We were there!

The past 4 months have been very busy for Rtone in terms of International fairs which are always a fantastic opportunity to meet new clients and exchange views on the PV industry.

Ecobuild in March was the occasion to meet our British clients and to get first hand news on the British market. We also announced the opening of our London Office where Lucile is our Sales Manager for the UK.

The Ontario FIT Forum in April was a very interesting conference and enabled us to get acquainted with the Canadian market. Our Technical Director also gave a very interesting interview on the local radio about green energies in Ontario:

SolarExpo held in Verona was for us a key event to reinforce our position on the Italian market. With our brand new product, Rbee Solar Smart, our Italian customers have found THE tool they needed for the Scambio sul Posto.

Then came Intersolar in Munich. As always, our Northern European clients were keen to learn more about our PV monitoring solution. Approximately 66,000 visitors and 1,909 exhibitors were represented at the world’s largest exhibition for the solar industry! Intersolar is really the event which is not to be missed.

Now it is time for Eric, Sales Director and Adrien, Technical director to settle down for a while before the fair madness starts again in September!

Breaking news : DECC just published the new solar FIT for UK

The government’s response to consultation on Feed-In-Tariff has been published today by the Department of Energy and Climate Change (DECC). From 1st August, the new rate of 16p will be implemented for installations under 4 KW.

This FIT decrease comes along with some other measures such as an increase of the export tariff to 4.5p/Kwh. The tariff will also be guaranteed for 20 years instead of 25. The government official response can be found on the DECC website. And the new Feed-In-Tariff rate table can be accessed here.

Remotely monitoring installations and having a clear understanding of the return on investment is becoming a crucial part of producers buying process. Rbee Solar can be the “all in one place” monitoring solution your producers are looking for.

Why an accurate monitoring is becoming more important as the FIT decreases

Rbee Solar PV monitoring

This is no big news, the British government is currently in the process of reducing the Feed-In-Tariff for solar.

After a bit of “quarrel” about dates, the Feed-In-Tariff initially decreased from 43.3p to 21p on the 3rd March 2012. A new change was originally planned for the 1st July, but the DECC is currently considering moving the deadline by up to one month.

However, decrease in the FIT is a reality and grid-parity will at some point becomes one. So, what is the direct impact for producers? Solar photovoltaic will remain a good investment as energy bills tend to be more and more expensive. But reduced subsidies will also mean that monitoring their system, and making sure it is producing as much as it can, is going to become a crucial issue for producers to ensure a reasonable return on investment.

Producers therefore need to access their production data in a timely and convenient manner. A web application, that can be accessed both from a computer and a smartphone remains one of the easiest way to do it.  However, production data are not enough for producers to understand whether their panels are doing good or poorly. An understanding of the potential performance, i.e. of the installation irradiation, is crucial.
However, using physical irradiance sensor is often quite costly for residential producers. A good alternative are radiation data collected through satellite, a cost effective and reliable way to compare potential and actual production.

Rbee Solar can provide residential producers with a trusty solution to follow their actual production, and what they could be expecting. Offering producers to control their installation will for sure be a value added as the FIT is decreasing and return on investment becomes a crucial issue.

Greek sun shines through the crisis

Although Greece is going through an important economic and social crisis, due to the importance of becoming self-sufficient in terms of energy production and consumption renewable energies have continued to do well. Rtone believes strongly in the future of the renewables sector in Greece and to service the solar sector’s needs for monitoring opened an office in Athens in April 2012. I work full-time as the office’s permanent representative in Greece.

In particular from an investment perspective the solar sector has become increasingly interesting. Greece is very favorable to this sector due to 1) having the highest number of sunshine hours in Europe and 2) very high government subsidies for solar production.

Since Greece started investing in photovoltaics, the take-up rate has been very fast. According to Bloomberg, the Greek Government approved 393mWp in 2009, which increased to 1793kW by 2010.

The following graph, taken from the Hellenic Association of Photovoltaic Companies (, shows strong increases in the number of installations for all sizes of photovolataic installations. It is particularly of note the emergence of the domestic sector as an important production source with the Greek government receiving 30000 applications for small projects totalling 5182mWp in 2011 (Bloomberg).

Small projects have been boosted by simplified procedures such as the elimination of both production licenses for projects of less than 1 megawatt and environmental permits for rooftop plants. Furthermore domestic installations up to 10kWp enjoy the highest subsidies offered by the Greek government for solar production which are currently at €0,525 per KWh.

An installation which produces just under 10kWp costs between €20,000 and €35000 and on average has fallen by €3000 since a year ago due to the fall in panel prices. A smaller installation which would take up 50-70 square metres and would produce between 3,5-5kWp costs around the €12000 mark. The growing number of solar installers is leading companied to having to differentiate themselves from their competitors by by better service. One of the ways which they can do this is through the Rbee Solar monitoring service. Rbee Solar guarantees that any issues that may arise after-sale will be promptly dealt with offering the client peace of mind about the income from his solar installation.

Rtone’s own network and research confirms that the future for the PV sector looks sunny. The only challenge at the moment for domestic installations is concerns about the financial health of the Public Power Corporation (PPC). However these ought not to be too great as the PPC can always increase the price of the electricity it sells to compensate for any cash flow problems.
