Your Questions About Solar Energy Generators India

Power Generator for travel trailer – alternative energy kinds like biodiesel or hydrogen or solar?

We have a 27′ older travel trailer we’ve parked in the woods. There is no water, no power, no electricity. We’d like to turn this old dinosaur into an experiment in off-the grid cottage (start off with trailer and build around it). One thing is a power generator. Does anyone know if biodiesel (i.e. vegetable oil) portable generators exist or if perhaps hydrogen generators? This would be a back up to a solar panel hooked up to the trailer battery. Also looking into how to build a well and septic system. Links to books or examples of websites or other resources would be nice. Piece of land we have is in Quebec. P.S. not sure which category to put this in, there’s nothing on alternative energy.

Solar energy is becoming popular in rural and remote area in India. Why?
