A New Generation Grid-Inverter

The high AC and DC voltages have the advantage that line losses can be reduced almost everywhere in the system. Firstly, in the inverter, which forms the part of efficiency gain, and secondly the cable losses in the PV installation, which will be significantly lowered. In addition, the installation costs for cabling and the associated costs are reduced.

Grid Parity

Grid parity happens when large scale solar can compete with, or beat wholesale pricing from coal plants, the nuclear facilities and combined cycle natural gas.

Improving Performance and Reducing Maintenance of CSP Systems with Copolymers

Chamelic is a spin-out company from the Faculty of Engineering at the University of Leeds. Chamelic Ltd was established in February 2006 to exploit innovative chemicals discovered and developed at the Institute Particle Science and Engineering (IPSE).

Better Buildings, Better Plants

The Department of Energy's intention behind the showcase project is to have leading companies create "blueprints" of their energy saving tactics that are actionable by a broader set of US companies. By creating an aggressive goal for a single facility, it affords a focused experience of what it takes to achieve that goal. We plan to be transparent in our actions in order to create these repeatable solutions for other companies.
