performs renewable energy and other systems
performance analyses, based on
periodic system tests and measurements or on long-term (annual) data
outputs. Written reports, technical papers, and oral
presentations with appropriate
visual aids can be generated from these analyses. TDI

Data Acquisition Systems
SWTDI designs, builds, and installs data
acquisition systems (DASs) for any size PV,
solar thermal (hot-water), electric vehicle, or wind energy
system. Measured data
can include all resource, weather, and electrical and mechanical
parameters are stored in data loggers and transmitted daily to central
(SWTDI or customer) via land-line telephone, cellular telephone, radio
satellite telemetry systems.
systems can range in size from
simple systems measuring only two or
three parameters at hourly intervals with on-site readouts to systems
of parameters with remote collection and analysis.
data networks process and display
the real-time outputs of several
different data acquisition systems at remote locations.
displays can show real-time and historic data along with other
information as desired.
