While this specific Guide calls out the sensor being place a specific direction(north), its not necessary to orient your sensors to a specific direction.

If you find your panels don't point at the sun, you can add either 0,90,180 or 270 to the horizontal until they point at the sun. This guide is an attempt

to simplify the setup by removing an extra math, and memory chip(6 chips instead of 8).

This setup is accurate, giving 495-500W throughout the day, with lower output only when the sun is lower than the panels can physically aim at.

==Solar tracking using Logic Chips ==
+
This setup adjusts for the fact that solar panels rotate through only 150 degrees. Instead of converting using 180/100, this setup converts by doing 150/100. It then clips the value at the edges, where the prior calculation would give elevations that are negative or greater than 100 (representing the fact that we would prefer the panel to track past 0 or 100, aiming all the way down to the horizon instead of stopping 15° short). The listed average error is nonzero only because of this completely unavoidable portion; the error is 0 throughout the 15°-165° portion of the day.

To get a "100%" accurate solar tracker on planets with an offset solar arc, you need to include the Horizontal component to the solar angle.

=== Power-Conserving Variant ===
 +
To conserve power, it's possible to avoid running the entire circuit at night. A transformer can be controlled to power the main logic network above. In this way, only the two new components need to remain powered at all times.
  
−
The panels should align themselves to the sun if you make sure to put the Power Port on the panels facing east (90 degrees). If you've already built the panels and logic with the Power Port facing west, swapping the direction of the sensor so that its Data Port faces south will allow the setup to work with no additional changes.

This imperfect setup is a common starting point. It starts off at 375w of power in the morning, builds up to 500w at zenith (noon) then back to 375. This is due to the fact that solars rotate through only 150 degrees of elevation and that this setup's math is correct only if they rotated through all 180 degrees of solar angle.

Place the Daylight Sensor facing up, note which direction the Data Port is facing, and which direction the solar panel Power Port is facing. These two directions are needed in the code. The Daylight Sensor is connected to the d0 screw, that's all you need.

This setup produces the equivalent of 239W averaged over a whole day/night cycle.

It targets the solar-panel types on d2 and (optionally) d3, so it's less spammy. It also has an option for a display (Kit (Console)) on d1 that shows the sum of power output from both types of panels

 +
=== Notes ===
 +
* The [[Daylight Sensor]] MUST be facing West (sunrise), but its rotation doesn't matter.
 +
* Solar panels should be rotated such as that 0% VERTICAL rotation faces west/sunrise, and 100% VERTICAL faces east/sunset.  
 +
* The [[Area Power Control]] is necessary for the circuit to stay powered during the night. It also hides all the modules from the rest of your system.
 +
* Importantly, the solar input power doesn't directly connect to any of the logic writers. This not only ensures your system doesn't lose power but also prevents short-circuiting that would burn cables.
 +
* Using 1.7 instead of 1.8 reduces the average error of this design to 6.5° and increases overall power generation, particularly in the afternoon.

This setup takes advantage of the new Horizontal Mode of the [[Kit (Sensor)|Daylight Sensor]], and as such, is a very compact setup. It provides 99% efficiency during the day, only dropping below when the sun is beyond the solar panel's vertical range (less than 15 degrees above the horizon).
 +
 
 +
To set the second sensor into Horizontal mode, you will need to use a [[Kit (Logic I/O)|Logic Writer]] and a [[Kit (Logic Memory)|Logic Memory]]. Set the Memory to 1, and set the Writer to write to the Daylight Sensor's Mode variable. Once the mode is written to the sensor, you can deconstruct and re-use the I/O and Memory units. They do not need to be left in place to keep the mode set.

=== Notes ===

* Sensor 1: MUST be facing upwards, Mode 0 (Default)

* Sensor 2:  MUST be facing up-side-down, rotated so the power input is facing north, Mode 1 (Horizontal)

* '''Don't forget to write the mode to Sensor 2''' ''once written it will remember it''

* Solar panels power should be facing facing west/sunset.
