I would stay with this solar system. The nearest alternative is 10.5 light years away and the Person 424 is not capable of the jump to light speed
The cheaper flexible panels are always a bit of a gamble. The lifespan on some can be reasonably short. However, the panels you have chosen have some good attributes. They use Sunpower cells and the panel is a defined brand (although I had never heard of Windycity before I Googled them). The top quality flexible panels like Solbian are much more expensive, so I think panels like the model you have chosen are a reasonable choice, although you wont know for a few years if cost/lifespan ratio is acceptable.
The cheaper MPPT controllers don't have a good reputation and I think it would be worth upgrading to something like the Victron or Genasun. There is a lot of debate about series/parallel connection (see some recent threads on this subject) or even better wire them up temporarily both ways and report which is best. The Victron charger
is perhaps not ideal for parallel connection. 2 x Genasun GV10 controllers (so each panel has its own controller) has some appeal for this size installation
, although it would cost another $80 or so for the two controllers over the single
model you have listed.
There are a lot of cruising boats without a fridge, so I would not automatically assume one is fitted. Without refrigeration
200w is a reasonable amount of solar. In the days when solar was very expensive, I have cruised with much less. As others have mentioned, an LED anchor light is almost an essential upgrade.

No, monocrystalline celłs like your panels have are usually slightly more efficient, although the difference is not great. It is easy calculate the panel efficiency once you know the rated wattage and size. For your panels it is 17.5%, which is not state of the art, but good still very good for this type of panel.
Good luck. Solar panels
are great, and it is well worth the trouble to sort out the best choices.
