The World Needs a New Paradigm of Power

Electric utilities, significant contributors to climate change, cannot support the amount of renewable energy required for a clean energy future. Various studies put the necessary investment for getting the world's electrical grids ready for the all-renewable future in the trillions of dollars (Source).

Utility Upgrades for an All-Electric Home Are Expensive for Consumers. 
Many modern all-electric homes will require over 400 A of utility service. Most existing homes have 100-200 A service. Service upgrades by utilities are expensive, as the above cost estimation by the California utility PG&E shows. Even if the utility upgrade is on time and budget, the customer is still exposed to an unreliable grid, has little or no choice over the source of the electricity, and is captive to utility rates. In contrast, a PowerBloc can deliver reliable and green power equivalent to up to 800 A of service with fixed energy cost for decades to come.

Also, today's centralized power grids cannot withstand increasingly frequent weather extremes caused by global warming, and they are prone to preventive shutdowns in wildfire areas and flood zones.

The Power Grids Are Vulnerable to Wildfires Caused by Extreme Droughts. 
In Northern California, such as here near Fairfield, wildfires have destroyed power lines, leading to power outages. Outages also occur when the local utility turns off power during high winds to prevent power lines from sparking wildfires.

We need a new paradigm to deliver reliable and carbon-free electricity to everyone. We believe that solution must be a primary power supply with little or no reliance on utility power and outside the control of utilities. The YouSolar PowerBloc® is such a system. It is a fully-integrated and intelligent solar nano-grid that powers an entire home or business and requires no utility approval.

Meet the Modular PowerBloc® . The PowerBloc comprises modules for different functions. The above animation provides an overview of all modules. Modularity delivers ultimate flexibility in configuration and size and is ket to PowerBloc's success in the market.

The PowerBloc is modular and highly scalable. All of its components – batteries, chargers, controllers and power electronics – are efficiently arranged in a rack. The configuration can be easily customized and expanded to meet customers' growing needs.

(During the demonstration, the front doors of the PowerBloc were removed. There are no dangerous high electric potentials in the front of the system.)

To accelerate sales and take the PowerBloc global, we have designed and patented stackable modules that are uniquely plug-and-play. These modules will make the system easy to ship and even easier to assemble. This innovation also allows rapid deployment of the PowerBloc by disaster relief organizations or the military. We believe the stackable PowerBloc will be a game-changer.

The Problem

Complicated Solar Systems That Depend on the Grid

Today’s residential solar and battery systems are a mix of legacy and new technology that were not designed together and depend on stable grid power to function. All leading solar-battery systems are grid-tied and require utility approval, making incumbent utilities the gatekeepers of the entire solar industry. This is not the blueprint for a paradigm shift, especially in critical international markets where unstable grids cause technical problems for grid-tied systems and where utilities view distributed solar as a threat to their business.

The Electrical Systems in Many Emerging Markets Are Already Overloaded. 
The electrical systems in many emerging markets are already overloaded and fairly frequently. Imagine installing a 10kW Level-2 electric vehicle charger in a home connected to the power system in Old Delhi, shown above. It will break the grid. Residential independent primary power systems, such as the PowerBloc, are the answer.

These solar-battery systems have little flexibility and very limited scalability. They are primarily designed for energy arbitrage and use simple algorithms to manage power outages. Installation requires trained personnel with tools and dollies and lift jacks to handle large and heavy batteries.

The solution

A Fully-integrated System that Works Independently of Utilities

The PowerBloc® is a fully-integrated nano-grid using a proprietary and patented power architecture. The PowerBloc is modular and highly scalable. By design, the PowerBloc is the primary electricity supply to a home or business, while the utility just serves as the backupTo be a primary power supply, the PowerBloc’s inverter creates AC power that energizes an independent grid for the house.

PowerBloc Modules Are Easy to Transport. PowerBloc® modules, or “blocs,” in a crate on their way to a customer installation. On-site, the modules are installed into the cabinets by hand. The modular nature of the PowerBloc makes dollies and lift jacks unnecessary.

The PowerBloc can also incorporate and store energy from the grid, a generator, or any other electric power source. All power sources blend seamlessly on the efficient high potential direct current bus that is the core of our patented power architecture. YouSolar sends a real-time hourly solar production forecast to each PowerBloc so that its energy management system can make intelligent decisions optimizing its use of solar energy. 

The PowerBloc® Nano-Grid is Highly Scalable.

The picture above shows a four-cabinet PowerBloc with 110kWh of energy storage, 30kW of solar, utility and generator integration. This image is an engineering rendering of modules and cabinets used in customer installations.

For customers with a utility connection, the grid contributes only energy to the PowerBloc but does not connect, directly to the load. Therefore, there are no glitches when the grid goes down, and the PowerBloc operates as an off-grid system wherever there is no grid. It’s as simple as that.

