Announcement: PVwizard is testing advanced analytic service for any solar performance monitoring data
Our analytic engine can digest any performance data, live, or through machine-machine
interface via XML-API.

g 3 key Innovations --brochure
All performance monitoring providers can now deliver analytics and instant alert messages
to their clients with timely alert on underperformance. With optional features such as
Dust accumulation, excess degradation due to aging, etc. that can be setup easily with 'in-the-background,
vigilent performance watch dog service by PVwizard, you get peace of mind.
Your maintenance provider will be notified of abnormal condition, and given recommended corrective action. Your investment will be maintained at high productivity level.

3 Key Innovations from Wattminder at: PVwizard.com:
- * Hotspot
detection-Diagnostics with current sensor streaming PSoC gateway
- * Complex
Irradiance Photonmeter with 9 directional components
- * Dust-Rain model to assess
degradation & cleaning schedule
Salient features of web services :
Hotspot/Partial Shading Diagnostics
Hall-effective sensor per string of modules
- 1-chip PSoC1
instrumentation-signal pre-processing, streaming gateway
Bayesian MAP algorithm works constantly, 6-minute decision window.
- Detects moving
or fixed geometry partial shading patterns
Sample alert message: “PV array ABC,
string 2: Partial shading by fixed
irregular object, resulting in 387W (22%) power
loss in string.”
Complex Irradiance Photonmeter, ‘Tinman’ :
characterize DNI, & Diffused irradiance in 9 directional components
- Pyranometer with
factory calibration capture DNI and much of diffused energy
- 8 Directional
photodiodes captures 45° solid angle of shallow angle of reflected energy;
characterizing local interference patterns as baseline.
- Able to detect
cloud-enhancement pattern, as well as abnormal local shading condition.
Sample alert message: “Irradiance
Abnormal parrtial shading from
SW(225° quadrant), array output impact
Dust (&Rain) Tracking model:
- Characterize a
site into 8 dust zone catagories: Urban-Tree, Urban-LoV, SubURes, SubUInd,
SubUAgr, RuralFarm, & Desert
- Captivate pollen
advisory on cleaning regime
message: “Array ABC (50KW, if unwashed since Apr 10, 2012)
maybe losing 3.6KW(7.9%) of
production due to dust layer. Recommend
cleaning ASAP.” more >>
BMC 38.3KW, actual 33.1KW ..accumulated .22” of
rain since Apr. 2012.
Other work-in-progress: Building
knowledgebase with Fault Dictionary, Conditional Probability Matrix, Knowledge
discovery, datamining, crowd-sourcing, NLP for interactive Question &
Answer session with visitor to ascertain issue of any web visitor.
