When choosing solar LED street lights suitable for home yards, you need to consider the balance between lighting needs, sunlight conditions, battery capacity and lamp power. The following are specific suggestions:
1. Recommended power range
5W~20W solar LED street lights can meet the needs of most home yards:
5W~10W: suitable for small yards (10~30㎡), providing basic lighting (such as paths, doorways).
15W~20W: suitable for larger yards (30~50㎡) or requiring brighter lighting (such as courtyard activity areas, parking spaces).
＞20W: usually used in large gardens or commercial places, and families generally do not need too high power.
2. Key selection factors
(1) Lighting needs
Functional requirements:
Safety lighting (anti-fall, anti-theft): 5W~10W, warm white light (3000K~4000K).
Decorative/atmosphere lighting: 3W~5W, low color temperature yellow light (2700K).
Activity lighting (dining, entertainment): 15W~20W, high brightness white light (5000K~6000K).
Coverage area:
About 1W power is required for every 10㎡ (for example, a 30㎡ yard can choose 3W×3 lamps or 1 10W centralized lighting).
(2) Sunlight conditions
Sunny areas (average 4~6 hours of sunshine per day):
5W~10W street lights with **10W~20W solar panels** + 12V 20Ah batteries (can support lighting all night).
Rainy areas:
It is necessary to increase the battery capacity (such as 12V 30Ah) or reduce the lamp power (such as 5W) to ensure battery life on cloudy days.
3.Battery and battery life
Typical configuration example:
10W LED light + 12V 20Ah lithium battery (240Wh):
8 hours of light per night (power adjustable):
Full power 10W: battery life of about 24 hours (actually light in different time periods as needed).
Half power 5W (intelligent sensing mode): battery life extended to 2~3 days.
4.Solar panel matching
Solar panel power ≈ lamp power × 2~3 times (to compensate for charging loss):
5W lamp → 10W~15W solar panel
10W lamp → 20W~30W solar panel
3. Installation suggestions
Height and spacing:
The height of the light pole is 1.5~3 meters, and the spacing is 5~8 meters (to avoid shadows).
Intelligent control:
Select the human body sensor + light control mode, turn off during the day, low power at night, and fully light when people approach, saving power.
4. Cost-effective solution
Economic model for small courtyard:
5W LED + 10W solar panel + 12V 10Ah battery → about ￥100~200
Balanced model for medium courtyard:
10W LED + 20W solar panel + 12V 20Ah battery → about ￥200~400
Most family courtyards can choose 5W~15W solar LED lights, focusing on matching battery capacity (recommended ≥20Ah) and solar panel power (2~3 times the lamp).
