with the growing shortage of energy, pollution is serious, the environmental protection consciousness of people are increasing, photovoltaic power generation into the homes is something sooner or later. Although the photovoltaic (pv) is a high-tech, just like the original our computer always find someone else to install, and now the book is installed, the installation of photovoltaic equipment in the future will surely become one of our common sense. Solar panels, industry also called components, photovoltaic power generation is the main equipment. Components usually have three types of thin film components, monocrystalline, polycrystalline component, whether a large desert plant or distributed small system, at present basically polycrystalline world ( This is the result of recent years polycrystalline cost reduction and improving the efficiency of polycrystalline) 。 Components from top to bottom in turn by the pervious to light glass, batteries, aluminum back of cascading aluminium frame to be fixed. We must first understand the components for newly purchased component five basic parameters: the peak power ( Pmax) , peak voltage ( Vmpp） , peak current ( Isc） , open circuit voltage ( Voc） , short circuit current ( Isc） 。 These are the standard state conditions ( Atmospheric quality AM = 1. 5, the temperature is 25 ℃, the light intensity 1000 w/m2) Were measured, the test values, so our voltage and power and nominal value is not consistent. We know that the power can be got by voltage and current of flight. Component has a feature is power as the voltage increased first and then to zero, that is to say, the component has a maximum power point, this power point is the peak power, the corresponding peak voltage is the voltage, the corresponding current is the peak current, also is the numerical components labelled. When the open circuit voltage when the component when what all don't pick on both ends of the positive and negative electrode voltage, short circuit current will is together of the cathode is current. In the distribution system, the first to see how much is the sum of our power of electrical equipment, using electricity power divided by monolithic component power can work out how much we need to block components. In front of the parallel of components, we should also know that the component is the supply of power battery, together to get the voltage (we need Components, there are many small cells, and they are together) In parallel, up less than the maximum current of the equipment work.
