Our third Solar Power My Project Contest winner from Whistler, BC has "a mesh network of XBee/Arduino nodes that report battery voltage of their respective solar power systems. Of the 20 nodes, 2 are currently...
Our second winner of our "Solar Power My Project" Contest combines three of our loves: solar, bicycles, and espresso. Brian Del Vecchio and other friends of Alessandro are going to upgrade his custom...
We've selected our first winner in our Solar Power Your Project Contest. Logan is building an automated garden powered by an Arduino. The system is designed to sense water level moisture. When water level...
To celebrate the launch of our new 6 Watt solar panel, we are announcing a new contest. We are giving away five 6 Watt kits to DIY-ers looking to take their Arduino, remote sensor or any technical project off...
Ben Schapiro, a Chicago-land customer, took our 16 Watt solar panel and a classic tackle box and made a pretty cool and versatile solar charger. The solar panel charges a deep-cycle lead acid battery plus our...
Two customers recently took our 7 Watt Solar Charger Kit (we recommend our 9 Watt Kit as an updated alternative) on a hiking tour across Northern Norway, Sweden and Finland. They used the kit to charge their...
We've been working with a company called Cam-Do on how to power a GoPro camera for extended timelapse photography projects where battery life is a limiting factor. Our setup is now being used out on Jamaica...
A customer sent in pictures of his new laptop solar charger kit in use in the Indian Himalayas. He's using 3 of our 3 Watt solar panels to charge our V60 Laptop Battery and V15 USB Battery. Here's the...
Joseph DeLappe is starting a 460 mile bicycle ride through Nevada today. He'll be dragging home-made chalk behind him to draw a line around Nellis Air Force Base. This will create a 100 mile x 100 mile "area...
Mount over 60 Watts of solar panels on the back of a circa-1987 Dave Scott Centurion bicycle and you get a pretty powerful phone, tablet and even laptop charging system. We built this in celebration of NYC's...
We left the house a bit earlier than usual today to support NYC's Bike to Work Day in our own solar-powered way. We decked out our usual commuter bicycle with 60+ Watts of portable solar panels, 180 Watt hours...
20 students at UW-Madison recently built a solar charger as part of IEEE Student Projects. The goal of the program is to provide students hands-on experience with practical design skills as many of the...
We really enjoyed working with LifeEdited to provide backup solar power for their compact New York apartment. So when Graham Hill (the Founder) asked us to help with a more ambitious project, to provide off...
We have been working for some time on our latest product, the USB Touchlight. This is a super bright, USB-powered LED light, designed to run from our solar batteries. When our good friends at Life...
We did a solar Lego car post a while back. It turns out the newer lego motors, the M-Motor 8883 and 8882 are a tiny bit more complicated than the older motors. They have a wire with 4 leads instead of 2. By...
Nicola from Italy just sent in his hack of the IKEA SUNNAN solar lamp so that it can charge his electronics. He increases the power to the lamp's batteries using Voltaic's 2 Watt solar panel and uses...
After Sandy, we deployed and installed hundreds of solar phone chargers and light systems. We mounted a 3.4 Watt solar panel outside using double-sided sticky tape and connected it to our V11 USB Battery...
Solar Panels for Lead Acid Batteries Lead acid batteries have large capacities and are often available in many places around the world. But which lead acid battery should you use with solar panels? I...
