Surfer Today features articles about the "perfect quiver" of surf boards to match varied conditions. Power kites are similarly best used as a quiver, to match wind to load across broad conditions. Not only does a range of kite sizes extend action across a wider wind range, but no single kite failure stops the action. Under proper care, a kite quiver is immortal, with only occasional replacements and upgrades.

For a power kite that is not intended to fly humans*, the working lifespan of a well maintained wing is an open question, a few thousand hours, at least. Large SS power kites may someday pay for themselves in as little as three weeks, at market energy rates. Power kites are quick, cheap, and easy to repair. Its known that carbon black pigment essentially solves polymer UV life. As porosity is lost, a simple retreatment restores zero porosity. Working kites may fade or stain, but keep working a long time.

kPower proposes that power kite lifespan be tested realistically, in quiver rotation, to correct undue pessomism about how long such kites can last. Testing by multiple companies is showing that one-size-fits-all rigid-wings hardly survive a two days of AWES operation, with pay-back requiring several years of survival. A quiver of soft kites is comparatively immortal, and cheap.
