Dirt on solar panels is the primary source of power loss due to inefficiency for solar generation. Globally, this accounts for a cost in excess of €40bn p.a. and over 100Mtonnes CO2 emission. Conventional cleaning processes are costly and are water intensive. Existing self-cleaning coatings suffer from short lifespan (2-3 years), poor transparency and high cost (over €260/litre). SolarSharc® aims to bring to market a new patented product that for the first time will provide a durable, cost-effective and permanent self-cleaning solution for solar panels. This technology employs multi-functionalised silica nanoparticles that are strongly bonded to a coating polymer matrix, providing the qualities outlined.
Commercialisation of this new product will develop new avenues in supply chains, and aims to provide a return on EU investment within 5 years of sales. These sales will increase output from new solar installation by 63 GW, saving more than 10 Mtonnes of CO2 emissions. SolarSharc® aims to meet current customer needs in the market and deliver strong growth and a sustainable business for the consortium.
The overall objective actions of the SolarSharc® project include:
• Site test on solar glass prototype (TRL7) to demonstrate system benefits and obtain customer feedback.
• Optimise the formulation and process of SolarSharc® coating and BIPV panels to meet commercial product and customer requirements, including design for full operational specification, manufacturability, packaging and preparation for certification.
• Build and demonstrate production-ready coating on solar PV panels and BIPV modules through several trials on operational structures (TRL9).
• Ensure SolarSharc® coating and coated BIPV panels meet international standards required for solar farms and building operation.
• Develop training materials for coating process operators, building installers, sales force, and agents.
• Build market presence, sales and agents network.
• Achieve SolarSharc® BIPV module sales.
• Secure private investment to deliver SolarSharc® coatings sales growth post-project.
• Build supplier base and manufacturing capacity for initial sales and plan for capacity growth.
