Drone shot of Welverdiend Retirement Resort.

We’re thrilled to announce the next Sun Exchange solar project crowdsale, set to go live Tuesday, 4 June, will be for Welverdiend Retirement Resort in Cape Town, South Africa. This 94.6kW project will reduce the costs of living for retired South Africans.

One of the key reasons is that with today’s higher standards of living and longer life expectancy, retirement has become increasingly costly. There is also a strong sense of responsibility towards future generations.
