Customer-owned renewable energy projects

We provided support for nearly 100 renewable energy projects in recent years. The links below go to summaries of some of the projects and/or real-time production data from the solar photovoltaic and wind renewable energy generation systems.

Questions and answers

What is solar or photovoltaic (PV) electricity?

Solar cells, also called photovoltaic (PV) cells, convert sunlight directly into electricity. PV gets its name from the process of converting light (photons) to electricity (voltage).

What are PV system components?

A PV system is made up of modules (groups of PV cells) – called PV panels, an inverter for a utility grid-connected system, wiring and mounting hardware.

How long do PV systems last?

A properly designed, installed and maintained PV system operates for more than 20 years. The basic PV module (interconnected, enclosed panel of PV cells) has no moving parts and can last more than 30 years.

How much electricity does a PV system generate?

A typical PV system rated at 2 kilowatts produces around 2,450 kilowatt-hours a year in Wisconsin.
