Both of these types of panels can be employed for home use, but which one to choose should be based on your expectations and location. Solar Thermal Collectors are generally less expensive and a larger area can be covered with these cells. This type of panel really depends on the heat of the sun and does not do very well in situations where there is a lot of diffused light. These types of panels are best for larger homes in southern areas of the country, mainly where there is large open land or roof space to place the panels. Often times these panels will need dual-axis sun-tracking mechanisms, and that may require a little extra space. This would suit ranches and farms perfectly, both private and commercial, because of the open space that would be available.
