Creating wonders at the Bottom of the Pyramid

The expression “bottom of the pyramid” was coined by C.K. Prahalad and Stuart Hall and refers to the potential market of four billion people in the developing countries living on less than $1,500 per year. They state it as follows:

“The real source of market promise is not the wealthy few in the developing world, or even the emerging middle-income consumers: It is the billions of aspiring poor who are joining the market economy for the first time.”



I found the topic quite interesting and welcomed the opportunity to contribute to a whitepaper on the subject. So after some weeks of discussion and sharing of examples on the platform I was wondering how I could best contribute to the topic. I decided that it could be interesting to look at the shared examples through the business model lens, which I explained in an earlier post (what is a business model). In this blog (which I am writing from Yaoundé, Cameroon) I will simply share an interesting business case for each of the nine business model blocks I usually use to describe a business model. What I learned was that doing business at the bottom of the pyramid is really nothing else than real

There are examples of business model innovations in each building block. The most obvious is innovating in the value proposition. When mobile phones appeared in the market they offered a completely different value proposition than fixed line phones. In developing countries where fixed telecom infrastructure is weak and waiting lists for phone lines unbelievably long, mobile services were destined to thrive. In Nigeria MTN, a South African Telco set up a successful venture to tap into the 130 million person market.

Regarding target customer segments and distribution channels, Arvind Mills Ruf n Tuf Jeans (www.arvindmills.com) is a particularly interesting case. The entrepreneur Arvind Mills saw a niche market in stylish jeans at an affordable price that was not being filled by any company. Target customers are Indians who cannot afford conventional jeans but still wish to purchase them. So Ruf n Tuf offers a jeans kit at $6/pair to local tailors who function as a distribution channel to reach the final local customers. Due to the large scale Arvind Mills manages to make a profit on the low margins per jeans.

Anand Milk Union Limited (www.amul.com) is an interesting case of how a business innovation can change the fortunes of the poor in a developing country like India by integrating local skills and local activities into its business model. India was a country with milk shortfall and imported milk every year in form of milk powder. Then AMUL built up a huge milk industry from scratch together with local farmers. Today India is the world’s largest milk producer and it even exports milk. AMUL products are found on the shelves of Walmart in the USA and many other retail giants in the world.

A nice example of how partnerships can lead to BOP success is the case of GrameenPhone (www.grameenphone.com) in Bangladesh. Its founder, Iqbal Quadir, realized that if a woman could be given a micro-credit to buy a cow and sell milk then the same could be done for phone services. GrameenPhone was born. Supported by the multinational company Telenor he bought a mobile network license and set up a mobile phone network. Then he partnered with Grameen Bank, an established micro-credit institution in Bangladesh who brought in the knowledge on credits and a database of potential customers. The bank started offering women in villages a credit to buy mobile phones, which they used to sell phone calls to the villagers, repay their debts and make a daily living. Grameen Bank expanded its lending and GrameenPhone harvested a network of women reselling phone calls through their network.

Hindustan Lever Limited (www.hll.com) has been able to create new revenue streams by being proactively engaged in rural development in India for nearly 30 years. It set up Project Shakti (www.hllshakti.com) in 2001 with the objective of creating income-generating capabilities for underprivileged rural women, by providing a sustainable micro enterprise opportunity, and improving rural living standards through health and hygiene awareness. With working capital provided by HLL, Shakti women entrepreneurs sell HLL products to their local village. This gives HLL access to large markets that would not otherwise be easily accessible. 70% of the Indian population lives in villages, of which there are around 627,000.

Regarding the cost structures of BOP business models there is often a huge pressure to produce extremely efficiently, because products usually have to be cheap enough for Tier 4 customers. In general BOP cost structures are kept low by selling very large volumes and thus profiting from economies of scale. In addition many of the BOP business models described above make use of affiliation and entrepreneurship to shift parts of the costs to other partners in the business model. GrameenPhone, Arvind Mills and Project Shakti are just three examples of how tapping into local entrepreneurship by promoting micro business ownership can give access to powerful free distribution networks of incredible reach. This could have never been achieved by the companies themselves

Teach India-Right to Education is Light to Education!



Accelerating progres
s towards education for all is one of the defining development challenges of the early twenty-first century. In recent context of India, approval of Right to Education Bill is a very important step towards the dream of the developed Nation. Prospects for achieving equal opportunity and accessibility to basic education will definitely influenced by this bill. Like any human right, this right should also be protected and extended as an end in itself.

