ADAFRUIT EARTH DAY SOLAR SALE! $20 solar panels! 2W solar panel 6V, 330mA out #earthday
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.
Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.
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?
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.
