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 (25 years ago, 11-Jul-99, to lugnet.robotics)
