Tips of design BIPV

What is BIPV?

BIPV meaning:Building Integrated Photovoltaics .

It means that they are built/constructed along with an object. They are also planned together with the object. Yet, they could be built later on. Due to specific task cooperation of many different experts, such as architects, civil engineers and PV system designers, is necessary.

First, the mechanical properties of solar panel

As a common PV modules, as long as the detection by IEC61215, to meet the anti-130km / h (2,400 Pa) pressure and resistance to 25mm diameter hail 23m / s impact requirements. Used as wall panels and roof panels of photovoltaic lighting component, not only to meet the performance requirements of PV modules, while three of the walls to meet the test requirements and building safety requirements, requiring higher mechanical properties and structure of different ways. For example, size 1200mm × 530mm common PV modules generally use 3.2mm thick steel plus aluminum frame ultra-clear glass can be achieved using the requirements. However, the components of the same size used in BIPV buildings, in different locations, different floor height, and the types of installation, it asked for the mechanical properties of glass may be completely different. CSG circulating outside the building components used in double wall is two 6mm thick steel made of ultra-white glass, laminated PV modules, which is calculated through a rigorous mechanical results.

Second, the building is an art
The first is a BIPV building construction, it is the architect of the art, the music equivalent of musicians, painters of a famous painting, and for the buildings, the light is his soul, thus demanding the building of light and shadow. But the common PV modules are mostly used for Gyrosigma ultra-white glass tempered glass, frosted glass block line of sight with its Gyrosigma role. If the BIPV components are installed in the building of the tourist office, this position requires light transparent, then we should use double-sided glossy production of ultra-white glass, tempered glass components, used to meet the building’s function. Meanwhile, in order to save costs, the back of the glass panels can be smooth with ordinary glass. A building is the key point is the appearance of the building effect, sometimes subtle lack of coordination can not be tolerated. But the common PV module junction box generally stick to the back panels, junction boxes larger, it is easy to destroy a sense of the overall coordination of the building is not usually acceptable for architects, so BIPV building junction box eliminates the need or request hidden, then the bypass diode junction box without protection, to consider other ways to protect it, you need to bypass diodes and cables hidden in the wall structure. Bypass diodes on the wall such as the skeleton structure, to prevent direct sunlight and rain. Common PV modules generally exposed in the component cable below, BIPV building the cable requirements of photovoltaic components all hidden in the wall structure.

Third, the building structure and electrical properties of PV modules with
In the design of BIPV panels to consider when building their own voltage and current of photovoltaic system equipment selection, convenience, but the building’s facade may be a number of sizes, geometric forms of varying composition between the components that will cause voltage and current is different this time can be considered to partition the building facade and adjusting grid, BIPV components close to the standard components to make electrical properties can also be used in solar cells of different sizes to meet the requirements of sub-grid to the maximum Limit results to meet the building facade. Also, you can corner on a small number of cells are not connected into the circuit to meet the electrical requirements.

Fourth, clever use of solar energy in the building
Solar energy for the protection of the environment has created favorable conditions, so many architects exploit the use of solar energy construction of solar buildings.

1, solar wall: The United States invented the solar wall construction experts, is installed in the building of the wall outside the black hole a thin layer of aluminum, the wall can absorb the radiation to 80% on solar energy. The air is sucked into preheated aluminum plate, pumped through the wall inside the building, which can save the energy consumption of central air conditioning.

2, solar window: two German scientists invented windows with light and heat regulation. One is the solar temperature control system, the surface of the window during the day and capture the building heating, and then passed to the solar wall and floor space for storage, at night it came alive again; the other is automatically adjusted the amount of sunlight entering the room, the same as the color sunglasses, according to the room temperature setting, windows or become transparent or become opaque.

3, Solar Housing: German architect plug more. Horizon Hills built a track in the sun on the base of the solar rotation housing. The housing is installed on a disk base, driven by a small group of solar electric motor gear, the Housing Foundation in the circular orbit to 3 cm per minute, the speed of rotation with the sun. The system tracks the sun’s power consumption is only the power house solar power 1%, and the room generally can not solar power is equivalent to twice the rotation of the solar house.

