Plug-In Solar Is Moving From Workaround to Mainstream
A practical guide to what plug-in solar is, where it is legal, what legislation is moving, and how to choose the right system package and components.

Full cost and value accounting for distributed energy resources
Our Solar Siting Surveys, interconnection analyses, and cost-benefit analyses show the value of clean local energy in specific locations — which results in more projects being built.
The Clean Coalition conducts Solar Siting Surveys to help utilities, CCEs, cities, and communities assess the potential for local solar generation.
Our Solar Siting Survey methodology evaluates all prospective solar sites and the interconnection hosting capacity for each site. The methodology assesses the technical siting potential for built environments, including rooftops, parking lots, and parking garages, which are essential for procuring wholesale distributed generation (WDG).
Interconnecting a wholesale distributed generation (WDG) project to the grid can involve uncertainty and extra costs. That discourages many projects from getting off the ground or even being considered.
The Clean Coalition’s interconnection analyses ensure that projects can be connected to the electric grid without expensive infrastructure updates — and give developers the certainty they need to proceed with WDG projects.
Most municipalities, load-serving entities, and businesses will not build a clean energy project — or adopt energy efficiency measures — if it’s not cost-effective.
The Clean Coalition’s cost-benefit analyses show these entities which projects are worth developing. From the monetary value of resilience for Community Microgrids to the payback for LED lighting conversion in commercial buildings, our analyses provide details on costs, savings, and payback times — including how to bundle costs to increase savings.
