Is there a cost-saving solution for lithium battery purchase and transportation?2026-06-09T08:39:29+00:00

Due to the high transportation cost of lithium batteries, customers can purchase battery cases from us and buy battery cells locally.
The only requirement is that the input and output voltage of the locally purchased cells is consistent with the official parameters (24V nominal voltage).
The battery case is universal for all equipment, with connectors and power display panels included.

1. Regular charging takes about 6 hours, and a full charge takes 6-8 hours (the charger indicator turns green when fully charged);
2. The power display may be inaccurate for the first charge, and it will return to normal after draining the power and recharging once;
3. The indicator turns red when charging and green when fully charged; 4. The battery has natural loss if left unused for a long time;
5. The chargers of single-head/double-head brushes, roller brushes and robots are mutually universal.

What is the battery life of different cleaning equipment with a single set of lithium battery (2 batteries for robots)?2026-06-09T08:46:41+00:00

– Single-head brush: 1 lithium battery, battery life 8-10 hours (actual average current 4-5a, full load 5a)
– Double-head brush/roller brush: 1 lithium battery, battery life 4-5 hours (actual average current 6-7a, full load 10a)
– Cleaning robot: 2 lithium batteries, battery life 6-8 hours (equipped with 1 brush head motor + 2 walking motors inside the body)

What are the basic parameters of the universal lithium battery for cleaning equipment?2026-06-09T08:48:03+00:00

The lithium battery is universally applicable to single-head/double-head brushes, roller brushes and robots, with the following core parameters: nominal voltage 24V, nominal capacity 26AH, ternary lithium battery (6 series and 10 parallel), AC internal resistance ≤100mΩ, charging/discharging temperature -20~50℃, charging cut-off voltage ≤25.2V, discharge current ≤15A, discharge cut-off voltage ≥16.8V, weight 3.5kg, shell size 16924CM (24016090 mm for cell). The discharge capacity is 624Wh (24A*26V).

What are the core advantages and parameters of solar panel cleaning robots?2026-06-09T08:47:37+00:00

Cleaning robots have the highest cleaning efficiency (about 1450 ㎡/h, water consumption 0.4L/㎡) with anti-fall function, suitable for high-altitude cleaning. The 2024 new version can clean photovoltaic panels with an installation angle of up to 20°. Single-head robot (cleaning width 1.1m, applicable angle <20°) is for high-angle sloped roofs; double-head robot (cleaning width 1.4m, applicable angle <10°) is for large-area flat-laid power stations with gentle slopes and has better effect on stubborn stains. Robots are light and portable, with the same cleaning effect as double-head brushes for dust, water scale, bird droppings, slight oil pollution and rust.

How to choose between roller brushes and double-head brushes for medium and large power stations?2026-06-09T08:47:11+00:00

Roller brushes have a cleaning efficiency similar to double-head brushes (about 350 ㎡/h, water consumption 0.4L/㎡) and are suitable for power stations of 500-6000 square meters. Roller brushes are better for dry cleaning of non-heavy stains such as dust, water scale and slight dry bird droppings, while double-head brushes are recommended if there are a lot of stubborn stains.

What are the core features of double-head brushes and their applicable scope?2026-06-09T08:46:14+00:00

Double-head brushes add one brush head on the basis of single-head brushes, doubling the cleaning efficiency, with stable cleaning and one-hand operation available. They are suitable for power stations of 500-6000 square meters, with a cleaning efficiency of about 350 ㎡/h and water consumption of about 0.4L/㎡, and have better effect on stubborn stains than roller brushes.

What are the cleaning efficiency and applicable area of single-head electric brushes?2026-06-09T08:45:43+00:00

Single-head brushes have higher cleaning efficiency than manual brushes, with an electric rotating brush head that works well on stubborn stains such as bird droppings and thick dust. They are suitable for power stations of 100-500 square meters, with a cleaning efficiency of about 225 ㎡/h and water consumption of about 0.4L/㎡.

What is the applicable power station area and core advantages/disadvantages of manual cleaning brushes?2026-06-09T08:35:29+00:00

Manual brushes are light in weight and low in price, but less efficient than electric brushes, suitable for small-scale power stations with an area of within 100 square meters. Matching suggestion: 35CM brush head with 60W water pump, 55CM brush head with 120W water pump.

What are the applicable scenarios for dry and wet cleaning of different cleaning tools?2026-06-09T08:34:28+00:00

Brushed motors are only for wet cleaning; brushless motors are suitable for dry cleaning. Roller brushes perform better than double-head brushes in dry cleaning of dust, water scale and slight dry bird droppings, while double-head brushes are more effective for stubborn stains in wet cleaning. Robots support both dry and wet cleaning and are ideal for high-altitude solar panels that are inaccessible to manual operation.

Can all solar panel cleaning brush products be used for dry and wet cleaning?2026-06-09T08:33:38+00:00

Yes, all products support both dry and wet cleaning methods. Note that brushed motors require wet cleaning, while brushless motors are recommended for dry cleaning. For dry cleaning, roller brushes and cleaning robots are the first choices, with the cleaning effect ranking as: roller brush > double-head brush > single-head brush.