Fifth, the latest policy BIPV
1, the solar PV building applications for financial assistance fund Interim Measures (Ministry of Finance, the Ministry of Housing and Urban Construction March 26, 2009 issued)
2, building on support for accelerating the application of solar photovoltaic policy interpretation (Finance Construction [2009] No. 128, Ministry of Finance in April 2009 release)

Tips of Testing Solar Panel

Most in the most people that need to set up solar panels at the roof of the properties consider that all they must do is set up them, however they overlook about assessment them after which if a little something won’t perform adequately they must phone for that installers once again and using this method they reduce time and get stressed.
Solar panel assessment pertains to employing an amp meter at the panel. power is acknowledged for being measured in amperes. This factor may be accomplished with an amp meter. this kind of a equipment are heading to be connected towards bad and good terminals at the solar panel after which the panel are heading to be subjected towards sunlight. In purchase to guard by yourself from injuries and protected the amp meter from any destruction you really should 1st price the meter greater compared to solar panel is. The amp meter will present you on its display ‘the brief circuit current’. This are heading to be the level of electric present-day that 1 could assume out of your panels to give. OF program everything is established by how powerful was the sunshine so it can be indicted to conduct your solar panel assessment when there is ordinarily a complete sunshine outside.

Besides employing an amp meter you’ll be in a position to decide the energy yield of your respective solar panel by employing an additional strategy that implies measuring the resistor’s voltage. because of this solar panel assessment process you’ll require a electronic multi-meter (that actions the DC voltage) and numerous resistors. subsequent to acquiring every one among the essential measurements you’ll be in a position to use this formulation for calculating the energy output: present-day equals Voltage / Resistance. subsequent to that 1 could constitute a overall performance graphic by plotting the energy output.

You really should also be mindful that a solar panel will transform the sunshine into DC (direct current) energy not AC energy as some may perhaps expect. it is why you require for that solar panel assessment methods a DC electronic multi-meter.

Watts are heading to be applied for measuring the energy the fact that solar panel produced for charging electric batteries as an example or for employing dwelling appliances. The formulation for calculating the energy is energy equals Voltage*Current. All you’ve still left to perform is continually to measure the amperage and voltage of your respective solar panel and plug the info to the equation. using this method you’ll know precisely when the solar panel are heading to be in a placement to include every one among the power you desired it to supply you once you made a decision to set up this kind of a factor on your own roof.

You will even use a solar cost controller that could be designed for regulating the energy that could be brought through the solar panel towards rechargeable batteries. this kind of a controller has the intent of by-passing eventual overcharges also to present a very good power supply cost based at the temperatures outside. apart from solar panel assessment you really should also analyze the very well working of the cost controller.

If you consider you’ll be in a position to not conduct the solar panel assessment on your personal or you do not have time for that phone some panel installers and request them to perform this to match your needs because it may perhaps conserve you from numerous difficulty later on on.

What is a solar inverter?

What is a solar inverter?

AC solar inverter for solar generation system: solar panels, charge controller, inverter and battery together form the inverter is a power conversion device, inspired by the inverter can be divided into self-excited oscillation inverter And he excited oscillation inverter.

AC power generation system of solar energy panels by the sun, charge controllers, inverters and batteries together form; solar solar inverter.Do not include inverter DC power system. Inverter is a power conversion device, inspired by the inverter can be divided into self-excited oscillation inverter and his excited oscillation inverter. Main function is to reverse the battery’s DC into AC. Through the full bridge circuit, generally modulated SPWM processor, filter, boost, etc., are with the lighting load frequency, rated voltage AC sine match for the system end-users. With inverters, you can use DC battery to provide AC electrical appliances.

Type of Solar inverter

Centralized Solar Inverter

10kW) systems, many parallel PV strings are connected to the same concentration of the inverter DC input terminal, the general use of large power IGBT three phase power photovoltaic inverter power stations (> 10kW) systems, many parallel PV strings are connected to the same concentration of the inverter DC input terminal, the general use of large power IGBT three phase power module, the use of smaller power field effect transistors, while the controller using the DSP to improve the conversion quality of the output power, making it very close to the sine wave current. Most important feature is the system’s power and low cost. But by the PV group and part of the string matching the impact of shading, resulting in the entire PV system efficiency and power capacity. At the same time the reliability of the photovoltaic power generation system of photovoltaic cells by a group of poor working conditions. The latest research is to use space vector modulation control, and the development of new inverter topology connections to get the high partial load efficiency of the case. In SolarMax (Shohreh Mike) to focus on the inverter, can be attached to a photovoltaic array interface box, for each string of a string of photovoltaic panels to monitor, such as a set of strings which is not working properly, the system will This information reached the remote controller, this can be addressed through a bunch of remote control to stop working, which will not be a string of failures and reduce the PV strings and influence the work of the entire photovoltaic system and energy output.

