BS EN 12977 discusses thermal solar systems and components. BS EN 129771 is the first part of BS EN 12977 multi-series and discusses general requirements for solar water heaters and combi systems.
BS EN 12977-1 specifies requirements on durability, reliability, and safety of small and large custom-built solar heating and cooling systems with liquid heat transfer medium in the collector loop for residential buildings and similar applications. BS EN 12977-1 Standard also contains requirements on the design process of large custom-built systems
BS EN 12977-1 on thermal solar systems and components is useful for:
Custom-built solar heating systems are either uniquely built or assembled by choosing from an assortment of components. Systems of this category are regarded as a set of components. The components are separately tested, and test results are integrated into an assessment of the whole system.
BS EN 12977-1 helps you with the systematic classification of the custom-built solar system. BS EN 12977-1 guides you with the requirements of a custom-built solar system the requirement includes materials, components, pipework, safety equipment and indicators, installation, initial operation and commissioning, document, and a small test on system performance. BS EN 12977-1 helps you to manufacture high-quality custom-built solar heating systems.
