Wearable Solar Tech: A Personal Way To Use Solar Power
Powering consumer electronics has become a common solar power use in todays world solar-powered chargers like Ankers Powerport can charge anything from a cell phone to a tablet or e-reader. There are even solar-powered flashlights that can be charged by being exposed to sunlight. For those curious about the top products in solar tech, check out this top 10 list of uses for solar devices:
- Freezers/mini-fridges
- Rechargeable flashlights
As the world moves away from fossil fuels and seeks renewable sources for everyday electronics, theres no doubt that solar will continue to be adopted by the masses for any product that can be exposed to sunlight. The ultimate goal: use solar products to reinvent the way we think about power usage, and reverse the expectation for how devices should be charged. And as the conversion efficiency of solar continues to improve, this trend will expand into new markets and new products.
For example, wearable solar could soon make Apple Watches and Fitbits much more appealing to consumers unlike their standard counterparts, solar-powered smartwatches dont need to be plugged in to recharge every night. The real question is, will these large technology companies be able to integrate wearable solar technology into their products before an emerging brand beats them to it?
How Exactly Is Electricity From Solar Energy Produced
Solar panels are usually made from silicon installed in a metal panel frame with a glass casing. When photons, or particles of light, hit the thin layer of silicon on the top of a solar panel, they knock electrons off the silicon atoms.
This PV charge creates an electric current , which is captured by the wiring in solar panels. This DC electricity is then converted to alternating current by an inverter. AC is the type of electrical current used when you plug appliances into normal wall sockets.
Common Residential Uses Of Solar Power In Your Homes
Solar power is an excellent source of energy in many homes around the world. Solar energy panels have gained popularity in recent years with the many benefits offered.

Is It All Right To Install A System That Is Beyond Net Zero
If you anticipate your power needs changing in the near future, it might be a good idea to oversize your solar system for your needs today. For example, if you want to get an electric vehicle, install a heat pump, or convert from a gas-powered clothes dryer, range, or water heater to an electric one, your electricity use will likely increase significantly. Therefore, adding more solar panels is a good idea if you have enough roof space.
Otherwise, whether it is logical to go beyond net zero depends on if and how your utility company compensates you for the excess solar electricity you supply to the power grid in the form of credits on your electric bills. Currently, 41 states, Washington, D.C., and Puerto Rico have net metering laws.
Usually, the utility company pays solar system owners for any excess energy they send back to the grid, especially if it’s a net metering application, says Kumar. However, there are some states where you don’t want to send any power back to the grid because it’s not incentivized.
Most power companies pay a lower rate or even nothing for electricity beyond offsetting what the home uses. For example, if your house draws 15,000 kWh of power from the grid and supplies 17,000 kWh, the first 15,000 kWh offsets your personal use. After that, you will receive either a meager price per kWh for the excess or perhaps no compensation.

How Is Electricity Produced From Sunlight
Solar cells connected together in are the main mode of producing power with sunlight. In each cell, a material that generates an electric charge when hit by sunlight, typically silicon, is sandwiched inside weatherproof layers. Electronics connect cells and panels together into arrays and route the electricity to an inverter, which changes it from DC to AC so that it is ready to use.
Solar photovoltaics now perform well in a variety of materials and forms, thanks in part to Caltech researchers. Photovoltaics may be thick and stiff or thin and pliable, single-sided or double-sided. Arrays may be raised on metal supports or configured as solar shingles and used as roofing material.
In a less-common method called concentrated solar power or solar thermal, mirrors focus sunlight on a heat-absorbing target that typically contains a fluid. The mirrors can be trough- or dish-shaped or flat, and some track the sun. The heated fluid is used to generate electricity via a heat exchanger and a steam-powered turbine. While solar panels stop producing power at sunset, some of these systems stay online longer. That is because the liquid retains heat and can also be heated by natural gas. In fact, plants also often start heating the water for the steam cycle with natural gas before sunrise so that the system is fully operational at dawn.
How Does The Photovoltaic Effect Work For Solar
For solar panels, the photovoltaic effect occurs when photons from the suns rays hit the semi conductive material in the cell of the solar module. The photons activate electrons, causing them to free themselves from the semiconductive material.
Due to the structure of a solar panel, the free electrons move in a single direction through the junction of the panel. This movement creates an electrical current that is then sent to an inverter to be harnessed by your home.

