The platform – which has been developed alongside solar developers, project financiers, maintenance companies and site owners – is already used by many investors for close monitoring of solar generation assets in Europe.
The new version will provide two new benchmarking metrics based on metrological irradiation data, while also allowing users to see generation as a percentage of these benchmarks and triggering alarms if performance falls below user-specified boundaries.
“With Feed-in-Tariff rates falling across many solar markets, it is more important than ever for investors to monitor and optimise the performance of distributed solar portfolios in order to protect themselves from risk,” said PassivSystems CEO, Colin Calder.
“PassivLiving Professional is already in widespread use in European solar portfolios and we expect the new benchmarking features to confirm it as a key differentiator of profitability,” he said.
The two new performance benchmark calculations are irradiance-adjusted anticipated yield (which adjusts the static yield calculation for each installation to account for the irradiation measured over hourly intervals) and theoretical yield (which uses first principles based on peak output of the panels, measured irradiation, and the angle of the sun over hourly intervals). Irradiation data for these two calculations is sourced from weather stations, to remove the need for an on-site Pyrometer.
Existing features of the product include monitoring and performance reporting with half-hourly resolution for portfolios; search and group management to allow collective analysis or drilling down to individual sites; reporting tailored to different criteria and timescales to suit business processes; tracking of key subsidy dates and provision of remote meter readings for large portfolios of installations; comprehensive alarms to minimise down-time; and a secure online portal tailored to multiple stakeholders, such as installers and financiers.
