Good work in the analysis of cost. I actually have this friend @olajidekehinde who researched the effects of irradiance and temperature on the current output of the solar panel for his final year project. And he employed the newton-raphson method of solving non-linear, non-homogeneous differential equation to develop a model. some interesting stuff.
He also does a lot of solar posts and installs the entire solar inverter ststem for clients. I really enjoy reading this anyways. So, do you do installations, or you just researched the BEME?
I've read his articles and commented on a few. I'm a huge fan of renewable energy, so I understand how it works. This is not solely based in research. Newton-Raphson finds a lot of application in power system engineering calculation. Thank you.
