Solar pv panels will often produce more energy than you can use in a day and without a solar battery your surplus will be sent to the national grid.
Connect solar panel to immersion heater.
However you may not be aware that there is a gadget which enables you to keep this surplus energy use it to power your immersion heater reduce your electricity bills even further and still.
Using immersion heater for water tanks will ensure that after the water is heated by either by solar or the regular power source it can be stored in insulated storage tanks for later use.
Once it detects that electricity is being exported it diverts the electricity to the immersion heater to heat the water.
How to heat water with solar panels add an optional thermostat you can use a solar panel to make hot water or to keep water from freezing.
Modulation based solar pv surplus energy manager that monitors in house usage and pv power production to divert almost all the available surplus power to the immersion heater to heat water.
All solar pv optimisers involve clipping a sensor on to electrical cables that can accurately determine in real time whether electricity is being used or exported.
This would work better as the load would vary with voltage and the voltage would vary with the amount of sunlight.
Installers can check the roof to see if it can support the panels.
They can also look at shading and other factors that might impact efficiency.
There are many advantages to using a solar water heating system and many of the disadvantages can be averted through professional installation.
Simply wire the solar panel directly to the dc water heating element or through a thermostat to regulate the water temperature.
Its intelligent sensing technology prevents the export of surplus power to the grid for negligible returns and uses it for local consumption meaning you.
How do solar pv optimisers link solar pv and immersion heaters.
Getting the most out of a solar water heater.
You could in fact just connect the panels directly to the immersion heater supplying it with dc from the panels.
