In Brooklyn Children's Museum effort to be green. The city has installed 2 sets of 48 solar panels. They are attached to the South and East side of the new building. There are 2 addition sets of panels on top of the building. Together you can see the graph above is an hourly total of the amount of energy the panels are giving back to the city. As you follow the KiloWatt per Hour trend it fluctuates as the weather changes. Clouds, angle of the sun, temperature are some of the factors that will change the output of our panels. Did i forget to mention dust and dirt on the panels will also have a large impact  so it is important to keep them clean.
