• researching and doing the theory

  At this stage of the project I'm still working out the logistics and researching the relevant topics of the projects through research papers and small experimentation, 

  Also looking at the relevant efficiency equations for a basic solar panel so I can compare my results with ones on the market for the same price, 

  and when looking at the theoretical power output I had to look at the theoretical losses like:

  1. shadow losses
  2. temperature losses
  3. DC cable losses 
  4. AC cable losses
  5. inverter losses
  6. losses due to dust and obstructions

  ---

  the other equations I looked at was for maximum output:
  

  where:

  KWp = norminal rated maximum

  n = the models 

  , the average energy produced per year:

  where:

  Ema = available solar radiation(depending on weather conditions)

  n(eta) = efficiency of the cell

  ,the temp of the panel itself (because the efficiency changes based on operating temp):

  where: 

  nt(eta t) = over all system

  Y(gamma) = temp coeffient
