Make your solar photovoltaic system perfect

Good customer relations, is an important factor to consider when choosing your solar installation. Decided to install solar PV panels can be excited by a number of factors. Whether you've had enough of the six, who are increasing their prices continue to want a little stability or decisions, interest rates, such as those from the bank yet, everyone has their own reasons to come from solar energy. In most cases, this is considerably less mixing motivation.

The combination of general importance varies from one person with a specific driver to vary greatly. Some people will have a higher priority than self-sufficient financial returns, for example. In view of this, it still surprises me that people are ready to sell PV systems without installing truly consider their own personal values and drivers. This method allows you to select a couple of boxes can system, but not very full package.

A good installation company will have access to a variety of panels and solar inverter efficiency , allowing them to customize the system to meet your specific needs. The company is not dependent on a particular vendor can provide different panels and / or inverter for different scenes.

The panel can be used efficiently, in which the roof space is limited, and the total system profit is important. The payback period is short, the most good by the panel has a lower initial cost of implementation. Although all of the panel must meet very strict environmental standards, as well as those who go above and beyond by using recycled silicon, which may be suitable for people whose main purpose is to green.

When all of the systems and prices are at its time to decipher information. This can be confusing, because you may have a variety of different devices and digital work through. My recommendation here is to use a surveyor as a resource. Ask them to criticize their competitors. An experienced surveyor should be able to highlight important differences between them.

Often means more expensive and more comprehensive; if a company's price can be higher, because there are a lot of hidden value of their products in. Structural surveys, detailed custom system design, project management team, comprehensive after-sales service is often overlooked, but unfortunately most obvious in their absence.

If a company's price is higher than others, tell them! Speaking they can explore their system or blank some hidden advantages, in others, you may not have considered this proposal. Do not be afraid to discuss what you like and do not like to recommend contact with each other within the company's. If you need the flexibility there may be some flexibility on price; by the end of line stock or install in a short time can sometimes lead to lower prices. Also, be wary of special offers and discounts, designed to give you rush into an agreement did not put some real research. Remember; cheap is that you have only one benefit.

Once you have chosen your list, you should ask to visit the site offer businesses a comprehensive and thorough investigation. I often hear companies quoted on the phone, using Google Earth or similar price work. This is fine, a rough estimate, but it should not be used in the final price. There are so many unknowns, with a system that determines when the only site visits, all of which will have a bearing on the cost, performance, and return on investment in order to restore the system. Mechanic can not give you an accurate price to fix your car, just look at pictures of it, neither can the price of PV system designer inaccurate site investigation.

How to convert solar energy from solar panels into usable energy

Solar companies often focus on design is also a source of solar energy equipment related to businesses and households. Solar Gadgets Solar who are most likely to be an effective means for yourself, try to reduce spending. Solar panels to reduce the amount of energy used to heat water and your family. Although the use of solar panels and cut off your power prices down, they are not cheap, it may take several years to recover the cost of reducing energy costs.

Solar harm ecosystems entails much smaller and lower prices, contrary to the use of electricity and non-renewable fuels burned to provide energy for our daily lives.

Solar energy is sustainable, non-polluting, widely available, anyone who does not have, in any country, for free! It can be directly used for heating the air, thus providing heat buildings; this work in a similar manner to the greenhouse. Instead, heat transfer to heat water central heating or washing, and may be accumulated by the solar panel to.

Solar energy is not available at night, making energy storage an important issue, in order to provide continuous availability of energy. Two wind power and solar power generation is irregular energy, which means it can be used where it can be used when all the available outputs, must be taken if it is available, either stored or transported in the transmission line.


Solar energy can be stored in a high-temperature molten salt. Two such use solar energy storage, so that it is capable of storing 4460; TJ m ^ tank, sufficient to provide a complete output about 99% efficiency.

A green, clean and national energy given by solar technology. Solar can even be used to meet our power needs. Solar power is becoming the leading edge of alternative energy sources. Solar companies are increasingly being built international. The reason? For we can not independently associated with old age are not energy gases, such as the reasons for fossil fuels, oil and timber to meet each of our growing energy needs.

Development of new technology can improve the efficiency of solar inverters

The inverter is silent workhorses conversion power, such as solar panels and batteries into usable power supplies. There is a solar cell panel around the pv inverter considerable innovation in recent years, due to a number of solar roofs have begun to move from a single large central inverter to be embedded into a smaller on each panel "micro-inverters." 

Now a year and a half old chip startup Empower Microsystems has been pushing even farther, solar inverter innovation and development of a new low-voltage solar micro-inverter based on its new chip design, it said lower cost, more reliable than those currently on the market efficiency.

Bonanno is a disruptive force very confident inverter technology, known as "universal micro inverters." He believes that it can "replace all solar inverter options, hands down." The key technology of the inverter is on how the chip synchronization, and control power flow in low voltage, and an inverter box design itself.

The company's inverter technology can be connected to a solar panel system, rack or frame, or embedded in a single solar module level. Bonanno said the inverter 5 times more reliable than 5% of high efficiency and cost than traditional "string" inverter, has been used dozens of young and 20%. The potential for lower cost inverter, the entire cost of the solar system may be lower, in addition to the price of solar modules in the recent decline.

Energy storage technology using micro-inverters, solar panels from temporary storage of the DC power supply and AC mains decoupling of. In Empower micro inverter system with a new generation of solid capacitors, this energy storage technology, while other systems are more often used more conventional liquid-filled electrolytic capacitors.

