Is a Solar Power Diverter the better option?

While solar batteries are one way to store and make use of the excess energy generated by your solar panels, they’re not the only solution. Solar power diverters allow your heating system to benefit from solar energy, which means that your boiler won’t have to work so much and you could be on your way towardsfree hot water.Plus, they don’t tend to be as expensive as solar batteries.

太阳能分流监测的能量being generated by the solar panels and how much is being used around the home. When there’s more energy being generated than used the solar power diverter will divert surplus energy to an immersion heater in the hot water tank, which means that the water in the cylinder gets heated with free energy. This will continue to happen until another appliance around the home needs the energy.

While the benefits of solar power diverters and solar batteries are similar:

  • Reduced energy bills
  • Use more of the energy being generated by your solar panels
  • Less reliance on your energy supplier

Each has their own unique benefit, with solar power diverters offering the possibility of free hot water, while solar batteries store free energy to use during the evening and at night.
