太阳能灯具参数

1. Solar Panel / PV Module Parameters.

The "water intake" determines the system's energy source.

Parameter Name	Expert Interpretation / Recommended Standard
Solar Cell Type	Monocrystalline silicon has the highest efficiency (>21%), good performance in low light conditions, and is suitable for the European region.
Peak Power, Wp	Based on the geographical location (peak sunshine hours) and the power consumption of the entire lamp, it is recommended to leave a margin of 1.5-2 times.
Conversion Efficiency	Recommendation >20%. The new EU regulations focus on conversion efficiency per unit area.
Encapsulation	It must be tempered glass laminate. Avoid PET/epoxy resin processes (it is prone to yellowing and sandblasting after 1-2 years outdoors).

2、Battery Storage

The "reservoir" of the system is the part of outdoor solar lights most prone to failure.

Parameter Name	Expert Interpretation / Recommended Standard
Battery Chemistry	Lithium iron phosphate (LiFePO4) is the mainstream choice.
Capacity, Ah/Wh	It is recommended to use Wh (watt-hour) (voltage × Ah) to more accurately measure the size of energy storage.
Cycle Life	It is recommended to perform ≥2000 cycles at 80% DOD (depth of discharge).
Working Temp	Key parameters! Slovakia has harsh winters; therefore, the battery's charge/discharge capabilities between -20°C and +60°C must be confirmed.
BMS	Overcharge, over-discharge, short-circuit, and low-temperature charging protection are mandatory.

3.Control system parameters (Solar Controller / Driver)

The system's "brain" is responsible for energy scheduling.

Parameter Name	Expert Interpretation / Recommended Standard
Charging Mode	MPPT (Maximum Power Point Tracking) is 15-30% more efficient than PWM and is suitable for cloudy/rainy/Nordic weather.
Light Threshold	Critical illuminance for automatic on/off sensing (unit: Lux).
Control Strategy	Time-slot dimming: for example, 100% for the first 3 hours, 50% for the middle 3 hours, and 30% in the early morning (for energy saving and battery life).
Static Current	It is recommended to keep the current <1mA to prevent prolonged rainy weather from draining the battery and causing damage.

4. Optical and LED Parameters

The system's water output determines the lighting effect.

Parameter Name	Expert Interpretation / Recommended Standard
System light Efficacy	Including controller losses, a power consumption of ≥160 lm/W is recommended. The lower the power consumption, the longer the battery life.
CCT	European customers prefer warm colors in the 3000K-4000K range to create a natural landscape atmosphere.
CRI	The botanical garden scene requires Ra > 80.

5. System Performance and Reliability

Parameter Name	Expert Interpretation / Recommended Standard
Autonomy Days	Key! The number of consecutive rainy days during which the lights can continue to work normally without sunlight (recommended ≥3-5 days).
Charging Time	The time required to fully charge the battery under standard sunlight intensity (generally recommended to be 6-8 hours).
IP Rating	Outdoor lighting fixtures must meet IP65/IP66 standards.
Housing Material	UV-resistant PC or die-cast aluminum + anti-corrosion baking paint process.

Structural Parameters	Detailed Information	Industry Expert Advice
Solar Type	Integrated/Split	All-in-one solar lights or split-type solar lights.
Fixture Size	Main Body	Partial dimensions including the battery compartment and LED module.
PV Panel Size	*L W * H**	It affects the light-receiving area and installation wind resistance (this needs to be considered due to the strong winds in Slovakia).
Bracket Spec	Spigot Size	It is compatible with the diameter of utility poles (e.g., Φ60mm, Φ76mm).
Mounting Height	Recommended Height	Recommended height for achieving optimal illumination coverage (e.g., 3-6m).
Net Weight	Load-bearing Assessment	Total weight including battery, used to evaluate installation.

灯具参数

Lighting fixtures focus on the electrical safety, optical distribution, structural reliability, and intelligent control of the entire unit.

Dimensions	Parameter Name	Key Description
Electrical Specifications	Input Voltage, V)	AC 220-240V (EU standard) or DC 12V/24V/48V.
	Power Factor, PF	It is recommended that PF > 0.9 (energy conservation and emission reduction requirements).
	THD	It is recommended that THD be less than 15% to avoid interference with digital infrastructure.
	Surge protection
	Protection Class	Class I (with ground wire) or Class II (double insulation).
Optical Indicators	Beam Angle	Such as 15°/30°/60° or asymmetric light distribution (for wall washing/road washing).
	UGR	For landscape/indoor educational spaces, a UGR < 19 is recommended.
	LOR	The effective proportion of the light source output after passing through the lens/lampshade.
Structural Protection	IP Rating	The outdoor areas of the botanical garden must meet IP65/IP66/IP67 standards.
	Impact Rating	Impact resistance rating: IK08 - IK10 is recommended for outdoor public places.
	Housing Material	Such as 6063 die-cast aluminum and anodizing process.
