i have built a solar cell phone charger circuit using many solar cells They provide 36V/1.5A at maximum,
but when i connect the regulator IC 7806, the current and voltage of the cells drop to 8V/300mA, when i connect the mobile to charge they further drop to 4.7V/200mA,which slows the charging process.........whats the problem,why does the power drop soo much?