Our Customers Find the PowerBloc's User Interface Intuitive. The Power Flow screen shows how power blends seamlessly on the nano-grid. The image shows a screenshot of the tablet user interface.

YouSolar delivers sustainable and affordable power for the modern world. Customizable and scalable, the PowerBloc is a private power system that meets many needs and can be connected to the grid or off-grid. The PowerBloc can integrate any generator to “extend the range” of the batteries on cloudy winter days.

Due to the modular design of the PowerBloc, customers can start small and expand their system as their needs grow without any design changes. This is particularly important in emerging markets, where power needs change with rising incomes.


Our First Market Is High-End Homes in California

YouSolar has sold and installed six residential PowerBloc®s with customers in California's wine country. We also have two off-grid systems operating in Big Sur and the Sierra Nevada, CA.

Our First Customers Are Owners of High-end Homes in Northern California. These homes are subject to frequent power outages because the local utility can no longer deliver reliable power and because the threat or presence of wildfires requires shutting down the electric service.

Our customers are affluent, self-reliant, and uncompromising homeowners. They are unwilling to tolerate power outages and want a reliable and clean power supply with little or no reliance on utility power. They are building all-electric homes with electric vehicle charging and want to avoid paying tens or even hundreds of thousands of dollars for a utility upgrade or new connection.

These Are Modern Homes with Large Electric Loads. Our customers have central air conditioning systems, electric stoves and ranges, pools, electric vehicle charging, and often well pumps which are large electric loads requiring high power.

The PowerBloc Is a Fully-integrated Solar Nano-grid

YouSolar sells a fully-integrated solar nano-grid that includes everything the customer needs, including advanced solar panel electronics, called a micro-converter.

YouSolar’s Proprietary Advanced Solar Panel Electronics. The YouSolar STEP™ micro-converter steps each solar panel's potential from about 35 to 400 Volts DC. This video explains the STEP micro-converter and shows its application at a vacation home in the Sierra Nevada, CA, backcountry.

The PowerBloc®'s energy management system uses solar and load forecasts to decide when and how fast to charge the batteries, which helps the nano-grid perform at its best. The forecast increases solar utilization for grid-connected systems, while for off-grid systems, it reduces the chance of power loss.

Understanding and using the PowerBloc energy management system is easy. Information and system control are always at the customer’s fingertips on YouSolar's custom tablet interface, which our customers love.

Our Customers Love DIYA™, the Intuitive PowerBloc User Interface. The DIYA interface provides all the information the customer needs and allows the customer to control the system. This video features a demonstration of the application.

Here is a summary of the key features that make the PowerBloc® work:

The Market

Delivering Power to Customers Whose Needs Are Not Met by Utilities

Based on our research, the United States has tens of thousands of upscale residences with property values in excess of USD $1M built in unincorporated areas. Most of these homes rely on their own private water well. These customers lose power due to wildfires, heavy winds, and snow. Analysis commissioned by YouSolar showed that there are over 1,500 such properties in California’s wine country alone. The PowerBloc can deliver constant and high power for an uninterrupted lifestyle and the ability to run a well pump, allowing homeowners to water down the property and put out flying embers during a wildfire.

*Engineering drawing of the functional prototype of the new stackable PowerBloc®

After devastating wildfires caused power outages in our home state of California interest in the PowerBloc surged. This development presented an immediate and large market for YouSolar's technology. But wildfires are not the only natural disasters that result in a failure of utility power systems. Widespread and persistent outages occurred during an ice storm in Texas. Tropical storms and hurricanes are the main reason for power failures in Florida.

Another set of customers are homeowners or businesses who replace gas furnaces with heat pumps or add electric vehicle charging. Power needs can quickly exceed the 100 or 200 Ampere (a) utility service that typically comes with a home. Instead of requesting and paying for a service upgrade, these customers can choose a PowerBloc to boost power to the house to 300, 400 and even 800 A. Lastly, there are customers who are building new homes or businesses and are facing high bills to run utility service to the new location. 

We have a constant stream of prospective customers. At present, 50 new customers have received or are awaiting proposals. Our early success in the market has validated our analysis, and we are clearly meeting a need.

The PowerBloc is capable of powering even the largest homes and businesses. We just sold the largest system to date at a price of $180,000. Opportunities are everywhere, and our pipeline is growing.


How We Sell and Deliver the PowerBloc® and Make Money

We have a growing pipeline even with no marketing. Builders and architects of luxury homes and their electricians are currently our prime partners for lead generation. We also have strong interest from operators of critical facilities. Our database of over 1,500 potential customers from in northern California overlaps very well with the location of our first six residential installations. 

