Yes its profitable. I suggest to check info about solar panels here https://a1solarstore.com/colorado-solar-information.html Solar energy is that produced by the Sun’s light – photovoltaic energy – and its warmth – solar thermal – for the generation of electricity or the production of heat. Inexhaustible and renewable, since it comes from the Sun, solar energy is harnessed using panels and mirrors.

Wow, the difference is really significant. I'm just starting to switch to solar power so I haven't noticed much difference in terms of electricity bills. However, I try to actively buy new equipment, say, a solar controller, solar panels and other necessary devices. I believe that solar energy is environmentally friendly and economical, so we should use it.
