Photovoltaic solar energy photovoltaic effect is a physical process through what the photovoltaic cell turns the solar light into electricity. The solar light is compound of photons.When the photons hit the photovoltaic cell and are absorbed by this one, they generate electricity. This it happens because the energy of the photon is transferred to the atomic electron of the photovoltaic cell (material semi conductor).The photovoltaic cells can be made with different materials and technologies. Some of these technologies, used in the most commercial modules, include monocrystalline, polycrystalline and amorphous silicon cells. Using this technology each cell produces a tension in DC of approximately 0,5 volts and one intensity in DC from 1 to 8 To, requires an appreciable amount of cells to produce an appreciable voltage and a power.

The photovoltaic cells are interconnected to each other in series in groups that go of 36 to 72 cells that they produce a voltage to abierto circuit of approximately 20 to 40 volts this set of cells conform a photovoltaic module. Solar water pumps the solar pumps are designed to work in direct current provided by a photovoltaic adjustment. Due to the nature of the solar energy east type of systems must take advantage of the solar energy to the maximum, need to maximize the liters of electrical water pumped by watt consumed. Also they must of being able to pump water during periods of low insolation. Submersible and superficial solar pumps exist. The superficial solar pumps are placed near the water source, are much more economic that the submersible pumps, pump little water per day, they are in centrifugal models and of positive displacement (diaphragm). The submersible pumps are introduced within the water source, are made in stainless steel, they allow to pump great amounts of water to little height, or little amount of water to high altitude, for example: a pump centrifuge multi steps it can pump 100.000 liters of water to the day to 10 meters of height, a pump of positive displacement (rotor helical) can pump to 200 meters of height 5.000 liters per day.

Improve Outcomes

The microblogging and Twitter are a very popular social phenomenon. The companies already use this 2.0 social tool. We can use Twitter in conjunction with email marketing to improve business results.The first step is to fit the profile. In him we are going to reflect what we do briefly. In addition to who we are or what we do, can be inserted within the own Bio an incentive for potential fans, in such a way that fans have access to any document of value.On Twitter we can also place a link to the web page. This link can be to home page of the website, or to a landing page (land page) that is optimized for capturing contacts, through subscriptions to a newsletter, download an ebook or any product specifications. Also special discounts can be offered to fans.An important element is to thank its presence via a direct message to new followers.This process is simple if we have few followers, but when the number is high need automate it. For this purpose there are tools with Tweet Later, that lets you send these direct messages of thanks and also send a download access if we have offered something new followers.Another of the possibilities of Twitter, is that messages not only to write to the website, but that addition can write from the mobile.Also, the contents of the web page or blog can directly be announce in the Twitter account when there is something new.

Other tools that allow you to use Twitter for business is, another is All of these utilities allow to improve the interaction of Twitter, by machining processes, scheduling tweets, looking for potential supporters, looking for tweets that cite your name of user in short, Twitter is a great tool to use in the business. It is only necessary to start creatively and encourage people to follow you.
