How a solar powered water pump works

Solar power usage to transfer water from low level of soil to the countryside

A presented picture reveals the way water pump works with aid of solar power. Generally speaking, it is clearly seen how solar power cells absorb light from the sun to generate water from underground level to fulfill villagers' needs.

First of all, to transfer water from low level of soil to the countryside, it requires some supporting equipment. They are solar panel photovoltaic cells, DC power from panel, water tank, and bore pump. Material used in this process is mainly solar power from sunlight. In the beginning, solar panel is built next to the immersed-bore pump, which goes down underground after drilling to be well. Afterwards, substantial amount of light is captured by the solar cells that are transformed to be electricity through DC power.

Secondly, such converted current will encourage water from the lowest level of well turning up. Water will be gone up to water tank by helping of electricity, which will be flown in to the village. Next, it will be utilized by societies in various necessities. (170 words)

OK mistakenly posted only half message first. Here's the full one.

First, Solar powered pump does not generate water, they generate electricity for pump to suck water from ground level (solar power cells absorb light ...).

Second, your way of defining the process is wrong. it requires some supporting equipment. They are solar panel ... Diagrams showing a process aspect are supposed to be explained in a step by step manner. For example, in this case, When subjected to sunlight, the photovoltaic cells in the solar panel generates DC power, which is then used to drive the motor of the bore pump. The pump then sucks water from the underground well which is then collected in a storage tank before distributing it to the village.

There are some conceptional mistakes as well in your essay, such as Solar cells collect light not capture it and DC power is not an equipment but a form of electricity. Hope it helps.

Nur, you need to learn how to improve your overview statements. These are the opening statements that should offer a clear paraphrasing of the prompt, discussion topics, and the order of discussion within the paragraphs of the essay. Once you accurately develop a strong opening statement, you will immediately gain a chance to receive a higher score in the reading and comprehension area of the scoring requirements. This overview is not as strong as it can be even though there is a very clear method of presentation that could have allowed you to earn the higher score.

The second paragraph also fails to properly impress the examiner because you summarized key points of the discussion into one, over informative and yet still under developed paragraph. Try to limit yourself to only one topic per paragraph or related topics per paragraph. Discuss the materials first, then the water pumping procedure in the next paragraph.

Overall, the essay can probably earn a score of 5 due to the lack of information analysis on your part.

Hi @Holt
Thanks for your regular and constructing feedbacks


could you give me those suggestion details?


Is it okay to explain the materials only in one body paragraph like this?


or how if i may write at less than three sentences?

I will not repeat the suggestion details anymore because I already explained it in the previous thread observation that I posted. It is in the earlier part of the first paragraph discussion. We are not allowed to repeat information in the threads so you have to read it again. Doing so will also help you to develop your analytical reading skills, which will come in handy when you do your next practice test. Yes you can discuss just the materials needed in one paragraph. That is because the diagram clearly explains how each material is used and as such, the use of the material can be included in the paragraph. This creates a strong basis for the pumping procedure in your essay discussion. I will not write any more examples for you. I have explained enough of the problems with your essay. Showing you how to write this essay properly, after it has been scored will be useless. Just do better in your next practice test by applying the advice you were given for this exercise.
