A solar heater is a device that uses sunlight to heat a substance. Its most common use is to heat water for sanitary use (showers, washing clothes, cooking, etc) both for domestic use, such as commercial or industrial (hotels, restaurants, factories, etc.). Having an operation very simple and no moving parts, maintenance is almost nil and its service life is calculated, in some cases, in more than 25 years. A solar heater can produce energy savings of between 50% and 75% in unfavorable times and between 80% and 100% in periods and zones of high solar radiation. These systems transform the thermal energy of the Sun to produce hot water and allow significant savings in the habitual consumption of gas and electricity. How work the solar water heaters of Solargreen? The water heating process starts when the Sun’s rays impinge on the surface of the collector and raise the temperature of the water circulating in the pipes. During the hours of sunlight the water temperature can reach up to 85 degrees Celsius thanks to our high-efficiency technology. Keep in mind that temperature for a shower does not usually exceed 40 degrees Celsius.

The hot water is stored in the sealed water heater supplied with the heater. It is estimated that the average loss of temperature during the night on the inside of the tank is between 5 and 8 degrees Celsius, so you can enjoy the stored hot water even during the night or the morning before that again the sun rises. Water heater Solar Solargreen solar heaters Solargreen collector Termosifonico termosifonicos consists of a series of tubes of vacuum glass arranged in series.Each of these tubes is formed by a double wall, the inner tube is coated with a layer specifically designed to attract solar radiation. The outer tube covers the first and vacuum seals the space between both tubes are eliminating convective heat loss and conductive, ensuring that all radiation absorbed by the inner tube is transferred to the water flowing inside him.

Nintendo DS Solar

We are looking for a battery charger of solar energy, with an internal battery 1200 mAh, power LCD screen and a series of advice of charge at an affordable price.Charger battery that uses solar power always causes controversy when it comes to marketing and reality demands. Since it depends on a good level of lighting, solar panels in the United Kingdom will always be somewhat at a disadvantage. Fortunately the classic charger Freeloader of batteries is not limited to charging a device in real time, but it loads an internal battery (1200 mAh capacity).The manufacturer stresses that a full charge is possible in eight hours when conditions are optimal. Realistically, in a day cloudy in March charging time is result insignificante.Como, the best option for charging the internal battery is charged from a more traditional from the computer power supply (desktop or laptop). This can be done using the supplied mini USB cable.

If you have a red battery charger with an integrated USB connector that comes with many new mobile phones now, you can drastically increase the charging time. Battery charger when not in use you can unhook one of the panels and connect it to the face of the other, protecting the two panels. The disadvantage is that this stops charging the battery completely. Also bearing in mind that each panel is detachable, the possibility of losing one or both solar panels.In the box with this battery charger comes a series of tips for charging different devices, from most popular mobile phones (including those with mini and micro-USB) until digital cameras or portable Nintendo DS console. You also get a normal USB connection, so you can use any cable that you have.Another feature of the classic charger Freeloader of batteries is an LCD screen that gives the detailed measurement of the battery charge. What you can do is to get an instant reading.

When this battery charger is plugged into a computer or network, is also lit with a blue backlight. When charging from the solar panels, the lighting is off, since it is clearly not necessary. It would have been good that this battery charger has a button to quickly see the charge level when not in use. In general, the classic charger Freeloader of batteries was a little disappointing. As a portable battery charger (ignoring solar panels for a minute), worked perfectly, in addition to requiring a cable mini-USB instead of the industry standard cable micro-USB. As almost all new mobile phones now use micro-USB. At present, solar panels should be considered as an added advantage that can be useful when the climatic conditions are ideal, or if you are traveling abroad where a light level is stronger and more powerful. In other cases, for you it is probably best to buy a normal battery charger without solar panels.
