Contoh photovoltaic

• This is most likely to be achievable with the use of photovoltaic panels, primarily on roofs as a later installation.

• Light can be used in the facade by the incorporation of photovoltaic cells.

• And so the energy demand of buildings needs to be reduced and the reduced quantity of energy can be provided from renewable sources such as wind, tide, and photovoltaic cells.

• Statistical studies of learning curves for the costs of photovoltaic modules have shown costs to decline by 20 per cent for each doubling of cumulative production.

• The growth in energy use will unquestionably involve renewables, hydrogen, photovoltaics, biomass and the exploitation of wind and waves.

• Indeed, the proposal contains a number of derogations, particularly as concerns photovoltaic panels.

• Research on those matters suggests, for example, that photovoltaic panels have an energy payback time of two years or a little more.

• The typical payback period for photovoltaic installations is 50–100 years.

• Most houses could supply up to half their internal energy requirements from installed photovoltaics and/or from evacuated-tube solar water heating.

• Photovoltaic cells and solar panels are both being considered, and the position in respect of wind power is being reviewed.

• I could show you figures and curves here demonstrating that for both wind energy and photovoltaics this mathematical formula applies.

• Wind, solar energy, photovoltaic energy etc. only account for 5%!

• Although solar energy should be encouraged, photovoltaic modules contain materials that are at least as harmful to the environment as an electric toothbrush.

• For all those reasons, financial support should be given to a wider mix of renewable technologies, such as photovoltaics and solar energy.

• That is why we are backing biomass, photovoltaics and wave and tidal.
