Why do my solar lights only work for an hour?

Sometimes, the light stops working simply because plants in the area have grown so much they block much of the daylight the solar panel needs to charge the device. … Once the panel receives light for a couple hours, the solar light should illuminate if you put your hand over the panel.

Do solar lights charge on cloudy days?

Although the direct sunlight will be blocked on cloudy days, the solar-based lights are still receiving a charge. The clouds are diffusing the strength of the sunlight but solar irradiance is still transmitted from the sun to the earth. So, the solar power system still charges during cloud cover.

Can you use regular AA batteries in solar lights?

Solar lights need somewhere to store the energy they absorb from the sun, which is why they require rechargeable batteries. Regular batteries cannot store energy the way NiMH and NiCd batteries do, resulting in damage to your solar lights. … Alkaline batteries also only power your solar lights for a short period of time.
