PV system sizing for 100% self-consumption
A group of researchers has proposed a new method for the sizing of PV systems that do not rely on an anti-dump system and operate without the possibility of injecting power into the grid. The novel approach requires an estimate of the annual hourly profile and the minimum power demanded, as well as the use of an irradiance meter and an electrical network analyzer.
Solar 101: How to calculate your solar system’s payback period
The simplest way to model the payback period is to divide the project’s costs by its expected annual production number. That’s a good start, but it doesn’t tell the whole story.
