greenhouse gas production by using electricity from sunlight.\u00a0 But many things can affect the amount of electricity from solar cells.\u00a0 Here are some things that will do that: trees, houses, clouds, time of year, and where you live in the world.<\/p>\n<p><a href=\"http:\/\/mightyelephant.com\/ams\/wp-content\/uploads\/2009\/03\/img_3775_medium.jpg\"><img loading=\"lazy\"

Sometimes, clouds would cast a shadow on the array so we would have to wait for the cloud to pass. And the sun moved so I would have to reposition the array often.<\/p>\n<figure id=\"attachment_203\" aria-describedby=\"caption-attachment-203\" style=\"width: 150px\" class=\"wp-caption

of electricity coming into the solar cells goes down and it looks like when the angle is about 90 degrees, meaning that the solar cell array is perpendicular to the sun, it gets the most light and gets the most volts.<\/p>\n<h3>References:<\/h3>\n<p><a href=\"http:\/\/www.engineeringinteract.org\/resources\/siliconspies\/flash\/concepts\/simplecircuits.htm\"
