Guinness Sustainable Energy Fund on First Solar

Thesis

The fund owns First Solar for integrated exposure to solar-cell and module manufacturing using a specialist cadmium telluride process. The managers expect solar to remain a major source of new generation because of competitive costs, fast deployment and rising electricity demand. First Solar's differentiated manufacturing technology gives the portfolio solar-equipment exposure distinct from standard polysilicon producers.
