We have an electronics enclosure that has a top with 23.3 square feet. It is painted white and I have read that a glossy white paint will absorb only 14 percent of the solar heat. That tells me that of the the 97 watts per square foot from solar radiation this top will will absorb 13.58 watts for a total of 316.414 watts. I understand that 316.414 watts is converted to btu via the constant 3.413 resulting in 1079.9 btu per hour.(adsbygoogle = window.adsbygoogle || []).push({});

The top has an R value of 9. How many watts of this solar radiation will get though the top? In other words, how much load will the solar energy put on my air conditioner?

Thank you,

B Kelly
