Does anyone have any recommendations on the appropriate
solar cell technology for in flight recharging of sealed
lead acid batteries? Ie Eg what's the recommended
regulator technology - is it normal to shunt the solar
cells when the battery voltage rises at full charge
to prevent overcharging? This seems a little strange
to me (ie you allow the solar cells to discharge at
high current through a shunt thereby dissapating the
full wattage of the solar cells rather than increasing
the series impedance in the charging line).

Any recommended manufacturers
of regulator/shunt units? Any recomended panel suppliers?
