  Tiivistelmä. Tämän työn tarkoituksena oli koota yksinkertainen aurinkosähköjärjestelmä, mitata järjestelmän tuottaman sähköenergian määrä ja verrata tuotetun energian määrää BCDC Energian kehittämän Energiasääennusteen ennustamaan tuotantomäärään. Tarkoituksena oli selvittää ennusteen tarkkuutta ja luotettavuutta. Luotettavalla lyhyen aikavälin energiantuotantoennusteella olisi käyttöä sekä pienten ”mökkijärjestelmien” että suurten aurinkovoimaloiden energiantuotannon ennustamisessa. Työssä käytettiin yksinkertaista aurinkosähköjärjestelmää, joka koostui aurinkopaneelista, akusta, lataussäätimestä ja näyttölaitteesta sekä kuormana käytetystä ledinauhasta. Tällaista järjestelmää kutsutaan yleisimmin off-grid-järjestelmäksi tai mökkijärjestelmäksi. Järjestelmällä suoritettiin mittauksia keväällä ja kesällä 2022 erilaisin asennuksin. Järjestelmän pienuuden takia tuotetun energian määrä jäi ennusteeseen nähden hyvin pieneksi, mutta skaalauksen avulla vertailua pystyttiin tekemään.Testing of a photovoltaic system. Abstract. The purpose of this thesis was to assemble a simple photovoltaic system, measure the electrical energy produced by the system and compare the amount of produced energy with the predicted amount that is generated by Energy weather forecast, which is produced by BCDC Energy. The idea was to evaluate the accuracy and reliability of the forecast. A reliable short-term energy production forecast would be useful for predicting the energy production of both small off-grid systems and big solar power plants. A simple photovoltaic system was used in the thesis. The system consisted of a solar panel, a battery, a charge controller, a remote meter, and a led strip, which was used as a load. This kind of a system is usually called as an off-grid system. Measurements with the system were conducted in the spring and summer of 2022 with different installations. Due to small size of the system, the amount of produced energy was tiny relative to the amount forecast. B
