REDAVIA is an industry leader in solar power. We provide solar farms to businesses and communities in West and East Africa. With a proven track record in cost-effective, reliable and clean energy, REDAVIA is committed to using solar energy as a key driver for sustainable development.

The innovative REDAVIA pay-as-you-go system consists of a pre-configured Unit containing solar modules and electrical components. Once the Unit is on-site, our REDAVIA-trained, local specialists manage the installation, operations and maintenance of each solar farm.

Our carbon neutral solution can be used to support existing power structures by supplementing the utility grid or on-site diesel generators. Through our flexible lease agreements with just a minimal upfront investment, our customers can reduce costs and increase their operational flexibility.
