Redefining PV Capacity

Effective metrics give solar its due credit.

Photovoltaic (PV) power generation is an intermittent, non-dispatchable resource generally considered as energy-only with no capacity credit. However, there is ample evidence that solar energy reliably is available at peak demand time when loads are driven by day-time commercial air conditioning, and can contribute effectively to increasing the capacity available on a regional grid.

PV vs. Solar Thermal

Distributed solar modules are gaining ground on concentrated solar thermal plants.

Photovoltaic technologies are beginning to appear more attractive than concentrated solar thermal plants. PV’s competitiveness is improving from technical and operational advancements, as well as significant commitments made by such utilities as Southern California Edison. In the long run, distributed central PV plants likely will gain a strong market position.

Solar Mandate? Like it or Not, Consumers Pay

States earmark millions to fund solar projects via system benefits charges.

Making solar power a realistic choice for electric consumers is a burgeoning issue for state utility regulators. As part of electric restructuring, regulators are trying to finance the costs of solar installations.

Key to delivering commercial, on-grid solar power to new markets are state efforts, partnered with other government and industry actions. So far, the system benefits charge, or SBC, is the primary short-term incentive to develop solar, wind, biomass and other renewable resources.
