I'm not sure if everyone knows the specs for the solar cell, so here are the
specs straight from the Dacta web site:


> The LEGO Solar Cell
> eLAB - LEGO Sets for Schools

> The LEGO Solar Cell is included in the 9681 - Renewable Energy Set;
> it may also be purchased separately (article number 9912).

> The solar cell consists of seven (7) solar cells and a diode.  They are
> connected in serial so the total volt  = 7 x 0.4 volts (a total of
> approximately 2.8 volts).


> Specifications:

> 3 V, 200 mA at full sun outdoors
> 3 V, 100 mA at full sun indoors through window
> 2.5 V, 8 mA with light from 60 w incandescent lamp with 25 cm >distance to • solar cell (2000 lux)
> 2.5 V, 40 mA with light from 60 w incandescent lamp with 8 cm >distance to
solar cell (10,000 lux)


> Cautions:

> Do not bend excessively or push hard on the clear plastic window
> Do not step on or or otherwise place heavy weight on the solar cell
> The solar cell is not waterproof
> Ordinary incandescent lamps produce a lot of heat and should only be
> used for short periods and at a distance of at least 8 cm.

(...) So, at three volts, a typical LEGO motor will run maximum at 1/3 power. It would take linking three of these LEGO panels to bring one up to 9 volts. Other panels, such as sold by Edmund Scientific, are 9 - 12 volt in just one panel. Alan C (27 years ago, 11-Jul-99, to lugnet.robotics)
