Hoje em dia, luzes solares are becoming more widely used whether in rural or urban areas. Luzes solares usam energia verde e renovável, eles absorvem a energia do sol e a convertem em eletricidade armazenada em baterias, em seguida, descarregue para a luz LED quando a luz solar funcionar.
No entanto, algumas pessoas ainda estão preocupadas com problemas que podem acontecer ao usar luz solar, um dos motivos é que acham que dá dor de cabeça trocar as pilhas depois 2-3 anos de uso.
Como fazer as baterias solares funcionarem por mais tempo? Aqui estão algumas dicas:
- Evite que as baterias sejam sobrecarregadas.
A vida útil da bateria de luz solar está intimamente relacionada ao acúmulo de calor gerado dentro da bateria, e a fonte de calor dentro da bateria vem principalmente da perda de energia da reação eletroquímica interna. Na reação de oxidação, a corrente de flutuação aumentará para gerar mais calor. Durante o carregamento de tensão constante, a corrente de flutuação aumentará com o aumento da temperatura, o que aumentará ainda mais a temperatura. Se as baterias estiverem sendo sobrecarregadas, a alta temperatura trará sérios danos às baterias, como perda de água da bateria, concha “protuberante”, Em casos graves, a bateria será descartada. Para evitar sobrecarga, it is necessary to provide the charging voltage value in strict accordance with the manufacturer’s instructions. Do not use a higher voltage charger on the batteries to avoid overcharging. It also requires the solar lights manufacturer to offer stable output voltage from the solar panel to the batteries when producing the solar lights. It is very important to buy from a professional & reliable solar light manufacturer or supplier.
2. Avoid the batteries insufficient charging.
Insufficient charging is mainly caused by the charging voltage setting is too low, or there is a problem with the control system. In addition, the position of the solar street light will also be affected. If the street light is placed under a tree or near a shelter, it will affect the illumination and cannot convert light energy into electrical energy, so that it cannot be charged or is insufficiently charged. Por isso, when installing solar lights, people need to pay more attention to the location, especially the solar panel location to make sure it can receive the sunlight as much as possible.
3. Avoid the batteries over-discharge.
The depth of discharge is closely related to the design charge and discharge cycles (service life) of the battery. Por exemplo, when the depth of discharge is 5%, the number of cycles is 10,000, and when the depth of discharge is 50%, the number of cycles is only 800. Serious over-discharge will cause the battery to be unable to activate to a better state, or even to be scrapped. With different discharge rates, the discharge time and termination voltage are different, and the effective capacity released is also different, and is affected by the ambient temperature.
