How much energy an AP 30 solar collector will produce each day/month/year?

 

Insolation Level - Before you calculate your energy output, you must know your solar insolation level. This is available from the insolation page. Take note of your max and min levels throughout the year as well as the annual average value. When assessing potential energy savings, input annual average insolation, and take note of the "per year" energy output value.
Energy must be input in the unit kWh/m
2/day >>> 1 kWh/m2/day = 317.1 Btu/ft2/day

 

What is solar insolation?
Amount of electromagnetic energy (solar radiation) incident on the surface of the earth. Basically how much sunlight is shining down on us.

Collector Size - You must enter the collector size in absorber surface area.
The absorber surface area of the various tubes sizes are as follows:
- 58/1800 = 0.08m
2 per tube. Therefore an Apricus AP 30 tube = 2.4m2 absorber area
- 58/1500 = 0.067m
2 per tube

So I assume we will use AP 30 but I am not sure this is right because I couldnt remember. I should check. But this is assumption.

 

Energy Cost - Enter cost per kWh in your local currency (may need to convert from m3 or Therms)
1 therm = 29.3kWh = 100,000Btu = 105.5MJ
Natural Gas is 39MJ/m
3 = 10.83 kWh/m3
LPG Propane (liquid) = 25.3MJ/L = 7kWh/L
LPG Propane (gas) = 93.3MJ/m
3 = 25.9kWh/m3

Insolation Level =

 kWh/m2/day

Absorber Area =
