Frequently Asked Questions
When will Saule solar panels be available for purchase?
Currently, we are developing our prototype production line, and it is planned to be operational during the 4th quarter of 2019. Our products and exact details about their prices thus will be available later.
Will Saule sell panels to individual customers or companies only?
Saule products will be available to business clients, so companies mainly. We are focusing on B2B (business to business) model targeting construction, electronics, automotive and space industries. However, it is possible that our products will be available for individual customers through our client’s distribution network.
I would like to test your panels at home or some small private construction, what should I do?
We do not provide our technology for testing until we have a commercial product available. We invite you to subscribe to our NEWSLETTER so we can keep you up to date.
My company is interested in the implementation of perovskite solar cells in our products, what should I do?
Please email us at firstname.lastname@example.org with a brief description of your project. Let us know what your company is doing, what the name of the company is, where you are based and what your role in the organization is. We will contact you back in 24h.
What is the cost and efficiency of the solar cells by Saule?
We expect the initial efficiency to be around 10% and the initial price to be around 50 EUR (58 USD) per m2. This would mean the LCOE (Levelized Cost of Electricity) of approximately 0.05 EUR (0.05 USD) per kWh. We predict to increase our module’s efficiency to 13-15% in the due course, meanwhile, there is a lot of room for future product price reductions.
What is the lifetime of the product offered by Saule?
We expect an initial lifetime to be several years, which will be improved in the due course.
What will be the final shape of the panel?
The inkjet printing technique allows the design of free form perovskite solar modules. The shapes and areas covered by each layer can be all customized according to the requirements.
What does it mean that cells are flexible?
Perovskite cells are resistant to damage caused by bending and folding. The flexibility of the final product depends only on the materials constituting the substrate and the encapsulant. The technology is compatible with virtually any substrate. Currently, developed cells are printed on a flexible, transparent foil.
Can I install perovskite cells on windows?
Yes. Different levels semi-transparency is obtainable. Even though the efficiency decreases with increased transparency, it is still economically viable due to the intrinsically low cost of our technology.
What is the thickness of the module?
The thickness of a solar cell is around 1 micron. The total thickness of the module depends only on the substrate and encapsulation technology.
How heavy are perovskite modules?
The weight of the solar cell is negligible compared to the substrate and encapsulants, and the total mass thus depends on the materials of these components. Current weight of Saule modules is approx. 500 g/m2.
Can you modify the color of the cell?
The technology utilized by Saule enables the finished product to be engineered to a wide range of available colors. This is a feature especially desirable in building integrated applications, allowing architects to design with a great degree of freedom.
