Solar Performance LUX Measurement
Solar performance discussions on these boards often have phrases like “overcast day”, etc. I’m wondering if one of the inexpensive phone apps would lead to a better understanding of panel performance....

If, and this is a biggie, you can access quantatative information at Sandia National Labs, qualifying measurements of solar to voltaic panel cell response an accuate idea will emerge re: LUX and cell productivity. You can also try and work up a Trends & Tendencies series of formulasbut LUX to panel output relationships can be misleading. Personally I would try to study a bit if information is available on the web. Optical illumination and panel cell photo response are two different animals. As an extreme example 1, 000 watts of LED illumination can be applied and it would not equal the energy of what is produced in the middle of a fog bank. Conclusion: Double and triple check assumptions.
