What cost does it take to install solar power panels?

I recently shifted to a new house and I want to add solar panels on the roof of my new house as if it will make it more eco friendly, but I have one question in mind before using it, that is what is the cost of fixing solar panels at home and one more thing will it work or its just wastage of money because the reason I am asking is that I live in UK and sunlight is not premium, I would like to install a solar panel in the garden to run the lights in my shed, any advice and feedback will be appreciated. Please help as soon as possible.
