Photovoltaic modules, roof area and what is the relationship between the installed capacity

Photovoltaic power station by the tile ( W) To calculate, tile is installed capacity, not according to the calculated area. But the capacity has something to do with area is also. Because now in the market of photovoltaic power generation in three kinds: 1. Amorphous silicon photovoltaic components; 2. Polycrystalline

photovoltaic (pv) power is the watt ( W) Calculation, watt is installed capacity, rather than area. However, the installed capacity is related to the area. Because there are three kinds of photovoltaic power generation on the market: 1. Amorphous silicon photovoltaic module; 2. Polycrystalline silicon pv module; 3. Monocrystalline silicon photovoltaic component is a core component in a photovoltaic power generation. Amorphous silicon pv module maximum power is 78 w per square meter, minimum power is only about 50 w. Features: covers an area of big, fragile, conversion efficiency is low, not safe transportation, attenuation is fast, but the characteristic of weak light. Below: now the polycrystalline pv module for 250 watts per square meter, 255 w, 260 w and 265 w, this is very common in the market. Features: slow recessing and long service life, better than that of single crystal silicon photovoltaic component prices. It is also one of the more popular on the market. Below: monocrystalline silicon photovoltaic modules market commonly used for 260 watts, 265 watts, 270 watts, 275 tile, covers an area of about 1. 63 square meters. Features: conversion efficiency with area of polysilicon, slightly higher than the cost must be higher than that of polycrystalline silicon photovoltaic modules. Its service life and polycrystalline silicon photovoltaic modules are basically the same. Below: after some analysis, we should understand the size of various kinds of photovoltaic modules. However, the installed capacity is closely related with roof area. If you want to calculate how much your roof can be installed the system, you must first understand your roof belongs to the type. Photovoltaic roof type in general there are three kinds of roof, color steel roof, brick and concrete flat roof. Different roof has different installation methods to the photovoltaic power station, installation of the plant area is also different. Caigang watts roof photovoltaic power station installed on the top of steel structure caigang WaWu. Usually, the pv modules installed only at the king's south side. Laying a ratio of 1 kw, take up little 10 square meters. That is to say, a 1 mw ( 1 mw = 1000 kw) Project need 10000 square meters of area. Brick roof when install photovoltaic power station in the tile roof, pv modules are usually at 08:00 and 16:00 between laying on the roof of uncovered area. Though different methods and color steel roof installation, laid similar proportions, 1 kw, covering an area of about 10 square meters. The flat concrete roof photovoltaic power station installed on the flat roof. In order to ensure that the component receive as much sunlight, it is necessary to design the best horizontal Angle. Between each component needs certain interval, therefore, to ensure that they won't be in front of the component. Therefore, the whole project takes up the roof of the area will be greater than caigang watts and villa roof tile components. Planning home decoration is not cost-effective, can be installed? At present, photovoltaic power generation project has been the support state, and the corresponding policies, every generation 0. 42 yuan, the issue of subsidies for 20 years. There may also have different places. Please consult the local power bureau specific subsidies. So long as has the property of buildings or structures can be installed, the application does not require any fees.
