Solar Energy Risks To Health

Solar electricity is a potential source of free water and electricity heating. It offers the power to enjoy electric power in remote areas of the planet. It appears to supply H&S with power, but does it?

Solar energy health risks are infrequently discussed. That could be partly because of the limited use of this source of power. It might also be down to the absence of research in this area. Some have started to study solar electricity health risks and if one researches long enough, one or two guesses are available.

Thermal Solar Energy Health Risks

Solar energy health risks are inherent to the design and installation of most thermal energy systems. These are the systems designed to heat water and air for household use.

Solar water heaters complete three basic operations before delivering hot water to your faucet or your heating unit:

1. Collect daylight and change it into heat energy.
2. Circulate liquids that transfer the heat energy to a storage unit
3. Store the hot water till you need it

The solar electricity health risks with such a system generally happen in the storage units. Some units make allowance for the growth of allergenic molds and fungi.

If proper materials are used for the storage unit, however, these solar energy systems present few, if any, health risks. Their advantages are that they are far safer than most fossil fuels or nuclear power – they have no emissions and do not pollute the air.

PV Panel solar power Health Risks

The solar electricity health risks related to photovoltaic ( PV ) panels happens before the panels are put into use on the customer’s home. PV panels are the panels used to gather solar electricity from daylight and change it into serviceable electricity.

The make of PV panels needs the employment of damaging materials. Silicon dioxide is mined from sand or quartzite and reduced with heat to pure silicon. Materials released during refining are the main health risks . Many steps in forming the photovoltaic cells employ dangerous materials. These are sprayed on the cells, and can instantaneously be breathed.

It is ascertained that solar electricity health hazards related to producing PV panels per unit energy might be between eleven and twenty-one deaths per quadrillion joules of energy produced.

Solar energy health risks from PV panels are very slight once the panels are produced and installed on the consumer’s home. This type of solar energy is known for reliability and low maintenance. The home owner seldom needs to be involved in any repairs, and thereby cuts solar energy health risks.

Passive Solar Energy Health Risks

Passive solar energy provides safety and health. A new building that maximizes this technology can reduce energy costs by nearly one half. How?

1. Warming indoor air in a place thru vertical, slanted windows facing the sun. The windows capture maximum solar power from the sunlight.
2. Picking up solar electricity in adobe or stone walls and floors, and then releasing it into the air as the temperature falls.
3. Collecting solar power in a sun space, very similar to a greenhouse built on the bright side of the home. This heat is sent into the home with correct ventilation.
4. Holding water in black roof tanks till required, cutting the working time of the home’s hot water heater.
5. Using clerestories rows of windows near roof tops that catch daylight and bounce it thru the building. The daylight decreases the requirement for electrical lights.

In Summary

Solar energy technologies present few, if any, health hazards for the consumer. Their use can reduce the possible risks to health presented by other sources of energy, providing cleaner, safer, cheaper energy.
