    I just finished soldering a string of 9 solar cells together. When I checked them with a...

    multimeter it is only reading .5v rather than 8v. Did I use too much heat and can I somehow fix it?

    I don't know about solar cells per se, but here are some things to consider.  Is there a polarity requirement?  If so, are they connected properly?  Is one or more bad (damaged)?  Can you determine that by checking the voltage of each cell individually, not just the output of the whole array?

    What voltage are the cells you are using?

    0.5V is typically what 1 solar cell should read when in light.

    Odds are you solder job isn't that great and isn't making a good connection.

    Reflow the solder and recheck.

    You also want to make sure that you have it exposed to proper light.

    my guess is that you wired them together into a serries instead of a parallel circut... if you did then your reading would be only .5v  like MikeMitchell said thats the typical out put of a cingle solar cell. When you wire in serries you increase the ampperage of the unit but maintain the same voltage. when you wire in parallel you increase the voltage and not the ampperage of the circut. I would google both parallel and serries circuts to see which one you did then try the project again. Yes heat could be a factor but I doubt that you would see a decrease in cmbined voltage rather the circut would fail compleetly.
    Hope this helps
