Why storage?

You’ve got the power. Don’t let it go.

Control where you get your power, when you use it, and how much you pay for it. Storing energy in Aquion’s Aspen batteries enables you to use solar energy at night, consume all the solar energy you produce, and control your energy costs.

Our environmentally-friendly solar batteries are optimized for daily deep cycling and provide robust, reliable performance with no maintenance requirements. Our batteries can also provide backup power during storms and outages to ensure that you have critical power when the grid is down.

How batteries can make a difference in your home.

Solar Self-Consumption

Capture all the solar you generate, and maximize the return on your clean energy investment.

Many grid-tied homeowners with solar panels end up relinquishing clean power they’ve generated back into the grid – power that they could be capturing and storing for themselves.

Our solar batteries let you store excess energy generated by wind and solar so you can use it when the sun is not shining or the wind is not blowing, maximizing your use of solar energy and reducing your reliance on the grid.

Backup Power & Islanding

Create your own backup plan for when the power goes out.

When Hurricane Sandy struck the East Coast of the United States in 2012, many people lost grid power. Those with grid-tied solar were surprised to find that they were unable to use their solar when the grid was down.

For backup power during grid outages, you need a system that includes batteries and an inverter with islanding capability. This type of system design allows you to keep your home powered and safe, even when the grid is down.

Time of Use Optimization

Control when you use grid power, and how much you pay for it.

Depending on where you live, you may pay variable energy rates based on time of day and time of year. The general rule here is that energy costs the most at the times of highest demand. While you could do laundry in the middle of the night or not run your AC during the hottest time of day to save money, it’s a lot more convenient to to use energy when you need it without worrying about time of use costs.

Batteries can silently and efficiently charge overnight from the grid when energy is the cheapest, and then you can use the energy stored in the battery during the highest-cost daytime hours.

Demand Charge Reduction

Avoid demand charge penalties from your utility.

In some areas, utilities apply a demand charge when homeowners exceed their peak power limit.

These demand charge penalties are often so onerous that even if you only exceed your peak power limit one time in the course of a billing cycle, you are penalized by having to pay a higher rate for the entire billing cycle.

In these situations, you can use a battery system in order to monitor the power that your home or business is pulling from the grid and dispatch power from the battery to keep you below this peak power threshold. Doing this can prevent demand charges on your utility bill and save you money at the end of every month.
