Residential Solar and the Need for External Battery Backup

Solar power in the residential market is a growing trend, and more and more homeowners are taking advantage of solar energy. It is easy to understand why the idea of using the sun to help power your home sounds appealing. The price of installing solar panels has declined dramatically over the years, and a solar panel installation can provide a homeowner with fossil fuel-free energy for their home for about 20 years or more. As a result, it is not uncommon for homeowners to consider getting a solar energy system for their homes. However, many believe they do not need a battery backup because they have natural gas or other backup power.

Complete Residential Solar System and a Battery Backup

If you are thinking about getting a solar energy system for your home, you need to ask yourself if you want to be reliant on the power grid or if you want to be self-sufficient. If you want to be self-sufficient, then you should consider getting a battery backup for your solar panel installation.

A complete residential solar system includes all the components needed to generate electricity from the sun's rays. The most common components include photovoltaic panels, an inverter and mounting hardware for the panels. You will also need a battery bank to store extra electricity during daylight hours so you can use it at night or on cloudy days. This is where battery storage comes in handy!

The Need of a Battery Backup  

The battery is a buffer for excess solar energy generated during the day. When the sun goes down, this stored energy can be used to power your appliances and electronics. That means no more paying to have your grid power turned on at night and no more worrying about whether or not there will be enough electricity for all of your devices.

The battery also acts as a backup if disruptions in your grid power supply, like brownouts or blackouts. If those occur, your battery will keep powering your home so that you do not lose access to your house's lights, heaters, and other essential appliances.

For example, if you have strong winds during summer but little sun in winter, batteries can smooth out this difference by storing the excess energy produced during summer and releasing it at night when no sun is available.

Choosing the Battery Backup for Your Residential Solar Panel System 

Many different types of batteries can be used for solar energy storage, including lead-acid and lithium-ion batteries. Lithium-ion batteries are the most popular choice because they are more efficient and last longer than other batteries. They also discharge electricity at a high rate, which means they can charge up quickly when needed and discharge soon when required.

Lead acid batteries may seem like a better choice at first glance because they take up less space and weigh lighter than their lithium-ion counterparts. But in reality, there are many other benefits for choosing the latter over this type of battery including more durability as well as improved performance when applications require higher currents or greater discharges from your device's electrical system

The key difference between these two popular types lies mainly within how much power each can produce before breaking down; however it isn't always so straightforward since both have drawbacks too!

Moreover, the best battery storage system for your home will also depend on several other factors, including:

  • The size of your home
  • How much power do you need to store
  • The number of days you want your system to run without sun or wind power
  • The amount of money you want to spend on the project

The Key Takeaway 

The future is here, and it's solar-powered! The idea that we can harness the power of nature and make our lives more eco-friendly is not new, but it's just coming into its own. Storage batteries provide an essential service when working in combination with solar panels by helping homeowners store energy for when they need to use it most - like during those cloudy days or at night time.
