solarROI - Commercial Financial Evaluation of Solar Power Systems

Expert independent calculation of the financial return from a solar power investment Dollar-Sign-Solar-Panels What return can you expect from a solar power system? While many questionable solar salesmen will promise you a fortune, solar financial analysis depends upon many factors and only SunWiz can account for them all. We perform an hour-by-hour analysis of solar production for your roof, accounting for your hourly consumption in each moment and hourly tariff variations. Our financial analysis can incorporate the cost of equipment upkeep and complex electricity tariffs, system performance reduction, and lease/mortgage finance. We deliver to you a professional report that communicates the expected true payback, Return on Investment (ROI), Net Present Value (NPV) and Internal Rate of Return (IRR) of your solar investment. We calculate your expected bill reduction, and (crucially) provide the most accurate possible assessment of whether your solar power will be consumed on site or wasted on the grid.
