SPS Investments previously operated under the ‘Mettle Solar’ brand. We focus on providing innovative funding solutions in order to provide businesses across Sub-Saharan Africa with access to high quality solar and battery solutions. In 2015, we acquired a 50% interest in Sustainable Power Solutions (SPS), one of Southern Africa’s leading solar engineering firms.

This acquisition allowed us to provide seamless funding and engineering solutions to our clients, all within one group. Since 2021, Mettle Solar and Sustainable Power Solutions started to conduct their respective businesses under the single ‘Sustainable Power Solutions (SPS)’ brand.

The UK’s development finance institution,  British International Investment, is the largest shareholder in SPS Investments through their wholly-owned subsidiary, Gridworks. British International Investment also provides debt funding to our projects across the jurisdictions in which we operate. This debt facility enables us to offer our clients and developer partners fully-funded solar and storage solutions in a cost-effective manner.
