Customer ServiceIEC 61215 is the industry standard that defines the design and qualification of silicon PV modules for long-term operation in open-air, terrestrial applications.. With a long history dating back to 1993, the IEC 61215 standard has undergone multiple iterations, with the latest 2016 edition containing 19 tests designed to confirm the engineering quality of the solar modules.
Customer ServiceOn a sunny day, bring a standard 12V light bulb close to the panel, and aim it directly at the surface of the solar panel. If the light gets brighter, it usually means your solar panel is producing power accurately. If the brightness doesn''t change even after trying this test from different angles, it may indicate issues with your solar panel''s output.

Customer ServiceThese parameters create an ideal environment for maximum solar panel''s performance – no shade, no cloud, no wind. The amount of power a solar panel generates under the Standard Testing Conditions becomes its maximum power rating or nameplate capacity. If a solar panel outputs 400 watts at STC, it will be labeled as a 400-watt solar panel.
