摘要：
Solar energy is the main source of all energy on earth.The earth obtain the total energy annually is ten thousand times of the earth energy consumption at present, but the solar energy has a lower energy density on the earth's surface. If-we want to Use the-solar energy, it is necessary to solve the intermittent and reliability problems of solar energy. The paper presents the principal of error analysis and deduces a formula of measurement error for heat coefficient in solar assisted heat pump system. We analyses the influence of water temperature, water flow and electrical energy consumption on measurement error of heat coefficient in the system. The result stresses that the key factor of reducing the measurement error is water temperature measurement of the system.
