Band 4+: You should spend about 20 minutes on this task. The diagrams show the structure of solar panel and its use. Write a report for a university, lecturer describing the information shown below. Summarise the information by selecting and reporting the main features and make comparisons where relevant. You should write at least 150 words.

The report attempts to describe the components shown in the diagram, but it lacks the formal tone required for an academic report. The use of phrases like 'let's talk about' and 'it is clear from its name' is too conversational. Additionally, the report fails to fully address the 'use' aspect of the solar panel as requested by the task; while it mentions absorbing energy, it does not effectively describe the process or the function of the arrows and pipes shown in the visual. To improve, focus on using objective, descriptive language and ensure all visual elements (such as the arrows representing sunlight) are integrated into a functional description of how the device works. The report falls short of the required 150 words.

The report follows a basic logical progression, but the cohesion is somewhat mechanical. The use of phrases like 'First, let's talk about...' and 'Then we have...' is more characteristic of a spoken presentation than a formal academic report. To improve, use more sophisticated transitional devices such as 'Regarding the base structure,' or 'In terms of the upper component.' Additionally, the paragraphing is functional but could be more effectively used to separate the description of the structure from the explanation of its function.

The vocabulary used is quite basic and repetitive (e.g., using 'box' and 'top' multiple times). While the meaning is clear, the report lacks the academic precision required for a higher band. Instead of 'pretty simple,' consider 'relatively straightforward.' Instead of 'tubes coming out from it,' use 'pipes protruding from the sides.' Avoid conversational filler like 'It is clear from its name,' as this does not add descriptive value to the technical process. Boost vocabulary complexity to elevate the overall score.

The grammatical structures are mostly simple sentences. While there are no major errors that impede communication, there is a lack of complex sentence structures (such as relative clauses or passive voice) which are essential for describing processes and diagrams. For example, instead of 'the diagram shows a box on the bottom, and it has two tubes,' you could use 'The base of the unit consists of a box from which two pipes emerge.' Aim to incorporate more passive voice to maintain an objective, academic tone.
