ADAFRUIT EARTH DAY SOLAR SALE! $20 solar panels! 2W solar panel 6V, 330mA out #earthday

Solarpanel20W Lrg
We are having an ADAFRUIT EARTH DAY SOLAR SALE! For today only we’re going to sell our solar cells for $20, 2W solar panel 6V, 330mA out – they will never be this price ever again. It’s today only, sale ends 11:59pm ET 4/22/2010 – the price is usually $25 each. We have 400 of these ready to go immediately.

These panels come to us from Voltaic Systems, makers of fine solar-powered bags and packs. These are waterproof, scratch resistant, and UV resistant. They use a high efficiency monocrystalline cell. They output 2W solar panel 6V, 330mA out via a 3.5mm x 1.3mm DC jack connector. The substrate is an aluminum / plastic composite, specifically designed to be strong and lightweight. They can easily stand up to typical outdoor use including being dropped and leaned on.

  • Size: 4.4″ x 5.4″ / 135mm x 1150mm
  • Weight: 4 ounces / 120 grams
  • Cell type: Monocrystaline

Cell efficiency: 17% – To connect, we suggest a 3.5mm/1.5mm DC jack.

Get them today only for $20 each – in the Adafruit store.

  1. Hi, do the panels plug into / run with an Arduino Duemillanove? Regards, Thomas

  2. @t – of course, many ways to do it!

  3. Excellent! I plan on building one of these while waiting for the MintyBoost + to be completed:

  4. I’m curious about using one to power an Arduino on my bike. I realize there are many variables to consider, but (once fully charged) any idea how one of these would compare to running from a 9V battery?

  5. In my world, just about the only “green” I care about usually involves Ben Franklin and his co-horts. Still, it’s easy to appreciate a technology that isn’t just earth-friendly, but also saves plenty of those bills over time. I think aesthetics and cost are a big reason you don’t see more Solar technology in homes and businesses right now, and stuff like this can only help to bring the technology more into the main-stream. Pretty cool.
