I need to now the target audience for solar lights and solar powered decorations.?

I am using the pay-per-click advertising method for my website and I want to get the most of my money and target only specific customers. This is why I want to know what kind of persons (age, gender, location) do you think would be interested in solar garden lights and solar decorations. If it helps, look at my website at www.officialsolarproducts.com to see the products that I am selling.

As for age, I would guess middle aged and gen xers are most concerned about eco things. Middle aged have more money, I would think.
