With the onset of upgrades in technology from using traditional generator system to solar generators system, people have found an off-grid approach to save themselves from the blackouts. US households and businesses are shifting to a personalized or portable solar generator. These portable solar generators are in great demand because it emits no noise and fumes, or doesn’t need constant refilling of fuel.

The hybrid emergency backup system is also one the aspect of upgraded technology which is profitable these days. The hybrid suggests an amalgamation of the solar backup system and gas/diesel generator. It isn’t possible that solar energy is always available or batteries are charged up. In order to look for a solution, we have a hybrid which uses solar energy and charges the batteries too. When the solar energy isn’t available, one can switch to battery backup.

As per a journal, if we start using solar power for most of our critical needs we can have free energy for 2/3 or 3/4 of the year.
