Let's see if I can answer this:

1. Materials used in manufacture are in some instances toxic, causing disposal problems.

2. Creation of a solar pain requires a fair amount of "energy". It may take a long while for the solar collector to "repay" that initial energy expenditure.

3. Solar panels don't work at night. Also, solar panels don't work well on cloudy days.

4. Solar panels are somewhat delicate, so repair costs need to be factored into the equation.

5. Solar panels work best at low latitudes and are increasingly less effective at higher latitudes.
