At a certain location, the solar power per unit area reaching the Earth's surface is 210 W/m2 averaged over a 24-hour day. Suppose you live in a solar powered house whose average power requirement is 3.2 kW. At what rate must solar energy reach your solar panels if your solar panels have a typical coversion efficiency of 13 %. (In other words, what power must your solar panels receive?) Answer in both kiloWatts and Watts. Psolar = Psolar = Based...

Professor has 14 photovoltaic panels on his roof, and the effective PV area OF EACH PANEL is 3ft x 5ft. At 12:20PM on October 12th, these panels were generating 2 kw of power. At that same time, the solar radiation measured by the weather station showed that the incoming solar radiation was 415 watts/m2 . 1. Determine the instantaneous efficiency of the system at this point. Note that you need to convert from square feet to square meters, and from...

3. Dominion Virginia Power, the state’s primary utility, now has a Solar Purchase Program that allows residents to sell solar-generated electricity back to the grid at a premium rate. Suppose a farmer installs solar panels on their property that generate 900 kWh of electricity per month. The farmer only consumes 600 kWh per month, which they would otherwise need to purchase from the utility at $0.11 per kWh, so the excess energy can be sold back to the grid at...

An experimental power plant at the Natural Energy Laboratory of Hawaii generates electricity from the temperature gradient of the ocean. The surface and deep-water temperatures are 30 ∘C and 5 ∘C, respectively What is the maximum theoretical efficiency of this power plant? If the power plant is to produce a power of 180 kW , at what rate must heat be extracted from the warm water? Assume the maximum theoretical efficiency (in watts). At what rate must heat be absorbed...

You need to use your metabolic rate in watts as calculate early( MR, or heat energy production and transfer). You are on holiday in a tropical paradise. On a typical day your rectal temperature is 37c and your mean skin temperature is 33c. Suddenly a malaria attack developed with a 7 day folds rise in MR, and you reach temperature plate of 40c with a mean skin temperature of 34c. The conductance if shell is measured if skin blood flows....
