Thinking Small and Simple = Thinking Smart

Thinking Small and Simple = Thinking Smart

Over the past decade, rooftop solar has made a big impact on energy generation. Now, in California, energy can be “free” during the day when solar is abundant. That is one of the reasons you have seen CleanStart talk about storage so much. To battle, the BIG problem of Climate Change Utilities and new companies have been advancing storage solutions. One of those companies, Simpl Global, led by Farid Dibachi has developed a battery around the needs of rooftop solar consumers. 

Farid Dibachi is a habitual entrepreneur and has been innovating to make storage simple, hence Simpl Global.  Rooftop solar owners are conscious of their energy cost, and Utilities switching to Time of Use becomes a pain point.  Dibachi saw solar customers getting hit twice with the shift to Time of Use. With their solar systems generating power 3 to 5 hours a day when prices are cheap, they get less for the electricity they generate and pay more for electricity when they are not generating.

From Simpl Global Slides

Residential consumers install solar because it made sense as a capital investment providing a return.  Why batteries were not taking off as solar had is because the cost has typically been greater than the savings.  With that in mind, Dibachi formed Simpl Global with engineers and entrepreneurs to tackle these challenges. They created the SimplBox with innovative technology in Impedance matching, IoT networked controls, and plastics engineered for thermally protecting the energy storage, with a simple design for easy install under a solar panel. 

Their goal was to make a battery that was easy to install and use while being affordable.  They have created SimplBox a safer lithium iron phosphate battery with a unique battery management system. Conventional battery storage systems for home PV require a number of individual devices to manage power flows.  Farid and his team decided to make a battery that paired easily with rooftop solar and relied on clever electronics to replace many of the additional devices.  What they have created is a smart battery that efficiently accepts and delivers power simultaneously.  

Dibachi is particularly proud of the ease of installing and how their advancements in impedance matching have led to a battery management system with high efficiency that can just be plugged in.  The system works like a series of valves efficiently accepting and delivering power simultaneously.  Its efficacy and simplicity allow it to be modular, meaning expanding storage capacity is as easy as plugging-in another SimplBox and using off the shelf inverters for the systems connection to the grid.  This is big, because of its versatility, but it also allows it to be small.

SimplBox System by Simpl Global

This versatility allows for the SimplBox to scale up for use in Utility Solar. It isn’t limited by the capacity of the SimplBox, because you can add more without having to change the battery management or specialized hardware. Being able to “just add more” is an advantage for utilities and solar power companies looking to make incremental changes.  

In residential storage, LG and Tesla have developed storage options greater than 10 kwh. They make them large so they can support a larger solar system and capture the max power possible.  In Sacramento, a solar system can easily fill an LG and Tesla Battery in the summer, but the average daily generation is ~6 kwh.  That low generation with install cost batteries that size is cost-prohibitive to many, especially smaller urban systems. The SimplBox is made smaller and modular, with the idea that more solar customers can take advantage of it. 

All of this addresses the pain points of residential consumers by giving them control and reducing the cost. Simpl Global plans on selling through existing solar installers and distributors this August after they complete their UL Certification in July.

Packed Crowd Hears about Rising Stars of Solar

Packed Crowd Hears about Rising Stars of Solar

It was standing room only on December 5 at our last MeetUp of the year.  The theme centered on some new products in solar—our regional “Rising Stars”.   First was Erica Lindstrom of Sustainable Technologies with their Facet product, a clever anchoring system to put PV racks on flat roofs on commercial buildings without causing leaks. Since over 80% of the cost of rooftop solar is in the racking, labor and power electronics, Facet is cutting costs where it counts the most.  It may not be obvious, but putting PV panels on a commercial building roof is not so easy. Usually the racks are just laid on the roof and ballasted with concrete blocks to prevent them from moving, or a system must be engineered to anchor where there are beams underneath one can bolt into. Using Facet reduces this part of the installation cost by 40-50% and provides more assurance that the roof remains leakproof.  Erica Lindstrom said the Facet anchors are catching on rapidly, and being approved by more and more building departments, leading to rapid growth. Facet was a runner up in the recent regional Sustainability Innovation Awards. We have profiled them in another blog

Facet Design

Second up was Kevin Logue with Spotlight Solar.  His product is a “solar tree”. It is a mounting system for putting panels on “branches” off a central “trunk”.   The result provides shade, a placed to sit and USB outlets for charging as well as 115 V AC outlets. A typical installation provides 3.6 kW of power.  It is not as economical as a ground mount or roof top solar, but that is not the point. The idea is to make people more aware of solar PV and use it in parks and plazas.  It is as much a piece of art as a power generator. Kevin is based in Fair Oaks as the West Coast salesman for Spotlight based in North Carolina. He already has several projects underway in the area, some funded in part by SMUD.  As a part of their approach, they train local workers to install these systems. They are looking for more sites.

