Why invest into these kind of projects?

There are places in the world where these systems can be profitable NOW.The returns are so secure that they are almost uncorrelated to the future economic environment. Access energy and certificates are an additional upside and future technology upgrades can boost returns.

Renewable energy systems are already competitive in off grid situations

Increasing fuel and emmision credits costs

Innovation and economies of scale reduce the costs for renewable energy technology components

Fossil fuels

RenewableIsland systems from a few kW to a few MW (island or remote situations)

Let the fossils rest in peace
