As the PV market continues to mature and solar energy becomes a growing source of energy, there are efforts to make PV systems even safer than they currently are. To date, the industry has developed increasingly stricter safety standards, such as Rapid Shutdown and arc detection. SolarEdge recently announced a safety innovation that is designed to detect heat abnormalities and initiate shutdown before an arc occurs and extends safety to the connector level. Fires in PV systems are fairly...

As with many industries, sometimes providing post-sale services is just as important as pre-sales. In some industries, this is important to create repeat customers, while in others it can be more important due to the generation of business referrals and positive reviews. In the solar energy industry, in which a system’s lifetime is 25-years, post-sale service may not necessarily be a strong revenue generator for traditional installation companies, but it can be important for positive...

As commercial PV systems are becoming increasingly prevalent, the competition is increasing in terms of the system return on investment (ROI). One method to improve system ROI is to decrease the CAPEX/upfront costs of the system, and this can be done by increasing string length. Because modules and inverters are decreasing in price, balance of system (BOS) costs, which make up about 10% of commercial rooftop costs, have been identified as the next option for decreasing these CAPEX/upfront...

PV systems offer a number of benefits, from financial savings to environmental advantages and energy independence. As these benefits are driving PV systems to be installed around the world, the industry has gained a better knowledge of the needs for PV system safety. In general, PV systems are safe, reliable, and do not inherently pose danger to people or property. However, it is important to remember that as long as the sun is up, PV panels and wires are energized with high DC voltages....
