Investec plans to offer its private banking clients funding to install solar panels and battery storage systems in homes, bolstering its own green credentials and providing a power solution in a country regularly hit by electricity outages. The offering, which follows a pilot programme for 1 000 customers in South Africa, will allow clients to tap unutilized home-loan facilities or have money re-advanced to them to put in place the systems that can cost about $10 000, or significantly more depending on the size of the property.
