The technological innovation of solar cell module

Recently, the solar power system is relatively popular, many families and factories have been installed the system, which includes solar panels, battery modules, inverters, controllers, etc. The efficiency of the battery pack which is a very important part of the  system ,today let's have take a look at what the solar cell technology innovation.


According to Tigo Energy, a manufacturer of power optimizer module level, a string of energy output can be increased up to 20%, by using such a module-level power optimization program. However, a more realistic figure of 3% is recently reported in the United States, a 113 kilowatts systems using embedded with Tigo power optimization technology, Trina "Trinasmart" group commissioned cobalt supply.


By adding a module to the DC power optimizer, current and voltage output can be controlled so that the string current than by the shadow module damage. Further, by limiting the voltage, so that the module is allowed to output to the maximum power point, but less than the open circuit voltage, a plurality of modules can be safely connected to the same pv inverter. Through all the modules in the system for such power optimization, the net energy output can be significantly improved, especially for medium and large-scale photovoltaic systems.

At the module level integrated electronics can also make the module-level monitoring and individual modules, which can make the module more secure, and cost-effective maintenance remote disconnection of individual modules as needed. All of these electronics, including power optimization, which can be incorporated into the module junction box - making it easier for module manufacturers to adopt the technology.


The concept of embedded Optimizer is not new, and the first such intelligent modules using National Semiconductor's "The SolarMagic" technology being produced in 2010 GESOLAR. However, SolarEdge's technology has proven to be quite popular, now account for 70 percent of the global market component shipments. SolarEdge has also begun jointly with the panel manufacturer, with industry giants such as Yuhui Solar and LDK and other modular integration of the technology.


However, the advantage of module-level power optimization is not limited to these newer intelligent modules. For the system owner wants to redesign their systems or simply to maximize the power of their existing module, power-optimized electronics market may simply up to the existing standard module junction box - for example by SolarEdge courses.

In a significant development, PV module certification body, TÜV, announced a new certification process to assess the reliability of the intelligence module. The new certification test with the existing standards of reliability testing to produce a series of new test procedures, rigorous testing of AC and DC intelligent modules. Three or more different modules have been tested and certified rating agencies.



This importance of embedded power optimizers and the increasing availability of raised questions about its reliability and pressure standards and certification bodies, their current testing standards apply only to standard modules. In this regard, module manufacturers, and more importantly, the PV power plant operators have recognized the new certification process. If their recognition is any indicator, market growth seem positive affirmation intelligent modules.

Solar inverter efficiency is the key indicator

Solar inverter efficiency directly affects the entire solar system is a key indicator of the efficiency, the efficiency it is almost always a more important consideration for solar panels. You do not just have one inverter efficiency, it always works. All electric power generated by solar panels before you go through an inverter, you can use your home, or export to the grid, so the extra efficiency, each percentage, you can squeeze out of the inverse change will directly improve performance and return on investment of your solar system.

However, as you might expect, solar inverter manufacturers want their picture in the inverter absolute best light, so when they measure the efficiency, they make sure that all the conditions are in the laboratory apricot inverter efficiency absolutely perfect. As a result, you are unlikely to ever get quotes normative work efficiency in real life.

Develop any specific inverter efficiency, "real world", the easiest way is to take some hard work in both government laboratories in California and Europe who take it upon themselves to deal with the digital advantage for each the entire load, and an inverter in each of their respective markets, and the computational efficiency is a lot more realistic than the number of manufacturers.

If you want to get deeper into the solar inverter efficiency specifications of fun, you will be ecstatic to hear that my pleasure inverter has not yet begun the efficiency curve. This little-known inverter specifications can make or break the performance of your solar system.

Inverter ambient temperature - in the hot inverter obtained in lower efficiency drops. That is why it should always be installed in a cool, well-ventilated place.

DC voltage into the inverter from the solar panels. This gets pretty technical, so I will not cover here, but if you're a sadist, ask a salesperson what solar energy is that they are optimized, from the DC voltage of the panel, in order to maximize the inverter efficiency. Then step back and enjoy a long silence!

Impact than anything else, though your high efficiency inverter solar, more the big kahuna is the inverter load. Load of the inverter is another name for the power supply of the inverter as compared to the amount of its rated power. For example, a 1kW inverter running only 800W power inverter at 80% load.

When 33% of your system is running at full power, you will only run at maximum power inverter. Power does not drop very suitable for you to move along a curve to the left you see the efficiency of falling off a cliff. This can easily occur in the winter day, cloudy, etc.

So this is a good reason to be wary of PV companies trying to flog you a large inverter is far more than you need for the panel, the amount of your purchase! From the top curve to be from 30 to 70% of the power output, the curve is fairly constant at about 95% efficiency look.

You can build your own home solar panels

With the advances in solar technology, home solar power systems are becoming increasingly popular, in which to build your solar panels is a very important step for a solar power system, solar panel is a face.

Build a home solar panel following a few essential steps:

Step 1: Preparation of
Step 2: Create a solar panel house
Step 3: Add a solar cell together
Step 4: Position and fixed solar
Step 5: stamped seal your solar panels


The first thing you need to do is to collect all the material together, once you collect all the material, you can start building your solar panels.

Solar panels are a simple frame house, solar cells will hold. The bottom of the box with plywood and the sides are made of 3/4 "× 3/4" wood. Top box will plexiglass cover glass. If using a 3 "× 6" solar cell, splint will need to be cut in size to about 44 "× 21". This would fit two daughter boards 18 of each solar cell. 3/4 "wood should be cut to size, and add to the plywood with screws to create a border for the panel.

At this point, can be cut non-conductive backing and acrylic glass sizes as well. You should also paint the solar panel enclosure and UV protective backing material. Added to the cells together some of the most challenging project, but once you've done a few times, you'll see it is very easy to do.

To get started with this step, you should be solar cells in a non-conductive support, the front end down. Then, you can use a soldering iron, solder, rosin flux pen, and tabbing lines joining each row of cells connected in series.

Once all of the cells in each row are connected together, it is a time for each row into a non-conductive adhesive backing. This is the use of silicone gums. Terminal block before each line should stick to each other in the backing.
Once all the rows are fixed to the non-conductive backing, can be used to connect together the copper line. As with the cell, these lines should also be joining the series.

Front cover and seal the panel, you should test your panel with a voltage meter, and make sure everything is secure.
Once you have completed your test, you are ready to cover the solar panels of plexiglass enclosure, glass and seal it provides weather proofing.

As you can see, it is not so complicated to build your own solar panels. But you'll save time and money using proven methods. One of the most expensive components of DIY solar panels are solar cells. By using less expensive solar cell, can significantly reduce the cost of the panel.

Looking for cheap solar cells is the easiest place on e-bay. You may also be able to with your town highway department for damaged cells, the light from the roadside or local solar installation company checked and found a discount or free solar cells. But the best method of reducing the cost of their own so that a solar cell panel in accordance with a detailed guide. You can use, to successfully build your own solar panels on this page, but it takes some trial and error, to spend your time and money.
