Top 3 solar PV safety hazards and how to avoid them1. Shock or electrocution from energized conductors Just as with other electric power generation, PV systems present the risk of shock and electrocution when current takes an unintended path through a human body.
Included hazards for firefighters in fire operations and comments are shown in Table 2.7. Flammable toxic gases may be released from fire where PV is present. Wear protective masks regardless of ventilation conditions in building. Turn off ventilation systems. Rooftop PV systems may fall inward after the roof under the systems is damaged.
UL studies have indicated that a solar PV system can generate enough DC electricity to present an electrical shock hazard. This has led to changes in firefighter safety procedures related to solar PV during periods of darkness at a working fire or an emergency scene.
Solar PV systems can present a danger due to having two electrical power sources for one building: the traditional AC electrical service provided by the PG&E power grid and the secondary electrical power source from the solar PV system.
This hazard grows if the support beams are weakened during a fire. The modules could also fall during the fire, endangering both inhabitants and first responders. Be careful during the designing process and consult with the structural engineer if necessary. Always inform firefighters of the presence of a PV system on the roof. 4.
Properly installed and undamaged PV arrays are not hazardous. The relative simplicity of PV systems makes hazards easier to predict and avoid. New technologies need to be demonstrated to be effective under the conditions in which the PV system is improperly installed or damaged.
Such hazards for firefighters caused by a rooftop PV system include: electrical shock, slips and falls, electrical arcing roof collapse, and fire risks from the PV materials. To protect firefighters and mitigate hazards, research and analyses are available to provide information on how to deal with PV components during and after firefighting.

This reliance underscores the need for a robust infrastructure, including efficient transmission networks and distribution systems, to leverage the country's renewable resources fully.
Policy In November 2014 Paraguay launched a process to design the National Energy Policy. The process, which is expected to last until November 2015, will define Paraguay's energy mix in the short, medium and long-term (25 years) and considers electricity, oil, gas and “all alternative energies”.
The heating and cooling sector in Paraguay, including at the domestic, commercial and industrial10 levels, is dominated by biomass, mostly firewood, wood chips and charcoal.11 Despite biomass accounting for about half of primary energy consumption in Paraguay12, development has happened mostly on a commercial and least-cost-option basis.
Permitting and regulation of energy projects is handled by the Viceministry of Mines and Energy. ANDE (Administración Nacional de Electricidad) is the state-owned entity responsible for satisfying Paraguay's electrical needs through generation, transmission, and distribution. Paraguay does not have a national oil company.
Electricity generation in Paraguay is dominated by the large binational hydropower projects of Itaipu (Brazil-Paraguay, 7000MW1 for Paraguay) and Yacyreta (Argentina-Paraguay, 1600MW for Paraguay), which provide over 99% of the country's electricity and generate a large electric surplus for export.
Biomass, specifically firewood, is the largest fuel source consumed in Paraguay at 43% of final energy demand. Only 17% of fuel wood demand is met by wood from managed forests. The country continues to remove forest at one of the highest rates in all of South America at around 325,000 hectares per year, mostly in the Western Chaco region.
