About Heat Flux Density

Heat flux density is the rate at which heat crosses a surface, in watts per square metre. Full sunlight at ground level is roughly 1,000 W/m², the figure solar panels are rated against. Building heat loss and heat-exchanger sizing both work in this unit. One W/m² is 0.317 BTU per hour per square foot.
