How many hours of sunlight does it take to capture the same amount of energy stored in 1 L of petrol, if instead of using a tree we use a solar panel?Assume: a tree takes up around 30 m2 of land area; we have a solar panel with the same area as that taken up by the tree; 1 L of petrol contains 34.2 MJ of energy; a solar panel captures energy at an average rate of 50 W/m2 for 12 hours a day. How many hours does it take to capture the required amount of energy? Give your answer to one significant figure.

How much energy does Hannah the Standard Poodle absorb from the sun during a 37-minute walk? Hannah’s fur is matte black, so she absorbs nearly all of the sunlight that hits her; from above, she looks approximately like a rectangle that is 92 cm long and 32 cm wide. The solar intensity in Hannah’s Orange County neighborhood is 1200 W/m2.
The Earth intercepts 1.27 × 1017 W of radiant power from the Sun. Suppose the Earth, of volume 1.08 × 1021 m3, was composed of liquid water.

How long does a 65 kg adult need to walk at a rate of 5 km/h in order to burn off all the energy in half slice of pizza. Each slice of pizza contains 1260 kJ of energy. The metabolic power for walking at 5 km/h is 380 W. O 27.6 min O 6.9 min O 55.3 min O 13.8 min
In this question we are going to compare the costs of generating electricity using solar energy in different parts of the United States. Let us consider a simple 20. m2 rooftop installation of crystalline-silicon (c-Si) PV modules. Remember that PV modules are rated to receive 1.0 kW/m2 of solar radiation. Assuming peak solar irradiance of 1.0 kW/m2 , what would the peak output of this system be (in kW) if the modules are 23% efficient?
The best solar panels currently available are about 19% efficient in converting sunlight to electricity. A typical home will use about 40. kWh of electricity per day (1 kWh=1 kilowatt hour; 1kW=1000J/s). Assuming 8.1 hours of useful sunlight per day, calculate the minimum solar panel surface area necessary to provide all of a typical home’s electricity. The energy rate supplied by the sun is 1.0kJ/s times meters squared . Area = meters squared
The total rate at which power is used by humans worldwideis approximately 15 TW (terawatts). The solar flux averagedover the sunlit half of Earth is 680 W>m2 (assumingno clouds). The area of Earth’s disc as seen from the Sun is1.28 * 1014 m2. The surface area of Earth is approximately197,000,000 square miles. How much of Earth’s surfacewould we need to cover with solar energy collectors to powerthe planet for use by all humans? Assume that the solar energycollectors can convert only 10% of the available sunlightinto useful power.
