I saw water coming out of my hot water solar panel.
Is this normal?

How to fix it?

  NAP but looks like it coming out of some sort of overflow / pressure relief outlet.

  Does the flow eventually stop?

    I think it stop at certain time. We are not sure, but most of the time I heard water running through our gutter n down pipe even though it is not raining.
    I just checked the roof today and find out that is what happening.

  If this was taken on a hot day then this would be understandable as it's the pressure relief valve, turn on a hot water tap inside and see if it stops.

  If you have a booster, it may not be turning off properly and may lead to overheating of the water.

  Mine was leaking at the connection to the valve (not the valve) due to corrosion, ended up getting 2 second hand panels for ~$500 installed. The installer said that during summer one panel (we have a two panel system) should be covered by a shadecloth or similar as the Australian sun is prone to overheating the system.

    It happen right now during winter, I will check again if it stops when I turn on hot water. Thanks

  It's the frost valve. I think it's normal if it stops. Google how they work.

  If it keeps leaking continuously, then that's a problem.
