Solar Power System - Income and ROI
System Income & Return on Investment calculator
This solar power system calculator allows you to estimate the income of a solar system over many years.
It also allows you to compare a high-quality system income stream versus a 2nd lower priced/less efficient system.
It enables you to work out which solar power system gives you a better return on investment over the life of your system.
Example: estimate the income from a new system, and also compare it to an existing, older solar system to see if it's worthwhile to upgrade.
