The snobs at the "pro" forum have a long thread that thoroughly bashes and ridicules these units.

Solar Assisted A/C

The unit under scrutiny was a sedna aire. OEM is Westinghouse, sedna added the collector. A test tech that worked for Westinghouse stated the modified unit did not pass their testing procedures, so the OEM warranty was invalidated prior to release of the product. Sedna eventually released the line of products anyway. So in a way, the units were doomed to fail even before any were sold.

The mini split unit is not the problem. The solar collector is not the problem. But when you combine the two, that's where the problems begin. During warm, sunny weather, the solar collector pours its heat into an already hot compressor. The compressor quickly trips out on thermal overload. Meanwhile, the solar collector is allowed to stagnate, and is temperature skyrockets. When the compressor cools enough to reset the thermal overload, it is immediately fed overheated gas. This vicious cycle continues to roast the compressor until one of two things happens: either the sun goes down or the thermostat is satisfied. After a sufficient amount of abuse, the plumbing leaks or the compressor burns up.
