Solar Home System (SHS) is the economical and most feasible for poor villagers in rural areas. However, the villagers can use very limited power from SHS.
PV Hybrid Mini/Micro Grid can supply more power (kW) than SHS and it can supply for the whole day. But, there may be challenges for management, maintenance and financial issues.
For villages, the SHS may be the best solution of the lack of electricity distribution subsystem(s). The nature of the housing, activity, land topological constraints are the main reasons of the mentioned recommendation. For better utilisation of the solar energy, the thermal loads can be partially or totally supplied from simple solar thermal systems, while the essential electic loads are to be supplied from the solar-PV. Energy saving, and energy efficiency awareness programs may be also adopted for maximisation of the usefulness of the enegy utilisation.
Hello Prof Mohamed EL-Shimy,
Thank you so much for your good answer.
Yes, of course, for using the small load appliances such as lighting loads, mobile phone charging, portable DVD player, SHS is the feasible and most common option in Off-Grid Rural Loads.
The big problem of SHS is very limited power.
Also, there are challenges like short lifetime of the controllers, inverters and the batteries due to low qualities of the products and lack of the awareness of the local community.
So, I deeply agree about your message in your answer, "Awareness Programs" in rural areas.
If the village needs more powers for rural industrial productions, PV Mini/Micro-Grids are the good options.
Sincerely,

Well, answer depends upon the system in which these two options are to be used. For the rural areas where grid connectivity is not available, the standalone PV system is the most suitable. Though it has a limited power backup capacity, it is more reliable as the single home in the farthest rural areas has low demand.
The grid connected hybrid PV micro/mini grid may be the costlier and it demands the grid availability in those areas.
Hello Prof Patel,
Thank you so much for your good answer.
Sincerely,
Prof. Ze Ya
It depends on location and demand profile.
Mini-grids have more socio-economic developmental potentials over SHS, with power uses for productive applications.
