Smart Photovoltaic Windows
The high transparency and power output per unit area of ClearPower™ has garnered enthusiastic letters of support from major glass manufacturers for its promising technology within the photovoltaic industry.
The global market for Building-Integrated Photovoltaic (BIPV) windows is expected to grow significantly (16.0% CAGR) and is projected to reach $13B by 2028.*
Stellaris currently holds three patents for photovoltaic device technology and has accrued more than fifteen years of experience developing solar photovoltaic (PV) equipment, during which we became a national first prize winner of the Cleantech Open, the world’s largest clean technology accelerator program.

Stellaris Corporation is developing ClearPower™, a transparent, solar electricity-generating window technology designed to decrease or eliminate building emissions of greenhouse gasses from the use of fossil fuels for space heating.
As one of the first Building Integrated Photovoltaic Windows (BIPV) capable of providing both substantial power output as well as high transparency, ClearPower™ is positioned to be a powerful tool for electrifying buildings and reducing their dependence on fossil fuels. It is especially well suited for buildings in dense urban areas without sufficient space for solar or wind energy installations.

ClearPower™ is the culmination of more than fifteen years of work by Stellaris Corporation to address the urgent need for a way for buildings to generate their own clean electricity. Now, with testing from the National Renewable Energy Laboratory (NREL) corroborating our technology's performance and support for ClearPower's promising developments from international glass manufacturers, Stellaris is working towards an official commercial launch.
In 2020, the United States Environmental Protection Agency reported that buildings emit more greenhouse gasses than the transportation or power generation sectors. Buildings still rely heavily on fossil fuels for heating, yet as pressure mounts to reduce greenhouse gas emissions, many buildings, especially high-rise buildings, are left with limited options for obtaining green electricity to replace fossil fuels for heating. The need for so many buildings to have a source of clean electricity has created an urgent need for new clean electricity technology to enable buildings to self generate green electricity.
Existing photovoltaic windows have gained little traction due to their high cost, low power, and/or their lack of transparency. ClearPower™ addresses all of these issues with a power output approaching that of traditional high-efficiency, opaque photovoltaic (PV) modules, all while maintaining high transparency.
ClearPower™ solar photovoltaic windows use narrow photovoltaic cells embedded in a window glazing. Due to the small size and orientation of the cells, ClearPower™ maintains high transparency while its unique design enables the production of up to 5 times more power than other "clear" BIPV windows. Its electrical output approaches that of a conventional high-efficiency, opaque PV module. ClearPower™ can be used as building windows while generating greenhouse gas-free electricity to power the building’s heating and cooling needs.
*The above image features a ClearPower™ prototype. Product is not currently available for commercial use.
The integrated high-efficiency solar cells act as louvers, blocking high-angle sunlight which reduces air conditioning loads. This is a significant additional energy-saving benefit.
Stellaris plans to develop high-speed, automated manufacturing for the ClearPower™ PV panels, which we will then outsource to contract manufacturers. This scalable, low capital approach will allow us to avoid the expense of building our own facilities while retaining the ownership of the high value technology assets by patent and trade secret protection.
Around the country, laws are being passed by cities and states requiring both existing and new buildings to drastically reduce their greenhouse gas emissions by eliminating the use of fossil fuels for space heating, while building codes are prohibiting new natural gas hook-ups and requiring the inclusion of renewables for new buildings. With target dates for these ambitious goals only a few years away, many building owners and managers are feeling the pressure to find a solution.
Spurred by these regulations, the global market for Building-Integrated Photovoltaic (BIPV) windows is expected to grow substantially (16.0% CAGR) and is projected to reach $13B by 2028. Sized at $4.6B in 2021, Stellaris sees the nearly 3x market growth projection as validation of our technology's role within this renewable energy push.
Stellaris is targeting new construction and replacement markets both domestically and internationally for large-insulated glass windows, especially high-rise buildings with curtain-wall construction. We also see an immediate benefit for related applications such as clear railings and clear barriers.
We are truly excited about the latest iteration of our ClearPower™ design, as it’s already beyond what we hoped for when it comes to transparency, appearance, and performance - and other industry organizations share this sentiment.
*The above image features a ClearPower™ prototype. Product is not currently available for commercial use.
Major glass manufacturers have shared their support for the ClearPower™ product due to its high transparency and power output per unit area, one citing it as a "promising technology" for the BIPV industry. Additionally, the National Renewable Energy Laboratory (NREL) has conducted independent tests of the ClearPower™ product that have corroborated Stellaris’s own performance testing.
Stellaris currently holds three patents for photovoltaic device technology with additional patents pending, in addition to the extensive know-how and trade secrets we have learned over 15 years of developing solar equipment. During this time, Stellaris also became a national first prize winner of the Cleantech Open, the world’s largest clean technology accelerator program.
Stellaris believes ClearPower™ can play a critical role in the fight against climate change by reducing greenhouse gas emissions. As many building owners are facing legally mandated deadlines to decarbonize their buildings and regulations that require termination of the use of oil and gas for building space heating, we feel the timing is perfect for the introduction of our ClearPower™ solar photovoltaic window into the market.
Funds raised from this campaign will be used to continue refining our product for commercial production, develop automated assembly procedures, manufacture and install ClearPower™ at test and beta sites, and continue to test the performance and durability of the product and to make continuous improvements in the product’s design and efficiency.
With help from the StartEngine community, we are determined to make Stellaris Corporation a go-to provider of clear, electricity-generating window components. Invest today in a scalable, cost-effective technology and join us as we seek to make a worldwide impact.

