Why is my solar hot water pipe leaking oil?
We have a solar hot water panel and one of the pipes coming from it seems to be leaking an oil-like substance, presumablythermal transfer fluid. The pressure gauge is showing zero bar, so once it's fixed it will likely need topped up. The leak is coming from a specific joint in the pipework, where the flexible pipe meets the fixed pipework.
What happens if a heat pipe freezes?
At least if a heat pipe freezes only the heat pipe needs to be replaced. Since the tubes are bad why not try poking a hole in the rubber and see if they are still holding a vacuum. My guess is they are not. That is the biggest failure point on that design of tubes.

Solar power generation thermal efficiency
Photovoltaic modules are tested at a temperature of 25° C - about 77° F, and depending on their installed location, heat can reduce output efficiency by 10-25%. As the solar panel's temperature increases, its output current increases exponentially while the voltage output decreases. The conversion efficiency of a photovoltaic (PV) cell, or solar cell, is the percentage of the solar energy shining on a PV device that is converted into usable electricity. For example, if a solar panel has an efficiency rating of 20%, it means that 20% of the sunlight hitting the panel is converted into electrical energy, while the rest is reflected or lost as.
