Heating supply system using solar energy-collecting plate was examined for 20 farmers. Some problems, resolution, future energy system, and basic information were discussed, Installation cost was approximately 18 million won/20a. Main crops cultured were tomato(30%) and floricultural crop(40%). Minor crops cultured were grape, red pepper, cucumber, lettuce, and strawberry. Information was mostly obtained from agricultural service agents. 75% of farm house hold reported that energy reduction effect was below 20%, showing some different result compared with over 20% that was totalized from agricultural service agents. Cost of installation was excessive in considering energy reduction effect. Another problem was insufficient technical proficiency of solar energy company.
