Are there any disadvantages to using solar energy?

Solar thermal systems most probably have higher "first costs" than other kinds of heating systems. Also, the energy is not available 24 hours a day and not sufficiently during all seasons of the year. That means that storage systems like water tanks and backup systems are a must in all solar thermal installations.
