1: of direct costs for the system and for installation, without O&M.
2: for private costumers, social infrastracture is subsidised with up to 85% of costs.
3: but refinancing loans at discounted rates
For an evaluation of these economic data, information on the quallity 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.

The Solar Energy Foundation, Ethiopia
The Solar Energy Foundation (Stiftung Solarenergie) has developed a small solar-home-system (SHS) with a 10 Wp PV module for rural electrification in Ethiopia.
Each SHS costs 3000 ETB (about 167 €, September 2009), including manufacturing and installation, divided approximately:
| 10 Wp PV module | 15% | 450 ETB | 25 € |
| 18 Ah gel-type lead-acid battery | 20% | 600 ETB | 33 € |
| Charge controller with payment function and data logger | 25% | 750 ETB | 42 € |
| Lamps | 15% | 450 ETB | 25 € |
| Cable, box, plugs, user book, fixings, manufacturing, installation | 25% | 750 ETB | 42 € |
The capital cost of the systems installed in Rema and its neighbouring village of Rema ena Dire were financed by donor funds. However, households must pay a monthly fee of between 10 and 14 ETB (0,66 € and 0,78 € (September, 2009) depending on the number of lamps in their system. The charge is divided into two parts: a basic fee which is used to pay the local technicians for regular maintenance work, and a further fee to pay for replacement parts such as the battery and LEDs.
