 [[electrical:solar:charge_controller#mppt|MPPT]] controllers can run the panel at max output when needed, but are much more expensive.
+===== wiring losses =====
+Long runs of wire between the panel and controller can result in losses that make the panel //appear// to be putting out less power.   In reality, the lost power has been converted to heat((from resistance)) in the wiring.  Solutions:
+  * use shorter runs
+  * use thicker wire
+  * prefer [[electrical:solar:panels#panel_voltage|higher voltage panels]]
+  * if multiple panels, run them in serial instead of parallel to decrease carried current
 ===== panel temperature =====
