Communication Receiver Module). Sending and receiving only with the "no antenna version" covered a significantly smaller distance (in house compared to house plus garden and garage). Modifying the transmission power did not make a significant difference (hardly or not measurable). The best distance covered was below 50 meters including at least one wall. I don't think more than 100 meters will work with a normal setup.

A battery can be added. It actually starts to turn without strong sunlight. For artificial light a strong/direct light would be necessary. Negative: It is rather loud.

Panel is delivered without any extras (wires). Has rather high Voltage 1.8V with low light (artificial ambient light in my room). Measured up to 22mA and 6.7V with artificial light. Looks good for 6V nominal voltage. Negative: Protection foil was rather hard to remove.

Already tested some, fried one. Tip: do not connect to 12V on any port, not even for a second ^_^ I use the processors without the board and an additional 16MHz oszillator. They seem to work with a much lower supply voltage than documented for 16MHz (short time usage, I think I went down to 3V). Mind that the 1.1V-Reference seems to differ for different chips.

The panel doesn't look as perfect as in the picture - the inner cells have more distance and are slightly tilted. The performance is still good (compared to a smaller panel I own).

Quick tests confirmed 100-200 mA with up to 5V. Current increases with voltage. It will not run below 100mA. I recommend using a freewheeling diode and a 100nF ceramic capacitor when using with an Arduino or ATMega to avoid resets and computational errors. May induce noise if placed close to old speakers. No issues so far with other devices, except the connected ATMega328P.

Works. Can be tested by blowing. Rather strong winds are ncessary to activate the light.
