When replacing a freeze valve I would, turn off pump and cold water to tank, open a hot tap or tank p&t valve to depressurize and leave it open to keep any pressure from building up. Pull old freeze valve, if it''s at the bottom of array turn on the water for a moment to flush the dirt out. Replace valve and test for leaks.
The leaks may be coming from the temperature sensors or pressure valve on the solar heating system. This may mean the valve or seal may need replacing. The leaks may be

Solar water heating controls consist of a temperature sensor on the solar collector outlet, another at the bottom of the solar storage tank, and a circuit (delta-T controller) to start the pump when the collector is hotter than the tank and stop the pump if its not.
Expansion vessels are an important part and safety device of your solar hot water system. The expansion vessel allows your system to expand in case of increased system temperatures or during stagnation. Do I need to regularly replace my solar expansion vessel?
the Schrader (car type) valves often fail. We can replace the valve and can pump up the vessel with air to the correct pressure (not Nitrogen as originally supplied). If the mild steel expansion vessel is corroded and pin-holed, we will need to replace it. See below for samples of failed expansion vessels.
