Solar energy cost justification

Is it the problem of acquiring the subsidies from the government which is only 30 percent on 1 KW installations from the central government (Not on the 2KW - 10KW systems). Apart from that the general consensus is a solar rooftop system entails a lot of maintenance hassles which goes hand in hand with a lack of awareness. Or is it just that we still haven't developed a long run outlook which is necessary when talking about solar energy cost justification?

The intentions are there, people try to get a good branded product but none is available. To fill in the gap, local technicians create a jugged of low cost solar panels, Diode as an excuse for a charger, wet type batteries that leak and create a mess, non sine wave inverters that buzz and lead to damaged electronics. This whole thing works for a few months before one thing or the other giving up.

If a packaged solution is proposed, there are takers. They do not mind the minimal maintenance of cleaning panels. Use of maintenance free batteries is mandatory for home use to avoid the mess and hazard of acid leaking.
Subsidy is the last of all the problems of adoption of rooftop solar if you price the products correctly.

Main psychological reason is cost of installation per KW Vs the cost offset due to the solar production. People feel that 5 kwh daily production is hardly useful for an investment of Rs. 1.4 lacs.
High Interest outgo, lack of ability to run some high starting current/voltage applications make the output of limited use.

We cannot start an AC with small system or even refrigerator or heater etc. Unless you have those highly efficient motors/compressors that are currently priced at higher end. The issue is that you will need to ask the customer to change his AC, refrigerator and that means replacing his white goods. This defeats the economy etc.
Even when you suggest that the customer use LED bulb as replacement and make a pay back period estimation you compare with other old tech luminary and also take its price into consideration. But what we miss out is that poor chap has already bought that old luminary and has to buy an LED on top of that.

About the systems it is a sum of parts. PV panels, DC charge controller, Battery bank and Invertor (if you want AC power). I can offer some important components, but if you want to get any subsidy then you have to get it from an MNRE approved/listed supplier.
Others may correct me.

I suggest that those who can, should offer their products and try to design an ideal solar inverter system in some sizes (on paper initially). That way all can source and supply some products and everyone can market the solar inverter systems thus built to their own target audience.
