Energy Storage


Ipsun Solar provides home battery storage solutions for the residential and the commercial market. Paired with solar, a system for storing energy can let you truly use your solar all the time, dramatically reducing reliance on fossil fuels and the grid.

Tesla Powerwall Certified Installer

Ipsun Solar is now a Tesla Powerwall Certified Installer, currently the only one in DC and VA.  As such, we bring customers a customized solar-plus-storage solution. With Powerwall you can store solar energy generated during the day for use any time. During the day, the sun shines on your solar panels, charging your battery.

At night, your home draws electricity from your battery, powering your home with clean, sustainable energy 24/7. Installing Powerwall with Ipsun Solar is easy. We take care of everything from system design, permitting, installation, financing, and app how-to.

Powerwall consists of a 14 kWh lithium-ion battery pack, liquid thermal control system, an integrated inverter and software that intelligently dispatches electricity when it’s needed most. The unit mounts seamlessly on a wall or on the ground, indoors or outdoors, and is connected to the grid to export excess energy, maximizing your opportunity for economic benefit.

Storage solutions can meet a few different kinds of energy goals. The most common purpose for battery systems integrated with solar energy systems are:

  1. Backup Power: A grid-connected system that can be turned into an off-grid micro-grid when the utility grid is down. Responding quickly and automatically to outages, a battery storage system involves less noise than a generator and no expensive fuel or exhaust.

    For many utility customers, batteries add value for grid-connected solar
  2.  Anti-Export: Some utilities charge more for the energy you pay than they can pay you for your excess solar power at times when you’re using less than you’re producing. In this scenario, it makes sense to avoid “exporting” solar to the grid, so the customer can configure a backup battery system to store surplus solar power to use a later time – after all, it’s worth more to you to use than it is to contribute to the grid if you can’t get retail rate for it!
  3. Time of Use: If the utility charges peak prices, use a storage system to charge a battery system from the grid when electricity from the grid is cheap and use the power stored in the batteries when the price of electricity from the grid is high. Several localities require the power generated from a solar system to be used onsite. A battery system is then designed to store solar power generated during the day and consume it in the morning or the evening.

There are many types of batteries on the market. These vary in both the chemicals they use (and their safety factor and weight related to their chemistry) and in the target applications they are used for, whether grid tied or off-grid.

Energy storage means taking full advantage of the solar energy system you love, throughout the day and year:

  • Rather than using utility energy from fossil fuel and nuclear sources part of the time, you can actually use your own solar virtually all the time. Looking to be 100% renewable? A battery is essential so you can store any surplus solar power and keep from sending any of that good solar energy to the grid.
  • True self-sufficiency and energy autonomy
  • Did you know that the 30% federal tax credit that solar has also covers battery backup systems used for storing solar? Now you know!
  • Skip the noise and smell of a generator. (Full disclosure: There are some models of battery that emit a beep or ping, make switching sounds, and have a fan running that makes a sound comparable to a running fridge. But honestly, we just place these away from your main living areas and it’s a lot better than a rumbling generator!)
  • Warranty on the system and installation labor


Did you know that Maryland offers an energy storage tax credit? It’s valued up to $5,000 in incentive dollars and applies as long as the battery is at the taxpayer’s primary residence. Learn more about the homeowner and non-residential energy storage incentives in Maryland. Read about including your energy storage installation purchase in your federal solar tax credit filing as well! (We do not give tax advice, so we recommend seeing your accountant.)


Commercial battery energy systems are a great idea, and they can just be a little more complex than residential energy storage systems. That’s why for commercial storage services, we recommend you talk to us directly:
