PHOTOVOLTAIC CLEANING

This challenge looks for innovative, cost-efficient and eco-friendly solutions to clean solar PV panels in large scale plants. It is envisaged that in the areas were solar PV plants will be built, there will be water restrictions, so waterless approaches are desirable.

The main features that will be considered are the following:

• Fixed or Portable solutions that can be utilized for several PV plants close together
• PV plant configuration: fixed-tilt or single axis tracker installations
• Remotely operated solutions and/or fully autonomous solutions
• Solutions to prevent stick stains
• Solutions to dissolve and remove stick stains
• Solutions energy independent from the plant

Proposals should be applicable for any (or all) of these cases PV power plants bigger than 100 MW with:

• fixed-tilt (3 vertical panels per string, 2 meters’ high each)
• multi row single-axis tracker – one panel per string
• one row single-axis tracker – 2 panels per string
• or a generic solution applicable for different types of plant configurations

You are welcome to submit more than one proposal, just make sure to submit a separate application for each.

There are many reasons why you should apply for this Challenge:

• The Challenge offers the possibility to test the technology in Iberdrola's Renewable Facilities.
• If the pilot succeeds, Iberdrola will add solutions to the current portfolio of providers to improve the O&M in their PV plants. Besides, Perseo, the VC arm of Iberdrola, could consider an investment.
• The Challenge offers the possibility to scale your technology into Iberdrola's pipeline (14,000 MW of Solar Photovoltaic Panels).

The winner of the challenge will sign a collaboration and testing agreement with Iberdrola Renewables and/or any other relevant company of the Iberdrola Group.

Iberdrola and/or the relevant company will:

• bear the costs of such collaboration and testing activities
• provide the technical support to test the solution proposed, granting access to equipment, teams, infrastructures, high-tech locations, and co-working areas
• provide a real environment and data to test the solution
