DC voltage installations can be more cost effective in the home and office. We design [[www.leddaylighting.com leddaylighting systems]], combining LED and PV panels augmented with AC power. This maximizes the use of PV and pays of in a few years.

Photovoltaics, or PV for short, is a technology that converts light directly into electricity. Photovoltaics is also the field of study relating to this technology and there are many research institutes devoted to work on photovoltaics.[1][2] Due to the growing need for solar energy, the manufacture of solar cells and solar photovoltaic array has expanded dramatically in recent years.[3][4][5] Photovoltaic production has been doubling every two years, increasing by an average of 48 percent each year since 2002, making it the world’s fastest-growing energy technology. At the end of 2007, according to preliminary data, cumulative global production was 12,400 megawatts.[6] Roughly 90% of this generating capacity consists of grid-tied electrical systems. Such installations may be ground-mounted (and sometimes integrated with farming and grazing)[7] or built into the roof or walls of a building, known as Building Integrated Photovoltaic or BIPV for short.[8] Financial incentives, such as preferential feed-in tariffs for solar-generated electricity and net metering, have supported solar PV installations in many countries including Germany, Japan, and the United States.[9]
