Prasad IMAX in Hyderabad, in the state of Andhra Pradesh, now has the distinction of being India’s first “green theater”. It has achieved that feat by installing 100KWp solar photovoltaic power generation system on the roof of the theater.

Here is a Spreadsheet to estimate costs of a Solar Grid Tie Kit based on average consumption. The advantage with Grid Tie Kit is that when the solar panels are not producing enough power due to shade or other reasons the system compensates for it from the mains.

A medium sized office consumes about 5KW and costs around Rs. 7 Lakhs (12,500 USD).

Solar power should first be utilized where we do not need to store power for later consumption (Night). Offices functioning only during day time are good candidates for Solarification.

There is another often overlooked socio-economic problem associated with using solar power in homes and agricultural fields. Given the high value of the installed equipment they are lucrative targets for goons everywhere, more so when they are installed in far away fields.

Indian Government should make it a priority to protect these assets and make stealing them a non-bailable offence with rigorous punishment for the guilty. There should be a registration system in place similar to that available for automobiles. Buyers should register their solar panels and always check their purchase against a database available online.

Yes this should be implemented or else we will face many issues later.But again we cant maintain another department for registering this products,this should be done by the existing departments in India(like Fire,Postal departments) is what I think.

It should be a system built on Public Private Partnership (PPP) model or else its difficult to control corruption.

RFID and 3D Glass Etching can be used to tag each panel above 200 Wp and that id can be used to register online. The system should preferably be maintained by a consortium of companies involved in Solar related activities and those who directly benefit from the rising sales of Solar systems.

Approximate Solar PV System Capacity:

Daily Solar Insolation (KW / Sq. Mtr. / Day)

X

Rated PTC Capacity of System

=

Total KWh / Day

Eg: Each Solar Panel (210 W PTC) will produce around 1.05 KWh per day with an average insolation of 5 KWh / Sq. Mtr / Day.

Refer to the attached map for Insolation readings across India.

For an accurate calculation use this online calculator :-

What is abundant in India? Sunshine. Solar panels are the best option for generating electricity in India. The problem with solar power is that the panels produce electricity at different amounts based on sunshine, clouds, shade etc. This problem can be mitigated by connecting the solar panel power to the national grid. Government has to give incentive for producing solar power. UK and German governments have introduced a scheme to encourage residents to generate solar power on their roofs. By this, the government or the power companies pay incentive for producing solar power. UK government is currently running a scheme by which each unit of solar electricity produced receives £0.16 per KWh

So any ideas for spreading the Solar value proposition to the masses?

Prasad Botu, Evangelist - 6 years ago Edit
Solar power can be best utilised in villages where the shade from adjacent buildings not there much. Solar power linked to grid is only solution. Feed in tariff, the one that is there in UK is the best option.

Praveen Baratam, Maven - 6 years ago Edit
Buildings shading other buildings is an important concern in cities which has been overlooked so far in every discussion. @Prasad you brought up a very important issue.

Regarding space requirements, except for tall buildings housing a large number of inmates the roof top is sufficient to provide adequate power (120W per Sq.mtr). We should first plan to use solar power where we do not need to store power. Batteries are expensive.

Praveen Baratam, Maven - 6 years ago Edit
To compensate for low sunshine hours, we have to use Grid Tie solar systems. When solar power is inadequate the system will draw power from the utility power supply and compensate. Overall we can reduce significant load from the grid this way and grid will do the balancing act when necessary.

@Praveen, what u stated r very good points i have a doubt regarding 120w per sq m generation, is this value a average value or peak hours value, can you plz share some points regarding this
Save Cancel
 
Praveen Baratam, Maven - 6 years ago Edit
Every Solar panel has PTC rating which gives us an estimate of how much power it will produce in ideal conditions. These ideal conditions exist for about 5 hours in a day and capacity will be lower during other hours. 120Wp / Sq. Mtr. is based on PTC.

Right. Only thing govt can do, is to provide some subsidy for the private industry which uses them
Save Cancel
 
Praveen Baratam, Maven - 6 years ago Edit
Actually subsidies work against the economic well being of the country. What our Govt. should do instead is to pass on the actual costs of producing and distributing power to the consumer with out any subsidy. Then solar power becomes comparable in price to utility (Govt.) power.

Businesses and enterprises will be able to claim tax rebates and depreciation by investing in Solar.

In USA many companies lease out Solar equipment to households and charge them the same price every month as the utility power companies do. They are able to do that because Govt. does not subsidize power. http://www.solarcity.com/residential/solar-lease.aspx

Around 40% of electricity produced in India is used for Irrigation. That's a huge chunk of the pie worth optimizing. We cannot increasingly burn coal to meet these requirements.

In contrast to domestic and industrial sectors which often require a dependable and continuous supply from the grid, Irrigation can use solar and wind energy which by nature are not continuous but can be harvested in plenty. Irrigation can be effectively managed with supply only during day light hours and its reliance on Grid is sub optimal.

The key is Distributed Generation or Local Generation which minimizes losses and maximizes efficiency.

There is no point in blaming the system for anything. We cannot mend anything that way. We have to push for self sufficient villages as the building blocks of our nation.

Very true. Who will bring this up? Would a common village farmer know that he has alternatives?

What is needed is a change of attitude..... to be self sufficient.... we buy land, we buy our home, we spend millions on it because we think of them as assets. We also need to invest on our necessities and reduce the burden on public utilities.

Bio-Fuels - Palm Oil (Crude Palm Oil)

India consumes 558 million liters of petroleum / day (Approx as of 2013) i.e. 204 billion liters / year. [1]

Oil Palm Yield - 2400 liters / acre [2]

Required crop land - 85 million acres
Total Agricultural land - 444 million acres. [3]
Utilized Agricultural Land - 391 million acres. [3]

Un-utilized agricultural land of 53 million acres itself can reduce oil imports by 60% and bio-fuels are carbon neutral :-)

Palm oil refining may need a chemical process depending on the required output quality but it is still doable.
