SoliTek

This is the most sustainable and greenest Christmas tree imaginable. This project uses not only solar modules, but also an electricity storage system that will accumulate the electricity generated and then be used to light the tree itself. Thanks to this solution, the Christmas tree is off-grid.

This electricity storage system is in fact the first prototype battery produced by SoliTek. Mass production of these batteries will start next year in Vilnius and will be supplied not only to households in Lithuania but also abroad, followed by production for small and medium-sized enterprises.

Solar modules passed on to local kindergartens

According to Julius Sakalauskas, CEO of SoliTek, it is very important that this project is continuous and sustainable - the tree of energy-producing modules will not only light up itself, but also serve the city after the holidays: the dismantled modules will go to kindergartens, which will produce economical and green electricity for at least 30 years, the duration of which is covered by the warranty.

The tree is equipped with 42 bifacial 370-watt Blackstar solar modules from SoliTek, as well as 8 smaller custom-made solar modules with a nominal power of 150W. The total output of the solar modules is around 17 kilowatts, or 2 medium sized household solar power plants. During the summer, these solar modules would generate about 60-80 kilowatt hours of electricity per day. The SoliTek battery has a capacity of 15 kilowatt hours, which has been loaned to the municipality of Trakai for the festive period. (mfo)
