    Solar Energy Power Generation: Introduction

    Sky Resources Solar Technology Co., LTD ----projects Management Training document

    Clarification of the Solar Energy Power Generating
    Following two type of the solar energy power generating
    Grid-off solar energy power generating
    Main used in the area where is no electricity supply or the telecommunication station which is faraway from the electricity net or the wireless places.
    Key components:solar panel、battery、intelligent controller、inverter 、electricity distribution and anti-lighting system. (electricity distribution is close to the active load).
    Advantages:offer the independent electricity net which will not restricted by the local public electricity net.
    Disadvantages:much waste of the energy resources or can controller the use of the solar energy resources. the electricity use is high restricted by the weather condition, the low efficiency of use and high investment, a little low system life span (especially say the batter’s life span).
    Grid-On PV System
    Main use in the place where the city electricity distribution net. It is the lead direction of New energy from home and all over the world.
    Key components: solar panel、grid-on inverter、 electricity distribution and
    anti-lighting system (much simple ).
    Advantages:high efficient use of the system,long life span;the investment cost is some lower;the use of the electricity will not restricted by the system itself and the weather condition influence.

    The Independent Grid-off Solar Energy Power Generating System Detailed Introduction
    Solar Panel/Module
    Solar Panel is a generating equipment which can transfer the solar light energy to the DC electricity energy. It is made as a single panel when use according to the different requirements on the power output and its voltage. It also can be used as several solar panel connected in series (which is to meet the demands on voltage) and connected in parallel (which is to meet the demands on current). this way can make as the panel/modules arrays to supply much higher electricity demands. the solar panel/modules has many advantages such as high power efficiency on area,long life span, and high reliability,during the use period, the loss of the output power is less than 20%.
    The structure of the silicon solar panel/ module
    The features of Volt-Ampere for PV solar panel
    Generally speaking,the solar panel electricity generating is increased in percentage with the intensity of the sunlight. With the surface temperature increased of the solar panel slightly decreased.
    The so-called general of the solar panels that power is in the sunlight intensity of 1000 W/M2, components, surface temperature is 20 ℃, Imax * Umax value.
    Photovoltaic module installation angle
    Photovoltaic module installed inclination should be guaranteed to receive the maximum sunlight exposure, in normal circumstances components and the horizontal direction for the local latitude ± 5 °to 10 °. That is, when the reduction in the summer, when the increase in the winter. If a fixed angle brackets, the use of local latitude tilt angle. For example, the city of Shantou to 23.42 °latitude.
    Battery discharge curves
    10 hour rate (0.1 CA), 5 hour rate (0.17 CA), 3 hours rate (0.25 CA) discharge termination voltage: 10.8 V /set; 1 hour rate (0.55 CA) discharge termination voltage: 10.5 V / set
    Termination of battery discharge voltage minimum not more than 9.6 V / only to ensure that the battery will not over-discharge.
    the relationship between Battery life and temperature curve
    In the environmental temperature 15 to 25 ℃ and the proper use of circumstances, the use of rechargeable batteries floating design life of 5 to 8 years. Environmental temperature on the battery life is greatly affected when the ambient temperature every 10 ℃ increased battery life of about 50 % reduction. Therefore, to extend battery life, the...
