As someone who installs these systems commercially, I highly suggest you look into what it will actually cost you. Given I haven't looked for myself for over a year, but at the time even my over 3k bill a year wasn't worth it at the time and I wasn't counting labor since I would be doing it myself. It's not just solar panels, you need a controller which depending on how you want your system to function can get very costly. Most people would still be tied into the grid, so you need to see how you energy company handles that. Will they give you a credit for energy you give to them or will they even allow it? do you need a separate meter or a different meter? make sure your controller can do what is required, its not just an inverter. Their answer might change your mind on if you want batteries or not, which adds more cost and generally need to be replaced every 7 years.
It might not even be worth it for a small room, prices go exponentially down per kw
I would be interested in what your system actually cost. As soon as it pays itself off sooner than 3 years, thats when I will have them on my roof.
