According to the client's requirements, the solar systems should:

• Be strong enough against animal's damage;
• Have stable performance for the continuous cloudy or rainy days;
• Be slim enough duo to the strong wind.

The vertical solar tube has less space with IK08, so it could meet the above requirements.

The solar modules are 6 pcs in a circle, it has stable power output no matter in the morning or in the afternoon(it has less power when around at 12:00). And the aluminum housing holding the solar PV modules, make it IK08 against strong wind or other pressure.

So this 120W vertical solar tube can meet the requirements.
