<p>Hi Benjamin,</p>
<p><br>
</p>
<p>Solar irradiance has the units of [kJ/hr.m^2], i.e. energy rate per unit square meter. It is quite likely that the magnitude of thermal energy yield (kJ) will exceed the integrated solar irradiance (kJ/m^2), if the surface area of your solar panels is greater
than 2-3 m^2, depending on the thermal efficiency of the panels. Make sure you have taken the units and area into account in your calculations.</p>

Dear all,</p>

<span lang="EN-US">During my project with the hybrid solar panel type 50b I found out some strange behaviour during the total yield measurements. The solar panels produce more thermal energy than irradiance they receive, can someone explain me how this is possible
and if maybe make a mistake somewhere.</span></p>
