Strawberry Tree (solar energy device)

Strawberry Tree (solar energy device) is a physics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Strawberry Tree (solar energy device) rather than just read about it. In short: The Strawberry Tree is the world’s first public solar charger for mobile devices. It was developed by Serbian company Strawberry Energy.

Key takeaways

Strawberry Tree (solar energy device) belongs to physics; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Strawberry Tree (solar energy device) to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Strawberry Tree (solar energy device) from memory before moving on to harder problems.

Reference excerpt

The Strawberry Tree is the world’s first public solar charger for mobile devices. It was developed by Serbian company Strawberry Energy. It won first place in the European Commission’s "Sustainable energy week 2011" competition in Brussels, in the category Consuming.

Functionalities Strawberry Tree is a solar and WiFi station which is permanently installed in public places such as streets, parks and squares, providing passersby with the opportunity to charge their mobile devices for free when they are outside. Its main parts are:

Solar panels that transform solar energy to electrical energy Rechargeable batteries which accumulate energy and make Strawberry Tree function for more than 14 days without sunshine Sixteen cords for different types of mobile devices such as mobile phones, cameras, mp3 players etc. Smart electronics which enables balance between produced and consumed energy Also, Strawberry Tree provides free wireless internet in the immediate surroundings.

History The first idea of a public solar charger for mobile devices, Strawberry tree was developed by Miloš Milisavljević, founder of Strawberry Energy company. As of 2013, there were eleven Strawberry Trees installed. The first Strawberry Tree was installed in October, 2010 in the main square of Obrenovac municipality, Serbia. During the first 40 days from presentation of the solar charger, 10,000 chargings were measured. One year later, in cooperation with Telekom Serbia Company, a second Public solar charger for mobile devices was set up in Zvezdara municipality, Belgrade, Serbia. In the same month, a third Strawberry Tree was set in Novi Sad, Serbia. By the beginning of 2012, more than 100,000 chargings had been achieved on all three Strawberry trees. In cooperation with Telekom Serbia Company, Strawberry energy also installed Strawberry Tree at these locations:

Kikinda, Serbia, in July, 2012. Vranje, Serbia, in August, 2012. Bor, Serbia, in October, 2012. Valjevo, Serbia, in October, 2012. In cooperation with city of Belgrade and Palilula municipality, Strawberry energy installed Strawberry Tree Black in Belgrade in Tašmajdan Park, in November 2012, with a completely new design by Serbian architect Miloš Milivojević. In the beginning of 2013, Strawberry energy, in cooperation with the city of Belgrade and Mikser organization, set up Public solar charger Strawberry Tree Flow with the new design by Serbian designers Tamara Švonja and Vojin Stojadinović, in Slavija square, Belgrade, Serbia. Later in 2013, through the project "Bijeljina and Bogatić – together on the way towards energy sustainability through increasing energy efficiency and promotion of renewable energy sources" within Cross Border Cooperation Programme Serbia – Bosnia and Herzegovina, two solar chargers have been installed in Bijeljina: in front of Cultural center and in the City park.

Worked examples

Example 1 — a first encounter with Strawberry Tree (solar energy device)

Start with the simplest possible case. Write down what Strawberry Tree (solar energy device) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Strawberry Tree (solar energy device) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Strawberry Tree (solar energy device) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Strawberry Tree (solar energy device)

In research: Strawberry Tree (solar energy device) appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Strawberry Tree (solar energy device) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Strawberry Tree (solar energy device) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2010 establishments in Serbia, Applications of photovoltaics, Battery chargers, so understanding it makes those chapters shorter.
In everyday life: Look for Strawberry Tree (solar energy device) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
