Systems

 

 

Integrated electrical and low-voltage systems of all types—inside and outside a building—encompass the range of work that electrical contractors do. The articles in this section highlight different types of work, from security, fire and life safety, to traditional electrical power and distribution, to lighting, cabling and more.

Historically, if a problem occurs with a traditional string power inverter that links several solar panels together in series, or even simple shade, that issue can bring down an entire solar photovoltaic (PV) array.

As government tax credits and utility rebates and incentives dry up, energy-efficiency improvements have evolved beyond the low-hanging fruit of fixture replacement at low cost.

As with most clean-energy markets, activity in the energy-storage segment is directly tied to government policies.
