  • Solar hot water system

    Solar hot water systems (e.g. residential) do not produce steam, for example. Thus, solar hot water systems cannot push a steam turbine and will not generate electrical power. Solar hot water systems are used for heating and hot water requirements, not electrical power. If this is offsetting electrical hot water or electrical heat, then these are more like 'negawatts' than Terawatts. Steam ...


  • The Effectiveness of Combined heat and Power Solar Water Heating Systems

    Abstract: Solar water heating in residential and commercial buildings is often provided by integrating a large number of domestic thermosyphon solar water heaters. The economic effectiveness of solar Domestic hot water heating systems depends mainly on its types and configurations. Thereupon in this paper, simulation models have been presented for the modeling of thermal and electrical ...


  • Water vapour permeation measurement for PV Solar Cell packaging

    With fears of carbon dioxide causing global warming and diminishing supplies of fossil fuels, a looming energy crisis is affecting all countries.  As a consequence, a great deal of world-wide effort is going into the development of alternative energy technologies.  At present, wind, hydro and geothermal are becoming well established with more niche roles for tidal and solar. The latter ...

  • Tips on Cleaning Your Solar Lights

    Solar lights are not a common part of life or lighting in many households but they are gaining a bit of ground. Most of them are used outdoors and this means that they will definitely get dirty after a while. These lights require regular maintenance but the fact that these lights are placed outside means that you will probably check on them less often. You will find no moving ...

  • Get more Bang for your Buck with Solar Thermal!

    The relative efficiency of renewable energy technologies – i.e. their ability to transform solar or wind energy into electricity and heat – is a key element in calculating the likely effectiveness and expected ROI of renewable installations. Recently published research shows that solar thermal technology is more efficient than any other renewable system. According to the latest ...

  • What can you achieve with a solar system and battery?

    People often ask us about energy self-sufficiency. Just how hard is it to get to that point where you no longer have to pay a large corporation each time you turn on the kettle? This will depend on your usage patterns but for most people, a mix of renewable systems is the best option. We’ve taken a look at Gabriel’s home renewable systems as an example. Perhaps unsurprisingly, Gabriel ...

  • Offshore Wind Versus Solar in the Eastern US: An Unexpected Rivalry

    Less than a decade ago, offshore wind energy and solar PV were similarly priced energy sources. Unsubsidized installed costs for both exceeded $5 per watt, or more than double that for land-based wind. Despite their cost, both technologies were seen as the best hopes for supplying urban centers with green power, especially in the BOSNYWASH (Boston-New York-Washington, DC) corridor of the eastern ...

  • Solar fuels: how planes and cars could be powered by the sun

    Solar energy is the world’s most plentiful and ubiquitous energy source, and researchers around the world are pursuing ways to convert sunlight into a useful form. Most people are aware of solar photovoltaics that generate electricity and solar panels that produce hot water. But there is another thrust of solar research: turning sunlight into liquid fuels. Research in solar-derived liquid ...

  • Geothermal Energy Technologies

    Technology Overview   Nowhere is the raw power of geothermal resources more evident than at the Old Faithful geyser at Yellowstone National Park. (Joel Renner)  Geothermal energy is natural heat from the Earth's interior where temperatures reach greater than 7000°F. The heat is brought to the surface as steam or hot water—created when water flows through heated, permeable ...


  • Retrofit for the future project - funded by the technology strategy board

    A terraced house in Birmingham was refurbished with a target to cut heating bills by at least £1,000 a year and CO2 by 80%. The project aimed to address specific barriers to large scale low carbon housing retrofit. Measures to improve the energy efficiency of the house were carried out such as the application of exterior wall cladding and the installation of solar PV. Encraft will monitor ...

  • Grid Connection An open letter to those on grid considering pursuing hydro power

    Many people contact us concerning the possibility of using a power source that is either connected to the commercial power grid or feeding power to a house that is. While this may be possible, it is not likely to make economic sense. Over 99% of our customers are off-grid and there are reasons for this. The question is then more like: ’Can I put in a small hydro system or should I spend ...
