The imagine shows aboutdiagram illustrates how humans hare taking sunness solar energy and makingconvert it into electryicity. This are bigpresents a significant advancement and help for solvingaids in addressing the problem of energy demeand. In the beginning, sunlight come to earth byreaches the Earth through radiation waves. Thisese waves have powerpossess energy but are not in a useable fourm. So experts found ways for changing this powerTherefore, experts have developed methods to transform this energy into electryicity by using special equipmient like solar pannels. Firstly, sunolar radiation falls on solar pannels. The pannels are made from special materials that absorb sunolar radiation and convert it to dyirect curraent (DC) electryicity. ButHowever, this form of electryicity is not compattible with our normalstandard appliances. SoThe next step is to send DC electryicity to an invertaer machine. This machine changeonverts DC into Aalternating curraent (AC). This form, which is now useable for appliances. After that, the AC electryicity gis sent to tohe mains electryicity grid or can go tobe stored in batteries for storage. Mains grid send. The mains grid distributes electryicity to cityies for usinge in homes, offices, factories, etc. If sendt to batteries, electryicity can be stored for use letterlater use when the sun is not givproviding radiation like at night time. So i, such as at night. In summary, sunlight is a powerfull source of energy but not directly useable. We need to use special equipmient to absorb the power of the sun, convert it to electryicity, change the type of electryicity, and send toit to the mains or batteries for humeans to use. This renewable waymethod is better for the envyironmient compare withd to coal and oil. In the future, moregreater use of solar power is expected.

Expert Feedback

The essay demonstrates a basic understanding of the process of harnessing solar energy, which is a key strength. The structure is generally clear, with an introduction, body paragraphs, and a summary. However, there are critical areas for improvement, particularly in grammatical accuracy, spelling, and the use of cohesive devices. The original text contained numerous spelling errors and grammatical mistakes that hindered clarity. The revised version corrects these issues while maintaining the original flow and structure. The structural changes made include correcting grammatical errors, improving spelling, and enhancing coherence by adding linking phrases. Suggestions for further improvements not implemented in the corrected version include expanding on the comparison with coal and oil for a more detailed analysis and incorporating a wider range of vocabulary to avoid repetition. The tone used is appropriate for an academic context, maintaining a formal and informative style throughout.

Detailed Scores

Coherence And Cohesion
The essay has a basic structure, but the flow of ideas is sometimes disrupted by awkward phrasing and grammatical errors. While there is an attempt to organize the information logically, the use of cohesive devices is limited. To enhance coherence, the writer should use more linking words and phrases to connect ideas smoothly.
5.0
Grammatical Range And Accuracy
The writing contains numerous grammatical errors, including subject-verb agreement issues and incorrect word forms (e.g., 'this are big advancment'). The sentence structures are mostly simple, with limited variety. To improve, the writer should focus on using more complex sentences and ensuring grammatical accuracy throughout the text.
4.5
Lexical Resource
The vocabulary used is adequate but contains several spelling errors (e.g., 'electrycity', 'equpmint', 'battries'). There is some repetition of words like 'electrycity' and 'sun radiation'. To improve, the writer should aim to use a wider range of vocabulary and ensure correct spelling to enhance clarity and professionalism.
5.0
Task Achievement
The response addresses the task by summarizing the process of harnessing solar energy, but it lacks clarity and detail in some areas. For example, the explanation of how solar panels work could be more precise, and the comparison with coal and oil is somewhat vague. To improve, the writer should focus on providing clearer descriptions and more specific comparisons.
