Problem is high voltage dc solid state relays are rare and if they do exists they cost a lot.
Do hot water solar panels create ac or dc.
The price of a suitable solar hot water system is about 4 000 installed.
A device called an inverter is required to convert the dc electricity from solar panels into appliance friendly ac.
Well not quite the first issue is the hot water heater s thermostat contacts are designed to handle ac loads only so we have to use a contactor ssr to switch the solar panels in and out.
If you are using an ac thermostat and you are putting dc through it to trigger the relay expect the thermostat to wear out prematurely catch fire or have the contacts of the thermostat weld together.
Good work and when the hot water gets too hot which probably never happens you have a thermostat and relay to disconnect the solar modules.
Such a system can also be designed for an ac motor of different power ratings which is available in the.
That s for a flat plate thermosiphon tank on roof style system like the one in the first pic above.
A solar hot water system will typically cut your water heating energy bills by 70 80.

A couple of my thoughts.
Direct current dc electricity is what solar panels produce and what batteries hold in storage while alternating current ac electricity is the type used on the grid and in most household devices.
The inverter by itself does not generate any power.
Even though solar panels produce dc power you could still use all of your normal 110v 120v 220v ac appliances by using an inverter.
Use a solar hot water system to heat the water directly.
An inverter is an electronic device that produces ac power as its output whenever dc power is provided at its input.
The electricity generated from solar panels is in the form of dc or direct current.
