narendra05556, welcome!
In parallel. Make sure you monitor and control the current supplied by both so as to not overcharge the battery.
Poor wording. Charging Lead-Acid batteries is all about controlling VOLTAGE(link); the current that flows into the battery is a function of the electrochemistry inside the battery. You need one voltage regulator connected to the battery; the two unregulated charging sources can be diode-ored into the input side of the regulator. That is how commercial "solar charging regulators" are made. These are readily available and cheap. Why build one?
