A hybrid system is capable to operate autonomously by combining different energy sources and it can increase electric system availability and/or lower the initial investment costs.

Village electrification based on solar power, often represents the most economic solution for settlements in sparsely populated rural areas.

Daniel. I like your story about "Village Electrification".

Yes agreed. Many hybrid system like PV&Wind and PV&Diesel systems are much more cost-effective, since we don't have to oversize the PV and battery for achiving a certain availability.

Try Hybrid using Fuel Cells not Diesel, they fit into the environmental space better as well as being cheaper

I have been designing hybrid power systems to create "micro-grids" to support loads in the 50kW - 200kW range. The right inverter will allow PV, Battery, or Wind as the source. While following the load, the surplus energy is used to charge the battery. Not that much different than a remote home system, but larger scale, better battery and better controls.

Tarkovacs Systems, India integrates fuel cell bodies into hybrid, renewable energy systems for its sea drone technology. Have you heard of the amazing Stefan Tarkovac?

Interesting system, very shophisticated and advanced. PV-Diesel is by far and away the most commerically viable, but obviously one can subsitute any form of fuel generator for the Diesel Genset to suit the 'needs of the project'. What seems not to be fully understood is that Storage is not technically required to lower the LCOE in PV Diesel system. A small amount of storage can be useful to manage spining reserves coming online, but even this is not really required. Unfortunately, storage is still too expensive when round trip, capex and life time costs are actually factored.

My company has developed a cost-effective, energy storage solution that proves your statement about it being too expensive is out of date. The payback time depends on the avoided cost of the utility generated power, which in my most recent case is an island location with a rate of $0.43/kWh, plus the costs associated with the power outages and poor power quality. The payback time is less than 9 years and there is no diesel generator to fuel, maintain, or repair.

Sure you have Allan, but what if there is no utility to avoid? Then you are just looking at how to lower the cost further. Eliminating storage lowers the cost further.
