Solar Energy Risks

A solar radiation system such as rooftop solar heating is a potential alternative power source, supplying heat and electricity for homes, educational institutions, hospitals and businesses. A distinct advantage of this system is that solar radiation can offer services to remote areas of the world, improving the lifestyle for the inhabitants. Concern remains, however, about the risks associated with using the sun as an energy source. Depending on the methods used in converting the sun's energy into a usable resource for heating, cooling and providing electricity, some health and environmental risks can be involved.

Mold in Storage Unit

• A storage unit can grow unhealthy molds and allergens.

  A thermal energy system is a heating and cooling unit for household use. The thermal energy system equipment collects sunlight and converts it to heat, circulates fluid to transfer heat energy to the storage unit and then stores the water until needed. Allergenic molds and fungi can grow within the storage unit and produce an unhealthy atmosphere for those individuals inhabiting the area.

  As long as the materials used in the storage unit, however, are appropriate for the job, these solar energy systems have a low risk of endangering health. Since they have no emissions, they do not pose a pollution problem and are much safer than most fossil fuels or nuclear power.

Toxic Fumes in Manufacturing

• Toxic fumes can harm those working in manufacturing.

  A photovoltaic (PV) panel when installed on a home's roof accumulates energy from sunlight and adapts it for use as electricity in the home. Because the process requires using harmful materials, those individuals involved in manufacturing the panels can endure health problems. The process of reducing silicon dioxide to pure silicon emits poisons into the air. In addition, workers spray noxious materials onto the photovoltaic cells, inhaling fumes and breathing toxins. Once the panel installation occurs, however, there is very little physical risk to the occupants.

Land Disturbance

• Animals' grazing land is in jeopardy when solar radiation collection facilities take the space.

  Solar radiation collection facilities take up space when used to collect and generate electricity commercially. Additionally, the solar collectors can interfere with natural sunlight, drainage and rainfall. Also, the large arrays of solar collectors create opportunities for birds to perch on them, affecting both birds and prey. As more building become necessary because of energy demand, new power facilities replace animals' grazing land.

Hazardous Waste

• Improper disposal can cause environment contamination.

  Improper disposal of damaged or decommissioned PV panels can contaminate the environment. In addition, hydraulic fluids, lubricants and coolants often used in most industrial facilities can cause spillage of hazardous waste. Conscientious planning and careful maintenance can minimize the impact of potential health hazards.

Fire Hazard

• Thicker more insulated wire can withstand greater heat.

  Fire hazard can be a concern for solar home systems just as for any electrical system. Faulty wiring or damage to the components of the system can be a problem. Whether installing your own system or hiring contractors to do the installation, you need to know the basics of solar PV safety.

  The correct wire size and proper grounding are the most essential elements in the safe operation of a solar system. Thicker, more insulated wire can carry more current and withstand greater heat. Too much power and inadequate wire cause melted insulation, thus becoming a potential fire hazard.

  If your system is tied to your utility system, then grounding is not a concern since it should already be grounded. If your system is off grid, then you must install a ground for protection against lightning strikes and other dangers.
