Solar iBoost – Hot water solutions

Solar iBoost is a new innovative product designed to optimise the excess solar energy created from your PV installation.

Solar iBoost allows you to use excess power that you would normally export to the grid to:-

  • Cut the cost of heating your hot water and
  • Reduce the use of your boiler.
Solar iBoost uses ONLY surplus photovoltaic energy generated that would usually be exported, unlike some similar products.
If you have a hot water tank with an immersion heater, the Solar iBoost can increase the return on investment of your solar panel system.  The export rate for electricity is lower than the cost of purchasing electricity from your energy provider. It therefore makes sense to consume as much of your generated energy as possible.
The Solar iBoost is ideal if you are out of your home a lot during the day, especially in the summertime. Alternatively if you have a large solar array and little energy usage.
During the winter, the iBoost will pre-heat your water with any excess PV energy generated. This means you can save throughout the year.

How Solar iBoost works.

The system works with wireless receptors, creating a no mess, no fuss installation.

The Sender has a clamp which monitors if electricity is being fed back to the grid or not. You may be at home and, for example, only be using 20-30% of the energy produced by the PV array. This information is picked up and transmitted to the Solar iBoost. It cleverly knows just how much energy to release to the immersion. Even a steady flow of just 200W to the immersion will start to raise the temperature and save you money.


Typical savings example:-

 In a household with a PV array generating a 2kW surplus, just 2.5 hours is needed to raise a 100ltr tank temperature from 20 to 60 ̊ C. This provides you with a saving of approximately £0.50 per day.            (based on average energy prices).   June 2014
