Going solar for your energy needs is a smart choice. However, the solar system works only during the day time. i.e itt only produces electricity when there is sun light. so in the night time and cloudy days, you have to look for other alternatives of solar or a system to store the energy produced from solar panel to use during requirement.
Battery backup comes to your help in this scenario. The energy sotred in the battery will power your home during blackouts caused by severe weather, or during grid outages due to increasing demands on our aging infrastructure or during maintenance periods of the solar system.
In addition, you can be more independent from your local utility service providers with a solar connected battery system.
Before you begin to look for solar batteries consider the following Two Things
1. Consider the conditions under which your battery must work and the types of batteries that are available in the market today. So that you can replace the batteries easily. Also check for the standard operating conditions specified in the battery to match with your ambient conditions.
2. Calculate the power needs of your home with your solar technician to decide the right battery capacity and the technology.
Batteries and Solar Systems
Batteries and solar systems work together to effectively manage several conditions:
- Unstable Grid Energy: Many utility companies have blackouts or unforeseen power surges that zap your neighborhood of energy. (It’s becoming common.) Your solar battery should kick-in and run power to your home so the lights stay on and you stay connected to the community.
- Heavy Cycling: Your solar battery will charge and discharge during use. The term “charge cycle” is used to specify a battery’s expected life. The number of cycles affects how long it will last as time goes on.
- Irregular Full Recharging: What happens to your solar system if the battery is not fully charged on a consistent basis? You need to count on using its backup energy when you need it. Make sure your battery works for you and delivers power to your home when you need it.
Three Common Types of Solar Batteries
As you do your research, you’ve probably heard of the following common battery types:
- Lead-acid batteries : This older battery technology has been used in renewable energy for a long time. These batteries could be a good option for homeowners who want to go off the grid and are relatively low in cost.2 “Off-the-grid” is for homeowners who can’t rely on a local utility.
- Lithium-ion batteries : Most homeowners want to, and need to, stay connected to the grid. Current research from the “US Energy Storage Monitor 2017” report indicates lithium-ion batteries dominating the market.3 Although a bit more expensive, it is the most popular battery for homeowners due to its superior performance and reliability with your local grid.
- Flow batteries : This type of battery is the newest option for solar storage. They don’t degrade over time, so they can last much longer than other types. But its complex chemistry often requires additional energy and cost. This battery could be a good option in the future but currently, lithium-ion is the clear winner.
Understand Your Power Needs
Again, it’s important to understand your power needs when going solar. Always try to go for a customized design for your house or building when opting a solar solution as the solar energy output will vary significantly depending upon the area available, direction of the panels, design or architectural limitations.
We can help you design a customized solar solution just for your need and help you choose a battery big enough to handle your future energy needs, and we handle the process from start to finish.
