Why Use Solar Power

This is a question that is being raised more and more by homeowners, as they are facing increasing costs for electricity usage and the power grid is becoming less reliable. A well-designed solar system home system can lower your monthly electricity bills, provide energy independence, offer backup power protection, and save you money over time. JOZOKING (TIANJIN) TECHNOLOGY CO., LTD. makes a top-rated battery energy storage system solution to be perfectly compatible with solar panels. The solar home energy storage system further enhances the potential of the grid power storage system and solar power storage. Here, we will explain how solar energy works, the advantages of solar and the selection of solar equipment for your home.

How Solar Power Works for a Home

A home solar system consists of three main components: solar panels, a solar inverter, and a battery energy storage system. By having a grasp of the basic flow, you'll be better able to understand why the storage of energy in a home is important.

1.1 Solar Panels Capture Sunlight

Sunlight is turned into direct current (DC) power by solar panels (photovoltaic or PV modules). The wattage of the panel and the number of hours of sunlight that your location receives determine how much power a panel will generate. For example, a standard 400W solar panel receiving about 5 peak sun hours will produce around 2,000 watt-hours (2 kWh) daily. But, if no battery energy storage system is available, then any power that is not used right away will be exported to the grid or lost.

1.2 The Inverter Converts DC to AC

Alternating current (AC) is used by most home appliances. This inverter will take the direct current (DC) electricity generated by your solar panels or by your home electricity storage battery and turn it into alternating current (AC) electricity that you can use in your lights, refrigerator, TV and other devices.

1.3 Battery Energy Storage System Stores Excess Power

This is where grid power storage can come in handy. Your solar panel(s) can generate more energy than your house requires during the day. A battery energy storage system stores the excess for later use instead of sending it to the grid for minimal compensation. At night or during a blackout, your solar power storage system dispense stored electricity to power your home. This makes an average solar system home into an energy hub that may operate on its own.

The Benefits of Home Solar + Storage

2.1 Lower or Eliminate Electricity Bills

After installing a home solar system with energy storage, every kWh you generate and store is electricity you do not have to buy from the utility. Typically, savings would be 3X to 5X the initial investment over the 20 years.

2.2 Backup Power During Grid Outages

A typical grid-tied solar system will go offline during a power outage for safety purposes. But with the addition of a battery energy storage system, your home disconnects automatically from the grid (islanding) and will continue to power with solar energy stored within the battery. This is true grid power storage—protecting your family from load shedding, storms and grid failures.

2.3 Energy Independence

Having the appropriately sized solar power storage systems makes it so that you can cut down or even eliminate the need to rely on the utility company. No more rate hiks, time of use pricing, or an unstable grid. Your solar system home is your solar power generation unit!

2.4 Environmental Impact

Solar is a clean energy source, and is renewable. Combine with a home energy storage battery, wasted energy is reduced, and clean electricity is used to its fullest potential. Each kWh stored and consumed afterwards is a kWh that is not produced from fossil fuels.

How to Choose the Right Solar + Storage Equipment

There are many factors to consider when choosing components for a home solar system. The most important decisions are on the battery capacity and solar panel size.

3.1 Determine Your Daily Energy Consumption

A good place to begin is by examining your electric bill. Calculate the average usage of kWh per day in your electricity bill. A small home could be 10–15 kWh per day while a larger home with air conditioning and electric appliances could be 25–40 kWh per day. Your home energy storage battery should be able to meet the energy needs of the evening and overnight, which are usually 60-80% of your total daily energy needs. Many typical homes can be powered by a 10kWh battery energy storage system.

3.2 Match Battery Capacity to Your Needs

JOZOKING provides rack mounted and wall mounted grid power storage batteries ranging from 2.4kWh to more than 20kWh for a single battery. If you are looking for a home solar system, consider the following:

Basic backup (essential loads only): 5 to 10kWh battery

Whole-home overnight backup: 10 to 20kWh battery.

Full energy independence (multiple days): 20kWh+ battery

Our LiFePO4 battery energy storage systems offer 4000 to 6000 cycles, providing 10–15 years of daily use.

3.3 Calculate How Many Solar Panels You Need

The amount of energy that each solar panel can generate depends on your location and is predictable. Use this formula:

Daily panel output (kWh) = Panel wattage × Peak sun hours ÷ 1000

Example: A 450W panel × 5 peak sun hours = 2.25kWh per day.

The number of panels (or solar array) needed to recharge a 10kWh home energy storage battery for daytime loads is 6-10 panels (2.5-4.5kW array). To be safe, slightly oversize your solar array to account for cloudy days and winter months. The efficiency of a solar energy storage system depends on the total amount of energy that the solar panels generate, as they need to supply energy to the home during the day and to fully charge the battery energy storage system before night.

3.4 Choose a Hybrid Inverter

A hybrid Inverter controls both solar panels, the grid and your grid power storage battery. It features time-of-use shifting, exports surplus power when it makes sense and offers hassle-free blackout backup. Many lithium battery energy storage system solutions by JOZOKING are designed to be installed together in the same enclosure with hybrid inverter, thus simplifying installation and saving space.
