The day was rich and intense, with many intervention from top notch player in research, industry and tech transfer. I just wanted to share a few information about what stroke my mind.
The fact is here: Switzerland has been and still is at the forefront of PV development and research. Great news. Behind the labs wall, in white or clean room, engeneers are inventing, testing, building, all the component of the future of the solar industry. Flexible panel, pollution clean PV production, organic materials: everything exists and in many cases, could be or is commercially launched.
The true question is not about brains: we know we have them here in Switzerland. It’s more about hands… Hands to produce (labor cost), hands to acquire (local volumes), hands to push it to the next level (resources to grow). Interestingly enough, in China, labor cost is only 2% of the cost the solar panel. All right. So, I guess in Europe and CH, it could be … 10% ? Even with 15 or 20%, this is actually not the problem, as everyone, including me, would think at the first look. Adding to this that “Swiss Made” on panels would be a great sales argument.
So where is the problem? The issue is more in the size of the market: is the market big enough ? will there be a sufficient volume to sell what we produce ? Enough turnover to finance what we’ve invested to produce ? Even if those questions are still theorically open, the answer seems to be no. No, as investors are not yet interested to sufficiently finance product roll out. No, as government, did or are stopping their policy of supporting green energy production by buying it at higher price. No, as Swiss companies are closing (Flexcell in Yverdon) or acquired by companies that have a long, maybe longer, market vision (Oerlikon Solar, bought in Japanese company Tel).
An other interesting element is the cost in energy to produce the devices that produce energy… Yeah, it’s a kind of endless loop. Those cost are never accounted in traditional energy production – extraction is included in the cost of petrol and carbon footprint, but the co2 generated to produce the driller isn’t. It’s even less the case in the nuclear energy production, where the real massive cost are fully out of the equation. Indeed, waste management and dismantlement of nuclear plants have indeed a great future of making our electricity bill rise and rise during the next years as they not included at all in today’s cost calculation.
In that regards, PV and the solar in general is often criticized to be highly polluting when producing and possibly not efficient with weak sun. This was an other very interesting point I’ve learned at the conference. Indeed, unlike other that use their last energy reserve to dig deeper in the sand with their head, the PV industry and its research communities are well aware of those challenges, and in the process of solving them, one by one. To limit pollution, research are done to improve the techniques (it works), to find less polluting material (it’s close) and to fully capture all possible pollution at source (in progress). Sharper in those period of poor summers and cold spring, the question of the amount of sun and solar light is addressed with efficiency: increase the efficiency of each cell and of the panel (new material, sun chasing, angle adaptation) as well as selecting the most appropriate spot (i.e.: in CH, southern alpine region with a lot of sun).
At the end of the conferences, I had to moderate the debate between all the speakers of the day, some further invitees and the audience. It was not a easy tasks, as everyone was very passionate and eager to speak about his field of expertise. The debate lasted for 50 minutes, before some drinks and dinner served at the event.
From the debate, I’d like to highlight three ideas. First, a path of research with “biomimetic” technologies. Indeed, photosynthesis works well and there so much more things that nature could inspire us for. Indeed, nature is one of the only organization that already have invested 4.5 billion years in R&D to do great things. The second is the importance of the grid. Today, every production is really stable and constant, when renewable sources suggest for disrupted and irregular flows of production. Which creates big problems to the grid. Well, every one agrees that this gris is a bit “stupid”, as it can accept regular 50hz current, and could, should or would need to become “smart”. Smart grids are a huge topic in both the utility and the IT industry, throwing names like IBM, Cisco, Siemens, General Electric, Schneider in a common playing field. More than smart, the grid will also need to become flexible with more storage. We currently store energy on battery or by wildest means, such as pumping water back at the top of an altitude dam to produce new energy when the water passes through the hydroelectric plant while getting down. There again, there is tons of things to think and do, to plan and execute. Last but not least, the panelist identified the services industry as hug opportunity: no matter where PV are build, you will always locally grounded people to install, maintain and repair all those infrastructures.
In the end, the position of Switzerland appears me as great, potentially leading but needing some real and sincere reinforcement. We have an incredible amount of brains, research infrastructure and existing institution in the field. We had a great advance that we ‘ve have maintain, and that we stay still catch up. In my perspective, the main issue is velocity. A company like Flexcell had great product at acceptable price but were not time to market and did not had the resources to wait until timing was right. And timing is getting slower as government supports is decreasing and and as, current generation are paralyzed by the growing fear of the “size of tasks” of switching to renewables. This last point is what media, politicians and institutions can and need to change. All of those opinion leader must address a updated optimist message to the public and the decision takers.. Yes, it will be hard work, but a lot of fun too. Yes, work market will be disrupted but more qualified jobs will come out of it.
Yes, it will require change, but change for the better.
Yes, things will be different tomorrow, better or worse, it’s our current choice.
