Best Solar Panel Battery Storage: Powering Your Home with Efficiency
With the rise of renewable energy, more and more households are transitioning towards solar panels. However, solar power systems may not provide electricity during times of peak demand or when the sun is not shining. This is where battery storage systems come in handy. In this article, we’ll be discussing the best solar panel battery storage systems available in the market that can help you save money and power your home efficiently.
A solar panel battery is a simple set of photovoltaic cells aligned together to convert energy from the sun into electricity. They are quite different from ordinary batteries that generate electricity from chemical energy.
The first cells were pieces of single-junction semiconductors that were made of silicon. They were very expensive since producing them required a lot of energy. Later, different forms of photovoltaic cells were produced using materials like Cadmium Telluride, Copper Indium Gallium Selenide, Micromorphous Silicon, and Amorphous Silicon. Research later found out that these materials could be deposited on thin pieces of ceramic or glass thus reducing the size of the system. Better materials and advanced production techniques did not improve the efficiency of the system; however, they reduced the cost of production making solar panels affordable to most people.
Today, the efficiency of photovoltaic cells is about 20%. However, with more research and technology, their efficiency at harnessing energy from the sun by capturing ultraviolet and infrared wavelengths can be improved.
What is a Solar Panel Battery Storage System?
A solar panel battery storage system is a technology that allows homeowners to store energy produced by their solar panels. The stored energy can be used later when there is no sunlight or during peak hours when electricity rates are high. Solar panel battery storage systems can help reduce reliance on the grid and save money in the long run.
Applications of the solar panel battery
Today, solar panels are a common sight in homes, public buildings as well as on the streets. They come in various sizes depending on the applications that are involved. Manufacturers are today introducing solar Shingles that are meant to suit the aesthetic needs of various architectural designs. These shingles may pass for ordinary roofing tiles; however, they are coated with layers of photovoltaic cells.
While all photovoltaic cells come with a dark, reflective surfaced panel, their applications vary widely. You can install your panel system in your backyard to power your pond aerator, garden sprinkler, or your automatic gate opener. At the same time, you can invest in larger systems to meet part of or all your home energy needs.
Some small electronic gadgets like music players, LED torches, and mobile phones come with little panels. On a large-scale approach, hundreds of panels can be installed to generate a large amount of electricity for towns and cities.
Whether solar energy is produced on a small-scale or large-scale system, there is always the need to take care of the excess power that is generated. Part of the energy that is generated during the day can be stored in a rechargeable solar battery for use at night.
How Does a Solar Panel Battery Storage System Work?
Solar panel battery storage systems work by converting the DC energy generated by the solar panels into AC energy that can be used to power the home. The excess energy is stored in the battery for later use. During peak hours or when there is no sunlight, the stored energy can be used to power the home.
Types of Solar Panel Battery Storage Systems
There are two main types of solar panel battery storage systems: AC-coupled and DC-coupled.
AC-Coupled Solar Panel Battery Storage System
An AC-coupled solar panel battery storage system is an independent system that is installed alongside the existing solar panel system. The energy generated by the solar panels is converted into AC energy and stored in the battery for later use. This type of system is flexible and can be installed on both new and existing solar panel systems.
DC-Coupled Solar Panel Battery Storage System
A DC-coupled solar panel battery storage system is a system that is integrated with the solar panel system. The energy generated by the solar panels is converted into DC energy and stored in the battery for later use. This type of system is more efficient than AC-coupled systems as it eliminates the need for DC-AC conversion.
Factors to Consider When Choosing a Solar Panel Battery Storage System
When choosing a solar panel battery storage system, it is important to consider the following factors:
Battery Capacity
The battery capacity is the amount of energy that the battery can store. A higher battery capacity means that more energy can be stored for later use.
Efficiency
The efficiency of the solar panel battery storage system refers to the amount of energy that is lost during the conversion and storage process. A higher efficiency system means that less energy is lost and more energy can be stored for later use.
Price
The price of the solar panel battery storage system should also be considered. It is important to choose a system that fits your budget and provides good value for money.
Brand Reputation
The brand reputation of the solar panel battery storage system is also important. It is recommended to choose a reputable brand that has a good track record of providing quality products and customer support.
