Identify a low-cost cleaning solution for large numbers of tightly packed solar PV systems.

What it does

The application of protective films to protect solar panels from dust and the implementation of a centralised cleaning service

How I built it

The system require the installation of a roller for each row of solar panels and a set of clamps that keep the interchangeable plastic layer in place. The system has two repositories: one for clean sheets and another for used sheets. Once the repository for used sheets is full, used sheets are taken to an off-site location for cleaning.

Challenges I ran into

One of the main challenges was to determine if there is a material that is suitable to use it as an extra layer. The plastic need to have high light transmission and resist outdoor conditions.

Accomplishments that I'm proud of

We are prod of organising our thoughts and came up with a solution that is better than our original skecth.

What I learned

We learn a lot about solar panels and how to tackle difficult problems.

What's next for Pure Grid

Do the prototyping and perform a feasibility study.
