Operation

Using a quality water source is crucial. Water containing high concentrations of bicarbonate, calcium, magnesium, and salts may create sediments in the long run. Adequate water treatment is recommended to reduce water hardness. For optimum performance, operate the NEX Clean units daily, preferably early in the morning, to take advantage of the dew on the panel surface which enables cleaning with less water. The optimal duration of operation of the NEX Clean units varies from 15 to 25 seconds, depending on the severity of the surrounding conditions and the amount of dirt build-up.

 

  • The unique, adjustable NEX Clean unit fits most panels in the market.
  • The NEX Clean unit maintains steady, well-aligned microsprinklers on the panels for optimal, uniform cleaning.
  • The NEX Clean unit is free of vibration and abrasive effects on the solar panels.
  • All components are modular and easy to assemble without a need for special tools.
  • Easy, user-friendly assembling and dismantling of the unit on the panel.
  • Two kinds of water distribution for best coverage of the area: The main NEX Clean unit consists of a 180° static diffuser, while the second NEX Clean unit consists of a 90° static diffuser for use on the edges and boundaries.
  • Non-rotating parts for long life span even under tough conditions, such as high temperatures, wind, and dust.
