In acest tutorial video, va vom arata cum puteti sa va optimizati sistemul fotovoltaic pentru a obtine o productie maxima chiar si pe timp de ceata sau innorat. Veti vedea cum am reglat parametrii sistemului, cum am setat boilerul pentru a reduce consumul si cum am obtinut o productie maxima chiar si in conditii nefavorabile. Acest tutorial este perfect pentru cei care doresc sa isi maximizeze productia de energie solara si sa reduca costurile asociate.
Un montaj cu Arduino care utilizează un senzor LDR (Light Dependent Resistor) poate fi utilizat pentru a detecta nivelul de lumina ambientala si a lua decizii in consecinta. In acest montaj, Arduino este conectat la senzorul LDR prin intermediul unui circuit de rezistori. Arduino citeste semnalul primit de la LDR si il foloseste pentru a determina nivelul de lumina. In functie de nivelul de lumina detectat, Arduino poate declansa diferite actiuni, cum ar fi aprinderea sau stingerea unei leduri sau controlul unui motor.
Adaptat la un dimmer de 4kw ca in video.
