Bringing Affordable Solar Lighting to Millions

Posted: 02/24/2012 12:05 pm

Sometimes great technology companies are about creating things that people never even imagined that they needed or wanted -- look at Apple and Facebook. But sometimes, great technology companies are about taking a very simple product and making it affordable and available to people who wouldn't normally have access to it.

That's what Ned Tozen and his co-founders at d.light have done with their simple, easy to use, affordable solar paneled lighting that is being used in countries where electricity is hard to come by.

There are 1.6 billion people in the world who don't have access to electricity. There are an additional one billion people who have some kind of electrical connection but "it's so intermittent that more than half the time they are off the grid."

Many of these people are using kerosene for lights. It's a terrible source -- hazardous, dim, polluting, and expensive. Many people around the world spend 10 or 20 percent of their income just to buy kerosene.

Ned and some classmates were grad students at Stanford. In 2006, they took a class called "Design for Extreme Affordability" at Stanford's Design School (it's an amazing place that I was fortunate enough to attend for a few days during an Executive Education program on Social Entrepreneurship). It was an interdisciplinary class with students from the engineering and business schools. As Ned told me, the class was filled with people who are "passionate about social enterprise thinking about how to develop technology for 'base of the pyramid families' families making less than $2 a day."

Their team wanted to come up with some ideas of how to address the needs of people who don't have access to electricity. So, as part of the class, they went to Southeast Asia to see for themselves. They soon realized there was a real need that wasn't being met and they started brainstorming solutions using the Design School's unique method of product design.

Soon, the idea became more than just a school project. The Design School incubated the team -- giving them space and some funding to get started.

They certainly didn't come up with the idea of solar lighting replacing kerosene. The idea had been around for a while. And, solar has been getting a lot of buzz lately. But most of the companies offering solar solutions don't see the 1.6 billion people as a real market. For a variety of reasons, including the problem of distribution -- not too many large companies were interested in finding ways to get products to "the bottom of the pyramid." There was a lot more lower hanging fruit for these companies to go after. They just didn't look at this as a viable market for them.

Ned and his team were able to address a lot of the challenges to making products work for this market.

The biggest challenge was that products had to be extremely robust. According to Ned, "Most of the existing products couldn't hold up in these types of environments." Plus the customers are extremely price sensitive and there wasn't really organized distribution.

Of course, the product had to be as affordable as possible.

The team looked at multiple options -- should they be a non-profit or a for-profit business? In the end, they decided that "the way to achieve the best social impact is to create a business that is sustainable and scalable where it's not funded with grant money but can be funded with the profits of the business."

So, d.light went out to investors instead of foundations and raised money from several well-known investors including the always innovative Acumen Fund, Draper Fisher Jurvetson and others.

Today, over five million people are using the product, and there is distribution in 40 countries in India, parts of Africa and Asia.

They have partnered with Kopernik to reach people in places where they don't have distribution yet. Kopernik also has an interesting model, connecting affordable technologies with communities that don't have access to them. They are trying to set up sustainable marketing and distribution channels in places like East Timor.

The product cost somewhere between $8 to $10 for the light -- which may seem like a lot for people living on less than $100 a month. But, according to Ned, "People are spending on average $5 to $10 a month on kerosene. So, the economic payback is so fast for people they are willing and able to make that investment."

It wasn't an easy road. According to Ned, "It took a few years of getting the product and distribution right, hitting our head against the wall, but the last couple of years we've seen an amazing explosion in the market."

"We didn't imagine where this all would take us when we got started... We had big dreams when we started out and thought that we could make a big impact, but actually seeing it happen --that's been a different experience than just imagining it. It's been really amazing."

We need cheap solar panels all over the world. However Big Oil and Coal will not allow it to happen in some countries. Here in the US?!? It is nice that other countries can use this technology but here it will always be expensive because of Big Oil and Big Coal!

Solar works. It is clean and renewable where the sun shines adequately.

It just needs a bit more incentivization to break into the energy market.

In parts of developing world as much as 30% of distributed electricity is stolen. There should be ways of promoting solar devices and at the same time reducing theft.

You could run a lantern on an ethanol blend also. Solar lighting is nice, but battery storage capacity and the unavailability of sunlight at night-time is...still something of a hassle. Solar-thermal, there's a way to store a fair amount of energy and distribute it via grid resources. But, maybe also visiting some Victorian-era DC technology for simple applications such as home lighting, might be worth some study. Solar panel output is typically measured in DC at small amperages.

Solar is currently very competitive if net metered or tied into the gird. Peak use is commonly udring the day, particularly for business needs. Grid tie in removes the need for battery or other energy storage.

For example, from an American energy policy approach....think large roof space in hot, sunny areas where solar cells could be installed that is then tied into the grid. Every WalMart or large, big box store where there is at least 6 hours of good sun exposure should have to offset their energy needs as part of NEPA assessment.

For off the gird, batteries are needed. And marrying a small solar to a wind turbine is nice. When the sun is not out, it is often stormy or cloudy and windy. Reductions in battery needs occurs when the user minimizes their demand.

When government is interested and encourages use of solar, people answer.
That's why countries like Spain and Israel are at the forefront of solar use and innovation,
China is also making a significant investment in solar capacities.
In Israel for instance, close to 95% of all apartment buildings use solar for water heating.
Surely, sunny states like California, Texas and Arizona should have the same. The benefits are tremendous .

Nice. We need such innovation both here and abroad. If we can find a way to meet needs in a more sustainable way and give people hope, then we shall be improving the world -- doing what we ought to be doing.

Thank you Ms Hamburg,

This is a topic that is too often over looked by most people and we should seriously reconsider our thoughts on SOLAR POWER as an alternative source for electricity.

I have always been fascinated by the fact that we can have FREE electric if only we could purchase the hardware/equipment to make it happen.

Until just recently the average citizen couldn’t afford the equipment but it’s becoming more and more affordable all the time.

I will begin experimenting with solar power in the next few months simply because of the ever rising cost of gas and electricity.

Everything we buy is affected by the cost of oil and if we stop with the glutinous dependency we could bring the costs down to a minimum.

We can’t totally break free of oil but we can make a huge difference in how much we use and this story should be enough to inspire more people to consider it.

Thank you and have a wonderful day.

Our Military has been in the forefront in developing alternative energy sources. Sadly for them their efforts to develop solar alternatives to kerosene run afoul of their most ardent backers in the right-wing political world of climate science denying real world K Street lobbyists.

Another group also looking to solar to solve a problem are the folks behind the 'solar suitcase', which is basically designed to provide the light and power for an obstrestics care unit.

Here's how I heard about it

That’s not a problem.
We can always use Nickel Cadmium Batteries.
They’re more expensive but they last a lot longer anyway.

Most Golf Carts have them now days.

meanwhile a teenager in Nepal developed a solar panel using human hair in place of silicon:

we need to get people educated around the world because we never know where the next breakthrough will come from - this kid is one of VERY few in his area who was able to get an education - who knows what other incredible inventions are lying nascent in his neighbors?
