Quick and Dirty Solar Energy Estimating Tool > ENGINEERING.com http://bit.ly/1zKaX6P

When someone considers purchasing a photovoltaic (PV) system to offset their electric bill, one of the first steps they take is to contact a vendor and pay for a site assessment. The assessor performs many steps, including an electric load evaluation, a visual property inspection, a shading analysis, and a financial assessment. This process helps to determine the size of the array, the optimal location for solar panels and “balance of system” equipment, the payback period, and the return on investment. While detailed assessments are crucial to a well-designed and cost-effective system, a ballpark estimate can determine whether it’s worth doing the complete site assessment. Engineers frequently do “back of the envelope” calculations to determine overall feasibility; if the ballpark figures look reasonable, then the detailed analysis will follow. If not, the idea is scrubbed and no time is wasted doing a thorough assessment. http://bit.ly/1zKaX6P
