ABSTRACT OF THE DISCLOSURE The invention disclosed is a liquid constant flow, drainable solar energy collector system in which a manifold feeds several evacuated glass tube solar collectors disposed on an upward side of the manifold. The collectors are fed in parallel through an individual orifice which restricts flow rate to each solar tube. The normal outlet of each solar tube is via an axial glass pipe which extends to its top region. The orifices are all connected to a common header pipe in the manifold and the glass outlet pipes are all connected to a separate common header pipe in the manifold. For each solar tube the outlet pipe is of sufficient diameter in relation to the orifice so liquid that overflows the pipe does not completely fill it and allowing an air vent passage via the same pipe. The restricted orifices are provided by inserts removably installed between their common header pipe and the solar tubes. The manifold is sloped to its drain and the collectors are sloped to the manifold providing full drainability; and the collectors may use pure water without danger of freeze up or need for anti-freeze mixture.