There are a lot of competition in the solar inverter space. Not only have the new micro-inverter companies, such as Enphase Energy Company, and optimization techniques and Tigo Energy's power supply from the same edge of the sun, and it is the same as the traditional SMA inverters giants dominate the market.

The plans to empower micro systems are actually more daring than just replacing the solar inverter. This technique can be applied to energy storage and electric vehicles, as well as Bonanno said the day, they want to enter these markets, but also the road.

Something important about pv power system

Photovoltaic panels convert light energy from solar cells directly into DC power. The word "photovoltaic" comes from the word "photo", meaning light, "V", from Alessandro Volta, a pioneer in the study of electricity. Therefore, the "photovoltaic" literally means "light - electricity."

"Off-grid" or independent, solar photovoltaic system is not connected to the grid, and often rely on battery storage power generated by the solar system. "Grid" solar photovoltaic systems connected to the grid, allowing you to use electricity at night or when the sun do not shine. When your solar panels produce more electricity than you use, the electricity can flow back into the grid, if you have an active program of net metering program. This allows you to rotate the credit meter backwards.

Structure and working principle of photovoltaic inverters

The inverter is mainly composed of switching elements such as transistors, so that by regularly repeated switching elements - off, the DC input to AC output. Of course, this is simply a solar inverter wholesale output waveform generated by the circuit on and off is not practical. Generally require the use of high-frequency pulse width modulation, so close to the sine wave voltage across the width becomes narrow, the center of the sine wave voltage of wider width, and in a half-cycle so that the switching element is always in one direction at a certain frequency operation, so that the formation of a pulse wave columns. Then let the pulse forming a simple sine wave filters.

The inverter is a power adjustment device consisting of a semiconductor device, is mainly used to convert the DC power into AC power. Generally consists of a boost circuit and an inverter bridge circuit. Boosting circuit boosting the DC voltage of the solar cell to the inverter output control required DC voltage; DC voltage of the inverter bridge circuit put boosted equivalently converted into a common frequency AC voltage.




Hybrid Inverter



AC inverter only has direct conversion function, it also has to maximize the performance of the solar cell functions and system fault protection. Summed up automatically run and stop function, the maximum power tracking control, anti-run single function, automatic voltage adjustment, DC detection, DC ground detection. Here a brief self-running and stop function and maximum power tracking control.


Hybrid Inverter


Omnik has launched new single phase inverters,Omniksol-2k-TL series inverters use world class technologies, the maximum convert efficiency could reach 97.5%, MPPT adaptation efficiency is high up to 99.9%, and Omniksol-2k-TL Photon Efficiency No.1 up to 3k in the world.



Hybrid Inverter


The morning after sunrise, solar radiation intensity gradually increased, the output of solar cells also increased, when the work required to achieve the output power of the inverter, the inverter automatically starts running. After entering operation, the inverter output will always monitors the solar cell module, as long as the required output power of the solar cell module is greater than the output power of inverter operation, the Hybrid Inverter will continue to run until sunset shutdown, even rainy days The inverter can also run. When the output of solar modules become smaller, the inverter output close to 0:00, the inverter will form a standby state.




Hybrid Inverter



The output of the solar cell module is vary with the intensity of solar radiation and temperature of the solar cell module itself. In addition, as the solar cell module having a voltage drop with the increase of the current characteristics, so there can be obtain the optimum operating point of maximum power. Solar radiation intensity is changing, apparently optimal operating point is changing. In contrast to these changes, and always let the operating point of solar modules at maximum power point, the system always get the maximum power output from the solar module, this control is the maximum power tracking control. Most important feature of solar power inverter system is included with the maximum power point tracking this feature.

The price and advantages of solar pv system

Just with any product, the age old saying “you get what you pay for” is relevant to energy systems. Let’s slice a PV system to better understand the cost difference. Whether you lease or purchase a solar system  you may find yourself asking, “Why does this system cost more than that system?” “Is this installer overpriced?” It could be a matter of installation price, but more than likely the cost difference is in the components.


 high efficiency inverter solar 






Now,lets see the advantages of the solar pv systems:

Solar Modules were compared at the Photon Laboratory in Germany. The benchmark for the yield measurement is based on the number of kilowatt-hours produced by the front side of a module. Not all panels are equally capable of collecting the same amount of energy.

While the performance ratio is the decisive criterion for the technical quality of a solar module, technology alone is not the only measurement. Long-term stability is equally significant for a product that needs to function well for at least 20 years. Panels that offer durability come with longer warranties.

Proper racking provides a support for modules to ensure proper installation. A good racking system aligns solar modules evenly; creating a flush, clean line. Flashings for roof penetrations and wire management are extremely important for long lasting, worry free performance of PV systems Inverters

Micro-inverters attach to each solar panel and therefor make array expansion easy. Inverters that convert power for an entire array limit expansion of the system. Optimizers can be added to these string inverters to allow for more flexibility  Also when micro inverters or optimizers convert power individually, shading on one panel won’t affect the output of the other panels. Micro inverters or optimizers allow you to get the most power from your system.






 high efficiency inverter solar 



Some systems have the capability to be monitored on-line. You can see exactly how much power your system is producing as well as identify any modules that may be under producing. If you are leasing a system you might find it interesting to know exactly how much power the system is actually providing and if the lease makes sense.
