  • A brighter future for solar in Texas

    I'd put my money on the sun and solar energy. What a source of power! I hope we don't have to wait until oil and coal run out before we tackle that. - Thomas Edison, in conversation with Henry Ford and Harvey Firestone, 1931 According to the State Energy Conservation Office (SECO), Texas has the greatest solar energy potential of any state in the country. “If photovoltaic (PV) systems operating ...

  • Solar Energy and Power Importance

    Have you ever wondered why solar energy or power is important? You are not alone in this because it is the common question of all. Before we can understand why solar energy is important we should have a good idea of what solar energy is. Solar energy is produced by the sun. It can be harnessed like any other type of energy and used to ...

  • New Antenna, merged with solar panels

    The EPFL researchers have managed to merge antennas and solar cells in a mixed device that promises unprecedented efficiency. It is a first step towards the development of more compact and lighter satellites, but also to the improvement of mobile communication systems used in case of disaster. Traditionally, telecommunication antennas and solar cells do not mix. They must function independently ...

  • Market penetration and pay-back period analysis of a solar photovoltaic system under Indian conditions

    The use of pay-back period analysis for economic evaluation of solar photovoltaic (PV) system reinforces the importance of the duration of the system. In a dynamic economic environment, the cost of energy increases at a faster rate than the common inflation rate. A time can be ascertained at which the market entry of the PV system will be profitable, i.e. at which the pay-back time drops below a ...

  • Near Term Lower Cost Solar Electric Power for US Commercial Customers

    Market Opportunities The first market for PV electric power panels was for space satellites. While the single crystal cells used in these panels made these panels very expensive, this was unimportant for that market. That market emphasized reliability, not cost. As these panels came down to earth for off-grid remote applications, again the emphasis was on reliability and low maintenance, not ...
