How to set up a solar water heating system？

I did not find solar heating in the case of simscape, it was only photovoltaic power generation.

Hi @忠宇

If there is no pre-existing model available for the thermal dynamics of a solar heating system, it is possible to manually derive the governing differential equations.

Could you please provide the relevant excerpts or references from solar energy textbooks or engineering handbooks that detail the applicable differential equations? Having access to those source materials would allow me to provide a more informed and comprehensive response.

%% Solar heating system
function dT = solarHeating(t, T)
    % parameters
    param1 = ...;
    param2 = ...;
    param3 = ...;
    
    % differential equation
    dT  = [eqn1;
           eqn2];
end

But solar energy varies according to the weather in the region, can this also be done in simscape or with m files

There are journal papers detailing how to model the Solar Irradiance. They are mathematical equations though.
