Question

Chapter 5, Section 5.4, Question 012 Solar photovoltaic (PV) cells are the world's fastest growing energy source. In year t since 2007, PV cells were manufactured worldwide at a rate of S = 3.7e".Olt gigawatts per year. Estimate the total solar energy-generating capacity of the PV cells manufactured between 2007 and 2011. Round your answer to three decimal places. The total solar energy-generating capacity is gigawatts. 1www.earth-policy.org/indicators/Temp/solar_power_2011. Accessed February 2013. A gigawatt measures power, the rate of energy generation. In this case, we are considering gigawatts of capacity manufactured per year. the absolute tolerance is +/-0.001

Answer 1

Solution Given: Rate of manufacture of PV cells (S) = 3.7 e toob gigawatt/year 1 where t time in year science 2007 you have to estimate solas- energy generating capacity beswells 2007 to 2011. Solution: Solar energy generating capacity between 2007 to 2011 - area under date of manufacture of pv cells from 2007 to 2011 for 2007 do I for 2011 - 2011- 2007 - 4 1 4 S.dt ta 3.70 +0.6lt ( Take constand outside) 239 2406+ - 3.7 lnto.fit (Sek.de ekt) da eka
