It has been a season of fundraising and new partnerships in the off-grid sector. The latest announcement, this time from Greenlight Planet, illustrates the growing scale of private investment into the sector. The company raised $60m in debt and equity, as well as announcing a partnership with a new investor, London-based private equity company Apis Partners, to focus on developing a range of products with in-built pay-as-you-go (PAYG) technology, the latest in a stream of specialist investors into the sector.
