Africa has the best solar resource in the world.
Despite having some of the best solar radiation levels in the world, the diffusion of solar energy systems in Africa has been very low
The linchpin to Tesla’s proposed merger with SolarCity is the Gigafactory and whether it can lower costs and improve battery performance.
Critics don't think Tesla can sell enough home batteries to justify its acquisition of SolarCity, but what they're underestimating is the potential for innovation the Gigafactory brings.
Windbacks to solar subsidies may encourage larger systems.
