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
On average, would Earth be warmer or cooler without the atmosphere? Explain your answer.
The Earth constantly receives radiant energy from the sun and gets warmed up. Why does the Earth not get as hot as the Sun is?

- The sun doesn’t shine as brightly in winter as it does in summer. This means that in winter you won’t generate enough to fulfil your energy needs whilst you have a surplus of energy in summer. It is therefore necessary to place a battery in your house to store the extra energy. If we assume that we generate 66% of our total energy in the months April to September and that we use equal amounts of energy throughout the year. How much electricity must we store over these 6 months to use in the other half of the year? Give your answer in 3 significant figures. Remember we use 2990kWh of electricity per year.arrow_forwardHow 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.arrow_forwardThe sun doesn't shine as brightly in winter as it does in summer.
