Red Sun Weekly: 2016.08.12

Red Sun is Solar Powered (and Networking…)

The past few weeks have been all systems go at Red Sun. Evan (our CEO) and Dave (our COO), are running around the DMV area, attending networking and business development events to expand our network and capabilities.

Our work with Nishati has continued as well. Together we are looking at new ways to make solar energy technology even more accessible to people by providing information and practical uses for solar panels. One thing we are excited about, is integrating solar power into Internet of Things devices for remote sensing and for use in conjunction with small computers like the Raspberry Pi.

Are you curious about how solar panels generate power from sunlight? We will be providing an in depth review, but in the meantime, check out these cool facts below about solar energy production.


Weekly Highlights

Solar Irradiance

Solar power is generated by exploiting energy contained in sunlight. Power from sunlight is measured by the amount of power produced from electromagnetic radiation per unit area (Watts per square Meters). This measurement is referred to as Solar Irradiance and can be measured by a Pyranometer.


What the hell is a Pyranometer? A Pyranometer is a device that measures Solar Irradiance. Its name comes from Latin Pyr (meaning “fire”) and Ano (meaning “sky/above”), so essentially it’s a device to measure “Sky Fire.”

There are three types of Pyranometers, one uses Thermopile-based technology for measurement and the other two use less accurate Silicon-based technology.

Thermopile Pyranometers are the most sensitive devices, providing the greatest range of solar irradiance wavelength detection across 300-2300 nm.

Photodiode-based Pyranometers (also known as Silicon Pyranometers) use a photodiode to detect wavelengths from 350-1100 nm.  

Photovoltaic Pyranometers, a variation of Photodiode-based sensors, are based on solar panels and provide wavelength detection across ranges from 350-1150nm. These sensors are sometimes referred to as “reference PV cells” in studies.

By measuring Solar Irradiation, we can determine where good locations to place Solar Panels are. By using a pyranometer to measure Solar Irradiation against electrical current generated by a solar panel in the same location, it is also possible to measure the efficiency of a solar panel.

Hope you enjoyed these bits of info!


CEO Notes

The American entrepreneurial dream is growing a new idea out of a garage and through a Hollywood montage – ending up on a TED talk stage. This is a romanticized view of small business development, and while Red Sun is currently developing out of small apartments and hookah bars, we aren’t expecting the montage of success to occur without consistent effort, continuous learning, and external engagement.

Talent plus luck equals success. Our goal at Red Sun is to organize and prioritize our talents and efforts; while simultaneously maximizing our luck. This is done by increasing our odds through networking and making new connections.

Much of our effort over the past few weeks has been devoted to networking. I, along with Red Sun COO Dave, attended meetings at the Arlington Economic Development Council, Government contracting events, and will soon be meeting with new colleagues in DC, Arlington, and Baltimore.

Stay tuned over the coming weeks as we develop projects from these engagements. If you are a business looking to integrate open source technology, IoT devices, or expand your market by accessing international markets and localization expertise, contact us at