Then Al Rich of ACR Solar presenting his innovation the MegaMat.   Al has been in the solar business for 45+ years. He got his start in selling solar thermal systems when PV was too expensive.  Now he does both kinds of installations since PV became economic. But his real passion is for collecting the heat from the PV panel so that two products are harvested from the same area of sunshine.  His MegaMat is attached to the back of a PV panel and circulates water. The water gets hot and the panel gets cooled so that it actually puts out more electricity. Heat is the enemy of PV efficiency. On a hot summer day, the PV panel may reach 150° F.  The MegaMat could lower that temp by 40°. As a rule of thumb, PV panel output decreases by about 0.25% for every degree F above 77°F, so dropping the temp by 40°F would add 10% to the output. The MegaMat is composed of an extruded high-density polymer with a lifetime of 50 years in direct sun.  Since it installs under the PV panel, lifetime should be better. Al has the MegaMat on a test home now to confirm the concept.  

 

Al Rich shares his ACR Solar experience and MegaMat 

These were really unique presentations, and demonstrated how diverse our solar clean tech companies are in the region.  Our next MeetUp is planned for the third week in January. Keep a watch for the announcement.

Necessity Gives Rise to a New Company

Necessity Gives Rise to a New Company

In 2006, a solar developer had a problem.  It wanted to win the bid to cover the roof of the Staples Center in Los Angeles with PV panels.  But like many arenas, the roof wouldn’t bear much weight and more importantly, the owner wanted to be sure the installation wouldn’t cause any leaks.  Looking at all the conventional ways to secure PV panels to the roofs of commercial buildings, the developer could not find anything suitable. Conventional systems are designed for only flat roofs and the Staples Center roof was gently curved.  More importantly, typical systems used ballasting to hold down the racks of panels to avoid making holes in the roof. But then the racks can move or the ballast (usually concrete blocks) can deteriorate. With no other option, the developer turned to its own engineers to design a new lightweight installation system appropriate for the curved roof.  And it worked. They won the bid. They installed the panels. And after a decade, still no leaks.  

In fact, the system worked so well, they decided to make a business around it.  That was the origin of Sustainable Technologies in North Natomas and its flagship product, the patented Facet Roof Mount.  It looks like a small flying saucer with a threaded center section for a bolt to hold the PV racks. It’s so simple that PV installation times are slashed and costs reduced as well.  It is used in conjunction with various flashing and sealing methods to ensure that it is water-tight. 

  

It works so well, sales are zooming, with over 85,000 likely to be sold this year, up from 30,000 last year.  The units themselves are outsourced to China, with sales done directly or through US distributors. No significant sales have been made outside the US, but a move into European markets is on the horizon.  In our judgment, the big milestone for this company is probably getting unit sales over the 10 million mark. The 120,000+ mounts sold to date support about 10 MW of solar installations. When 1000 MW worth of mounts have been sold, the technology will be on lots of developers’ radar screens and sales should zoom.

According to Erica Lindstrom, Sales and Operations Manager, the key to getting sales is receiving approvals from the roofing manufacturers and most importantly from building standards agencies.  They have certifications from most manufacturers that the use of their system does not void warranties, and are working on getting it for the most popular roofing material—EPDM or polymerized Ethylene Propylene Diene Monomer, commonly called a “rubber roof”.  Building department approvals are a longer game. Every locality and state has its own rules. Erica says they just got approval from the LA city building department to unlock one of the biggest markets in the country. Awesome!

Big Solar Big Tilt

Big Solar Big Tilt

Ever look at giant solar carports and wonder “Wouldn’t they be more effective if they followed the sun?” “Why can’t someone make something that allows them to follow the Sun?”  Well, someone has. Scarlet Solar.

