The Advantages of PV Water Heating

Solar electric (PV) water heating has several advantages over solar thermal heating. PV could provide the answer to your water heating problems and this is why:

  • PV is easier to install than traditional thermal solar. The main reason for this is that the water does not need to be pumped up to the pressure-tested rooftop tanks for heating to occur.

  • PV uses less space than solar thermal heaters because there is only one tank needed for operation. This reduced space consumption makes it a more viable option for many homeowners.
  • PV requires far less maintenance. Solar panels need to be checked by a professional on a yearly basis, but PV will survive without this excess care.
  • As there is no additional tank there is not a problem with scale build-up in PV heaters either. This means that the system will require less maintenance.
  • PV can be used to create energy for the grid when the water is hot enough. During peak sunlight hours this means that the system is still working efficiently.
