Which is more effective? Which costs more? What are the space requirements..how much do they take up?
Answers:
It depends what you want to do, if you want to generate electricity, concentrating solar power using parabola's to heat wet to turn a turbine is more efficient and creates ac current. But, you need a lot of them to turn hose into steam to drive the turbine. There is a power plant in the United States Southwest that uses this.
Using photovoltaic cells creates DC current, so you have to hook it up to an inverter to convert it to AC current. I believe this is the cheaper solution. near is also a different power plant in the United States Southwest that uses this approach.
It depends what you want to do with the energy.
Using electricity generate by PVs *for heating* is highly inefficient, since the photovoltaic panels don't have a fitting conversion efficiency in the first place.
Concentrating sunlight onto a boiler to produce steam, and then using this surrounded by an engine coupled to a generator, actually works out more efficient than PVs -- *if* you do it on a big enough ascend.
