   Do you really mean PV with gas boost? I think your options are PV/heatpump or solar thermal/gas boost. I would take the PV heatpump option as long as you had good solar access and could install an array of 5kW or more. Good heat pumps like the sanden appear pretty reliable these days and collecting PV power is more useful than thermal collection on most cases as you can use the electricity for other things when the water is hot enough.

   Hi
   I live in south west Au
   So not blazing sun
   Not sure which is more efficient/ economical
   Your suggestion is the heat pump with approx 5 kw solar panels installed

   Solar panels with solar panels
   Or the gas booster with solar panels
   And the cost to purchase
