Solar Power System Update

For those following along with the solar power system. Today was the highest peak production day so far peaking at 2.5KW. Pretty good for a nominal 3kW system in the middle of winter at a non-ideal angle and not peak time of the day. Recent weather has been awful, but the system still produces usable energy on dark heavily overcast and rainy days.

  1. How much electric power do you predict your system will produce at noon on the summer solstice ?

  2. Non-clickable links! Fix it 😛

  3. I would expect an efficiency to be a unitless quantity however the plot states it as being kWh/kW so it has dimension hours. How should I interpret this figure?

  4. An interesting observation would be to check what is the average production during winter and compare it with the average value during summer. I believe you will be surprised to see that during summer, high temperatures will bring down the efficiency of solar panels, although light levels will be higher.

  5. Why have they used a lower case k for their units? Should be K for Kilo.

  6. Do you have any numbers worked out yet as to how long until it pays it self off?

  7. Buenas tardes 🙂 ha redactado genial este articulo. no soy de comentarios pero hoy si lo hago! Me encantó tu blogVer otra web interesante de web automaticas Si quires aprender hacer webs automaticas no lo dudes Un gran cursos el de NOSESEO.cOM
