Laptops require a good amount of electrical energy for their functioning. Solar panels or cells which are used in some night lamps or Garden lamps will not be able to supply that kind of energy. Another thing is we use the laptop in a shaded environment and we don't use it in open under Sun so whatever small amount of electrical energy that is being converted by the proposed solar cells in the shade or the conditions of less light will not suffice for the purpose.
Right now we can only say that it is the limitation of technology because solar cells can produce very low electrical energy in the environment where low-intensity light is available like inside a room.
Calculators, small toys, and fancy items where power requirement is low can work on a few solar cells mounted on them.
On the other hand, the solar panels which are mounted on rooftops in our country in many states where good Sunshine is available, they are producing a good amount of electrical energy which is connected to the main grid, and people are getting benefitted from that electricity produced on their rooftops using the solar panels.
Knowledge is power.

Almost many products in the present period are having some lacuna in them. Producers of such items are giving way to other producers who are making parts or accessories, indirectly. Repairable items also not in the market at present, many service personnel are suggested to through out the products got stuck up and go for a new one. In some genuine repairers only we can expect co-operation to get our products repaired or serviced. I have a watch of my father, of course, it is very old. Though the watch unit is not working I was having interest to use the chain strap of the old watch into a new one of mine. I took the old and new watches to a service person and asked him to replace the chain strap in the new one. He simply replied that the old chain strap is useless and could not be used in the new one as the link pin is not available in the market. I simply take back both of them and kept in my brief case. After a gap of two months, when I went to Madurai , casually noticed the old watch in my briefcase, so with a chance I took both the watches to a service shop in Madurai. The person who was on the board, just scanned the old watch, removed the watch from the strap and without saying anything he attached into the new watch with a pin from his box. He simply gave the watch to me and asked Rs.25 for servicing. I got stunned and before I am giving the cash to him, an old man came from outside, later understood that he is the father of the person on the board, took the chain in his hand and asked me whether I know the year of manufacturing of that chain. I replied that I was not aware. He himself replied, 'Do not throw out the chain as it was made in 1955.

It is not feasible and convenient as of now.
As the laptops are not always used in bright sunshine outside, the panels will not be getting sufficient sunlight to charge the battery. o it is not a practical idea at this juncture.
As laptops are to be use in night time also, there should be electric charging also. Attaching such dual charging facility can increase cost and space and add to causing more issues.
Hence unless some better technology is found, it is not a practical idea now.

You can use a solar panel to directly charge a laptop. But the solar panel with a rating of 60 to 100 watts and voltage of 18v or above. f the voltage doesn't match then the laptop will not get charged. A 60-100watt panel can be sufficient to get 5 amps on a sunny day. But most of the solar panels are 12V rated only. Maximum voltage may go up to 14V. The amperage from these normal panels is also very less and can't charge the laptop battery.
But these panels require sunlight to generate power and we may not be sitting always in the sunlight. So at this moment, practically the idea may not work.
