You are missing capital letters at the start of some of your sentences.
Actually I am not sure if your trip to the shore is relevant. It depends on what you want to convey to the reader. If you want the reader to learn how you did the project that that information is irrelevant. You might want to mention what kind of line of sight you need to the sun but that is all you need.
If it is an article just for general interest then mentioning of the shore trip is not a problem.
Reading it, it becomes obvious that English is not your first language.
If you would like to fix it up for publication and at the same time improve your English you should ask someone to edit it.
Also if your just learning englist try using MS word, it actually fixes grammer mistakes and will add that period so you can see it automatically make a new sentence a capital, add a comma or period.It will also highlight where it thinks there are mistakes with nouns, verbs, etc.
