BP Solar Clean Power Estimator
The Clean Power Estimator works out how much pollution you can prevent
and how much you can save on your energy bills by installing solar
power.
A
Performance Calculator for Grid-Connected PV Systems
PVWATTS calculates electrical energy produced by a grid-connected
photovoltaic (PV) system. Currently, PVWATTS can be used for locations
within the United States and its territories. Researchers at the
National Renewable Energy Laboratory
developed PVWATTS to permit non-experts to quickly obtain performance
estimates for grid-connected PV systems.
CCEnergy Energy Estimator spreadsheet tools. Data is available for other cites, as well, from the NREL web site National Solar Radiation Data Base, which supplies hourly solar and meteorological data from 239 locations in the United States and its territories.
Bergey Cash Flow Calculator (MS Excel)
The Bergey Residential Cash Flow and Payback Period spreadsheet lets
you calculate the payback period for a specified utility-intertied BWC
system. Bergey Windpower Co. (BWC) is a manufacturer of small wind
turbines and systems.
Bergey WindCAD Performance Calculator (MS Excel)
Use this spreadsheet to calculate the potential windpower of a Bergey
Windpower WindCAD Model turbine based upon input about your
installation environment.

CCEnergy Guidelines for making survey sketches (pdf)
CCEnergy will generate a scaled CAD drawing of the proposed array
location as a means of determining how many modules or collectors can
physically fit in a given space. These guidelines help our field
representatives to create better sketches so that our draftsman can
work quickly and efficiently.
CCEnergy Solar Electric (PV) System Installation Inspection Checklist
(pdf)
When a member installation is complete, the co-op performs an in-depth
inspection of the system to make sure that all components have been
installed properly and that the system is performing within
specifications.
