What would have to be the area of a horizontal solar collector in Boulder on Dec 21 (Table 4.2) to provide 1000 Watts for the 24 hour day? Assume some lossless battery system, and a conversion efficiency from sunlight to electricity of 25%.
Table 4.2 says the Horizontal solar collector on Dec 21 insolates 782 Btu/ft^2 per day

What collector area is needed for the system shown in Figure 4.6 to provide the necessary space heating for a home having 2000 ft^2 of floor area? Assume an average daily insolation of 1000 Btu/ft^2 and an efficiency of 50%. Also assume that the house requires 50 million Btu per thousand square feet of floor area for the 180-day heating season.
