  3. Pros Precise Dual axis Return to sunrise position for earlier start Ignore temperature Shipped in parts 30% average increase in received solar radiation in Vermont Cons Less reliable Sensitive to lightning Higher initial cost Uses electricity, but only about 5 watts/day Active

  4. Passive: How it Works Mid-Morning Sunrise “Wake Up” Mid-Afternoon Sunset

  5. Pros No electrical parts Reliable Simple Cost competitive to stationary mounts Cons Morning wake up (must return to sunrise pos. from sunset pos.) Slow to react Sluggish in cold weather More expensive to ship Prone to wind gusts Horizontal axis only Passive

  6. Pros Most reliable Cheapest Off-the-shelf parts Cons Vertical Adjustment Least Sunlight Captured Labor-intensive Manually-Operated
