Expanding Solar Energy Value and Versatility

Battery Storage Allows You to Use Energy Later

What Energy Storage Does for You

As a solar energy system generates power each moment it must either be used by the home or immediately transmitted to the grid. Most rooftop solar installations are designed this way, and for the most part the grid acts as a battery. Some might describe it as a deposit bank for the solar energy, allowing withdrawals at a later date. 

With local energy storage, the momentary excess power can be kept without being transmitted. At SunRa Solar, we supply battery based storage by a range of manufacturers to satisfy different homeowner needs and goals.

More About Solar with Battery Storage

There are many large scale experimental grid energy storage projects under way across the globe using unique and novel chemical, thermal, and other energy storage technologies. For residential solar + batter storage systems SunRa Solar selects designs using lithium-based batteries for two reasons. They are tried and true, therefore very dependable. And they are in widespread use, making them relatively economical.

Battery Storage in Action

Residential battery storage works in a way very similar to a car’s starting battery. Charging can continue until each battery is 100% charged up.

In your car, your system’s alternator network responds to make sure the battery isn’t overcharged, reducing output as required. In a similar way a charge controller circuit in a solar + storage system simply redirects the unneeded solar energy to be transmitted to the grid. That is the advantage of being grid-connected. Every kWh of solar output is either used by the home, used to charge batteries, or transmitted to the grid to be used by neighbors, so to speak.

As you use power stored in batteries, any excess solar energy not needed to power the home may be used to recharge the network. This cycle continues automatically and as needed.

Battery Storage Uses

At this moment in Massachusetts, utilities do not penalize homeowners for their time-of-use of purchased power. However, the store-now-use-later nature of battery storage is vital for making a home resilient to storms and outages. And for homeowner looking for the lowest environmental impact, having the ability to generate more solar power and use it later to further reduce their utility demand can be a smart investment.

Security During Outages

Power outages occur more frequently as the energy grid continues to age. If you already have solar, you’re way more prepared than the average homeowner. Batteries allow you to expand your energy security around the clock. This is typically referred to as "backup" energy supply.

Elective Use of Solar Power

There can be a number of reasons a household may prefer to use stored solar energy during periods where the solar energy system is not generating at a level to cover all local demand. Battery storage adds the flexibility to shift the time and use of some amount of the generated solar power.

Adding Storage Means Designing It Into the System

Getting the most from your local battery storage requires more than simply adding on the hardware. SunRa Solar provides comprehensive solar plus battery storage designs. Working directly with each homeowner, we understand your goals and needs and ensure the system will provide you the power when you want it, and as safely as possible.
