Performance Equations	.872 - 3.729 (Ti - TA) / I K_AX = 1.00 - .0316(S) - .0104(S)²		.825 - 3.74 (Ti-TA)/I K_AX=1.00-0.4(S)

Performance Note:
Solar Scientists agree that there are many variables to consider when properly sizing a system. Wind conditions, micro climates, flow rates, orientation and shading of the pool and/or collectors all effect the performance of your system. A BTU rating is just one of the many factors to consider.
