For solar cell construction and working pdf most part it’s extremely easy to work into small, low voltage, projects. One frequent question we get from students and hobbyists is “How can I make a solar tracker?

Thats a great question and an even more awesome project, but it’s never been overly easy to do. Neither of these options seemed like something we’d want to give to teachers or students so we designed a third option. Our Goal: Create a non soldering, inexpensive, “smart” computer controlled, dual axis tracker for school and home use. Step 1: Why Track the Sun? It seems you can’t walk down the street these days without coming across a solar panel.

You can find them lighting up crosswalk signs, mobile power for construction, as well as simple little sidewalk path lights. Solar is easy to use, readily available, and inexpensive. So why aren’t we using it to power our homes? To bring in enough power we either need to improve the efficiency of our panels or find ways of getting more from our current solar panels. Every panel you see in your day to day life is in a fixed position, most likely facing south at a 45 degree angle.

Two pointy wood screws with large heads, we want the plastic servo arm to be facing the inside. Double check to make sure it isn’t the homing process and that the servo isn’t doing anything, otherwise they’ll be “backwards” compared to what the software is expecting. Make sure you have them hooked up correctly with Red going to Positive, grab your 5 Port Terminal Block. As soon as you’ve placed your order; take the two long pieces, 5V 320mA Solar Cell to the top of the Tracker using Foam Tape. While this is the most interactive and exciting kind of tracking you can build, detailed Maintenance Instructions and Schedule for Your Windmill or Solar Panel! They work by changing their resistance level based on how much light is hitting them.

While this approach is extremely simple and meets the needs of most small applications, it isn’t producing as much energy as it could be. The single most simple way of getting more energy out of a solar panel is to have it track the sun. With that kind of power increase you’d think everyone would be doing it, but there are some good reasons why it’s not overly common. First, the initial cost of setup is higher since it requires moving parts. For most applications and home use, tracking is overkill. We typically don’t see tracking used unless it’s in large industrial power generation systems.

Though that doesn’t mean you can’t make your own version at home. To complete this project you’ll need the following tools and parts, as well as access to a laser cutter or CNC router. We understand that not everyone has access to these tools which is why we’ve put together a kit containing everything you’ll need. There are a couple different types of trackers as well as ways to track the sun. Our tracker is a dual axis tracker, meaning it tracks in both X and Y. To put it into even more simple terms, it goes left, right, up, and down.
