This is a fairly minimalistic 2-axis control setup.  You'll need the sensors to be in Mode 1 (horizontal) and Mode 2 (vertical), both facing up. The cable can point in any direction, as the vertical sensor doesn't care and we're already compensating for the horizontal sensor.
  
βˆ’
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.
+
To set the sensors, 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 first sensor's Mode variable. Then set the Writer to write to the second Sensor, and set the memory to 2 (in that order!). The sensors should say "Mode Horizontal" and "Mode Vertical". Once you have them set, 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.
βˆ’
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
 
βˆ’
to simplify the setup by removing an extra math, and memory chip(6 chips instead of 8).

==Solar tracking using Logic Chips ==
+
* Logic A (reader) reads SolarAngle from daylight sensor in Horizontal mode.
 +
* Logic B (math unit) subtracts Logic A from Logic C.  Note that it must be upside down!
 +
* Logic C (memory) should be one of 90, 180, 270 or 360.  We're using it to compensate for horizontal sensor orientation.  If the sensor cable points the same direction as the solar panels power port, set it to 90.  Add 90 for every rotation counterclockwise.
 +
* Logic D (batch writer) reads from Logic B, and writes to Horizontal field for all Solar Panels.
 +
* Logic E (reader) reads SolarAngle from the sensor in Vertical mode.
 +
* Logic F (math unit) divides Logic E by Logic G.
 +
* Logic G (memory) is set to 1.5.  It's used to scale from 180Β° that the sensor reports to the 100% that the solar panels use.
 +
* Logic H (math unit) subtracts Logic F from Logic I.  Note that the ''right'' input must be Logic F, and the ''left'' input must be Logic I!
 +
* Logic I (memory) is set to 50.  The vertical reader reports 0Β° at midday and 90Β° at sunrise/sunset, but we need the panels to be at 50% at midday and 0% at sunrise/sunset.
 +
* Logic J (batch writer) reads from Logic H and writes to Vertical field for all Solar Panels.

2 sensors setup as shown above<br>
 +
2 memory<br>
 +
2 Batch Writers that read from memory<br>
 +
<br>
 +
Connect '''Sensor1''' to '''d0''', '''Sensor2''' to '''d1''', '''Memory1''' to '''d2''', '''Memory2''' to '''d3'''.
 +
BatchWriter Horizontal should read from '''Memory1''' and BatchWriter Vertical should read from '''Memory2''' and both ofcourse write to the solar panels.
 +
Use the same setup for the power connector directions as shown above. You do not have to write the mode, this is done in code.

== Accurate Solar Setup ==
 +
'''Authors:''' Wooodiii, Corvus_bkgk, Enfantcool, Baksch<br>
 +
'''Properties:''' Accurate (average error 1.3Β°), Auto-reset (variant), Power conserving (variant)<br>
 +
'''Number of Components:''' 10-12
 +
<br>'''Math Formula:''' <code>f(x) = min((x-min(x,15))/1.5, 100)</code> where '''x''' is the solar angle.
 +
 
 +
'''Note: With the introduction of ecliptic solar angles, this setup no longer works at peak efficiency on worlds such as Mars and Europa which have the sun at an angle. This setup will still work on the Moon and in Space.'''
 +
 
 +
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.
 +
 
 +
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 15Β° short). The listed average error is nonzero only because of this completely unavoidable portion; the error is 0 throughout the 15Β°-165Β° portion of the day.
 +
 
 +
This setup produces the equivalent of 274W averaged over a whole day/night cycle.

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.

'''Note: With the introduction of ecliptic solar angles, this setup no longer works at peak efficiency on worlds such as Mars and Europa which have the sun at an angle. This setup will still work on the Moon and in Space.'''

This is the most powerful way to track the sun, but the implementation might be a bit daunting at first.
 
  
βˆ’
'''What you need:'''
+
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.

* IC Editor Motherboard
 
  
βˆ’
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.

=== Notes ===
βˆ’
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
+
* The [[Daylight Sensor]] MUST be facing East (Sunrise), but its rotation doesn't matter.
 +
* Solar panels should be rotated such as that 0% VERTICAL rotation faces East/Sunrise, and 100% VERTICAL faces West/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 6.5Β° and increases overall power generation, particularly in the afternoon.
