From here we learn that it only takes 5 steps to achieve energy independence. You no longer need to rely on the utility grid or noisy and high-maintenance generators.
Solar energy storage is a crucial part of these five steps. You will learn more about solar energy storage systems from this blog.
What is a solar energy storage system?
Solar energy storage systems combine photovoltaic power generation and energy storage technology. This solves the stability problem of photovoltaic power generation.
The system usually consists of photovoltaic modules, energy storage battery modules, power electronic converters (inverters), and control units (controllers).
By storing the electric energy generated by the solar module in the energy storage battery module, the system can ensure a stable supply of electricity. This will avoid power fluctuations caused by sunlight intensity changes.
In addition, solar panel generation and energy storage systems can also reduce operating costs and adapt to different application scenarios.
For example, domestic, commercial, and industrial areas.
As technology and production mature, it is expected that solar energy storage systems will be more widely used around the world in the future.
They will become a significant force in promoting renewable energy.
What benefits can PVMARS's solar energy storage system offer you?
Solar panels and energy storage systems have become a beacon of hope.
It’s a revolution that delivers clean, renewable electricity directly to their doorsteps by letting consumers install their own photovoltaic (PV) panels and energy storage solutions.
The concept is simple, but the impact is huge, as we usher in a future where generating and using electricity is cleaner, greener, and more convenient than ever before.
Solar panels: Capture sun energy
Solar panels are no longer the preserve of large installations but are increasingly part of our homes, schools, and businesses.
Its beauty lies in its versatility and scalability.
Whether you’re considering a solar panel array on your roof or ground-mounted solar panels in your backyard, they can meet your energy needs.
PVMARS provides solar panels with TOPCon, HJT, and BC technologies.
There are also BIPV solar panels that can be seamlessly integrated into the house’s architecture.
Alternatively, flexible solar panels can be installed discreetly to blend in with the landscape.
They are both a source of energy and evidence of our commitment to a more efficient, greener, cleaner, and more sustainable future.
Energy storage systems: The power of resilience
Solar panels generate electricity during the day when the sun shines, while energy storage systems provide a stable electricity supply.
They can store excess energy generated by photovoltaic panels during the day. This ensures that power can be supplied even when the sun sets or on cloudy days.
These systems act like your personal energy bank, allowing you to draw on power when you need it.
Energy storage methods can be divided into three types: physical, chemical, and electromagnetic.
Physical energy storage: Pumped hydro, compressed air, and flywheels.
This can be understood as the water tower on the top of a high-rise building, and the reservoir on the top of the mountain in some areas. Because they require a huge investment in resources, they are mainly used by utility grid companies and government facilities.
Chemical energy storage: Lead-acid gel batteries, lithium-ion batteries, sodium-sulfur batteries, flow batteries, etc.
Electromagnetic energy storage: primarily includes supercapacitor energy storage and superconductor energy storage.
Consumers tend to prefer chemical energy and electromagnetic energy. Currently, chemical energy storage is dominant, but electromagnetic energy storage is the future subject.
Chemical energy storage systems:
Evolving from traditional lead-acid gel batteries to advanced lithium-ion technology.
PVMARS uses lithium iron phosphate batteries due to their small size and large capacity.
It is the safest and most environmentally friendly of all types lithium-ion of battery.
In addition, our battery cell raw material suppliers include CATL, BYD, Ganfeng, and other well-known brands.
Provide at least 5 years of free warranty service (10 years may be provided depending on cooperation depth).
They are compact, efficient, and can be integrated seamlessly with solar panels. Modern energy storage systems offer convenience, energy independence, and resilience.
Inverter: The bridge connecting energy storage systems and electrical equipment
The main function of an inverter is to convert the DC power from the battery into AC power. Solar energy storage systems generally use controllers.
Nowadays, most small and medium-sized solar energy storage systems are hybrid all-in-one controller + inverter machines. The photovoltaic controller and inverter are integrated to facilitate installation.
There are currently three options for inverters: modified wave inverter, high-frequency sine wave inverter, and power frequency sine wave inverter, which are suitable for different occasions.
Energy storage inverters:
Connect the battery to the utility grid (or the load).
The principle is the same as that of a hybrid all-in-one inverter, which inverts DC power from the battery into AC power.
However, the energy storage inverter is more powerful, and energy can flow in both directions.
This is, it can invert DC power into AC power and send it to the power grid or for use by AC loads.
It can also rectify alternating current into direct current and let the public utility grid charge the battery, so the energy storage inverter is also called a bidirectional converter PCS.
Symbiosis: Solar energy storage system
When you combine solar panels with an energy storage system, the magic happens. This dynamic duo will provide homeowners with an energy-independent solution.
Use clean energy production and consumption. During the day, solar panels power your home while charging your energy storage system.
Excess energy is stored for use when the sunlight is insufficient. This is a reliable method of generating electricity that minimizes your reliance on the grid and lowers your energy bill.
It can even come true completely off-grid, with zero electricity bills, zero noise, and a top-notch green and healthy lifestyle that guarantees electricity consumption anytime and anywhere.

How to choose solar batteries size?
The battery of the solar energy storage system is the main force in storing electricity and is the key to allowing you to use electricity anytime and anywhere.
Therefore, before purchasing a battery, we need to consider the following elements:
Your load equipment and usage time determine the battery size and cost.
Assume your monthly electricity bill is 500USD
Monthly electricity consumption: 550 / 0.5 = 1100kwh
Daily electricity consumption: 1100kwh / 31 days=35.48kwh
Power: 35.48kwh / 24hours=1.48KW
Note: The above are average values. In actual use, during the summer, the power consumption of air conditioners and other electrical appliances will be much higher than this power.
When household appliances sleep, turn off, or stand by at night, the power will be much lower than this.
Can be used to estimate the energy storage system design capacity.
If you need to maintain a power supply for 10 hours, you will need a battery size of approximately 1.48KW x 10 hours = 14.8kwh.
Depending on the battery size determines the battery cost you will pay.
In addition, industrial and commercial projects to get the actual battery size and cost more accurately.