Group string Solar Inverter
Group of string inverters have become the international market is now the most popular inverter. Group string inverter is based on the concept based on modular, each PV strings (1kW-5kW) through an inverter, the DC side has a maximum peak power tracking in parallel and in the exchange of side-grid solar inverter schematic diagram
. Many large-scale photovoltaic power plants group string inverter. Advantage of differences from strings between the module and shading effects, while reducing the optimal operating point of PV modules and inverter mismatch, thereby increasing the generating capacity. These technical advantages of the system not only reduces costs, increases system reliability. Meanwhile, the group introduced between strings “master – slave” concept, making a single string of energy in the system can not make the work of a single inverter case, several groups of PV group strung together, so that one or a few work to produce more power. The concept of the latest of several between the inverter to form a “team” instead of “master – slave” concept, making the reliability of the system one step further. Currently, no string inverter transformer group accounted for a dominant position.

Multiple string Solar Inverter
Multiple string inverters are set to take a centralized inverter and the advantages of string inverters, to avoid its shortcomings, can be applied to a few kilowatts of photovoltaic power stations. In the multiple string inverters, including the peak power of different single track and DC to DC converter, the DC to DC through a regular exchange of the inverter into alternating current electricity grid to the Internet. PV strings of different ratings (for example: different power ratings, each string of the number of different components, different component manufacturers, etc.), different sizes or different technology, photovoltaic modules, in different directions strings (such as: East, South and West), a different angle or shading, can be connected in a common inverter, the same string of each group are working in their respective peak on maximum power. At the same time, reduce the length of the DC cable, will cover between strings and the shadow of differences between strings minimize losses caused.

Component Solar Inverter
Inverter is the component of each PV module is connected with an inverter, and each component has a single maximum peak power tracking, so that the component and inverter with better. Typically used for 50W to 400W photovoltaic power stations, the total efficiency is lower than group string inverter. Because it is paralleled in the exchange, which increased the exchange of the complexity of the connection side, difficult to maintain. Need to be addressed is how the other more effective and power grid, the simple way is directly through the common AC outlet to the grid, so that you can reduce the cost and installation of equipment, but often the safety standards throughout the network may not allow doing so, the power company generating devices may be directly opposed to the average home user connected to the common outlet. Another and security-related factor is the need to use isolation transformers (high or low), or allows the use of non-transformer type inverter. The inverter in the most widely used in glass curtain wall.
The efficiency of the Solar Inverter
The efficiency of solar power inverter that due to the demand for renewable energy, solar inverter (inverter photovoltaic) market is growing. These inverters require high efficiency and reliability. These inverter circuits used in power were investigated, and recommended switching and rectifier for the best choice. The general structure of optical inverter shown in Figure 1, there are three different inverters available. Sunlight through the solar modules connected in series, each module contains a set of tandem solar cells (Solar Cell) unit. Solar modules generate DC (DC) voltage of several hundred volts in magnitude, the values are based on an array of light modules, the battery temperature and the number of modules in series may be.

The primary function of this type of inverter is the input DC voltage is converted to a stable value. This feature is achieved through the boost converter, and the need to boost switch and boost diode. In the first structure, the boost stage is followed by a full-bridge isolated converter. Full-bridge transformer is to provide isolation. Output on the second full-bridge converter is used to from the first-class full-bridge DC-DC converter converted into AC (AC) voltage. The output then by an additional two-contact relay switch connected to the AC power network before being filtered, the aim is to provide a safe event fault isolation and quarantine during the night and the power grid. The second structure of a non-isolated solutions. One, AC AC voltage from the boost stage output DC voltage directly. The third structure, using the power switch and power diode innovative topology, the step-up and the AC part of the functional integration of the exchange have a special topology in spite of the conversion efficiency of solar panels is very low, so that the efficiency of the inverter as possible close to 100% is very important. In Germany, installed in the south-facing roof 3kW series estimated annual power generation module 2550 kWh. If the inverter efficiency from 95% to 96%, more than a year can generate electricity 25kWh. The solar modules with additional cost of generating this 25kWh an inverter with a considerable increase. The efficiency from 95% to 96% will not be doubled so that the cost of the inverter, so the inverter is more efficient to invest in is the inevitable choice. The emerging design, the most cost-effective to improve the inverter efficiency is the key design criteria. As for the reliability and cost of the inverter are two other design criteria. Higher efficiency can reduce the load cycle temperature fluctuations, thereby enhancing the reliability, therefore, these guidelines are actually associated. The use of the module will also improve reliability.

Solar Cell Introduce

A large number of products currently on the market of single crystal and polycrystalline silicon solar cell (what is solar cell?)efficiency of about 15% of the average up and down, that is, such a solar cell can only convert the incident solar energy 15% of available power, and the remaining 85% of waste into useless heat. Strictly speaking, the present solar cells, but also some type of “waste of energy.” Of course, theoretically, as long as the solar cells can effectively inhibit the carrier and phonon energy exchange, in other words, the effective suppression of carrier band or band between the energy release, can effectively prevent unwanted solar cells heat generation, greatly improving the efficiency of solar cells, even to the ultra-efficient operation. The idea of such a simple theory, in practice the technology, but can use different methods to implement this principle. Ultra-high efficiency solar cells (third-generation solar cell) technology development, in addition to the use of innovative design elements, to try to break their physical limitations may also be due to the introduction of new materials, and to achieve a substantial increase in conversion efficiency.