In other aspects of education, prospectus for reducing poverty, narrowing extreme inequalities and improving public health are also heavily influenced by what happens in education. Accessibility to basic information and knowledge through basic education is one of the most important conditions for overcoming social injustice and reducing social disparities in any country. It is also a condition for strengthening economic growth and efficiency: no country can afford the inefficiencies that arise when people are denied opportunities for education because they are poor, female or members of a particular social group. Some benefits of education are less tangible and harder to quantify than others.

People denied an opportunity for achieving literacy and wider education skills are less equipped to participate in societies and influence decisions that affect their lives. That is why broad-based education is one of the foundations for democracy and government accountability, and why it is such a vital input for informed public debate in areas such as environmental sustainability and climate change that will have a bearing on the well-being of future generations.

The impact of education is strongly conditioned by other factors, from macroeconomic and labour market conditions to the state of public health provision and levels of inequality based on wealth, gender and other factors. The benefits of education are likely to be greatest in contexts marked by broad-based economic growth, a strong political commitment to poverty reduction, high levels of equity in access to basic services, and a commitment to democratic and accountable governance.

Opportunities can strengthen economic growth by raising productivity, supporting innovation and facilitating the adoption of new technology. And broad-based access to good quality basic education is one of the foundations for broad-based growth, since it enables poor households to increase their productivity and secure a greater stake in national prosperity.

The ultimate goal of education is to equip children with the knowledge, skills and opportunities they need to realize their potential and to participate in social and political life.

Photovoltaics-Solar Enery Generation

Photovoltaic (PV) systems convert the sun’s energy into direct current (DC) electricity and then alternate current (AC), which is used to run your home’s appliances.  PV technology is both innovative and sustainable with its use of the sun’s abundant source of energy

Environmental Impact

PV and solar thermal devices are essentially specialized formations of glass, steel, aluminum, and plastics; their manufacture is comparable to that involved in making household windows, water heaters, or mirrors. The energy payback of a PV system (the point where it produces as much energy as it took to be produced) is about 3 years.

PV devices are essentially "electric glass" - their (usually) silicon substrate is a close relative of window glass, and the processes used to render it electrically reactive are the same as are used in the microchip manufacturing industry.   Some hazardous materials are used to produce PV.  PV systems also contain certain toxic materials such as cadmium and selenium.  However, these toxic materials are minimal compared with conventional energy sources.  Research is being done to determine the best way to recycle PV systems at the end of their lifetime.   Over its life, a typical residential system will avoid 124,300 lbs. of coal or 8,800 gallons of oil or 13.5 illion cubic feet of natural gas used in power production, and reduce NOx emissions by more than 1.5 pounds for each megwatt-hour produced.

FAQs (Frequently Asked Questions) 

  • Would a PV system work at my house?
  • How do PVs function in inclement weather?
  • How do I size my PV system?
  • How much energy do PV produce and how long do they last?
  • Do I need special permitting?
  • What maintenance is required?
  • What financial incentives are available?
  • How do I sell excess energy back to the utility grid?

Would a PV system work at my house?
PV easily fit on unobstructed roofs of most homes, depending on the size of your system.  Arrays are also mounted on the ground, if your roof can’t accommodate them.  Your roof must be in good condition and unshaded.  Panels are mounted at optimum angle and facing south (or north if you live south of the equator) to capture the greatest amount of sunlight, with variations up to 45 degrees.  If you live in an area with a great deal of insolation (sunshine) the PV will perform better. The map below shows the greatest areas of sunlight exposure in the U.S. (the red area of the map below receives the greatest amount of insolation).   If you live in a less exposed area, ask a local PV supplier for a solar site analysis to see if a system would meet your energy needs.

Remember, solar cells operate on sunlight, not heat.  Photovoltaics are even used in antarctica quickly melting any fallen snow on the glass.

How do Photovoltaics function in inclement weather?
Even during cloudy days, PV produce up to 80% of their maximum energy.  On an extremely overcast day, a system produces up to 25% of its potential energy.  Manufacturers test solar cells for year round weather conditions including high wind, hail, freezing, and thawing.  Some PV produce enough excess power during the summer to supply energy needs in the winter.  Sleet and hail rarely harm the panels and the panel efficiency may actually improve in cooler weather.  See Success Stories below.

