Solar Panel<br />
The LEGO Solar panel provides sufficient power to<br />
operate LEGO mot<strong>or</strong>s. It delivers: 3V, 200mA in full<br />
sunlight outdo<strong>or</strong>s, 3V, 100mA indo<strong>or</strong>s with full sun outdo<strong>or</strong>s,<br />
2.5V, 8mA with light from a<br />
60W incandescent bulb<br />
positioned 25 cm from<br />
the solar panel (2000<br />
lux), and 2.5V, 40mA<br />
with light from a<br />
60W incandescent<br />
bulb positioned<br />
8 cm from the panel<br />
(10,000 lux).<br />

Technology<br />
Using a LEGO solar panel <strong>or</strong> a LEGO mot<strong>or</strong> as generat<strong>or</strong>,<br />
the capacit<strong>or</strong> can be charged and discharged just like a<br />
rechargeable battery. The capacit<strong>or</strong><br />
can be used f<strong>or</strong> powering a LEGO<br />
mot<strong>or</strong>. When the capacit<strong>or</strong> is fully<br />
charged, operating voltage is<br />
n<strong>or</strong>mally 2.5V. A red diode<br />
lights flashes when<br />
fully charged.<br />
The capacit<strong>or</strong> is<br />
protected against<br />
reverse polarity.<br />
