Switching to renewable energy is a strong environmental incentive. It sets in motion the United Nations’ Sustainable Development Goals (SDGs) while being an opportunity to promote green energy solutions and inspire local economies to adopt similar solutions . Aptech Africa was entrusted with installing a 15kWp hybrid solar system to further the above incentives.
Going solar means reducing approximately 3.7 tons of CO2 emissions yearly, effectively reducing the office’s carbon footprint and burden on the environment. The solar installation in the Republic of Congo will enhance business continuity all the while promoting sustainable development in the region.
Initially, the energy supply for the premises was based on a diesel generator of 66 kVA and a very unreliable electrical grid with power outages of about 3-6 hours per week. These interruptions of ongoing office activities posed ineffectiveness. The use of a diesel generator also caused high levels of air pollution. With installation of the Solar PV system, there is reduced fuel consumption and costs of maintenance.
The system located in 14 Rue Behagle Centre Ville, is a single 15kWp system with a battery storage of 34kWh. The solar panels are roof mounted and the system is integrated with the existing generator. Ulica 540W panels, Pylontech US 3000C Victron Quattro 48/8000 with two Victron MPPT 450/200 RS solar charge controllers and remote controlled firefighter switch were used in implementation of the project.
The entire system can be remotely monitored through the Victron Remote Monitoring System that was installed on site to communicate the Battery State of Charge; PV generated power, supplied power as well as fault detection, which assists in allowing early problem detection and preventing future damage to installed equipment.
