There are mainly monocrystalline, polycrystalline and thin film panels. Monocrystalline silicon is highly efficient but expensive, polycrystalline silicon is cost-effective, and thin-film panels are suitable for large-area applications.

It needs to be calculated based on your electricity demand and the power of each panel. This can usually be estimated by dividing the total demand (kWh) by the power generating capacity of individual panels (kW).

Installation time usually ranges from a few hours to a few days, depending on the complexity of the system and the efficiency of the installation team.

Most solar panels have a lifespan of 25 to 30 years, but performance may gradually decline over time.

Maintenance is relatively simple and usually only involves regular cleaning and checking connections.

Yes, many systems are designed to be grid-connected, allowing you to draw power from the grid when needed.

Yes, but the efficiency will be reduced, usually still producing about 10-25% of normal power on a cloudy day.

Common problems include shadow shading, dirt buildup, deterioration, and connection issues.

The main difference lies in the voltage and capacity, and the voltage demand and power output of the system should be considered when choosing.

Connect the positive terminal of the battery to the negative terminal of the next battery to ensure that batteries of the same type and capacity are connected in series.

Typically 5 to 15 years, depending on usage conditions and charge/discharge cycles.

Lithium batteries are lighter, more efficient, and last longer, but cost more; lead-acid batteries are cheaper but heavier and have a shorter lifespan.

Consider capacity, discharge rate, charging time, usage environment and budget.

Observe the battery's charging time, discharging time and whether there is any expansion or leakage.

Common causes include too many charge/discharge cycles, extreme temperatures, overcharging or overdischarging.

Most lithium batteries will lose performance in extreme temperatures and it is recommended that they be used within the manufacturer's recommended temperature range.

It is not recommended. Fully discharging the battery may damage the battery and result in a loss of capacity.

Converts direct current to alternating current for use in homes and equipment.

The main types are sine wave inverters, modified sine wave inverters and multi-function inverters.

Selection is based on the type of load (e.g. household appliances), power requirements and system configuration.

The typical service life is 5 to 10 years, depending on the conditions of use and maintenance.

Output power ranges from a few hundred watts to several kilowatts, and the choice should be made taking into account the total load requirement. topbull inverters are mainly available in the power range of 2,000 to 5,000 watts.

Usually between 85% and 95%, the higher the efficiency, the less energy is lost.

Some inverters make noise when they are operating, especially the fan type.

Yes, the inverter is one of the key components of a solar power system.Go Buy Solar Inverter

Yes, but you need to make sure that their configurations and control systems are compatible.

Regular inspection and cleaning is required to ensure proper operation.

Most inverters have overload, short circuit and thermal protection.

The main functions include charge management, discharge control, load management and system monitoring.

Selection is based on system voltage, load demand and controller type (PWM or MPPT).

PWM controllers are simple but less efficient and suitable for small systems; MPPT controllers are efficient and suitable for large-scale applications.

MPPT controllers typically have efficiencies above 95%, while PWM controllers are lower.

View the system's voltage, power and current through the controller's display or by connecting to the monitoring software.

Suitable for domestic, commercial, agricultural and remote power supply.

Prevents overcharging and overdischarging by limiting the charging voltage and current.

Yes, proper charge/discharge management can help extend battery life.