Stellaris is developing ClearPower™, a fully-transparent, electricity-generating window. With its high power-density and transparency, ClearPower™ is uniquely designed to meet the urgent need for buildings to generate their own green electricity and stop using fossil fuels for heating. Our goal is to enable every window to be a power plant. Stellaris is currently pre-revenue and its technology is patent-pending and not yet available for commercial use.

The Inflation Reduction Act (IRA) provides investment tax credits for projects and products that generate electricity from solar energy. This would include Stellaris’s ClearPower™ photovoltaic (PV) windows. The tax credits can be as high as 30% of the cost of the purchase and installation of the solar photovoltaic window, increasing to as high as 50% of the cost of the PV windows for certain installations. Note that the tax credits apply to the whole window and its installation cost, not just to the photovoltaics inside it.
In addition, the IRA provides substantial bonus and accelerated depreciation for renewable energy generation and energy efficiency retrofits, which would include solar PV windows.
The bottom line is that the IRA may pay for most or all of the additional cost of making windows electricity-generating, meaning that buildings across the country could benefit from years of generating their own electricity for free! Photovoltaic windows should be a “no-brainer” for all retrofits and new construction.
Peter has always been a tinkerer, modifying things for other uses or improvements. Recumbent bicycles, water bicycles, windmills, off grid solar installations, various Arduino controlled “things”, sailboat modifications (“Bilge Yoga” in the bowels of his ketch sailboat, see photo), are all things on the fun to do list.
Working as a Machinery Engineer has been a natural extension of all the side projects. Peter started in the food industry, repairing and designing food processing equipment, moved into film processing equipment, and later to photovoltaic cell processing equipment. Peter has designed, built, and debugged all types of machines, from cam driven motions to vision guided motions to assist manufacturing. He is always learning new things and either bringing this expertise in to work or back to the home workshop for further fun.
Peter has a BSME from Tufts University, has also learned on his own; CAD (prefers Solidworks), sheet metal bending, and other fabrication techniques, some simple electrical engineering , and various programming languages.
Rob has spent his professional career developing processes and building equipment for the photovoltaics industry, as well as shorter stints supporting instant photography and computer manufacturing. Most recently he helped found solar module manufacturer Evergreen Solar, co-founded photovoltaic test equipment manufacturer BrightSpot Automation, and established his own engineering consulting business. Rob has done a variety of engineering and management projects supporting solar crystal growth, cell fabrication, and module fabrication.
Rob is a mechanical engineer by training. He has BS in Engineering and Applied Science from Yale and a MS in Mechanical Engineering from MIT. His MIT Masters thesis was a computer model of film-cooled gas turbines used for combined cycle power generation. (He abandoned fossil fuels after graduation.) Rob has an innate curiosity about all things mechanical - every year he attends the Model Engineering Show in Boston to see small scale working models of all sorts of mechanical devices, and perhaps most importantly, to grab a beer with some of his techno-buddies.
For fun, he enjoys woodworking and boating, both of which are embodied by the boat in the photo above that Rob built. Note the low carbon footprint. In addition to oars, the boat can be powered by a jib and sprit-rigged mainsail.
The California Air Resources Board on Nov. 16, 2022 issued its Scoping Plan to decarbonize California. For buildings the plan is to achieve nearly zero carbon emissions through 100% electrification. This will greatly expand the potential market for Stellaris’ solar PV windows in the largest state in the US. Highlights of the CARB plan:
In sum, all new and existing buildings in California will eventually have to be 100% electric. This will pave the way for a huge market for solar photovoltaic widows to self- generate the building’s electricity and reduce the building’s electrical load and greatly increased electricity costs.
Also see, LA Times Article:
If that isn’t enough to generate a market for solar PV windows, in August 2022 the California Energy Commission adopted an updated Energy Code for new and renovated buildings to permit the state and local governments to require use of heat pumps, solar energy and battery storage to 100% electrify and decarbonize buildings.
Moreover, the City of Los Angeles has proposed to ban natural gas in new buildings. See, https://www.spglobal.com/marketintelligence/en/news-insights/latest-news-headlines/los-angeles-proposes-natural-gas-ban-in-most-new-construction-72375727
At least 57 cities and towns in California have already enacted ordinances to require zero carbon emissions in new buildings or require 100% electrification in new and renovated buildings. See, CIQ Pro: Gas Ban Monitor: East Coast policies advance; Pa. gas ban prohibition fails (spglobal.com)
The requirement for 100% electric buildings is rising into a tidal wave across the US. For example, the State of Washington will require heat pumps in its residential building code, banning use of fossil fuels for space heating. See: https://www.sbcc.wa.gov/sites/default/files/2021-06/2021%20WA%20Code%20Change%20-%20Heat%20Pump%20Space%20Heating.pdf
New York City has already required zero carbon emissions for new buildings, see https://www.urbangreencouncil.org/content/projects/all-about-local-law-97, and many other cities are following its lead.
The result will be to create a huge new potential market for Stellaris’s ClearPowerTM solar photovoltaic windows.
Stellaris is very excited and intends to become the standard for the new building industry across the U.S and internationally.
Stellaris very much appreciates your isupport and interest in its crowd funding campaign.
Stellaris will be enhancing its R&D capabilities next week when it moves into the Millyard Technology Park in Nashua NH. The new, additional space will greatly assist us in making ClearPower components in larger volume, developing automated assembly procedures, and providing enhanced resources for testing.
The Millyard Technology Park is an exquisitely renovated, 150,000 square foot former textile mill that is home to a robust and eclectic collection of high-tech companies and offices.

