From 2008-2011, Centre of Design RMIT produced numerous life cycle thinking resources for schools working with CERES Education as part of the ResourceSmart AuSSI Vic framework.
The advent of solar power technology has lead to all sorts of new gadgets and tools that run on the clean, renewable energy from the sun. Heating a pool can dramatically increase household energy bills, although an unheated pool may be all but unusable in cooler climates.
Of course, not all solar energy products are simply accessories to a home; solar panels and generators can replace a traditional electricity system and provide enough power to run an entire house.
Many experts consider current solar energy products to be just the tip of the iceberg as far as the potential applications for solar power. You will be contacted by up to three, independent, trusted solar system suppliers shortly (usually within 48 hours).
Last updated May 7, 2014 by Mathias Aarre Maehlum Solar panel manufacturers put a lot of effort into making their solar panels robust.
The majority of manufacturers offer the 25-year standard solar panel warranty, which means that power output should not be less than 80% of rated power after 25 years.
The truth is we don`t really know – there`s not really a lot of data to look at since photovoltaics is a relatively new technology (the vast majority of all solar panels are less than 10 years old).
The technology has improved, the solar panels on today`s market are more robust and durable. I would bet that a solar panel installed today would be up and running (and still generating a good amount of electricity) 30 – 40 years down the line. The more weather and wind the solar panels are exposed to, the faster they will degrade (e.g.

What’s not added to the cost is that the asphalt shingles below may not survive as long as the solar panel. Would make sense to me they should last indefinitely if you kept them out of the sun except for when you needed them. Purchase is not required and your details will not be stored or used for any other marketing purposes. Energy Informative's mission is to educate and empower homeowners about solar panels and energy efficiency.

Setting up a webcam sight illuminator over your laptop's webcam will certainly “enlighten” your online conversations. There are a number of means available to increase solar panel output and efficiency — some of which may be utilized by the serious experimenter. Unfortunately, we live in the real world and the highest efficiency technologies are either unaffordable or have not been put into production. Note that micro-cracks effectively reduce the fill factor so that it takes a larger surface area (more cracked cells) to obtain the same power output. For long life, solar cells must be protected from the elements (rain, snow, hail, bird dropping etc).
The optimum tilt angle changes slowly as the earth rotates on its axis, therefore it is not generally required to track this change automatically. Solar panel output power may be increased via a light concentrator such as a Fresnel lens or mirror.


Since the solar panel does not put out the correct voltage to charge a battery, it must be controlled via a solar charge controller to prevent battery overcharge. I read somewhere else that they(DSM) are testing now with another product together with the public (for free) to increase the output by 5% also with a coating. Not much you can do for a moving vehicle because orienting it toward the sun creates unreasonable air resistance.
The only thing that I can think of is to add more surface area by mounting more cells on the hood and trunk surfaces –flexible panels are also available for such. This requires two solar panels–one oriented toward the morning sun and the other toward the afternoon sun. I will try out above trick but i am interested to increase the efficiency of solar panel which is installed on over the pond (i.e above water surface) .
Not exactly –total energy harvesting may be reduced, but useful output current period is increased by up to 3hours (guess). This is not optimum for getting max charge into batteries, but is optimum for operating solar powered equipment (perhaps without batteries) during daylight hours. If there are no photons striking the panels, the electrons remain in place and no electricity is generated.
The main reason standard solar panels cannot charge in the moonlight is the nature of the moon's light. This is not to say that the power of the stars could not be used to generate electricity on Earth. There are reports about a proprietary material developed by Russian scientists that can convert stellar energy into electricity 24 hours a day. The difference between the radiation from the sun and the moon in the tropics is over 170,000 times.
This is a brilliant analysis on the difference between moonlight and sunlight – the former is reflected and the latter is direct. Although many solar energy products are novelty products, the energy source is quickly growing in popularity as more people turn to renewable energy sources. To keep utility bills down while keeping the pool at tropical temperatures, consider solar powered pool heating discs. Radios that run on solar power can allow people to keep up with current news and announcements in case of power outages or natural disasters.
Typically installed on a roof, solar panels provide homes and businesses with clean, renewable energy that results in far less expensive utility bills. In addition to making the solar powered sun visor radio possible, solar energy technology may soon allow whole cities to run on clean, inexpensive energy from the sun.
For what its worth I shall place one in the sun and measure its output and report my findings according.Hope that adds to the conversation.
I was wondering how to enhance the power of a solar panel on top of a small solar powered car. I have a roof-top installation has 25 panels facing West and 19 facing East (as the gable roof is E-W only). A material sensitive to stellar energy, visible or invisible, could be used to create "stellar panels," which could supplement solar cells by generating electricity at night or on cloudy days.
This "heteroelectric" material is said to be less expensive to produce than standard solar cells, and has an efficiency rating of 90%, compared to the 10-12% efficiency rating of silicon-based solar panels currently in use. We know ours are a good quality and like the ones used in Scandinavia, they operate during lower light levels than many solar panels but we were surprised the other night we had a really bright strong moonlight and noticed the Solar Power meter was whizzing around collecting KW hrs at 11 pm.


You can find kits as cheap as a few hundred dollars if you’re handy with tools and can follow the instructions easily. From outdoor lamps to solar powered visors, the world of solar energy items seems to grow each day. The discs float on the surface of the pool, absorbing energy from the sun and transferring it to the water. Solar powered battery charges can also help keep essential electronics running if power is unavailable. For people with solar panels producing more energy than necessary, check with local authorities about selling excess power to the power companies.
The lifespan of a modern solar panel is far longer than the 20 years that we use to calculate costs and earnings. While the sum total of the two panels at any given time is reduced, the period of useful output current will be much extended.
The current limitations of such an alternative energy source are financial and technological in nature. So even though most solar panels in use today are not able to use moon light or stellar energy for electricity, this does not mean that it will not become a reality in the near future.
It may be a small amount, but there is still ultraviolet radiation and other forms of radiation that continue at night that when set up can also be used to create energy. However on a clear night with a full moon, we'll see the system kick on and generate 15-20 watts.I assure you, PV panels can energize from reflected moonlight. It’s not that I ever believed solar energy panels could be charged at night, I just wasn’t sure exactly why. Manufacturers recommend that the discs cover at least one third of the water's surface for best results. Flashlights and lanterns are great for emergency kits, but can also be good choices for hikers and backpackers trying to avoid the extra weight of batteries.
Not only do solar powered products for the outdoors cut down on energy costs, they also reduce pollution by eliminating the need for light bulbs.
In the worst-case, water can seep through the surface, which can short-circuit the solar panels. A material capable of converting stellar energy into electricity has yet to be perfected, and the initial cost of building a usable array would be prohibitive.
You should install them on your roof or in your backyard facing south to capture the light from the sun. PV panels can reach operating voltage on a cloudy day, however, less current is produced relative to direct irradiance from the sun.
The excess electricity is stored in large batteries and can provide power during overnight hours. The difference is quantitative, not qualitative -- the PV modules will respond to any form of light, it's just that direct sunlight is a much richer source of photons. Frogs Leap Winery in California claims that their 135 kw PV array produces five to six kw in the light of a full moon.
