Expert Answer

Cost analysis of solar system in comparision to conventional system is not related to physics.

I do not know what is referred as conventional system. Does it refer electrical power provided by local electricity board?

Or Does it refer to the petrol/Diesel based generator system?

Solar system involves huge upfront cost , i.e., required initial expenditure .

Cost of Solar panel and cost of installation itself is very high that can be obtained from manufacturers of solar panel.

In addition to solar panel , equipments like inverter are required to convert DC power from solar panel to AC power

that is required to operate domestic electrical utilities like refergirator, MW oven etc .

This initial procurement and installation cost is not so high for conventional system .

Solar panel will not produce electrical power during night time or when sunlight is absent during rainy days.

Hence expensive storage batteries and charging system is required to buy.

Only advantage in solar system is there is no fuel cost which is required for petrol/diesel generator.

No electricity bill payment is to be made for solar panel where as we need to pay electricity usage charges to electricity board.

Maintainence cost also high for sloar panel system because it is exposed to environment.

Lifetime of solar panel system is also uncertain

Hence costwise , there is no attraction to use solar system compare to conventional system .

It is stated that solar panel produce clean energy or green energy that does not pollute the environment.

But solar panels are produced in factories and those factories will create pollution to some extent.