We Design and Make the PowerBlocThe PowerBloc’s TWIN™ Bi-directional Converter steps up the battery pack’s 50 Volt potential to the 400 Volts of the direct current bus. The photo shows a TWIN during assembly.

At this time, we make the sale ourselves, but we will soon begin working with partners and give them the tools to design, size, and sell our systems. Customers will also be able to purchase the PowerBloc directly through our website.

We partner with solar installers and electricians who install the solar array and connect the PowerBloc to the house. YouSolar technicians install the PowerBloc cabinets. Customers can choose the solar panels, or YouSolar can include the solar array in the proposal.

Commissioning, start-up, and operation of the PowerBloc are automatic. We remotely monitor and troubleshoot all systems.

Monitoring of Customer Systems in the CIRRUS™ Cloud. 
YouSolar monitors all PowerBlocs with internet connections remotely.
We are able to update software "over the air", trouble shoot, and control the system remotely.

By developing most power electronics and all controls, firmware, software, and hardware in-house, we have a low-cost structure that allows us to offer a competitive solution with a 40% target margin. The average price of a PowerBloc solar nano-grid, including solar panels, for a modern U.S. single-family home is between $35k to $50k. For high-end homes, system cost is between $125k and $150k.

Our revenue stream derives from initial system sales and battery replacements every ten to fifteen years. We also offer monitoring and service contracts to generate recurring annual income.


Changing the Game

In the PowerBloc®, the power flow and communication of each module, or "bloc," are parallel and independent, allowing YouSolar to deliver the PowerBloc as a stackable, plug-and-play system. After years of research, we have developed a revolutionary stackable module, and a stackable PowerBloc is now a reality.

The Stackable PowerBloc Is Plug-and-Play. We believe It Is a Game-Changer. The photo shows Baxter Smith, Product and Support Specialist with the stackable PowerBloc®.

The stackable PowerBloc assembles in a breeze and is easy to use. It has unprecedented flexibility in system configuration and sizing. Even the order of the modules inside the stack does not matter. But when assembled, interlocking modules create a nearly impenetrable monolith. After a one-button boot-up, the power is on. 

The Stackable PowerBloc STACK™, Assembles in Minutes. Arnold Leitner, Founder and CEO, demonstrates how easy it is to assemble the stackable PowerBloc®.

The Vision

Bringing the PowerBloc® to People Everywhere

YouSolar has a big market at our doorstep in California and the rest of the United States. However, people living in emerging markets account for most of the world’s population, and in the next decades 90% of electricity demand will be coming from these countries.

Grid-tied Solar Systems with Net-Metering do not Work in Emerging Markets. One of the solar arrays at the Greenschool in Bali, donated by YouSolar, its investors, and its East Asian partners.

How are we going to generate electricity without killing the climate? Today's industry does not have a solar solution. These countries are untapped markets for solar and the crux to meeting the climate challenge.

Emerging markets have unstable grids or no utility power at all. Of course, few people in these markets need or can afford a $50k or $150k PowerBloc solar nano-grid. But our success here in the U.S. allows us to perfect and lower the cost of the technology that goes into the stackable PowerBloc.

There are few, if any, trained installers, and logistics can be challenging. That is why it is so important to have the stackable and plug-and-play PowerBloc. The stackable PowerBloc is an efficient and practical power solution for these markets. It can be shipped and installed almost everywhere. It can be installed by hand – without dollies or lift jacks – and assembly is plug-and-play. We want the PowerBloc to become the world's trusted and affordable source of clean power everywhere, in a school in Bali, on a farm in Peru, or in a suburb in India.

The PowerBloc® Gives Hope. The PowerBloc is a perfect power solution for disaster relief. The image shows a rendering of prototypes of  stackable PowerBloc® modules.

We want to start the day with the number one reason why you should invest in YouSolar:

The Sun rose today.

Every morning, the Earth’s rotation brings up the Sun over the horizon. You will and should find this normal even if you have never watched a sunrise. But take the time today to look at the Sun and realize what you are looking at. You are looking at a star. Sunlight is the radiation of the plasma of its photosphere, which is heated by fusion in the sun’s core.

The Sun is a stable and reliable fusion reactor.

Sunrise in the Atacama Desert, Chile. The Atacama has the world’s highest solar irradiance during winter in the northern hemisphere.

Using quantum mechanics, photovoltaic solar panels convert the Sun’s radiation into electric power.

Rooftop PV brings fusion power directly to your home.

Modern lithium-ion batteries store this power safely and cost-effectively.

Batteries can store energy for use later at night or the next day.

Seasons and weather are critical to the distribution and flow of thermal energy on Earth and essential for biodiversity.

Sunshine decreases with clouds and in the winter. But it does not matter.

