The central decisive element is cost. There are multiple elements in cost itself, and each needs to be looked at before selecting one.
The first one is an essential cost. Diesel generators have meager cost in comparison to batteries and also require lesser repair and maintenance than other fuel generators. Batteries, solar ones that are must for continuous supply, cost way higher than a diesel generator both for commercial and residential purposes.
Next is fuel cost. Although diesel generators have an additional cost of diesel fuel but setting up solar panels for solar-powered batteries is still more expensive than refueling diesel at least for a few years.
Maintenance cost in the case of batteries is negligible in comparison to other fuel generators. But since diesel generators do not have spark plugs, they require very little maintenance also there is no need for regular annual maintenance.
5. Output Requirements:-
Another major consideration is the range of output. Batteries can generate enough power to run a single household, too, with limited devices. But when several gadgets are to be used or when power usage is very high generators are the best options. It makes diesel generators the only and the best option available for commercial uses in offices and factories. Diesel generators have a wide range of output which ranges from enough for a single household to a big manufacturing unit.
# Conclusion-
So, which one is best for you, the answer is based on your requirements and environment. If you require more power supply that too high voltage for running machines in factories or several gadgets in your home, then a diesel generator should be the obvious choice. Especially when your premise is in such an area that experiences regular power cuts for long periods then also a diesel generator is best.
Also, the generator has many other benefits like simple design, sleek design, flexibility to move, silent working, shockproof casing, etc. And in a scarce case, if your power requirement is very less limited to a few devices for a few hours, then a battery would also be beneficial for your needs.
