The city of Los Angeles released 96 million "shade balls" into the Los Angeles Reservoir. These will serve to shield the water from the sun's heat in order to reduce evaporation and prevent algal and bacterial growth so no toxic substances are produced in the water. The balls reduce evaporation by 85%-90% so will save a lot of water yearly.

Let's say that the cost of the solar panel installation is 12,500 and the Reyes family pays 200 a month for electricity. in 40 years the Reyes family would have saved a lot of money on electricity.
f(480)=200(480) - 12,500 
the Reyes family would save 
83,500$ in 40 years.
