Early Stage Startup





Tagline

High end - high efficiency - low cost - PV inverter system



Elevator Pitch

The short PV version.

Optistring is developing a module level inverter system, that brings MPPT and safety shut-off funtionality to the PV modules, have 99% efficiency and can compete on price with the traditional string inverters (that is between 1/2 and 1/4 of the cost of competing technologies like power optimizers and micro inverters)

The somewhat longer version

Problem

Photovoltaic inverter systems of today suffers from either low utilization of the precious solar panels or a price tag that is to high. Legislation and safety regulations are also catching up as more and more systems are installed on buildings.

Solution

The Optistring inverter system addresses all these issues, with a low cost and high efficiency solution that are compliant with future safety regulations. To further save cost, the system integrates very well onto the backside of the solar panels.

Technology

PV inverters convert and adapt the DC from the panels into AC för the power grid. The Optistring solution harvest up to 25% more energy than traditional systems, have a breathtaking 99% efficiency, and can be produced to very competitive cost levels.

Market Opportunity

The market is huge and growing. The 2012 market value for the manufacturers of PV inverters was above 6 billion Euros, a number that is expected to double in 4-5 years. 140 million solar panels were sold last year, and about 20% of those would have made good use of being equipped with Optistring inverters.

Business model

The business model is simple. Optistring own the product, the technology and the IP. Optistring will sell the products as an OEM to large PV players, and the manufacturing is outsourced.

Company description

The company was founded in 2011 and is based on a spin-off idea from research at the Swedish Royal Institute of Technology, where we also have our office. The company is founded by a highly skilled team with experienced in technology development and start-up environments. We combine knowledge and experience from the international PV industry with technical excellence from the electronics industry as well as from power electronics research. We are today 7 employees in the company and have 2 senior advisors hooked up, with background in marketing and sales of PV electronics and purchasing of subcontracted electronics manufacturing. The two angel investors, both with an executive background from both large corp. and other successful start-ups are taking an active role in the board.

Product

This is one of our pilot installations, it's on a roof-top in the center of Stockholm next to our office. The purple boxes are our module level inverter boxes.



Why we are ecofriendly

The high efficiency and higher module utilization makes the complete system more environmentally sustainable as the manufacturing of modules is heavy on both energy and natural resources, and our system help utilizing those more.
But the Optistring system is not only very energy and module efficient; the groundbreaking technology also utilizes very little electronic hardware compared to other systems. This is the main reason for the low production costs but it also means that the energy payback time of an Optistring system is less than that of competing systems. The negative environmental impacts of producing an inverter (CO2 emissions, waste, etc.) are also reduced. The Optistring system can thus be considered, and marketed as, a truly environmentally friendly product.
On top of all this we can by the lowered system cost help in spreading the PV technology to more markets, and make clean electricity from the sun a choice for more people.
