S-F, the first step to going solar is to reduce your electrical usage. Investing $1 in energy reduction saves $5 in energy generation.
(I'm assuming you're already saving, so that was for any n00bs that may stumble along.)
What kind of water heater do you have? On-demand or tank? Electric or gas? Switching to a tank and investing in a solar hot water set-up will be more efficient ($$$-wise) than PV.
