[TRNSYS-users] Inaccurate result for the energy gained by the fluid in the collector

[David BRADLEY]

Ayoola,
   Remember to account for the amount of energy that has been stored in 
or removed from the tank since the beginning of the simulation. If that 
does not solve your problem then I would recommend sending your project 
and your question to your distributor's technical support for assistance.
Kind regards,
  David
