 | | Solar Cell Output in Direct Sunlight —Micah J. Mabelitini
|
| | | Well, it finally got sunny here. In direct sunlight, the solar cell seems to put out about 4V, 135mA (24 years ago, 23-Mar-01, to lugnet.robotics, lugnet.dacta)

The solar radiation angle is still fairly low at this time of year with much of the energy being scattered by the atmosphere as well as being spread over a larger surface area of the earth. I (...)

Well, I could certainly create an artificial environment which would increase the solar cell's output without the need for scheduling another test on the summer solstice, if you were merely curious as to its maximum output based on the cell's (...)

The amount of light varies as the cosine of the angle of the sun to a line thats perpendicular to the panel. Building some kind of a mechanism that tilts the panel (...)

If it's something that only goes in straight lines then in can adjust the panel one time - and then only have to make (...) (24 years ago, 27-Mar-01, to lugnet.robotics)

| | | | | | I have a Halogen uplight lighting a room and my solar cell will power a motor, with no load up to a distance of around '6 (3' work height) from the light pole. This will fluctuate according to the reflectance's of the ceiling, walls, etc. Rose (...) (24 years ago, 6-Apr-01, to lugnet.robotics, lugnet.dacta)

They are a nice curiosity, but as of right now, I can't seem to find any robot applications. Maybe when the sun comes back to Toronto, (...) (24 years ago, 1-Apr-01, to lugnet.robotics)
