 Understand that **efficiency is a relationship between rated output and physical panel size**:  a high-efficiency 100w panel will not make more power than a low-efficiency 100w panel.  It //will// be smaller.   Understand that **efficiency is a relationship between rated output and physical panel size**:  a high-efficiency 100w panel will not make more power than a low-efficiency 100w panel.  It //will// be smaller.  
 This means **if you have limited space you will get more power out of of the same space using higher-efficiency panels**.  That's it.  A 100w panel is a 100w panel, no matter how efficient.  Only the real estate needed to generate that 100w is different. Efficiency doesn't mean you'll get more or less power from a 100w panel.  So don't spend the extra $$$ on high-efficiency panels unless you need it to get max power out of limited roofspace. This means **if you have limited space you will get more power out of of the same space using higher-efficiency panels**.  That's it.  A 100w panel is a 100w panel, no matter how efficient.  Only the real estate needed to generate that 100w is different.

 +Mismatched panels (different voltage or current [[opinion:frater_secessus:electrical:solar:panels#specifications|spec]]) on the same controller will hamstring one another.  It's [[https://en.wikipedia.org/wiki/Glossary_of_tennis_terms#unforced_error|an unforced error]] which you can avoid this by:
 +
 +  * running //identical//((not //close//, not //same maker//, not //same wattage//, not //kinda  look the same)) panels on the same controller; or
 +  * run different-spec panels on their own controller
 +
 +If you are committed to running mismatched panels on the same controller see [[https://www.youtube.com/results?search_query=alt-e+mismatched|this series of videos by Alt-E]] on the subject.
