estimate the area of land that must be found to construct this facility.
You are serving as an expert witness for the city council of a community. The council is exploring the concept of providing the electrical needs of the community by building a facility with photovoltaic cells to convert sunlight to electric potential energy. But they are facing resistance from members of the community, who claim that there is not enough open land in the community to build such a facility. The opposition is building toward a lawsuit, which the city council wants to avoid. The community requires 1.00 MW of power, and the best photovoltaic cells on the market at the time have an efficiency of 30.0%. In your community, an average intensity of sunlight during the day is 1 000 W/m2. The council members have no idea how much land is needed, so they have asked you to estimate the area of land that must be found to construct this facility.
