How it Works

Join the solar revolution

The Sun Exchange lets you monetise sunshine in a few simple steps.


1. Sourcing and Evaluation

Sun Exchange identifies or is approached by a business or organisation that wants to go solar. Our team of solar engineers work with local construction partners to carefully evaluate the proposed solar project for economic and technical viability, as well as social and environmental responsibility. Projects undergoing evaluation are listed as “Coming Soon” on our Solar Projects page.

2. Solar Cell Crowdsale

Once a solar project is accepted, we host a crowdsale of the solar cells to power the project through our buy-to-lease solar marketplace. Any individual or organisation, anywhere in the world, can sign up to be a Sun Exchange member and purchase these solar cells for as little as ZAR 50 / USD 4 per cell, which are then leased to the project. Live crowdsales are listed as “Now Available” on our Solar Projects page.

3. Solar Cell Installation

Once all solar cells sell out (they go quick!), the chosen local construction partner installs your solar cells and the rest of the solar equipment. This process typically takes 4-6 weeks, but can be longer for larger projects. Your lease starts when the project goes live.

4. Generating and Selling Electricity

The business or organisation pays to consume the electricity your cells produce. You automatically receive this as lease rental payments net of insurance and servicing fees on a monthly basis, paid optionally in local currency or Bitcoin (BTC) into your convenient online Sun Exchange wallet.
