Power outages are a reality for millions of households and businesses. But the real problem is not simply the absence of electricity. It is the absence of a reliable, durable solution that is genuinely adapted to each specific situation.
Too often, equipment is sold without any prior analysis: an undersized system that fails at the first consumption peak, an oversized system that wastes budget, hardware with no serious warranty, a supplier who disappears after the sale. The financial losses caused by breakdowns, damaged electronics and interrupted operations accumulate — without the situation ever truly improving.
Add to this the difficulty of choosing the right energy source: solar, generator, hybrid, storage only — each situation calls for a different answer. Without objective technical advice, the client is left alone to evaluate offers they cannot properly assess.
Our role is not to sell panels. Our role is to analyse your real need — your installation site, your consumption, your constraints, your budget — and recommend the most appropriate energy solution. We size, install, secure and remain available after every installation.
We do not sell equipment off the shelf. We design solutions tailored to each client, each location and each budget — with a long-term commitment.
Before any installation, we analyse your actual consumption, installation site, technical constraints and budget. No recommendation is made without this preliminary step.
Calculation of required power, selection of the appropriate technology, equipment specification, real autonomy estimation. Every parameter is justified and documented in the quote.
Monocrystalline or polycrystalline panels, off-grid or grid-tied solar systems, storage solutions, hybrid systems. We handle projects of any scale.
Lead-acid, GEL or Lithium LiFePO4 batteries selected according to usage, cycle frequency and desired warranty level. Autonomy configurable from a few hours to several days.
Installation and configuration of hybrid inverters, MPPT or PWM charge controllers, DC/AC converters suited to each setup. Commissioning and full system testing included.
Solar and generator combination, automatic switchover, intelligent source management. Designed for businesses and sites requiring guaranteed continuity of service.
We manage importation, reception and verification of all equipment. Every component is checked before installation. Lead times are communicated and respected.
Maintenance contracts from 15,000 FCFA/month. Panel cleaning, connection checks, battery testing, inverter control. On-site intervention within 48h, unlimited WhatsApp technical support.
The client selects their warranty level based on budget: entry-level (6 months), standard (1–3 years), premium (5–10 years), excellence (15 years). Each option corresponds to a precisely defined and documented equipment range.
