I have a similar setup at my apartment in India. It is functional since more than two years now. Its total 140Watt panels, popping out of my bedroom window [Photo: https://photos.app.goo.gl/S4WR5gbrGu0z8IQB2 https://photos.app.goo.gl/S4WR5gbrGu0z8IQB2]. It has a 12V battery and 10A solar charge controller. It produces good enough energy to power my room. I hate inverters, all my lights/fans in room are based on DC 12V. I use car chargers to charge mobile phones and to run a LED wall clock.
