Following some new analysis MV Solar has now switched to using the combination of a rooftop mounted Solar PV panels and an electric heat pump as our default solar hot water solution.

This brings MV Solar customers the lowest cost and most adaptable solar hot water system available which can even reduce summer air conditioning costs!

Hot water and air conditioning are two of the largest energy costs in your home.

Most people know about solar hot water systems that use a flat plate or evacuated tube collector to heat your water.

These systems have now been superseded by a new way of making hot water from the sun that saves on both your hot water and air conditioning bill.

Rather than producing hot water directly, PV solar panels on your roof turn sunlight into electricity which can then be used to make hot water using a highly efficient heat pump.

Heat pump hot water systems take heat out of the outside air and move it into your hot water tank.

Running your heat pump hot water system in the middle of the day on solar electricity is more efficient than using off peak electricity at night because the heat pump is drawing heat from the warm daytime air rather than the cooler air at night time.

Your tank heats faster and means that the fridge like noise from the heat pump isn’t around at night to disturb your sleep.

One of the great advantages of the solar PV with heat pump hot water system is that the tank heats very quickly during summer when the outside air temperature is higher and hot water use is less.

This means that in the hot afternoons of summer the energy from your solar panels can be used to save on running costs for your air conditioner.

It’s the hot water system that saves you money on cooling!

Our analysis shows that a Solar PV powered heat pump is the lowest cost hot water solution when both installation and running costs are taken into account.

It’s the only solution that pays you back over time by saving on air conditioning costs.
