  • Photo voltaic Powered Water Heater – heats up water;
  • Photo voltaic Powered Air Heater – heats up the air.

Now, you could not need to hear this:

Most residential photo voltaic firms is not going to inform you that different, extra environment friendly choices can be utilized as a substitute of PV photo voltaic panels. So as a substitute of specializing in photo voltaic electrical energy, it’s less expensive to put in photo voltaic house heating.
