    IS SUN THE ANSWER?
    or is it both, the wind and the sun?

         
    Calculate the value of a sunny day.
    SOLAR PANEL CALCULATOR: CALCULATE YOUR POTENTIAL SOLAR POWER OUTPUT. Then compare it to wind as measured by an anemometer: Barani.biz -the value of wind
     
     
    AVERAGE YEARLY SUN INTENSITY
    kiloWatts per meter squared per hour (kW/m2/day)=
    (kWh/m2/day) = W/m2

    Solar Radiation Fundamentals = http://www.physicalgeography.net/fundamentals/6i.html  
       
    SOLAR PANEL EFFICIENCY % = % = W/m2  
    SOLAR PANEL AREA (m2) = m2 ft2  
    SOLAR RADIATON CAPTURED (kW/m2/hr)= (kWh/day) = W  
       
    HOW MANY LIGHT BULBS CAN I LIGHT UP? =  
    Light bulb Watt Rating (W) = Watts  
    Lights are turned on for how many hours per day? = hrs per day  
       
    Electricity cost per kiloWatt Hour (kWh) = cents  
    Reduction is Electric bill = Dollars/Euros (Savings per year)    
       
    Cost of solar panel installation = Dollars/Euros  
    Time for investment to pay back for itself = Years (return on investment)
