Discover troubleshooting steps for Solahart solar hot water systems not heating on cloudy days.
Cloudy weather can reduce solar energy absorption, affecting heating efficiency. Additionally, system malfunctions or blockages may contribute.
Consider using a backup heating source or optimizing system settings to enhance performance during low sunlight conditions.
Solar hot water systems rely on solar collectors to absorb sunlight and convert it into thermal energy. On cloudy days, the amount of solar irradiance is significantly reduced, which can lead to inadequate heating. The system’s controller uses temperature sensors to monitor the water temperature and may trigger a fault if the readings do not meet expected thresholds. If the inverter detects a drop in performance due to low voltage from the array or an issue with the temperature sensor, it may halt operation to prevent damage.
Users may observe that the Solahart solar hot water system is not producing hot water even during the day, particularly on cloudy days. Monitoring apps may show decreased energy production or flatlined temperature readings. There could be flashing LED indicators on the inverter or control panel indicating a fault condition.
Always ensure that any electrical work is performed by a licensed electrician or certified solar installer to prevent hazards and ensure compliance with local codes.
To avoid this issue in the future, ensure regular maintenance of the solar collectors, including cleaning and inspection of all components. Schedule annual checks for the temperature sensors and circulation pumps. Additionally, monitor the system's performance through the app to catch any anomalies early.
