-Due to their design, [[electrical:​solar:​charge_controller#​pwm|PWM]] and [[electrical:​solar:​charge_controller#​shunt|shunt]] charge controllers will very rarely allow the panel to run at max output for given conditions. ​ The lower the battery voltage (Vbatt) the lower the panel voltage (Vpanel), therefore the lower the power output.((Vpanel * ~Imp = P))+Due to their design, [[electrical:​solar:​charge_controller#​pwm|PWM]] and [[electrical:​solar:​charge_controller#​shunt|shunt]] charge controllers will very rarely allow the panel to run at max output for given conditions. ​ The lower the battery voltage (Vbatt) the lower the panel voltage (Vpanel), therefore the lower the power output.((Vpanel * ~Imp = P))  The output can be increased somewhat by [[electrical:​solar:​pwm_tweaking|tweaking battery voltages higher]].
  
 [[electrical:​solar:​charge_controller#​mppt|MPPT]] controllers can run the panel at max output when needed, but are much more expensive. ​ [[electrical:​solar:​charge_controller#​mppt|MPPT]] controllers can run the panel at max output when needed, but are much more expensive. ​

 **Optimum aiming** involves both tracking the suns elevation above the horizon (zenith) and tracking the sun's east-to-west travel (azimuth). ​ Doing both can increase yield ~30% but requires frequent repositioning. **Optimum aiming** involves both tracking the suns elevation above the horizon (zenith) and tracking the sun's east-to-west travel (azimuth). ​ Doing both can increase yield ~30% but requires frequent repositioning.
  
-**Leaving panel tilt in a reasonable default** is more common and has milder yield improvments. ​ In this approach the panel is aimed at true((not magnetic)) south((in the northern hemisphere)) at a particular angle above the horizon ​depending on time of year and latitude.+**Leaving panel tilt in a reasonable default** is more common and has milder yield improvments. ​ In this approach the panel is aimed at true((not magnetic)) south((in the northern hemisphere)) at a particular angle from perpendicular((ie,​ flat panel)) ​depending on time of year and latitude.
