Solar umbrellas, which can already be found on the worldwide market, all have in common that they can only generate small amounts of electricity due to small module areas and therefore are rather useful in the private sector. The innovative feature of our umbrella is the enormously large collector surface, which is firmly integrated into the struts, and which can produce so much electricity that its use in the commercial areas of gastronomy, hotels and events creates a great added value. At the same time, as a telescopic center pole parasol, it meets all the requirements of a professional sunshade. It can operate light, music and W-Lan, in addition all USB devices can be charged and connected. This is also possible for notebooks, e-bikes, lawn mowing robots and cooling devices. Depending on the design, the battery storage units integrated into the pole or umbrella base are charged with sunlight during the day and can then continue all daylight functions after dark. Although it is basically similar in design to a classic parasol, its black modules make it immediately recognizable as a "green power plant" and electricity charging station, and can thus generate added value in the catering industry. At many locations, connecting the parasols to the power grid is very complex and expensive (earthworks, laying cables, electricians, permits, etc.) at others it is even almost impossible (historic alleys and squares, serving areas separated by public roads and paths)... this means that lighting, sound, W-Lan and charging options are not possible there with public electricity. All these hurdles are easily overcome with the umbrella. In addition, it charges the batteries even when closed and also protects the textile parts inside. These can also be individually replaced and printed. Around the Mediterranean Sea are hotels with beach access, where guests can rent umbrellas and sunbeds. The length of stay is long. Renting a solar umbrella for an extra charge offers the possibility to charge cell phones and tablets, run a fan or an electric cooler. Since a larger number of berths (20 - 50) can be assumed for each hotel, even partial provision of solar umbrellas already results in an interesting turnover. In addition, another point deserves attention: Normal household electricity with 220 volts, laid near water (sea, inland waters, pools) can be installed, if at all, only with great safety effort. The solar umbrella works with harmless 12 volts and can therefore be used near water without hesitation. Our Model 3 with a diameter of 4 meters has gel batteries with a capacity of 48 A/h under its tabletop mounted on the mast, sufficient for charging and operating at least 5 hours each of light, W-Lan repeater, music sound system and USB recharging..... all at the same time and after sunset! With a model that has e.g. a 100 A/h battery storage integrated in the base, the above values double. If you now look at the performance during daytime operation, i.e. when the sun is shining or when it is slightly cloudy, the performance increases significantly and consumers with higher power requirements, such as e-bikes, pedelecs or coolers, can be charged or operated without any problems. For open-air events, the clear advantage of the screen is that there is no need for complex cabling, it can be set up anywhere and dangerous cable trip hazards are avoided. Individual additional components and designs can be ordered for the basic screen.
