The table shows that the ocean's primary heat loss mechanism is also radiation, at ~ 401 W / m ^ 2. (realclimate.org)

In theory, silicon - based solar cells are capable of converting up to 30 percent of sunlight to electricity — although, in reality, the different kinds of loss mechanisms ensure that even under ideal lab conditions it does not exceed 25 %. (sciencedaily.com)
