I think they knew solar is the future, all around the world.<p>China has massive pollution, and most homes/businesses that have access to direct sunlight. (Yes--I know solar works 50% on cloudy day. It doesn't work well with a lot foliage coverage. China looks barren of trees--sadly.)<p>My hope is those solar tiles come down drastically in price. My hope is the average roof will be cost effective to put said tiles up.<p>I think those solar tiles will be Tesla's Trump card. It will probally be in four years, or more in the United States. We will need a new president. (I was for Trump putting Coal miners back to work, until I found out the problem is not regulations, but automation. Actually, I want clean air. We need a better way of supporting people affected by the elimination of old ways of doing things; like a Basic Income.). Sorry about being all over the place, but there are no simple answers. Trump is just finding this out.<p>I think Tencent saw a long value in the stock, even though their citizens will not likely buy Tesla's tiles. They will buy the cheapest knock-off as usual, but the rest of the civilized world will buy Tesla's product.<p>(I don't know what patents are on these new Tesla tiles, but I bet they are seen as a valuable commodity, even to a cheating society like China.)
