Abstract Split-cell and multi-panel photovoltaic backtracking control systems and methods allow for increased total power generation during low sun elevation conditions by shading a percentage of panel modules, thereby allowing for a lower angle of incidence on unshaded modules. The control systems and methods involve determining a sun elevation angle, a traditional backtracking angle, a split-cell or multi-panel backtracking angle, a single-cell or single-panel relative light transmission (RLT) based on the single-cell or single-panel backtracking angle, and a split-cell or multi-panel RLT based on the split-cell or multi-panel backtracking angle. If twice the single-cell or single-panel RLT is greater than the split-cell or multi-panel RLT, the split-cell or multi-panel backtracking angle is used; otherwise, the single-cell or single-panel backtracking angle is used. The control systems and methods may further involve determining a diffuse fraction index (DFI) and, if the DFI is greater than a DFI limit, using a DFI tracking angle an b s t r a c t p l i t - c e l l a n d m u l t i - p a n e l p h o t o v o l t a i c b a c k t r a c k i n g c o n t r o l s y s t e m s a n d m e t h o d s a l l o w f o r i n c r e a s e d t o t a l p o w e r g e n e r a t i o n d u r i n g l o w s u n e l e v a t i o n c o n d i t i o n s b y s h a d i n g a p e r c e n t a g e o f a n p a n e l m o d u l e s , t h e r e b y a l l o w i n g f o r a l o w e r a n g l e o f i n c i d e n c e o
