Ultimate Electric, Inc. has just developed a solar panel capable of generating 200 percent more electricity than any solar panel currently on the market. As a result, Ultimate is expected to experience a 15 percent annual growth rate for the next five years. When the five-year period ends, other firms will have developed comparable technology, and Ultimates growth rate will slow to 5 percent per year indefinitely.
