• We wanted to be able to monitor our solar systems production of power from our computers.
• We wanted to be able to monitor each panel individually to make sure each panel was operating correctly.
• We wanted an inverter system where shade on one panel would not bring down our entire system’s production as it does with a string inverter system.
• And we wanted an inverter system with the highest efficiency available that would produce the most power for us.

We found all this and more in the inverter systems we use.

SolarEdge Technologies provides solar power optimization and PV monitoring solutions, allowing maximum energy production from your solar system for a faster Return on Your Solar Investment. The SolarEdge power optimizers perform MPPT per individual module while monitoring the performance of each module. The high efficiency SolarEdge inverter is tailor-made to work with their power optimizers. The SolarEdge system provides optimal power, flexible design and full roof utilization. Module-level electronics enable enhanced maintenance and increased system safety with their SafeDC™ mechanism. 

Solaredge power optimizers will extract maximum performance from every module in your solar system. A highly-optimized algorithm ensures that each module is constantly kept at maximum power point (MPP), preventing energy losses due to module mismatch or partial shading conditions. In addition to the energy benefit, module-level MPPT is faster than MPPT performed by a centralized inverter. This allows the modules to better react to changes in sun irradiance and temperature and minimizing power loss on cloudy days when changes in irradiance are frequent and fast. This technological advantage leads to increased energy yield. The higher the energy yield the more savings you will have.

They outperform and provide better shade mitigation than String Inverters and Microinverter Systems including an Enphase based microinverter system, and also produce more power in shaded conditions. Plus, the DC-DC conversation employed by each power optimizer is highly efficient with the highest known peak efficiency in the industry of 99.5%.

When there is partial shading of a system or shading of an individual solar module SolarEdge handles these situations perfectly. Even if just one panel has shade on it, a system using a string inverter will drag the performance of all solar modules in this row down to the level of the weakest module. Solaredge power optimizers prevent this loss of yield by evaluating each individual module in the PV system. This means that the loss of yield only affects the shaded module, but never the entire system. Shadows can be created by chimneys, dormer windows, trees, neighboring buildings, clouds, and bird droppings.

With Solaredge power optimizers, small areas can now also be used to generate solar power. With conventional inverters, we used to be technically limited, for example, when it came to dormer windows with space for two or three modules. Thanks to the power optimizers, every additional area that can accommodate upwards of one module can be used. For house owners who previously thought they had to leave out small and shaded areas of their roof, they can now look forward to using all of their roof space: 100 % coverage – 100 % yield. With an increase in your roof area and system output, this makes your solar system more profitable.

With Solaredge power optimizers, you can expect to see an increase of up to 20% in the yield of your solar systems compared to using a conventional string inverter. This means that your solar system will generate higher returns over its entire lifetime.

You can monitor the output of your system and every individual module at any time from anywhere in the world; from your computer, table, or smart phone. The Monitoring Portal provided free of charge by Solaredge records the yield data of all solar modules for the lifetime of the system. This allows you to immediately identify if there are any weak modules, find the cause of the fall in output, and correct it immediately.

This new inverter line from Fronius provides 35^th Street Solar with another top of the line, world class inverter solution. It has many similarities to the SolarEdge System:  it uses power optimizers directly on the panels, offers module level monitoring, but offers us some other advantages as well…

For one, the Fronius FE Inverter Line pairs up well with our Sunpreme Maxima GxB Series Double-Glass Frameless Bifacial Panels. Due to some technical and design issues the Sunpreme panels are not a good match for the SolarEdge System. But we are so impressed with what Sunpreme offers that we searched for the best optimized inverter solution for these amazing panels. And the Fronius FE Inverter Line is the solution we were searching for.

We believe the Sunpreme / Fronius FE combination will perform as well or better than our coveted Silevo / SolarEdge System. Plus, the different systems give us alternatives to design the best system for your home based on your individual needs.

A lot of companies will just use a cheaper conventional string inverter for their systems, but we have seen first hand how much more potent a Module Level Power Optimizer is at producing more power for the same system size. Up to 20% more power works for us!

We are committed to giving our customers the absolute best equipment. And we have resoundingly decided that string inverters just don’t cut it compared to the advantages and increased power production a Module Level Power Optimized System produces. We keep asking ourselves… “Why would anyone use a string inverter for their home solar system when there is a vastly superior solution available?” SolarEdge and Fronius LE are both best in class inverter solutions that produce more power for you. We would be proud to have these systems on our roofs.

35^th Street Solar can provide you with a vastly superior system for significantly less dollars while using advanced N-Type Cell solar panels combined with SolarEdge or Fronius FE State of the Art / Module Level Power Optimized Inverter Systems.