Hot Water Solar Systems
Whole-house hot water systems are the big-scale version of the same kind of solar system that can replace the water heater providing hot water to faucets. Like that system, whole-house heating systems use solar collector panels to heat water that circulates through tubing lacing through the collector panels. But rather than being stored in a relatively small tank for use in plumbing fixtures, this hot water is also circulated through piping that provides warmth to radiators or radiant flooring tubing through the entire home. These systems often serve both purposes: heating water for use at faucets, as well as providing whole-house heating.
These are big-scale systems that use quite large solar collector panels on the roof and sophisticated tanks and circulation technology. Solar hot water heating systems are more commonly used in businesses, but they are also an option for residential use.

You can also check how compatible your roof is with solar panels using free online tools. One example is . This tool is particularly useful because it uses Google Earth to analyze the size and shape of your roof, and it looks at shaded spots. The tool even analyzes local weather patterns to assess how much solar energy you would get. Its analysis shows how much you could save on your electric bill and the recommended number of solar panels you should get. The tool even helps with comparing loans, leases and other financing options.
You simply need to enter your address and Google Earth pulls up an image of your roof. You get an estimate of how many hours of usable sunlight you have per year, how many square feet are available for panels and the estimated savings of energy over the next 20 years based on local energy costs, solar costs and incentives.
Another option is the PVWatts Calculator from the National Renewable Energy Laboratory. Again, with just your address, you can get an estimate of the electricity output you could expect from a system on your roof. PVWatts gives you a more detailed estimate, breaking it down by month. It is still just an estimate and shouldnt be taken as entirely accurate.

Australia’s Solar Energy Resources And Production
The Australian continent has the highest solar radiation per square metre of any continent and consequently some of the best solar energy resource in the world. The regions with the highest solar radiation are the desert regions in the northwest and centre of the continent.
Australia’s energy resources, including solar energy resources, and the factors impacting on the development and adoption of the various energy resources to 2030 are outlined in the Australian Energy Resource Assessment.
Australia receives an average of 58 million PJ of solar radiation per year, approximately 10 000 times larger than its total energy consumption. However, Australia’s current use of solar energy is low with solar energy accounting for only about 0.1 per cent of Australia’s total primary energy consumption. The most common use of solar energy is solar thermal water heating. Solar PV systems play an important role in off-grid electricity generation in remote areas.
Geoscience Australia is contributing to this program by providing pre-competitive solar resource prospectivity data and analysis to assist the solar industry and research community. The first steps in this project were to improve the collection of solar insolation data through a collaboration project with the Bureau of Meteorology, to increase their solar monitoring ground station network, and to improve the satellite models base used in collaboration with those ground stations.
Power Your Home With Photo

Yes, solar energy can power your entire home. Although it sounds complicated and expensive, such a system is relatively simple in concept. Solar panels lined with polycrystalline silicon, which reacts to sunlight by generating a small electrical charge, are linked together on a roof or on open land facing the sun. As the sunlight is converted to electricity, the DC current generated is sent to an inverter, which converts the DC current to AC power. This AC power feeds into your main electrical service panel, where it is used to power all the devices in your homejust like utility company electricity. Through the use of transfer switches and other safety devices, your clean, renewable power source is capable of powering your home, cabin, tool shed, or any other building for that matter.
In most locations, the utility companies now will meter your home in a manner that keeps track of the energy you are generating yourself, giving you credit for that usage and even paying you back when the power grid is making use of the energy you generate. If you are entirely “off-the-grid,” you can install a large bank of batteries to store energy for use at night or on cloudy days or rig your system with a backup generator that kicks in when there is no sunlight to power your home.
