A PV solar hot water diverter utilizes surplus electricity generated by solar PV panels to heat water, providing an efficient and sustainable way to meet hot water needs while reducing energy costs and carbon emissions.

A PV (photovoltaic) solar hot water diverter combines solar PV panels with a hot water diverter system to efficiently utilize solar energy for heating water.

Here's a detailed explanation of how it works:

Hot Water Diverter System:

In addition to generating electricity, the solar PV panels can be where applicable, connected to a hot water diverter system. This system includes a diverter controller and a pump or valve that diverts excess electricity generated by the PV panels to a heating element in a hot water storage tank or cylinder.

Diverter Controller:

The diverter controller continuously monitors the electricity production from the PV panels and the hot water demand in the building. When there is surplus electricity generated by the PV panels and the hot water demand is present, the diverter controller activates the pump or valve to divert the excess electricity to the heating element.

Heating Element Operation:

The diverted electricity powers the heating element, which heats the water in the hot water storage tank or cylinder. This process effectively utilizes excess solar electricity to heat water, maximizing the use of renewable energy and reducing the reliance on conventional heating methods.

Optimization and Efficiency:

The diverter controller optimizes the operation of the system to ensure that excess solar electricity is used to heat water whenever possible. It may adjust the flow of electricity to the heating element based on factors such as the intensity of sunlight, electricity production from the PV panels, and hot water demand.

Backup Heating System:

In situations where there is insufficient solar electricity to meet the hot water demand or during periods of high hot water consumption, a backup heating system, such as an electric immersion heater or gas boiler, can be used to supplement the solar heating.