How much can I invest?
With Regulation A+, a non-accredited investor can only invest a maximum of 10% of their annual income or 10% of their net worth per year, whichever is greater. There are no restrictions for accredited investors.
With Regulation Crowdfunding, non-accredited investors with an annual income or net worth less than $124,000, are limited to invest a maximum of 5% of the greater of those two amounts. For those with an annual income and net worth greater than $124,000, he/she is limited to investing 10% of the greater of the two amounts.
When will I receive my shares?
At the close of an offering, all investors whose funds have “cleared” by this time will be included in the disbursement. At this time, each investor will receive an email from StartEngine with their Countersigned Subscription Agreement, which will serve as their proof of purchase moving forward.
Please keep in mind that a company can conduct a series of “closes” or withdrawals of funds throughout the duration of the campaign. If you are included in that withdrawal period, you will be emailed your countersigned subscription agreement and proof of purchase immediately following that withdrawal.
What will the return on my investment be?
StartEngine assists companies in raising capital, and once the offering is closed, we are no longer involved with whether the company chooses to list shares on a secondary market, or what occurs thereafter. Therefore, StartEngine has no control or insight into your investment after the close of the live offering. In addition, we are not permitted to provide financial advice. You may want to contact a financial professional to discuss possible investment outcomes.
Can I cancel my investment?
For Regulation Crowdfunding, investors are able to cancel their investment at any point throughout the campaign up until 48 hours before the closing of the offering. Note: If the company does a rolling close, they will post an update to their current investors, giving them the opportunity to cancel during this timeframe. If you do not cancel within this 5-day timeframe, your funds will be invested in the company, and you will no longer be able to cancel the investment. If your funds show as ‘Invested’ on your account dashboard, your investment can no longer be canceled.
For Regulation A+, StartEngine allows for a four-hour cancelation period. Once the four-hour window has passed, it is up to each company to set their own cancelation policy. You may find the company’s cancelation policy in the company’s offering circular.
Once your investment is canceled, there is a 10-day clearing period (from the date your investment was submitted). After your funds have cleared the bank, you will receive your refund within 10 business days.
Refunds that are made through ACH payments can take up to 10 business days to clear. Unfortunately, we are at the mercy of the bank, but we will do everything we can to get you your refund as soon as possible. However, every investment needs to go through the clearing process in order to get sent back to the account associated with the investment.
What is the difference between Regulation Crowdfunding and Regulation A+?
Both Title III (Regulation Crowdfunding) and Title IV (Reg A+) help entrepreneurs crowdfund capital investments from unaccredited and accredited investors. The differences between these regulations are related to the investor limitations, the differing amounts of money companies are permitted to raise, and differing disclosure and filing requirements.