How do I size my Photovoltaic system? 
The size of your systems depends on several factors.  Talk to a system designer or contractor to determine size factors such as:

  • How much electricity, heat, and hot water you use
  • The amount of sunshine in your climate
  • How much you want to invest

First consider what percent of your home’s energy you’d like the PV to supply.  For systems not connected to the utility grid (stand-alone systems), determine an accurate amount of energy output.  You may also add more modules in the future but must size the inverter and other equipment (such as storage batteries if off grid) for the expansion.

How much energy do Photovoltaics produce and how long do they last?
Electricity production depends on sunlight exposure, and how well PV can convert the sun’s energy.  At average exposure and efficiency, a PV system produces 1,800 kWh a year per an optimum output of 1 kW.  Typical PV residential systems are between 5 and 10 kW.  Compare this to the average energy use of an American home: 1,000 kWh per month.

PV systems should last over 20 years.  Most manufacturers guarantee their products for up to 25 years, with silicon based PV loosing efficiency at less than 1% per year.

Do I need special permitting?
Regulations on the who, what, and how of installation vary with location.  Installing PV usually requires an electrical license, and there may be codes or limits on the following:

  • Type of system
  • Installer’s level of certification
  • Electrical installation
  • Building codes
  • Connection to a utility grid
  • Eligibility for rebates and tax credits

Standards are set by the following groups:

  • Home owners’ association
  • Local government building department
  • Utility company

Talk to officials of your local government or state energy office for details on regulations in your area.

What maintenance is required?
The expected life of the PV modules is between 20-25 years.  Maintenance costs are fairly low since you can check the system periodically on your own.  Your PV system may only need check-ups on the condition of solar cells, battery, and electrical connections.  The biggest expected maintenance expense is for the inverter, which has an expected life of about 8-10 years.  The inverter is the gizmo that converts the DC power of the cells to the AC power your home and utility uses.  The cost for replacement can be as high as $8,000 though those costs are also coming down.  You should hire a professional to do any major repairs.

What financial incentives are available? 
Depending on where you live, these incentives may be available:

  • Property tax exemptions
  • Sales tax exemptions
  • Tax credits and deductions
  • Renewable Energy Certificates (credits paid to the energy producer)
  • Rebates
  • Grants
  • Loans
  • Bonds
  • Mortgages

 These incentives may be offered through the following providers:

  • Federal government
  • State government
  • Local government
  • Utility

Contact the energy office in your state or province, or your local utility for more information.

How do I sell excess energy back to the utility?
If your PV system is connected to a utility grid (grid-tied system), and produces more energy than your home uses, utility companies buy backthe excess power.  This buy back is called Net Metering or a Feed-In-Tariff.  During times of excess energy, such as a sunny, summer day, the inverter converts electricity to the utility’s standards, allowing the company to purchase the energy as it flows backwards through your meter.  Currently, only 39 states allow connection of PV to the grid, and only 36 states require net metering for utility companies.  Ask your utility company about local polices.  A customer may use power from the utility during the night or on a cloudy day.  At the end of the month or year, the electricity bill shows whether the PV system produced more or less energy than the customer used.

Installing a Photovoltaic System
Self Installation
The U.S. Department of Energy advises hiring a contractor instead of installing a PV system yourself.  Professional installment ensures a functional system, a guaranteed warranty, safety, and protection of your home appliances. Search for photovoltaic distributors on this web site.

Finding Contractors
For design, installation, and maintenance, search for a supplier on this web site.  Solar vendors and installers range from large corporations, small businesses, discount warehouses, or mail order companies.     

Choosing a Contractor
When you talk to a professional, ask about their experience, licensing, recent training, and level of certification in PV systems.  Find an installer whose professional relationship with the local inspector is reputable.  Consider liability insurance with your contractor and ask about repair and maintenance.
Ask about products the contractor uses: Do they meet industry standards?  Are warranties available?  Talk to the installer’s business references and former clients about their experience, and the current condition of their PV system.

Success Stories
This Massachusetts home has used 40 square meters of PV since 1980.  Mounted on the south roof, this system generates more electricity than the house uses during the summer.  The excess electricity sold back to the grid during the summer covers almost the entire cost of energy during the winter.

Also in Massachusetts, a 26 unit condominium is opening in Brockton that features a PV system for each unit.  Residents will have their own 18 panel PV system and save $600 per year.  Designers expect each system to generate 4,212 kWh per year, over 60% of the electricity needed for each town home.  This six million dollar project also includes rainwater collection tanks, and energy star ® and LEED® certification.  A $458,300 grant from the Renewable Energy Trust helped finance the cost of panels and installation.
