1.5 axis PV tracking for lower LCOE & to open new applications


2


Objective & Panelists

HeliosLite’s disruptive new 1.5 axis PV tracking solution boasts higher energy output than standard 1 axis horizontal trackers and brings cost effective tracking to decentralized PV plants. The 1st round of pilot projects deployed in Europe, South Africa and the United Arab Emirates confirm the tracker’s robustness and superior energy output.

This webinar presents an introduction to this new class of PV tracking system and how this solution can be used to reduce the LCOE of solar plants and to open new market applications.

How to improve return on investment?

A. Lower investment cost of componentsB. Higher efficiency PV modulesC. Higher energy output PV tracking devicesD. Lower O&M costE. Higher value added projects (e.g. off-grid, self-

consumption, storage,…)


22


Reduce LCOE with HLPV 1.5 axis trackers

LCOE model assumptions:

Cost of fixed rack structures: 4 c$/Wp

Cost of PV modules + inverters + BOS = 63 c$/Wp

O&M costs: 15 $/kW/year for fixed plant, 15 $/kWp/year with trackers

Financial cost: 5%/year

Degradation rate: 0.2%/year

Plant lifetime: 25 years

Conclusion and next steps

HeliosLite is currently monitoring over 900 kW of tracking systems installed in 10 countries.

HeliosLite is now engaging discussions with a world class manufacturing partner in order to scale up production for delivery of MW scale projects in 2019.

HeliosLite is looking for distribution partners and project developers to commercialize at a larger scale this new disruptive 1.5 axis tracker system.

We would like to add your project to this map!
