Welcome to Helios Solar Systems, LLC

Helios is founded on the principle that the future of solar is now!

Solar for homes is becoming more and more popular. The technology is now quite straightforward; put solar modules on your roof, and the sun’s energy is directly converted into power for your home – which offsets the amount of electricity otherwise purchased from the power company. Each year the price of electricity goes up and the price of solar goes down. Mix this trend with local and federal incentives, and a positive return-on-investment is easily achieved. In some states, over time, the return-on-investment rivals what you could expect from a decent mutual fund. Additionally – you have the satisfaction of doing the “right thing” for the environment. Unlike coal and natural gas, solar produces no greenhouse gases.

If solar is right for you, what are you waiting for?  Get Started now!

Historically, it has never been better than right now. In the past, solar was too expensive, and grid power was cheap. Not now. In the future, the Government incentives will likely go away.

Our company offers engineering consulting, project management, and contracting services to the Solar PV community. We service residential, commercial and government customers in the Maryland, DC, and Virginia areas. We seek to help customers answer the following questions:

  • Will Solar work for me?
  • Does Solar make economic sense?
  • What is “Net Metering” and when is it allowed?
  • What are the design and product choices?
  • How do I get Permits?
  • How can I find an Installer?
  • Can I Do it Myself (DIY)?
  • How do I obtain Government incentives?
  • What Are Solar Renewable Energy Certificates (SRECs)?
  • How do I know if my system is working correctly?
  • Should I use stand-alone solar or grid-tie?
  • Should I have batteries for back-up power?


I was impressed with the organization of materials, tools and the prominent display/use of the engineering documents Helios drafted specifically for our job. Professional, organized, prepared to expend special effort as necessary and readily responded to my questions… we were reassured by the fact that the work was managed by Tim, a PE, PMP and a NABCEP Certified Solar Energy Professional.
- Larry Williams, Hamilton, VA
Tim’s design was very elegant using frameless, all black modules that matched well with the roof. No wires or mounting equipment is visible and the shape of the array matches the roof line very nicely. After sale support is excellent. Tim is always available for questions and is very knowledgeable and responsive!
- Sarah A., Leesburg, VA
Tim’s designs made permitting a snap. The system works great!
- Peter Clay, Falls Church, VA
Going down the DIY solar route was a fun and rewarding experiencing, but it wouldn’t have been possible without Tim’s engineering and design drawings.
