I would like to put a transistor (PN100?) in place of the RProg resistor to regulate the current, with the base somehow connecting to the output of the solar panel. This way, if the voltage from the solar panel started dropping off (say below 10 volts) due to excessive demand by the charger, the transistor could ease off the charging current. If the sunlight strengthened, The transistor would up the charge current to make the most of the solar panel potential.
