                     Calculations to determine the equipment that is needed:
Solar:
1. Sun hours per day:                                                   
2. Solar panel watts needed (divide your total electricity need by the number of sun hours):  
3. Watts provided by cabin kit  
4. Watts still needed (Line 2 - Line 3)  
5. Number of additional panels to buy (divide Line 4 by the rating of the panels; round up!)  

Wind:
1. Wind class                                                   
2. kW-hrs/day needed (divide your electricity need by 1000)  
3. kW-hrs per day expected from XL.1 turbine  
4. Number of turbines needed (divide Line 2 by Line 3; round up!)
