ENECO Energie chooses online solar energy monitoring solution

Ecofys has finalised an agreement with the energy company ENECO Energie to monitor the utility’s photovoltaic solar energy (PV) systems with the internet-based Sundial solution. Sundial is the first product of its kind in the Netherlands and eliminates the need to purchase comparatively expensive hardware to monitor the performance of small to medium-sized PV-systems.

Monitoring the solar city Nieuwland
ENECO will use Sundial initially for its PV customer base in Amersfoort Nieuwland - one of the world’s largest residential PV projects - with the possibility of expanding service throughout the Netherlands. In addition to identifying malfunctions early and thereby optimising the amount of electricity generated, ENECO will be able to use Sundial to understand the performance of its PV systems on a national level.

Sundial
Owners of small to medium-sized PV-systems face an interesting challenge when trying to establish the performance of their systems. Until recently, monitoring solutions required a substantial investment in hardware and software. In most cases, the investment would reach a significant percentage of the actual system cost and outweigh the gains that could be realised by identifying and correcting system malfunctions. With the introduction of Sundial, owners of PV-systems can monitor the performance and operation of their PV-systems with nothing more than a simple kWh meter and Internet access.
On the Sundial site, customers can compare the performance of their system with expected energy yields calculated from hourly measured meteorological data, a unique feature in the Netherlands.
A demo version of Sundial is available for review at http://zonnewijzer.beldezon.nl/. Sundial versions are also being developed for other EU countries.
