The theme of my thesis is electricity supply for a farm, which is far from communal network.
The system, which I plan is a hybrid system, because I wanted enough energy for the farm, independently from weather whimsicality. After I chose the parts of the system, I counted the investment expense, also look at the cost of the connection to the electricity-network. I feel self-sufficiency with renewable energy sources is an interesting topic, especially when the use of fossil energy is rising.
Prospective in near future we can use alternative power source with more and more efficiency. To my mind it is very important to watch the developing technologies, to create better energy supply.