Thin film solar cells, including amorphous silicon solar cells, CdTe and CIGS (copper indium gallium selenide) cells. Although the number of producing multi-film solar cells with conversion efficiency of crystalline silicon solar cells are still unable to compete, but its low manufacturing costs are still to have a place in the market and future market share will continue to grow.

Photosensitive dye solar cells (Dye-sensitized solar cell, DSSC) is a recently developed a new type of solar cells. DSsC also known as the Grätzel cell, because in 1991, published by Grätzel et al and the general structure of different photovoltaic cells, the substrate is usually glass, it can be transparent and flexible polymer foil (polymer foil ), glass with a layer of transparent conductive oxide (transparent conducting oxide, TCO) is often used FTO (SnO2: F), and then having about 10 micron thick layer of porous nano-sized TiO2 particles (about 10 ~ 20 nm) the formation of a nano-porous film. And then coated with a layer of dye attached to the TiO2 particles. Dyes are usually used ruthenium polypyridyl complex. In addition to the upper electrode is the use of glass and TCO, but also coated with a layer of platinum catalyst for the reaction when the electrolyte, the second floor between the electrodes, the injection fill containing iodide / triiodide electrolyte. Although the highest conversion efficiency of DSC cells about 12% (theoretical maximum 29%), but the manufacturing process is simple, it is generally considered to significantly reduce production costs, while reducing the tariff per unit of electricity.

Tandem-type battery
Tandem-type cells (Tandem Cell) is a novel use of the original structure of the battery, through the energy gap by the design of different layers to achieve the absorption efficiency of solar cells optimized structure design. At present we know from theoretical calculations, if more layers in the structure into the number of batteries, the battery efficiency will be increased gradually, even up to 50% conversion efficiency.
Edit this paragraph and transparent 5″ monocrystalline Silicon 5 inch 125 Series Solar Cell

Organizational networks, according to recent reports, American physicist, the U.S. Department of Energy’s Brookhaven National Laboratory and Los Alamos National Laboratory scientists have developed a light can be absorbed and transformed into electrical energy of its large area of new transparent film . The film semiconductor and fullerene as raw materials, with a micro-cellular structure. Research published in the latest issue of “Materials Chemistry” magazine, the paper said the technology can be used to develop transparent solar panels can even use this material to generate electricity in the windows. The material from the semiconductor doped polymer composition of carbon fullerenes. Under strictly controlled conditions, the material can be self-assembled by a micron-scale hexagonal structure expands to the size of a few millimeters of the surface covered with micro-honeycomb structure.

Responsible for the research Brookhaven National Laboratory, Center for Multifunctional Nanomaterials physical chemist Mircea Cartwright said that although the production of such honeycomb film with the traditional use of polymer materials (such as polystyrene) similar process, but the semiconductor and fullerene as raw materials, and allow it to absorb the light generated charge is the first time. According to reports, the reason why the material can be transparent in appearance only because the polymer chains are closely linked with the edges of hexagons, while the remaining part of the structure is relatively simple to connect the points as the center outward thinner. This structure has a connection function, also has a strong ability to absorb light, but also conducive to conduction current, while other parts of the relatively thin and more transparent, since the main role of light.

Researchers through a very unique way to weave this honeycomb films: First, fullerene containing polymers and added to the solution, including micro-scale thin layer of water droplets. These water droplets in the polymer after exposure to self-assemble into large arrays will, and when the solvent completely evaporated, it will form a large area of hexagonal honeycomb plane. In addition, the researchers found that the formation of the polymer and solvent evaporation rate is closely related to the corresponding materials will determine the final charge transfer rate. Slower solvent evaporation, the more compact polymer structure, charge transfer rate is the sooner.

“This is a significant low-cost and effective preparation method has potential applications from the laboratory to large-scale commercial production being.” Cartwright said.

By scanning electron microscopy and fluorescent probe confocal scanning microscope, the researchers confirmed that the new material uniformity of cellular structure and its different parts (edge, center, node) of the optical properties and charge generation conditions were tested.

Cartwright said: “Our work on the cellular structure so that people have a deeper understanding of the optical characteristics. The next step we plan to apply this material transparent and flexible 6″ Polycrystalline Silicon 6 inch 156 Series Solar Cell and curled the manufacture of other devices which, in order to promote this kinds of cellular membrane into the practical stage as soon as possible. “
