Using this energy
calculator you may determine how much energy an Chino Solar collector will produce each day/month/year. The way
you utilize this energy is up to you. You can heat water
for showering and washing clothes, or central heat a building.
In fact one integrated system can complete both these functions.
You can also use these values to help you calculate how
much energy you can save by using an Chino Solar solar collector.
In order to calculate energy output you must input the following
variables:
Insolation Level - Before you calculate
your energy output, you must know your solar insolation level.
This are 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/m2/day. 1 kWh/m2/day
= 317.1 Btu/ft2/day
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 = 0.08m2 per tube.
Therefore an Chino Solar AP 20 tube = 1.6m2 absorber area
- 58/1500 = 0.067m2 per tube
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/m3 = 10.83 kWh/m3
LPG Propane (liquid) = 25.3MJ/L = 7kWh/L
LPG Propane (gas) = 93.3MJ/m3 = 25.9kWh/m3
