Abstract :Biogas is a good source of renewable energy. This research work has been done for the design, fabrication, and investigation of a digester with solar thermal flat plate collector to heat slurry inside the digester in order to maintain the temperature in appropriate range insert ignore into journalissuearticles values(37±2);. For production of continuous biogas in winter, a minimum temperature is required for the slurry 7kg COD/m 3 organic waste. The Hydraulic Retention time for this research experiment was 12 days. Flat plat thermal collector is used in this research to heat water and circulate it inside the digester. The hot water is circulated by copper coils during the winter season. By adopting this method the temperature of the slurry enhanced to required minimum temperature and the production of biogas was continued through the whole year in the colder area. The data collected from the experiment showed that using of flat plat thermal solar collector is the appropriate method for heating slurry to produce biogas through the whole year in the colder area in winter season.
