> Quick answer: The panel’s power output ranges from 1.5 watts to 200 watts [3][9][12], while typical battery capacities are around 1000 mAh, though they can range up to 2000 mAh [6][19]. Real-world performance is often below rated power due to weather and shading.
Solar lamps offer a versatile solution for lighting needs in Romania, but understanding their energy balance and capacity is crucial. From the panel’s power output to battery capacity, we’ll explore how these solar-powered devices perform throughout the year.
Panel Power Output
The power output of solar panels used in lamps varies widely depending on the model and intended use. Some smaller lamps may feature a 1.5-watt panel [11], while larger systems can include a 200-watt panel capable of producing around 1 kilowatt-hour (kWh) per day under ideal conditions with 5 peak sun hours [3]. In real-world tests, a 200-watt panel produced an actual output of 160 watts at peak irradiance [12], which is approximately 80% of its rated power. This shows that even under favorable conditions, the actual output can be lower than expected.
Battery Capacity
Battery capacity for solar lamps typically ranges from 500 mAh to 2000 mAh, with common values being 1000 mAh and higher [6][19]. Lithium-ion polymer batteries are often used, offering nominal voltages of around 3.7V [6][24], providing reliable energy storage for the LED components.
Energy Balance: Summer vs Winter
Summer Daylight Output
During summer days with longer daylight and high solar insolation, a 200-watt panel can generate between 1–1.3 kWh per day [3][12]. This aligns with peak sun hour estimates of around 5-6.5 hours daily in sunny regions.
Winter Daylight Output
In winter, the energy generation drops significantly. While not directly measured by the sources, rough estimates suggest a fixed PV panel could produce up to 5 Wh per day per watt [13]. For portable systems, a more conservative estimate of 3 Wh/day per watt is recommended due to suboptimal positioning and shading [13], leading to an estimated winter output of around 600 Wh for a 200-watt panel.
System Efficiency
The energy balance of solar lamps is heavily influenced by system efficiency. Battery round-trip efficiency is about 80%, meaning only 80% of stored energy is usable [13]. This highlights the importance of oversizing the solar panel to compensate for inefficiencies and shading effects, where complete shading can eliminate output entirely [17].
Shading Impact
Modern panel technologies like TOPCon or bifacial designs are designed to maintain significant power output even under partial shading. For example, a half-shaded panel may still produce nearly half its rated power [17], providing resilience in real-world conditions.
Key Takeaways
- Panel power outputs range from 1.5 watts to 200 watts.
- Typical battery capacities are around 1000 mAh but can vary up to 2000 mAh.
- Real-world output is often below rated power due to shading and weather conditions.

varies across the USA, and solar engineers like to measure it using peak sun hours. Using the map below, you can see the approximate peak sun hours for your location. If you multiply the peak sun hours by 200 watts, you can estimate how much energy a solar panel will make on an average day. For example, if you live in South Carolina, take the 5 peak sun hours multiplied by 200 watts to get 1,000 watt-hours per day. That’s the same as one kilowatt-hour (kWh). On the other hand, in the desert of New Mexico, expect to get closer to 1,500 watt-hours per day (1.5 kilowatt-hours). What can you run with a 200-watt panel? A 200 W solar panel paired with a portable solar generator can help you power devices, charge smartphones, and run even small kitchen appliances. Because the panel can generate around 1 kWh of electricity per day, it is the perfect companion to a solar generator with around 1 kWh of energy storage, like the Bluetti AC180. Here’s how long you can expect a 200 W solar panel and battery to run different appliances: *Assumes 1,000 Wh battery. All of the 200-watt solar panels listed above can work to charge a portable solar generator, but there are a couple of important things to know first: the open circuit voltage (VOC) of the solar panel and the input port of the solar generator.

A final note on wattage: The wattage listed by the manufacturer is the maximum under ideal conditions—but don’t expect those conditions. Factors, including cloud cover and the angle of the sun can substantially impact power output. It’s not uncommon to get only half of the wattage listed by the manufacturer, so it may be useful to buy a more powerful device to compensate.

in sunny areas each Wp of a fixed PV panel can produce up to 5 Watt hours (Wh) per day (1825 Wh/yr. per Wp). For a portable PicoPV system the panel is not always in the best position, and sometimes can be shaded for some time, so that even in sunny areas it is safer to assume a lower output ratio of about 3 Wh/day per Wp.[8] Battery There are different types of batteries used in the systems, lead-acid (33%) and NiMH (60%) batteries being the most common types, while Li-Ion (7%) batteries are presently used only in few cases.[2]These replace lower quality batteries, such as the lead-acid battery. A charge controller is important to protect the battery from damage through overcharging or deep-discharging.[9]With a round-trip battery efficiency of about 80% for most batteries this implies that, if all energy is consumed in the evening or night, the practical available energy for the consumer of a PicoPV system is about 2.5 Wh/day per Wp of the PV panel.[8] Lamp More than 50 PV lamp models are available on the market, which can be equipped with compact fluorescent lamps (CFL) or light emitting diode (LED). In most models available so far, a small solar module is separate from the lantern, so that it can be placed outdoors without the lantern being exposed to the weather.
