The intensity of sunlight on earth is about 100 mW/cm (that's milli-Watts per cm squared). If you had a 100% efficient solar panel that was 1m?, could you use it to light a 100W lightbulb? What if it was only 20% efficient (a bit more realistic..)? What's the total power output of the sun? The distance from the sun to earth is about 150 x 10° km.

In Washington, a solar panel facing south angled at 15 degrees receives 0.5 (+/- 0.5) kWh/m^2/day in the winter. Solar panels are 20% efficient. Another 20% of power is lost due to heat. A house uses 45 kW per day in the winter. What is the minimum number of panels needed?
The image attached is a neat copy of a photo of an electricity meter for a domestic solar array. The display shows the energy we sold to the electricity company on a winter's day. Each box is 100 W high and 1 hr wide. At the radius of the earth's orbit, the intensity of sunlight is I=1.4 kW.m–2 . (This means that 1.4 kW.m–2 passes through 1 square metre at right angles to the sun's rays.) The solar array in the previous question consists of 10 panels, each with area A=1.6 m2 . Under optimal conditions - with the sun at right angles to the array and no clouds in the sky - the array produces Pout=2.3 kW . What is the efficiency of the array? Power out/power in = _____ %.
The energy flux from the sun has a peak value of around 1500 W/m2, and solar cells are around 15% efficient. Estimate the area needed to satisfy US energy needs using solar cells, using the estimates that there are about 350 million people in the US and that we use an average of 90 kW/person. Also assume that there are about 6 hours of "peak" sunlight per day. Answer in square kilometers (do not put units in your answer, however).
What area is needed for a solar collector to absorb 45.0 kW of power from the Sun's radiation if the collector is 75.0% efficient? (At the surface of Earth, sunlight has an average intensity of 1.00 × 10³ W/m².)
In a sunnier location than Eugene, the sun shines for an average of 2000 hours per year. A home owner installs solar panels that generate 3.5 kW from these panels when the sun is shining. If the local electric utility charges $0.15 per kWh, how much money do the solar panels save the home owner per year? Give the answer to the nearest dollar.
