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.
