Here in Greece my system cost around $600 plus $50 to hire the crane lorry to lift it onto the flat roof plus $100 for the plumber and his mate to install it. It's so efficient that in summer I have to cover half of the panel, otherwise the water boils and blows the pressure relief valve.
It includes an electric immersion heater, which we use occasionally on overcast winter days.
