Solar geyser evacuated tube removal method.
The first place to check is the plumbing pipes above the water heater.

Draindown or drainback systems typically use a controller to drain the collector loop automatically.
If the water inside the unit gets too hot usually above 210 degrees or pressure builds up too high above 150 psi the water heater can become damaged or even explore.
Solar water heating systems that use a pump called active are more expensive but also are more efficient than solar heating systems that use gravity for water circulation called passive systems.
This generally happens in summer when the tank is too hot and the valve activates to release the super heated water from the tank.
A drip from above can easily leak down on top of the water heater and even work its way down the insulation and make it look like the leak is coming from the tank itself.
