Tiivistelmä
The purpose of this thesis was to design a photovoltaic (PV) systems for a warehouse building situated in Nakkila and investigate possible methods to increase self-consumption. The thesis includes a feasibility study and different options presented to the client.
Average daily production, of different system sizes, and average daily consumption) were compared only for the summer months and eventually the surplus power was estimated. Two suitable power output were identified, 3kW and 4kW system.
The former was designed as a simple system with a main criteria of producing minimal surplus energy, while the latter was conceived as a bigger system and coupled with recovery system for the surplus energy. The extra energy will be converted into hot water using a 1-phase switch controller connected to a coil.
The results show that both systems are a valuable investment.
A first installation will be done up to 3kWp with a 4kW inverter. In the future the PV system will be upgrade to 4kWp. The oil burner will be substitute with a 100L water tank and a solar controller switch will be used to reroute the surplus production to the tank.
