changing solar panel from 15W/18 to ??

asked 2017-06-20 05:28:40 -0600

Hello all,

This is my first post here, I am from UAE and since we have plenty of sun throughout the whole year here, i thought of using this to my own benefit. Therefore, I decided to buy this solar fan (from manufacturer in China) which works direct from the sun (day time only); as I am using it for the animals that I have i my barn during the day time (hot time). Now here is the problem! I discovered that the fan speed isn't that good! meaning not so fast/quick! As I am hanging the fan under the ceiling of the barn and the ceiling height is about 1/70 cm = about 6 foot. ** I have about 15 house of these small animals cages... each has it's own solar fan. Well, i contacted the company and they've told me that I can change the solar panel from the current 15W/18V solar panel into a PV module of 30W/24V, or 40W/24V ! Here I am honestly lost! Since i don't have any experience in this type of fields, i decided to ask this questions here and see what are the feedback before doing anything further with local suppliers of solar panels. Thanks all in advance, Mohamed
