The Blessings from the Sun

Sun Light, Solar Heat, Air Heat
Living with zero utility costs and zero CO2 emissions,
utilizing three types of natural energy

In order to utilize solar energy effectively, SANYO Homes advocates the use of solar energy generating systems with the world’s highest efficiency power generation and also solar hot water supply systems which boil water by solar heat in the daytime and by supplied heat from the air at night. We name the proposal of living with zero CO2 emissions and zero utility costs as “The Blessings from the Sun.”
  • The amount of solar energy per hour falling on earth : 127 trillion kW/hr
  • The energy consumption per year in the world : 93 trillion kW (Equivalent oil conversion about 8 billion tons)

    The features of “The Blessings from the Sun” utilizing three types of natural energy
    Creating the world’s leading cell conversion efficiency
    In comparison between SANYO’s HIT solar cells and other cells of normal poly-silicon, the energy conversion efficiency of the SANYO’s solar cells are the world best at 18.9% and provides 20-40% more efficiency than other producers. It is about 100 dollars less expensive for an annual estimated amount of power generation.
    Equipped with a high efficiency heat collecting panel
    Hot water, collected efficiently by the solar heat collecting system is 70 degrees C maximum in summer. In winter, it is possible to provide hot water at 40 degree C maximum.
    * On a rainy or cloudy day it cannot be expected to harness solar heat.
    Utilizing Air Heat Effectively
    Achieving energy saving with the hot water storage units, by utilizing heat from the solar heat collecting system, the heat pump unit and the heat energy obtained from hot water collected from a bathtub.
