Yes the voltage will always drop at night as you have no power. You might see 13.5 during the day but will always drop to ~12.7 overnight. With 15w for storage you really need to have all loads disconnected. Typically I would recommend 40 to 100 watts for storage. Even if you had 1000 watts the voltage would still drop off at night.
