What is the use of a photocell in a thermic fluid heater??

How do I turn a relay on with the output of photo cell sensor? Please help me?

You will need a photocell amplifier circuit of some type in order to drive the coil of the relay. The photocell may not drive the coil directly because most of them only have a range of resistance that they will swing from off to on. if you have a specific photocell already, you may be able to look up specs at websites like "datasheet 4U" or "datasheetcatalog.com" and many times they will have test circuits you can build your self, ok?

Does this cost me money having lights on all night long every night?? Trying to reduce my power bill.

No it uses sunlight to create electricity that powers the light on.
