A module is a 46” x 46” (117cm x 117cm) enclosure
composed of 3 Pyropeg’s solar heat exchangers, glass covered and
insulated. A module insolation surface is 13.5 Ft²(1.25m²); these
modules are designed to be mounted in tracks as part of a large array.
| A module (1.25m²) captures an average of 9,400 BTUs | 9,400 BTU daily |
| 400 modules | 3,760,000 BTU daily |
| There are about 20 sunny days per month (In the Caribbean area) |
75,000,000 BTU monthly |
| A oil fired boiler yields an average of 150,000 BTU per Gallon of fuel | |
| A conventional boiler will burn approximately | 500 Gallon/ Oil |
| Of oil to produce an equivalent amount of | 75,000,000 BTU |
The cost of oil has increased dramatically since 1996.
It is safe to say that the biggest advantage of solar energy is its permanency.
The price increase of solar energy is limited to the increase in the cost associated with its maintenance and the depreciation of its initial cost. As a consequence each increase in the price of oil results in a relative decrease in the initial investment in solar energy.
