Raj Subramaniam is Senior Editor at Energy Clean Source, where he covers the technical side of photovoltaic systems — design, installation, inverter selection, battery integration, and grid interconnection.

Raj is an electrical engineer with experience in photovoltaic system design across residential and small commercial projects. His background spans system sizing, shading analysis, inverter compatibility, and the interconnection process with local utilities — a process that varies significantly by state and utility and is often poorly explained to homeowners.

At Energy Clean Source, Raj translates technical solar documentation into content that homeowners can actually use when evaluating contractors, reviewing installation proposals, or troubleshooting system performance. He covers panel technology in depth — cell efficiency, temperature coefficients, degradation rates, and what the specifications on a panel datasheet actually mean in real-world conditions.

He has particular interest in battery storage integration and the evolving economics of solar-plus-storage systems as battery costs continue to decline.
