Mauritius-based Investor Again Pours $2.5m Into Crypto-enabled Solar Energy Startup, Sun Exchange

Sun Exchange, a crowd-sourced global solar leasing platform, has announced that it has received $2.5 million in convertible note financing from ARPF, a Mauritian private equity firm advised by ARCH Emerging Markets Partners Limited in London (ARCH). This follows the company’s $4 million Series A capital round, which was spearheaded by a $3 million investment from ARCH, that closed in 2020.

“Addressing the climate emergency is the top priority on the world’s agenda, as evidenced by last week’s conversations at the UN General Assembly leading up to COP26. While policy action and diplomacy are critical at this juncture, the private sector and individuals have a crucial role to play. Powered by our global community, Sun Exchange closes the solar finance gap for organisations in Africa, addressing the challenge of our lifetime while supporting sustainable economic growth. We are delighted that ARCH has reaffirmed its belief in Sun Exchange and our mission through this investment,” Abraham Cambridge, CEO & Founder, Sun Exchange, said. 

Sun Exchange will be able to continue increasing its success by facilitating solar power for small-to-medium businesses in Sub-Saharan Africa, the segment most impacted by escalating energy costs, poor grid infrastructure, and costly backup diesel generators, thanks to the latest funding.

Why The Investor Invested

The Africa Renewable Power Fund is part of the funds under London’s ARCH Emerging Markets Partners’ management. With a size of $200 million, the fund has previously invested in Azimuth Solar Ghana, Achwa Projects 1 & 2 Uganda, among others. The Africa Renewable Energy Fund (AREF) invests into small hydro, wind, geothermal, solar, and biomass projects across Sub-Saharan Africa, excluding South Africa. This investment in Sun Exchange is therefore an extremely rare case. This is also the first blockchain-inspired cleantech startup to be backed from the fund.

“Sun Exchange continues to demonstrate momentum as a fast-emerging leader eliminating obstacles to solar proliferation in Africa. ARCH is committed to working with our portfolio companies and supporting their growth, and we are proud to continue partnering with Sun Exchange on its journey to accelerate the global energy transition,” William Barry, Managing Director, ARCH (Renewable Energy Strategy), said.

The basic idea behind Sun Exchange is simple:

  • You buy solar cells — the flat panels that produce energy when they are exposed to sunlight.
  • You lease them out to a customer, whose rooftops they will be installed. These are schools, hospitals, churches etc typically. Installation takes a few weeks after the project is fully funded.
  • The customer gets electricity from your solar cells and pays you for it. You just sit back.

The process itself is pretty simple, especially if you have a credit card.

  • Once inside, navigate to the currently available projects. Choose one you want to invest in.
  • Choose the number of solar cells you wish you to buy.
  • Choose whether you want your returns in South Africa’s currency ZAR or BTC (Bitcoin)
