Yunanengji Shahar yoritish uchun, traditional lighting equipment consumes a lot of energy and wastes a lot of energy, while solar street lights can reduce lighting electricity consumption and are an important way to save energy.
With its technical advantages, solar street lights use solar panels to convert into electrical energy for lighting, breaking the limitation of traditional street lights using city electricity, realizing self-sufficient lighting in cities and villages, and solving the problems of high electricity consumption and high electricity bills.
Ayni paytda, there are more and more solar street light manufacturers, and the market is mixed. How to choose and buy and distinguish good from bad? You can select from the following 4 aspects:
1) Quyosh panellari:
Commonly used panels are monocrystalline silicon and polycrystalline silicon. Umuman olganda, polikristalli kremniyning konversiya tezligi odatda 14%-19%, monokristalli kremniyning konversiya tezligiga erishish mumkin 17%-23%.
2) Batareya:
Yaxshi quyoshli ko'cha chiroqlari etarli yorug'lik vaqti va yorqinligini ta'minlashi kerak. Bunga erishish uchun, batareyalarga qo'yiladigan talablar tabiiy ravishda kam emas. Ayni paytda, quyoshli ko'cha chiroqlari odatda lityum batareyalardir.
3) Nazoratchi:
Ikkita turdagi kontrollerlar mavjud: PWM va MPPT. Mashinalar va odamlar kam bo'lgan davrlarda, energiyani tejash uchun umumiy yorqinlikni kamaytirish mumkin. Turli vaqt oralig'ida quvvatni oqilona o'rnatish orqali, yorug'lik vaqti va batareyaning ishlash muddati uzaytirilishi mumkin.
4) Yorug'lik manbai:
LED yorug'lik manbasining sifati quyosh ko'cha chiroqlarining foydalanish effektiga bevosita ta'sir qiladi. Oddiy LEDlar har doim issiqlik tarqalishi bilan bog'liq muammolarga duch kelgan, past yorug'lik samaradorligi, yorug'likning tez parchalanishi, va qisqa yorug'lik manbasining ishlash muddati.
