Something you should know about solar power system

First, what is PV? It is a term used in the solar industry referring to photovoltaic. This system is specially made for a house and generates electricity with the solar panels in it. It is part of distributed solar power generation which includes residential and commercial solar power generation forms. Commercial one mainly refers to those systems installed on commercial buildings like office, school, factory and other kinds of buildings. By adopting this, electricity can be generated inside a house and doesn't have to depend on the local utility grid any more. Currently they can be divided into three groups: grid-tie, off-grid and hybrid systems.

The grid-tie system is now the most popular one among the three, and its advantages are most obvious. It can keep supplying electricity to your family all day long without a pause, making sure your house will never meet blackouts unless the utility grid fails. It is often cheaper than a system which has storage batteries, which often cost much. This makes an off-grid system disadvantageous, but people living in remote areas can use it to drive away darkness. 

The second feature of the grid-tie system is it cannot only help save money, but also it can earn money from the utility grid, for your unused electricity will be fed back to it, which will pay you according to how much electricity your system feeds to it. Besides this, you can also get incentives from the local government if it approves your system. The best functional system is the hybrid one, which integrates the features of the two former ones. Therefore, it is connected to the grid and also has storage batteries. The most prominent disadvantages of it is that it costs too much.

 

Among the three systems the most important components are solar panels used for generating electricity and PV inverters used for converting direct current into alternating current. And so they are the most important components. In addition, if the system is an off-grid system which needs batteries for power supply when it is dark at night. Without them, the system would be discarded by users. So, they can be one of the most important components in such a special PV system.

When installing solar panels, you should know that these things should be installed on your rooftop where rich sunlight reaches everyday, and they should be adjusted to certain angles so as to absorb the most sunlight to generate electricity. If your roof has no enough space, you should consider buying highly efficient ones. Before buying PV inverters, you should make yourself clear what types are what you really want and are most suitable for your system. 

Usually people buy string inverters, but sometimes they buy micro inverters because they are more efficient but more expensive. When you maintaining the system, you don't have to worry too much, because you mainly need to clean off the dust on the solar panels three or fours a year in common conditions. But if it snows too much and your panels are covered with thick snow, you will have to be more diligent. The inverters don't require too much time for maintenance as long as you install them in dust-free and moisture-free places. In fact, micro solar inverters are usually installed under solar panels.

It depends on your choice. On average conditions a family only needs a 3 to 4 kW system, which generates about 4,000 to 5,000 kWh of electricity each year. A few families may need a bigger one. A 5 kW system might meet their needs, for it can generate about 6,000 kWh of electricity each year.

The development of solar power systems - from the earth to the moon

Obtaining home solar power can be one of your wants if you want to conserve your funds on electric power expenditures and want to do a little something superior to the earth. Given that it is a thoroughly clean energy and you can use it as a lot as you want devoid of destroying the mother nature, it is advisable to discover on the use of home solar power.

At the instant, this style of power is still an pricey in comparison with other energy resources. This is simply because the system is still not truly effectively-recognized and the tools is still pricey. It is believed that the cost of a new solar power panel will get started from a few thousands bucks to a hundred bucks relying on the dimension of your property and the reason of the use of this style of power. Even though I have reported that, I have to emphasize that the cost will be greatly decreased if we make the system by ourselves.

Is it possible to make your personal home this sort of system? Of course, it is. There are a lot of strategies that you can establish solar panel which is the instrument for collecting energy from sunlight. There is some data that you can buy inexpensively in buy to establish your personal panels. 

The superior news is that the components essential can be ordered from the local components retailers. And the approach is rather quick. You can complete the manufacturing inside of 2 days. Aside from, the cost of the manufacturing is in the assortment of just a few hundred bucks. This is why we phone it affordable solar power.

Constructing your personal panels in buy to offer you affordable energy can be 1 of your objectives. You don’t have to invest a lot and can still be able to enjoy the conserving on your energy expenditures.

A boy in US has used powder from a local quarry to simulate moon dust as he plans to develop a renewable solar energy system that could be used on the moon.

The American Society for Civil Engineers has invited Bonanno to explain his research at the Earth and Space 2012 Conference in California this weekend. Using basalt from a quarry on the central coast to simulate moon dust, he has developed solar thermal energy blocks that are lightweight and easy to transport and store.

This is crucial to provide a constant source of power in an environment of extreme temperatures that range from 123 degrees during the day to minus 233 at night.

"The lunar environment is quite a complicated place. There is no water on the moon, and there is a very large temperature variation between night and day, lots of radiation, lots of meteorites," the Sydney Morning Herald quoted him as saying.

"You don't have solar power during the day and don't have sun during nighttime, so you need a way to store heat. Current methods involve high-temperature concrete to generate electricity or heat during the night so they have a continuous supply of energy, or using liquid salts," he said.

Bonanno's method proposes using lunar soil rather than terrestrial materials to make the exercise more economically viable and more suited to the environment.

Micro solar inverter is the revolutionary development of the pv industry

In recent years, solar power has become completely modular, that is good news for potential system owner. In ancient times, it is necessary not only to buy a solar cell module, but the battery is good. This greatly increases the cost of your basic system. In 1991, First Solar SMA Solar Technology (the world's largest solar energy equipment company) production of "grid inverter." 

Solar inverter is still the key, all the solar projects. Due to many reasons, Chinese PV industry has been in a cold winter. For this, Chinese government has published many detailed policies and regulations. Chinese PV plants have sprung up. As the main part of the photovoltaic plants, PV inverter, especially the micro inverter, due to their large power amount, longer life and easy installation, have been favored by PV companies.

The DC main transit of micro inverter is to exchange from a single solar module and every single solar panel module has equipped with inverter and converter function. Every module can do Separate current conversion so as called micro inverter. Micro inverter can achieve the maximum MPPT, which is the advantage superior to central inverter. Then, the output power can adjust by the output power monitored by modules to maximize the output power.

As before, many inverter suppliers have to spend much time explaining the advantages of micro inverters and they also recognized, but many customers still beat a retreat due to the policies. With the publishment of national policies, the market of micro inverter has a good market prospect.

Speaking of centralized inverter, many domestic customers have realized of it. The centralized inverter has few advantages in distributed power projects. And the shortcoming, such as small power amount, short life and inconvenient maintenance, will heavily affect the system stability, which may cause the benefit loss of investors.

During the tough time of PV industry, the relevant companies will be like Phoenix Nirvana and the micro inverter may bring the whole industry a rebirth. The time to Ignore the power generation, power plant life, malicious competition from cheap has gone. This is the great fortune of the photovoltaic industry.
