Residential solar storage is one of the keys to increasing the use of solar energy. Solar storage, provided by battery systems, makes energy produced during sunny days available so that it can be used at night and on days when sunshine is limited.
Using current technology, it’s possible for homeowners to customize the residential solar power system so that the solar energy they generate can be used in emergencies. To get the best coverage, a qualified solar consultant can help.
Here are a few things to consider in designing a residential solar storage (battery back-up) system
- How much capacity does each battery provide, or how many kilowatt hours of energy can be stored?
- What is the batteries power rating? This tells you how much power the battery can deliver at one time.
The answer to these two questions is used to determine how many batteries are needed to reach your goals. Residential solar batteries are designed to be highly customization to individual needs. For example, if your goal is to keep a few crucial appliances running for a long time, then your residential solar storage system should have higher capacity and a lower power rating. However, if you need to keep all your appliances running for a short time, then lower capacity and a higher power rating would be recommended.
An additional factor to consider in designing your residential solar storage system is the depth of discharge (dod) of the batteries. Dod is shorthand for how much of the battery capacity will be available. The depth of discharge also determines how long your batteries will last before they need to be replaced. The dod of the batteries in your system are a critical factor in how well your system meets your needs.
In designing your system, your solar consultant will provide you with choices that match your goals, along with information about expected life of and warranties for all components in your system.
In 2017, much of the research related to solar power generation is aimed at reducing the cost of storage of solar generated power. The Austin SHINES program is part of that effort. Of course, SHINES is an acronym – it’s shorthand for Sustainable and Holistic Integration of Energy Storage and Solar PV. This initiative, funded by the Department of Energy, is aimed at improving storage and other technologies so that Texas and other states can take advantage of their abundant solar resources. The potential for our state is huge, with most cities across the state receiving approximately 200 days of sunshine per year.
Get started now in taking advantage of that abundant energy by scheduling a solar consultation.
