How much is one hour of sunlight on three square meter worth? Let's see, if we're talking about electricity and we say that electricity is worth $0.10 per KWH than 3KWH's are worth $0.30. The problem is that PV panels have a radiant energy conversion rate of about 20% or less so three hours of sunlight on one square meter of a solar panel is worth less than $0.06

How about heat? How much is 3 hours of sunlight on one square meter of a solar collector worth if we're talking about heat? Well 1KWH = 3400 BTU so 3KWH = 10,200 BTU. Since one gallon of fuel oil contains 150,000 BTU 10,200 BTU's are the equivalent of .07 gallons of fuel oil.
