Photovoltaic Lamps CDM Projects

Photovoltaic Lamp

Photovoltaic CDM Projects are feasible when poor households are not connected to the grid and they yearn to come out of darkness. The technology is to install a roof-top photovoltaic panel over each house and connect it to 3-5 LED/CFL Lamps. Though the primary objective is to provide lighting, these projects empower the End Users and have tremendous impact in terms of personal safety, schooling and education, pride and self respect.

Carbon Revenues

Typically, a photovoltaic lamp generates 0.1 tCO2-e per lamp per annum. At € 20 per CER and an exchange rate of ₹ 70 this translates to a carbon revenue of ₹ 140 per lamp each year of the 10 year long crediting period.

Since LED/CFL Lamps yield a little over 1 CER per lamp over a 10 year crediting period, revenue from the forward sale of CERs is just about enough to cover the cost of installing and maintaining the solar panel and 3-5 lamps, and replacing the battery once every 2-3 years.

Carbon revenues are not sufficient to cover administration and overhead costs for which the End Users have to make an annual contribution.


Project requirements are to secure carbon financing, negotiate and purchase inventory, transfer Items to the villages, record installations, and familiarise the families on daily usage and maintenance,. Implementation is fairly straightforward with a village cadre trained to install the hardware on each rooftop and later to perform basic repair and maintenance tasks. But since large volumes of expensive inventory is involved, stock movement and strict controls are vital.

Monitoring of Emission Reductions generated is calculated by counting the number of units/lamps not operational and deducting from the total installed.
