We help you save the planet, spend less & generate your own power with custom build solar panel solutions for your home or business

Ipsun Solar is inspired by a Latin word meaning “your own.” Why are we called Ipsun? We install solar panels allowing anyone to generate their own power.

The energy status quo goes like this: Customer gives money to the electric utility each month for power that is mostly from fossil fuels. Coal and gas power have consequences that are harmful to our communities and the environment.

Ipsun Solar offers the ability to make a quick, easy change: By producing your own power from solar, you will lock in low electricity costs from a cleaner source of energy, and you will add value to your home or business.

Our Services and Territory

Ipsun Solar is a full EPC company. That’s engineering, procurement and construction of solar. We perform residential, commercial and utility-scale solar panel installations focusing on the Northern Virginia, Washington D.C. and Maryland area.

Getting work done to your property can be daunting. That’s why we pride ourselves on knowing the unique complexities of the solar industry and on designing custom-made solar PV systems for each client.

One of our co-founders is an electro-mechanical engineer. He designed one of the world’s first solar cars along with the Massachusetts Institute of Technology (MIT) over a decade ago. Rather than a one-size-fits-all solution, we use a flexible approach. No one should settle for less than custom solar.


We are a mission-driven company. What gets us out of bed every day is providing solutions to climate change, creating energy resiliency, and making lasting, meaningful impacts on our communities. Our company is growing fast, and we are a B Corporation! We are consistently reviewed well and rated highly for our integrity, honesty, and above all, a love for what we do.
