Rooftop solar power plants

Is there money to be made on your roof? 
With the never-ending availability of sunshine and the evolution of solar technology many are recognizing the benefits of solar.

"As sunshine never ending, we think the same should be true for the knowledge around solar energy." - INSTITUTE OF SOLAR TECHNOLOGY

A rooftop solar power plant works by generating electricity from the photovoltaic modules put up on the roof and feeds it to the building for its internal consumption. A 100KW rooftop solar power plant covers 1,500 square meters of roof area reducing the peak electricity demand on power grid and DG sets while simultaneously improving local air quality.

Soon, individual households and enterprises in the State that generate their own solar power on their rooftops and share any surplus with the State grid can expect to reap monthly cash returns from their energy utility — or at least a slashed electricity bill, according to senior government officials.

Dr. Prasad said, “The government will purchase every single unit generated from any source in the State. The consumers will get a cheque delivered to them in case of supply to the grid.”


The Karnataka state government is set to revamp its  with far-reaching features, in an effort to achieve self-sufficiency in  by 2016.

As part of the overhaul of the existing energy policy, the government intends to introduce an incentive scheme for domestic household consumers, to encourage them to install rooftop solar panels to produce electricity for self consumption and supply to the grid.

Any household installing a solar panel for this purpose will be paid for the surplus energy supplied to the grid after domestic consumption, said , Chief Secretary of the Karnataka Government said on Wednesday at the CII Partnership Summit in Bangalore.

“The government will purchase every single unit generated from any source in the state,” said Amita Prasad, principal secretary, department of energy, Government of Karnataka. “A meter will be installed at the households to measure the consumption and transmission of power produced from rooftop solar panels and the consumers will get a cheque delivered to them in case of supply to the grid.”

Carbon Footprint of an Average in Indian

What is a carbon footprint?

The total amount of greenhouse gases produced to directly and indirectly support human activities, usually expressed in equivalent tons of carbon dioxide (CO2).

In other words: When you drive a car, the engine burns fuel which creates a certain amount of CO2, depending on its fuel consumption and the driving distance. (CO2 is the chemical symbol for carbon dioxide). When you heat your house with oil, gas or coal, then you also generate CO2. Even if you heat your house with electricity, the generation of the electrical power may also have emitted a certain amount of CO2. When you buy food and goods, the production of the food and goods also emitted some quantities of CO2.

Trees absorb Carbon Dioxide from the atmosphere as part of their photosynthetic processes. It is the primary means of generating nutrition for its growth and repair activities. It is therefore acceptable to state that the quantity of carbon dioxide so absorbed is a direct function of the growth stage (young, mature or old tree), the specific species of the tree, the quantity of foliage (leaves), size of tree etc.

Given this context, the United Nations Environment Program (UNEP) as part of its ‘Billion Tree Campaign’ presents the following indicative figures: an average tree absorbs 12 kilograms (26 pounds) of CO2 and emits enough oxygen for a family of four for a year. 

Assuming an average life-span of 20 years for a tree (accounting for tree-planting mortality rates etc.), no2co2 uses a figure of 240 kgs (or approximately 0.25 tons) of CO2 Equivalents (CO2e) as the Carbon Absorption capacity of a tree over its lifetime. Thus, a Carbon Footprint of 1 ton of CO2e can be thought of as requiring the planting of approximately 4 trees to ‘Neutralise’ its impact. 

Your carbon footprint is the sum of all emissions of CO2 (carbon dioxide), which were induced by your activities in a given time frame. Usually a carbon footprint is calculated for the time period of a year.

Petrol 1 gallon (UK)

Each of the following activities add 1 kg of CO2 to your personal carbon footprint:
  • Travel by public transportation (train or bus) a distance of 10 to 12 km (6.5 to 7 miles)
  • Drive with your car a distance of 6 km or 3.75 miles (assuming 7.3 litres petrol per 100 km or 39 mpg)
  • Fly with a plane a distance of 2.2 km or 1.375 miles.
  • Operate your computer for 32 hours (60 Watt consumption assumed)
  • Production of 5 plastic bags
  • Production of 2 plastic bottles

Calculating Carbon Footprints

To remain as accessible as possible, most carbon calculators ask very simple questions about consumption. To determine the amount of CO2 produced by home electricity, the calculator divides the estimated or exact usage by the price of power in the area. The calculator then multiplies this number by the state's emissions factor, a figure that relates to the type of energy the state uses. Calculators also factor in natural gas, heating oil and propane use. Carbon footprints also include the CO2 produced by transportation. Most people don't know their annual fuel usage, so calculators usually ask for an estimated annual mileage and the car's make, model and year. After compiling all the figures, the calculator produces a total CO2 output in tons -- a carbon footprint.

What are carbon credits?

