AFAIK you can increase the efficiency by changing the angle that the solar panels make with the ground/ horizontal (Inclination angle). Let’s assume this angle as Beta.Andres125sx wrote: ↑Sat Jan 25, 2020 12:22 pmI´m going to go even further and build a passivehaus. Triple glased windows, hermetic house, around 15cm isulation and a ventilator wich takes the heat of the air pumped out to warm fresh air being pumped in (can´t find the name in english)
I really think passivehaus standard or similar should be mandatory nowadays, it´s utterly absurd to build anything wich requires heating (both for economical and environmental reasons) when we can do it good enough to not need any significant heating or cooling, and quite easily btw, it´s just a 10% increase in the bill wich is paid off in less than a tenth of the lifespan

The best option to produce the most Usable power across the day is to install a system with 2 arrays, one east facing and one west facing or at close to this as possible.
This will give you your own power from Sun up to sun down.
My system is a compromise like most, due to my house design and orientation, I have 1.5kW facing NE and 3.9kW facing NW.
My idea (just guessing, nothing serious) was some sort of extremelly simple system wich allows panels to be moved up and down from the back, so the front edge is always in contact with the ground, but the back one can be at height 1 or height 2 to accomodate to sun azimut in winter and summer. Tracking sun along the day is much much more complicated, as you need the complete frames to turn, but if it´s just a simple azimut adjustment, it can be done quite easily I think. But no idea what improvements would be expected
I´m construction engineer btw
For winters: Beta = phi + 15 degrees
For summers: Beta = phi — 15 degrees
Phi is the Latitude angle, which varies with the Latitude. For example, if you live at 30 degree North/ South, your latitude angle is 30 degrees.
Based on this, you can make simple adjustments on the equinoxes every year. Bear in mind that these are very simplified/ rudimentary numbers. But, I think it can help and do let me know of the results, if you’re gonna implement this
