I'm curious- how does the response curve change in sunlight to enable charging of the 1.2V battery?

Michael Ossmann said...


In full sunlight, the crystalline silicon panel can produce current at more than 1.2 V. The curve is shaped the same, but the open circuit voltage is perhaps 2 V and the short circuit current is more than 1 mA.

is an Honor to share this testimony about Timo Spell that changed my life for good. It all started when I lost my job and I was down financially and emotionally because I couldn’t be able provide for my family and staying home all day Jobless it’s not easy, until when I saw a series of testimonies hearing people winning the Powerball lottery, I didn’t believed, but being poor no job you have no option. I gave it a try and I contacted Him and he told me what I have to do before I can become a big lottery winner and I accepted. He made special prayers for me in his temple and gave me the required numbers to play the lottery game and when I used the numbers to play it, I won a massive $1million Powerball jackpot. I was so happy and I chose to review my winning on any platform, I would love other people to seek his help you can also Reach him on Instagram page: @timospell0 He will give you the winning ticket number?? and exact location address in your country and where you will play the lottery game. Reach her on Email: or WhatsApp:+1 (845) 207-8532
