They went a sunny-route through the panama-channel and not the route trough Kap Horn and the Kap of good hope, which is normally taken by round the world sailors. These routes have a high chance of storms, which come with clouds. 3 days of clouds would have rendered the boat unmanoeuvrable. Nice experiment but solar powered boats are absolutely useless on high seas and better, cheaper and a lot more ecological (a lot of energy goes in the production of solar panels and batteries) alternatives (sailboats) have been around for ages.
