“…There are many fields of application of photovoltaic systems in lighting, in [6] the use of a photovoltaic system for lighting in tunnels is presented, using the panels on the outside and carrying the energy to the interior luminaires, they can also be integrated into public lighting with grid connection and storage functions with batteries [7] or in interior lighting such as in offices or classrooms [8].…”

Photovoltaic systems have the advantage of reducing atmospheric pollution, avoiding 𝑪𝑶𝟐 emissions. Another advantage is the energy savings they produce and that in the long term they can return the investment made. PV systems off grids are applied in remote and rural areas, where there is no electricity distribution network. The use of PV systems off grids can be included in ornamental lighting, as they have low levels of luminous efficiency due to the use of old technologies. Therefore, this study presents a procedure for the design of PV systems applied to ornamental lighting, starting from obtaining adjusted values of solar irradiance, based on estimated solar irradiance data from NASA in the city of Cuenca (Ecuador) and measured data. The critical month (maximum consumption and minimum irradiance) is selected, which corresponds to June with a value of 𝟑, 𝟕𝟔 𝒌𝑾𝒉/𝒎𝟐 . The results indicate that these systems are feasible to be implemented, due to the fact that the total investment cost is around $10.450,00 compared to a 5,2 km grid extension system that costs around $44.512,00. Finally, the responses of the PV systems off grid applied to ornamental lighting are tested in MATLAB/Simulink.