We can make hydrogen from solar energy in places worldwide where the Sun shines consistently. We can pipe, ship, and store it easily. Only a tiny fraction of Earth’s surface is required to produce the world’s energy.

Hydrogen can provide seasonal solar energy storage.

There are many ways to store the clean energy harnessed from the Sun and to make it available when and where it is needed. Let’s not waste any opportunities to do so!

The Sun Rose Today.

Let’s Make the Most of It.

Thank You and Goodbye from YouSolar | Campaign Ends Tomorrow

As an amazing campaign is coming to an end, our founder and CEO Arnold Leitner has a heartfelt Thank You message for all of you who believe in our vision and have trusted us with your investment.

But it's not quite over yet!  If you haven't invested or would like to buy a few more shares, today and tomorrow are the last chances to do so.

Thank You Again.

Our Campaign Closes Tomorrow.


YouSolar's Cash Protected from the Collapse of Silicon Valley Bank (SVB)

YouSolar maintains bank accounts at Wells Fargo and Silicon Valley Bank (SVB).

SVB collapsed on Friday, 10 March 2023 and was taken over by the Federal Deposit Insurance Corporation (FDIC).

YouSolar's cash is protected from the bank's collapse.

The funds maintained in our SVB account were fully covered by FDIC insurance at the time of the shutdown. In addition, the federal government has announced that all deposits will be guaranteed, even beyond the standard FDIC insurance.

According to the bank's website, it is resuming normal operations as of today under the umbrella of a 'bridge bank'.

We can confirm that we have access to our SVB account via online banking and were able to submit a wire transfer today.

Please see FDIC's four press releases since Friday for further background on the events.


Over $1.2 Million Raised and Counting | Three Days Left to Invest

YouSolar raised $1,080,000 on StartEngine in 2020. This time, just three weeks after passing the million-dollar mark, we have now raised over $1,230,000 – and counting. We have already surpassed the amount of our blockbuster 2020 raise! And there are still a few days to go.

How much time is left in the campaign? Less than 3 short days. Our campaign closes on March 15, 2023. Don’t miss it. Don’t cut it close – what if your area has a power outage when you try to do your last minute investment :-)

If you want to know more about YouSolar before you decide how much to invest, please read our updates and blog. There is exciting news in there, such as our recent sales of two PowerBlocs for a total of $414,000.

But if you want to know why over 800 investors have invested in the PowerBloc, here are the key reasons from our campaign page:

  • Trillions of dollars must be invested in electric power supply to keep the lights on by 2020. Who says so? Bloomberg, which forecasts that power grids will require an estimated $28.7 trillion globally in investments to meet demand from electrified homes and electric vehicles by 2050. This is a lot of money in an epochal shift happening now. And we are already deep in it.
  • Help create energy independence. Here and everywhere. Today, YouSolar helps customers in California avoid lengthy, uncertain, and costly utility upgrades and rising energy prices and protects them from outages due to severe weather and wildfires. Tomorrow, we want to be the alternative to utilities everywhere, from Argentina to Zimbabwe. 
  • Make an impact on the world. A good one. We believe that our next-generation, plug-and-play PowerBloc® with stackable modules will be a game changer for the world. Easy deployment is critical to quickly replace fossil fuels with clean energy.

Speed of the energy transition is of the essence because in the one minute you read this update, Antarctica and Greenland have lost 800,000 tons of ice to global warming.

Invest in Independent Power.

There Are Tons of Reasons to Do So.

Invest in YouSolar.

A Vineyard Powered By the Sun | $150,000 PowerBloc Sold

Over the past months we have established the PowerBloc as the premier independent power solution in the high-end residential market. We power amazing homes with clean and reliable energy from the sun.

While we expect luxury homes to be a lucrative and growing market for many years, we see even bigger potential in the small commercial space. This is because the PowerBloc not only has the energy and power for businesses. YouSolar also offers analytics, performance, and maintenance services that make owning a PowerBloc worry-free.

We are, therefore, excited that our most recent PowerBloc sale is to a Napa Valley vineyard. This sale not only adds to our order book but also serves as a showpiece while we are in discussions for a sale of hundreds of PowerBlocs to a retail chain.

California’s Napa Valley is one of the world’s most famous wine regions.

The Napa Valley PowerBloc will power a newly built caretaker house and a new barn for storing agricultural equipment, including an electric tractor – a sign that even agriculture is going all-electric! The PowerBloc will also prove that it can do hard work by powering four well pumps. 

The PowerBloc’s 110 kWh of energy storage in combination with a 37 kW solar array will provide resilience and almost complete independence from the utility grid to the caretaker house and barn. The PowerBloc will act as the primary power supply to these buildings, not just as the backup.

YouSolar Has Tapped the Commercial Market.

We Are Ready to Roll.

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.

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.

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.

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.

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.
