Bull points

- In quarter one, we grew solar sales 80% year over year.
Bear points
- Our ramp is running behind our ambitious plans. Our wafer facility will undergo an extended maintenance shutdown, and we will transition to a permanent power system and repair and upgrade production equipment to increase throughput in future quarters.
- To cover this transition, we have built into our second quarter guidance $30 million of additional expense versus the first quarter.
- we had given guidance last quarter that CAPEX would be about $1.7 billion.
