This page serves to document composition and prices of solar home systems around the world. Please feel free to add your project to this page.
For an evaluation of these economic data, information on the quality and sustainability of the SHS, as well as on O&M and services has to be collected. In addition, it has to be checked to what extent the target group of the poorer rural population could be reached within the different projects.[1]
Assuming that the solar panel lasts 10 years, the battery five years and all the lamps are changed after five years as well, the total system costs about 34 ETB (1,89 €) per month over a period of ten years. Regular maintenance costs and possible change of cables and fitting are not considered in this example, but compared to monthly expenses on kerosene and dry cell batteries, the price is quite low. Even if the battery was changed three times within ten years, the monthly cost would only be 39 ETB (2,17 €, September, 2009), still less than the amount usually spent on kerosene. This is of course no detailed analysis. In reality, other influencing factors have to be considered: market prices change, the LED lights might be changed more often or even not be change at all, etc. Regular maintenance costs and possible change of cables and fitting have to be considered as well. Even so it can be seen that SHS have the potential to be a competitive alternative to kerosene and dry cell batteries. However, it has to be kept in mind that SHS owners still spend money on kerosene and dry cell batteries, so that monthly energy expenditures might even rise. Down payment for the SHS installation and monthly loan repayment might be an obstacle for poorer households, that could prefer to buy batteries or kerosene on an irregular basis, whenever their financial situation allows it.
In his diploma thesis "Electricity and Sustainable Development: Impacts of Solar Home Systems in Rural Bangladesh" Michael Blunck shows that the expenditures on a SHS for lighting purposes exceed those on kerosene even over a period of twenty years. The initial installments costs and accumumaltive monthly loan repayments are usually far higher than expenses on kerosene for lamps. The household survey conducted in 2006 revealed that in most cases overall expenses on the SHS would not amortise over a period of twenty years. Households without a SHS would have average accumulative lighting expenditures of 29,040 BDT whereas households with a SHS would have expenditures of 50,670 BDT.
