Is there a way to price control items by units times a solo price input?

Hello peoples, I really need some help or a push in the right direction with this one.
I have a Solar panel shop and i need to be able to change the price per watt.
example, Lets say there is a company ozzysolar panels i have 3 panels from them a 200w, 250w and a 300w panel lets say i get them for $2.00 per watt, i need to be able to input a price per company as each company has different prices and have it working out each panel price.
Is it possible to do this?
Any help would be greatly appreciated thanks in advance

I answered this in your previous post. What about what I suggested (attributes) didn't work for you?

A multiplier based on manufacturer would require considerable custom coding.
