Q&A with Fronius Solar Energy

What is the API with SREC Trade for?

Through the direct interface between Fronius Solar.web and the SREC Trade platform, homeowners with a Fronius system can benefit from SREC trade credits. https://www.srectrade.com/

What is an API?

The Solar.web Application Programming Interface (API) is an application-to-application interface for accessing data on the Solar.web server. Two applications (client requesting data and Solar.web delivering data) are interacting via API to each other without any user intervention. In this case, the SREC Trade platform is connected to the Fronius Solar.web server.

What are SRECs?

SREC stands for Solar Energy Renewable Energy Credits. It's a credit for every kWh of solar energy produced. These credits can be traded on SREC markets (similar to CO2 certificates).

What is SREC Trade?

SREC Trade is one of the largest SREC transaction and management firms in the industry, with over 519 MW of solar assets under management. The company facilitates the brokerage of spot and forward contract SREC transactions in the over-the-counter markets.  SREC Trade’s clients cover all market participants including competitive electricity suppliers, utilities, project developers, PPA providers, leasing companies, installation firms, and individual commercial and residential system owners.

How can I trade the SRECs my system generates?

Your system generates electricity, this production is reported to SREC Trade (via Solar.web), which registers the SRECs and creates them in your trade account. SREC Trade sells your SRECs at the best possible price and you are paid within 10 business days.

What does an installer or home owner need to do in Solar.web to connect the system to SREC Trade?

The solar system needs to be connected to Fronius Solar.web. The system owner or installer then has to link their SREC account to the Solar.web system within the SREC portal. Please contact SREC Trade for support, if needed - www.srectrade.com

What accuracy has the data Fronius sends to SREC Trade?

For systems below 10 kW the accuracy of the inverter is sufficient. For systems above 10 kW a third party Revenue Grade Meter (RGM) is needed. Fronius inverters can be connected to any third party meter with SunSpec Modbus interface.

Does the system owner or installer have to pay Fronius for the API?

No. Only SREC Trade will charge the homeowners with a fee for their services.  Their value is to collect power data and bundle them with other homeowners data and submit it to the utility at best price

Can I add my old Fronius system to this?

Yes, any system with a Fronius inverter can be connected to Fronius Solar.web to utilize the interface with SREC Trade. By doing so, also existing systems can benefit from trading with SREC certificates.