One carbon credit is equivalent to one tonne of CO2 emissions. Credits can be sold in the international market at the prevailing prices via certain credit exchanges. Formalised in the Kyoto Protocol, carbon credits help developing/ underdeveloped countries as they traditionally have lower per-capita carbon emissions than developed countries and will need to emit CO2 owing to increasing industrial growth. At this point though, these countries can sell their carbon credits to other countries and reap the economic benefits of not polluting the planet.
A carbon credit (often called a carbon offset) is a financial instrument that represents a tonne of CO2 (carbon dioxide) or CO2e (carbon dioxide equivalent gases) removed or reduced from the atmosphere from an emission reduction project, which can be used, by governments, industry or private individuals to offset damaging carbon emissions that they are generating.
Carbon credits are a part of international emission trading norms. They incentivise companies or countries that emit less carbon. The total annual emissions are capped and the market allocates a monetary value to any shortfall through trading. Businesses can exchange, buy or sell carbon credits in international markets at the prevailing market price.
India and China are likely to emerge as the biggest sellers and Europe is going to be the biggest buyers of carbon credits.
Last year global carbon credit trading was estimated at $5 billion, with India's contribution at around $1 billion. India is one of the countries that have 'credits' for emitting less carbon. India and China have surplus credit to offer to countries that have a deficit.
India, China and some other Asian countries have the advantage because they are developing countries. Any company, factories or farm owner in India can get linked to United Nations Framework Convention on Climate Change and know the 'standard' level of carbon emission allowed for its outfit or activity. The extent to which I am emitting less carbon (as per standard fixed by UNFCCC) I get credited in a developing country. This is called carbon credit.
Today, one tonne of carbon credit fetches around Euro 22. It is traded on the European Climate Exchange. Therefore, you emit one tonne less and you get Euro 22. Emit less and increase/add to your profit. The Indian government has not fixed any norms nor has it made it compulsory to reduce carbon emissions to a certain level. Only those Indian companies that meet the UNFCCC norms and take up new technologies will be entitled to sell carbon credits.
There are parameters set and detailed audit is done before you get the entitlement to sell the credit. In India, already 300 to 400 companies have carbon credits after meeting UNFCCC norms. Till MCX came along, these companies were not getting best-suited price. Some were getting Euro 15 and some were getting Euro 18 through bilateral agreements. When the contract expires in December, it is expected that prices will be firm up then.     Source:

The energy generation from modern renewable is similar to the nuclear generation in India. The availability of trained manpower, institutions and research facilities for nuclear power are significantly better than in the renewable field. There is a need to build capacity in renewable energy and to attract professionals from the mainstream science/ engineering disciplines. 

In the last few decades, the education system in most developing countries has been improved considerably, at least in urban areas. Primary and secondary schools are well established and gradually universities are opened up. 

India’s fossil fuel reserves are limited. The major proportion of the domestic oil consumption is based on imports. Hence the importance of development of alternative energy sources has been recognized by the government.

The rapid growth in this sector would require an extensive pool of competent manpower (knowledgeable and skilled) to design, install and maintain the RE systems. The RE sector in India is currently (2010) estimated to employ 3,50,000 people, which includes both direct and indirect employment. Manpower growth in short term (2015) and medium term (2020) – The global  employment in RE is expected to increase nine-fold to reach a figure of 20 million jobs by 2030, with biomass leading the growth at 59 % of total capacity followed by solar PV at 31% and wind. The higher growth rate in jobs (9 fold) vis-à-vis the installed capacity (4 fold) is on account of the larger contribution from the biomass sector, which is more man-power intensive than the other sectors (Source – Green Jobs – Towards decent work in a sustainable, low carbon world, UNEP / ILO/IOE/ITUC, Sep 2009).

Training and capacity building 
The installation, operation and maintenance of Renewable energy systems need specific skills and knowledge. To impart this skill and knowledge to those entering the sector as well as continuously upgrading them, there is a need for training and capacity building. Currently there is a shortage of RE trainers, who can offer this service to the industry.

Facilitate Capacity Building
a) Strengthen existing renewable energy institutions, create new institutions, centers of excellence based on meeting the R & D vision 
b) Establish India as a global hub for renewable energy training / research  to carry out research in India. 

Manpower Requirements - The manpower requirements for renewable energy sector can be classified based on the nature of jobs that they would perform. Figure 1 shows a listing of the typical functional areas required directly for renewable energy systems. Each of the functional areas would require different skills and may be performed by manpower employed by different institutions. For example the installation of solar PV systems may need technicians who have undergone a few weeks of training on solar PV. Siemens carried out a few training modules for technicians in India during 1995-96. In addition to these functional areas manpower would be required for financing renewables and for policy analysis and regulation.

The different institutions that are involved with renewable energy can be classified as given in above Figure.

In order to effectively make the transition from a fossil fuel driven energy system to the future renewable based energy systems, it is essential for India to focus on building capacity for manpower training, strengthening institutions and building infrastructure.
