A Personal View: Simplicity in Solar

By Daniel Wilson, Senior Electrical Engineer at Sun Action Trackers

When I was younger and pondering the idea of going to school for engineering, I asked a very successful engineer what I should expect to learn from studying engineering at university. I expected something along the line of “you will be able to fix cars after you graduate” or “you will be better at math”. Instead he told me that I would see the world through a new set of eyes. It wasn’t until I graduated university that I understood what he meant. With fresh new eyes, I now saw the world through the laws of physics, cause/effect and that the most robust solutions are usually the simplest. A simple solution is by no means inferior, rather it simply accomplishes the same task as a complex solution, but in a more efficient way.

At Sun Action Trackers, we know that simplicity in PV tracker design is essential, as these systems will be operating continuously, outdoors for 25+ years. Our Single and Dual Axis trackers all utilize our patented Real-Time Sensor technology that searches the sky for the maximum point of irradiance. Why blindly follow the sun with a program that doesn’t even consider the fact that clouds are between the tracker and the sun, when you could just simply rotate where the energy is actually at? Real-Time sensing is simpler, gives you higher generation, and doesn’t ever need to be calibrated. Trackers have to move, so some type of bearing is integral to the system. Once again, in the spirit of making things simple through ingenuity, we have designed flexible bearings that can account for post misalignment and require zero O&M greasing for the entire life of the project.

All of our trackers utilize low voltage DC motors that are readily available. I have worked for a tracking company that uses hydraulic actuation instead, and I don’t miss having to search for pin-hole leaks on 100ft. long cables, praying that the leak isn’t occurring underground if I can’t find it the first pass. I also don’t miss maintaining pumps, changing the oil, replacing clogged pistons, lines that were never bled properly, or wildlife that somehow makes its way through the an 8ft. fence just to chew on the hydraulic lines. Our Single Axis tracker houses 4x more modules than the leading competitor. This means 4x less control boxes, sensors and motors that need to be maintained over the course of 25+ years. Additionally, our UL3703 certified Single Axis tracker can electrically bond over 320 modules within its structure so that you have 4x less grounding electrodes to worry about installing than with the leading 80-module tracker.

9 Interesting Facts about Solar Power

by Sun Action Trackers

The use of solar power for homes and business is on the rise, but how much do you know about it? While most people know that solar power energy comes from the sun, here are some fascinating and lesser known facts about it.

  1. Solar energy ranks number one when it comes to the biggest energy resource on the planet. The earth receives 173,000 terawatts of power from the sun on a regular basis, making it the most abundant source of energy in the world.
  2. Solar energy isn’t just used to generate electricity for homes and businesses. Photovoltaic cells, or solar cells, can also be used to produce power for portable devices, such as phone chargers and calculators.
  3. The space industry adopted the use of solar power back in the 1960s. This energy source was used to generate power on spacecrafts, including satellites.
  4. Ancient Greeks and Romans made use of solar energy to heat their homes and provide light by including windows that faced south. Other ancient civilizations also used the sun’s rays for heating.
  5. Solar panels have been around since the 1950s, but they weren’t used in homes or businessess back then. Now, solar panels provide energy for many homes and businesses around the world.
  6. Solar tracking systems utilize many forms of obtaining energy from the sun. A beneficial way is by using Real-Time Sensors, which help guide solar trackers to “track” the sun. They also help eliminate electricity loss by positioning the trackers in a “flat” position during a cloudy day.

7. Solar power can be used to provide homes and businesses with hot water, in addition to generating electricity. This helps property owners enjoy even greater utility savings while also lowering their carbon footprint.

8. Solar energy can be used to treat waste water, which cuts down on the use of chemicals or electricity for this same purpose.

9. Solar panels might look smooth from a distance, but they’re made up of tons of solar cells. These photovoltaic cells gather sunlight and convert it into electricity for homes and business owners to use for power, heat and other purposes.