Most solar tracking systems you see are complex with chains and gears.  Complexity means more cost and more chances to break. Trackers are significantly limited by the weight of solar panels, so most available ones are not practical for large carports. The conventional wisdom is that tracking systems cost vs benefit is not as appealing as just adding more stationary panels. 

But Scarlet Solar is looking to change that with the SolarTiltPort. Scarlet Solar is a recent graduate of our CEO Crash course and is touring with their TiltPort to demonstrate it. TiltPort uses a simple technology (a jackscrew) to create a significantly better product.  We went out to their demo location near Rio Vista and it is impressive, tilting a massive solar array 30 ft in sweeping wind above us. (The wind actually cools the panels making them even more efficient.) It was impressive. The installation has been in operation for 2 years and beat  production expectations generating 2,032 kWh/kW in 2018.  

The big solar carports are an ideal opportunity for Scarlet Solar. They are usually tilted at a fixed angles depending on the location. This limits the harnessable energy available, as the panel is rarely pointed right at the sun. Scarlet Solar’s TiltPort has the ability to tilt at (+/-) 30 degree angle to the sun’s direction, facing East in the morning, West at night.  It generates  a 40% increase in electricity production for the same cost of a stationary system and can support multiple panels, making it more scalable.

The TiltPort is customizable, from hundreds of units for corporations to waterproof sheds powering farms.  Each 10-car-size, 36KW, Plug-n-Play unit is installed in hours versus weeks with traditional carports.  Scarlet Solar exhibited at the recent solar Power International show and got a warm reception from several interested customers.  Now they are looking for seed money and a production facility.  

Scarlet will be presenting at our next MeetUp on December 5 at Hacker Lab.  Be sure to come!

Blue Oak Energy Pivots Back to Its Original Role

Blue Oak Energy Pivots Back to Its Original Role

We recently had the chance to catch up with one of the pioneers in the regional clean tech cluster, Blue Oak Energy.  Blue Oak was founded in Davis in 2007 by Tobin Booth to provide some specialized and integrated engineering and project management to developers of large-scale solar installations.  It grew rapidly to about 60 employees with over $15 million in revenue. It had a cumulative portfolio of over 2400 MW in projects, including the landmark 2 MW system at Google’s headquarters. It was then acquired by nationwide turnkey solar developer Coronal Energy in stages between 2015 and 2017.  The idea behind the deal was that Blue Oak would become the captive engineering team for Coronal, and would phase out of working for unrelated third parties.

Tobin moved on to become CEO of Stokes Vannoy in Seattle, a solar energy developer for commercial and industrial customers.   Long-time Blue Oak veteran Danny Lee, a Ph. D. in Mechanical Engineering, took the helm of Blue Oak as the new subsidiary of Coronal.  

As a part of Coronal, Blue Oak became less visible locally.  It pulled back on sales and marketing, getting all the work it could handle from Coronal.  Then the world changed. With tariffs on imported solar panels and a phase-down in the Investment Tax Credit for solar beginning in 2020, fewer Coronal projects were initiated.  In December 2018, Coronal asked Lee to reignite Blue Oak’s work for third parties in order to support the talented team Blue Oak had assembled.

Blue Oak provides a fairly unique service in the industry, having comprehensive experience in dealing with projects from start to finish.  The team’s experience in project and construction management gives it lots of insight to inform the whole design and project concept stages to result in an installation completed on-time and within budget.  Blue Oak’s services are highly prized and they are getting plenty of work.

Danny now has a team of 26 working with him and is looking beyond solar to apply their skills to projects.  Business is picking up again. They have about 500 MW of projects in the pipeline. They are looking at storage projects, both as a component of solar installations and on a standalone basis.  And they are looking at applying the same skills to the development of other renewable projects. One of Blue Oak’s key assets is trust. Customers trust them to do a good job, and that trust can transfer to projects beyond solar.

Danny indicated that Blue Oak is now cash-flow positive and wants to pace its growth to what can be sustained organically.  He notes that building a cohesive team takes time and he doesn’t want to rush it. It is also about to make a move to Sacramento to a facility better-suited to its needs and closer to its employee base.  

Danny will be presenting the Blue Oak story at our next MeetUp set in Davis for April 25 at the Indigo Hammond and Playle building from 5:30 to 8:30 pm.  If you want to hear more, please register for this event.  It’s free, but donations are quite welcome to keep us going.
