Solar and wind power can be complementary during time's difference. Ingeneral, when sunligh is weak the wind speed is relatively higher, moreover, the wind is milder while the sunlight is stron.
The latest technology of LED is adopted for whole series and the lamp is durable up to 50,000 hours life time. In additional, the advanced PWM technology is introduced for recharging control for obtaining the maximum electricity yeilding. Simple and reigid design of scheme made sure for resistant of wind-pressure; systemoptimized design of circuit provide the function that the battery and the other components can long life span.
