Dokument vsebuje tudi metodo za opredelitev toplotne učinkovitosti in predvidevanje sistemske učinkovitosti majhnih neserijsko izdelanih sistemov s pomočjo preskušanja sestavnih delov in simulacije sistema.
Poleg tega dokument vsebuje metode za opredelitev toplotne učinkovitosti in predvidevanje sistemske učinkovitosti velikih neserijsko izdelanih sistemov.
Ta dokument se uporablja za naslednje vrste majhnih neserijsko izdelanih sončnih ogrevalnih sistemov:
– sistemi, namenjeni izključno pripravi tople vode v gospodinjstvih;
– sistemi, namenjeni izključno segrevanju prostorov;
– sistemi, namenjeni pripravi tople vode v gospodinjstvih in segrevanju prostorov;
– drugi sistemi (npr. vključno s hlajenjem).
