Integrated electrical and low-voltage systems of all types—inside and outside a building—encompass the range of work that electrical contractors do.

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.
