Two „MARAMA SOL“ fully automatic, solar-powered, self-learning luminaires were installed and started testing in Pašilaičiai and Antakalnis districts in Vilnius. Our goal while creating this type of solar-powered luminaire was to design it in a way, so it would efficiently operate in any geographical condition. This pilot project of the company “Vilniaus Apšvietimas” will let us evaluate the possibilities of using this type of luminaires in Lithuania, where the amount of sunshine isn’t high during the winter season.
One of the lights is being tested in the Pašilaičiai district, Baltrušaičio street, in a green space between residential buildings, and the other one – in Antakalnis district, Bistryčios street, in a children playground surrounded by trees. These two different environments were selected specifically to evaluate the efficiency of the luminaires under different conditions, all year round.
The demand for such luminaires is growing rapidly- they combine the advantages of environmental, economic, and smart management. Stand-alone, solar-powered luminaires would be particularly useful in locations away from an electrical outlet.
„MARAMA SOL“ features an innovative energy management system based on IoT (Internet of Things) technology. This management system consists of several elements, and one of them is a special software designed to analyze historical weather data and compare it with weather forecasts. By analyzing this weather data and matching it with the luminaire battery charge and power consumption data, the system itself determines the most efficient lighting mode. In this way, this self-learning device strikes a balance between the produced and the consumed energy.
Key features of MARAMA SOL:
- MARAMA SOL luminaries are compact, easy to transport, to assemble, to transform or upgrade using a system of modular components.
- As it is an autonomous, self-managing and self-learning system, it requires little to no maintenance.
- MARAMA SOL optimizes energy consumption by switching the light on or off and changing the light intensity if necessary.
- The users have the option to intervene and change the system’s plan. The lighting regime can be altered by just a couple clicks on a smartphone app.
- MARAMA SOL luminaires can operate in groups by sharing data.
- Photovoltaic panels are mounted vertically which optimizes the collection of solar power and prevents the gathering of dirt.
The efficiency and progress of smart luminaires installed in Vilnius will be monitored throughout the year.
The final version of MARAMA SOL v.1 is scheduled to reach the market this year and MARAMA SOL v.2 (with cylindrical solar panels and LEGO-type modifiability) in 2022. Both products are scheduled to be presented at LIGHT ME 2021 (Dubai) and LIGHT+BUILDING 2022 (Frankfurt Main).
