Evaluating the Cleanliness of Solar Photovoltaics Can Be Complicated : CleanTechnica - 0 views

  • Take a good look at panels that have been installed for several years and you will notice discontinuities and shiny areas where the components have been damaged and where the power production is reduced.

      There's an idea. Only once I've seen a paper on long-term performance of panels.
  • Though there are no visibly moving parts in a solar PV panel, there are many parts of the system where continuous chemical and physical reactions take place that can eventually lead to system degradation and failure.

      Makes sense. Roofs have no moving parts as well, yet we're always concerned of infiltrations.
  • Leaves and snow are particular nuisances for rooftop solar panels, but sand and bird droppings can be important in some areas as well.

      Few solar advocates are part of the BC sector.

    Solar photovoltaic (PV) cells are a popular and often discussed (see, for example Atlantic City Convention Center Plans Largest Solar Roof in U.S., 10% of U.S. Electricity From Solar by 2025, SF Passes Largest City Solar Program in U.S. (Finally), all of which were published within the past week) form of "renewable" or "green" energy, but a casual scratching of the surface knowledge that many people have about the technology reveals some troubling details.

shared by Hans De Keulenaer on 02 Feb 09 - Cached
  • A brief general picture of the world, european and italian energy situations is made, analyzing several different energy sources and paying attention to the relations energy-quality of life, energy-environment and energy-health. Then will be discussed fossil fuels, renewable energies, the role of electric energy, nuclear energy, energy savings, the greenhouse effect, a possible sustainable development, the hydrogen economy and the risk and its perception. Then follow the conclusions and perspectives.

    This recent article by the Manager of EPRI published on EnergyCentral.com discusses how conventional photovoltaic (PV) applications can act as distributed resources when the sun is shining -- rather than solely as a reduction in load

Smart grid and renewables interconnection (Part 4 of 5) - 0 views

shared by Energy Net on 09 Mar 09 - Cached
  • Energy Net on 09 Mar 09
     
    One of the reasons why smart grid is generating so much interest right now is its ability to enable the integration of renewable energy into the electric power network, leading to a broader generation portfolio and potentially beneficial carbon implications. Lots of the discussion of smart grid in policy and media (including places like Greentech Media, Cleantech, EcoGeek, GreenMonk, and the New York Times blogs Dot Earth and Green Inc.) has emphasized the potential economic and environmental value from having investments in the electric power network that make the accommodation of renewables easier, reducing transaction costs and shifting the margin at which investing in renewables is profitable.

  • So on July 10, the Edison Electric Institute hosted a lunch at the Waldorf-Astoria Hotel in New York City. A six-member panel of EEI representatives addressed journalists to discuss "the effort underway to transform the role that energy efficiency plays within the electric power sector," according to the event program.
  • The EEI is the association of U.S. shareholder-owned electric companies, and its agenda is to ensure that its members turn a profit.

shared by Hans De Keulenaer on 29 Dec 08 - Cached
  • Unsettlingly, usually, these discussions involve more strong opinions than data. Some people believe that one of these alternative (they are not all sustainable) energy options is the silver bullet that will solve both the climate and the energy crisis. Other argue that there is no silver bullet and that what is required are a variety of silver BB’s: a mixture of technologies, along with greater energy efficiency and preservation of habitat (forests). Do we really just need to build huge number of nuclear plants or wind farms to solve the problem? If, instead, we are going to use a mix of alternative energy sources, which ones should we use and in what quantities?
