Solar Panels 

A solar panel system is a power generation system with photovoltaic modules.

The solar electricity panels system is a power generation system of photovoltaic modules.

It mainly includes solar panels, batteries, controllers and inverters, and other auxiliary equipment including PV mounts, solar cables, etc.

In addition, depending on the capacity of the system, a sink box, AC/DC distribution cabinet, and other equipment may be required.

Solar panels (also called solar modules) are the core part of a solar power system and the most basic part of a solar power system.

Solar cells, also known as "solar chips" or "photovoltaic cells", are thin sheets of optoelectronic semiconductors that directly generate electricity. Individual solar cells cannot be used directly as a power source.

ZMS solar PV system products can be widely used in homes, ranches, base station projects, and other power uses.

Types of Solar Panels

Monocrystalline Solar Panels

Monocrystalline sun cable panels are modules consisting of high conversion efficiency monocrystalline silicon cells in different series and parallel arrays.

ZMS monocrystalline solar panels are robust and have a life span of up to 20 years.

These solar panels offer higher conversion efficiencies than polycrystalline solar panels and are less expensive to produce.

Amorphous Silicon Solar Panels

Amorphous silicon solar PV panel is a new type of thin-film solar panel that appeared in 1976. 

It is completely different from monocrystalline silicon and polycrystalline silicon solar panels, the process is greatly simplified, silicon material consumption is very little, and electricity consumption is much lower.

Its main advantage is that it can generate electricity even in low-light conditions. However, the main problem of amorphous silicon solar panels is the low photoelectric conversion efficiency, with an internationally advanced level of about 10%. 

It is not stable enough, with the extension of time, its conversion efficiency decays.

PV System + Energy Saving and Emission Reduction in Wastewater Treatment Plants

Sewage treatment plants are energy-intensive, high-energy industries, and many of the world's sewage treatment plants are still in the stage of energy consumption of electricity.

Treatment of each ton of sewage power consumption in the 0.2-0.3 degrees or so, the cost of electricity accounts for about 50% -70% of the cost of sewage treatment, if the enterprise through technical means reduces 30% of the power consumption, then you can reduce 18% of the cost of sewage treatment.

Advantages of Utilizing Photovoltaic Electricity

As the sewage treatment plant covers a large area, surrounded by open space, abundant light, and high power consumption, the construction of a distributed photovoltaic power station project has a unique advantage.

It can realize the effective use of space resources by adding photovoltaic modules on top of the roof, vacant land, parking space of the plant, and the work unit space of the sewage treatment plant such as rapid sedimentation tank, two sedimentation tanks, aerobic tanks, and biochemical tanks.

Photovoltaic + Wastewater Treatment Plant Application Value

  • Social Benefits

    Enhancement of national energy security.

    Enhance the utilization rate of land resources.

  • Economic Benefits

    Power Generation Efficiency

    The plant area has open space, few obstructions, and maximizes the effective light hours, which maximizes the power generation efficiency of the PV modules.

    Economic cost perspective

    At present, the electricity consumption of the wastewater treatment plant is two kinds of electricity: flat section electricity consumption and peak-valley time-sharing electricity consumption. The cost of flat section electricity consumption is about 0.55 yuan/kWh, and the average daytime electricity consumption during peak-valley time-sharing is about 0.7 yuan/kWh.

    Self-invested income

    PV power generation is self-generation and self-consumption, prioritizing the use of electricity generated by PV, the reduction of daily electricity expenditure is equivalent to income.

    Electricity Discount Mode

    The difference between the discounted PV electricity tariff and the utility electricity is equivalent to revenue.

    3 In case of abnormal utility power/blackout, PV power generation charges the battery to ensure the stability of the DC power supply of the communication system.

ZMS believes that the process method of prioritizing power supply by photovoltaic, supplementing power supply by storage battery, and backing up power supply by oil generator can also greatly solve the problem of communication network coverage in remote areas, areas without electricity, areas with difficulty in drawing power from the utility, and areas with unstable utility power, and ensure the normal operation of base stations.

ZMS also encourages the innovation of PV communication intelligent new energy series, using PV power generation priority power supply, energy storage as a supportive power supply, the utility power into supplementary power supply, generator as a backup emergency power supply mode.

Photovoltaics and Rural Electricity Saving Heating Programs

Advantages of using photovoltaic system solutions for rural houses:

  • Thermal insulation and heating

    The modules on the roof can reduce the indoor temperature, especially in summer, through the photovoltaic panels will be light energy into electricity, photovoltaic panels are equivalent to the heat insulation layer, measured can reduce the indoor temperature by 3-5 degrees.

    In winter, photovoltaic panels are equivalent to the building to wear a coat and, to a certain extent can play a role in insulation.

  • Saving Electricity

    In rural and urban income imbalance areas, if the rural house is installed with photovoltaic power generation, self-generated self-consumption of surplus power grid mode, you can save most of the electricity consumption, but also avoid the ladder tariffs.

    You can save most of the electricity consumption and avoid the steep tariff. You can have a large amount of money left over every year through photovoltaic power generation.

Solar Panel Parameters

Short circuit current(isc)


Solar cell positive and negative short circuit so that u = 0, at this time the current is the short-circuit current of the cell, with the change of light intensity and change.
Open circuit voltage(uoc)Volt(v)

Solar cell positive and negative terminals are not connected to the load so that i = 0, at this time the voltage between the positive and negative battery is the open circuit voltage.

The open-circuit voltage of a single solar cell does not change with the increase or decrease in the cell area, generally 0.5 to 0.7v.

Peak current(im)


It is the operating current of the solar cell when it outputs the maximum power.
Peak voltage(um)Volt(v)It is the operating voltage when the solar cell outputs the maximum power.

It does not change with the increase or decrease of the cell area, and is generally 0.45 to 0.5v, with a typical value of 0.48v.

Peak power(pm)


It is the maximum output power of a solar cell under normal operating or test conditions, which is the product of peak current and peak voltage: pm == == im × um.
It depends on the solar irradiance, the solar spectrum distribution, and the working temperature of the cell. The measurement standard is the European Commission's standard 101, and the conditions are irradiance lkw/㎡, spectrum aml.5, and test temperature 25℃.
Fill factor(ff)/It is also called the curve factor, which is the ratio of the maximum output power of a solar cell to the product of open circuit voltage and short circuit current. The calculation formula is ff=pm/(isc×uoc).
The higher the value of the fill factor, the more the output characteristics of the solar cell tend to be rectangular, and the higher the photoelectric conversion efficiency of the cell.
The coefficient is generally between 0.5 and 0.8, and can also be expressed as a percentage.
Conversion efficiency(η)/This refers to the ratio of the maximum output power of the solar cell when it is illuminated to the power of the sun's energy irradiated to the cell. That is η = pm (peak efficiency of the cell) / an (area of the cell) × pin (incident light power per unit area), where pin = lkw / ㎡ = 100mw / cm2.
