	*To connect to existing system - 300 Euro for tower/guy wires/concrete if necessary if no big rocks. 100Euro for cable. Diversion charge controller - goes to a resistor if too much - 250 euro - and resistor is $250 euro. Resistor is a thin wire wound around a metal cylinder for good heat dissipation. Surge power of 1kW of resistor.		*To connect to existing system - 300 Euro for tower/guy wires/concrete if necessary if no big rocks. 100Euro for cable.
