Diesel Generator vs Solar Generators

Criteria	Diesel Generator	Solar Generator
System Type	Portable diesel generator set	Portable Solar generator
Cost	Lower initial cost, high running costs due to fuel consumption	High initial cost, virtually free for lifetime.
Maintenance	Require periodic maintenance such as oiling of parts and replacement of moving parts	Minimum maintenance required due to no moving parts.
Pollution	Noisy, smoke discharge and greasy residues.Also harmful for the environment	Soundless, no discharges.Environmentally friendly.
Efficiency	Will consume fuel and produce constant energy regardless of load consumption. Most of this energy is wasted.	Will store extra energy and supply it when required. All energy is utilized.
Cost per kWh	Increases with fuel prices	Free after sometime.
Return on Investment	None	Cheaper than grid power over its lifetime.
Reliability in Rugged Conditions	Will function when required, but lifetime will be shortened by environment.	Will function when required, and is ideal for sunny countries.
Fueling Costs	Requires fuel to be transported to location and manually inserted into tank	No cost for fuel. It is automatically charging at all times in the sun.
Set Up Time	Will have to be refueled before being used	Deployed in a few minutes.
When Not in Use	Nothing will happen, though fuel level will have to be checked before reuse	The generator will retain charge. It will continue to charge as long as exposed to sunlight.
Towing from Location to New Location	Refueling needed when moved to a new location	Generator will charge en-route, ready to be used when arriving at new location.
Life Time	3-5 years with daily use	Up to 25 years.
