- Q: I heard that solar energy has a lot of advantages but are there any drawbacks in using the solar panels?
- I guess the main thing is to look out for the warranty like where the warranty is claimed and the process of claim, how efficient the inverter of the system is and also make sure you are getting value for your money.
- Q: I have two solar panels that were going to be trashed at work. I want to use them to charge batteries on my RV but i noticed they put out around 20 volts in direct sunlight. So i am wondering: -isn't this way too much voltage for a 2 volt system? -do a need some sort of a regulator connected to keep them from overcharging?
- a million. confirm you get carry of the suitable form of battery that permit to can charge from the image voltaic panel. 2. confirm you utilize a gadget which I forgot the call in spite of the fact that it's going to make confident the can charge pass one way in case the sunshine pass out so won't drain the battery at the same time because it somewhat is hook up. 3. confirm you get carry of the suitable can charge from the image voltaic panel to can charge the battery. reason is easyier to swim down the river or is it basic to swim up river.

- Q: I am curious about how much of the energy that a solar panel of a given size and capacity will produce in it's lifetime, and what fraction of that energy was required to produce it in the first place?
- The attached link is to an article from the 200 Home Power magazine. In that article the energy payback was found to be between 2 and 4 years. Newer panels are more efficient primarily because the silicon wafers used today are thinner. The silicon cell embodies most of the energy required to make a solar panel. Today most solar panels will produce the amount of energy required to manufacture them in between about 9 months and 2 years depending upon the specific technology used to make it. Solar panels are expected to produce energy for between 30 and 50 years. Therefore it takes around 5% of their total energy production to produce them. Note that these figures depend upon where the panels are installed. Panels in very sunny areas may generate more than 3 times the energy of panels in a cloudier area. Edit - The energy payback meta-study that carbonates references below mention one particular study Alsema (2000), which the authors used as a baseline to come up with their 4 year payback figure. These studies DO NOT assume ideal conditions. The Alsema study assumes an annual an irradiation of 700 kWh/m2/yr. That is the United States average irradiation and does take into account cloudy weather and the like. Under idea conditions the amount of energy collected can be almost twice as much. Albuquerque New Mexico is an example. The figures I mentioned above are recent values reported by several different panel manufacturers with whom I discussed the issue at the 2006 IEEE 4th World Conference on Photovoltaic Energy Conversion held this May. The very long payback times that carbonate highlights are almost certainly wrong. The study he references concludes that paybacks range between 2 and 8 years with 4 years being the most likely. In my opinion payback times are actually a fair bit shorter based on conversations with the manufacturers.
- Q: I am trying to built a circuit that will power two USB ports (both 5V and 0.5 amps) from the output of a solar panel that produces 20V at 0.2 amps. I have a voltage regulator that runs at 5v and 0.5 amps but I can't figure out the best way to boost the current up to 0.5 amps before I incorporate the voltage regulators.
- If you want to power both USB ports at the same times, It might not be possibble. Your solar panel only supplies 2.24 Watts (20V * 0.2A) of power and you need to deliver 2.5 Watts (5V * 0.5A) to the ports. Subtracting any losses from your regulator(s), you will be WAY over your power budget. You will need more of a solar panel or less of a load.
- Q: what are solar panels?
- every time i hear the word solar panels i think those large or small flat shiny black or grey surfaces that absorb the sunlight and convert the heat and so on so forth into energy like electricity But ...i dont know how they fully work really so, i dunno.
- Q: Could you throw some long scientific words in with your answer so I can impress my teacher, I'm looking to expand my scientific vocab. Thanks
- Actually Photovoltaic cells also called solar cells in collection forms solar panel. Photovoltaic cells consist of silicon for converting solar energy into electrical energy.
- Q: i've heard environmentalists like ed begley jr use the phrase quot;peak shaving hourswhen talking about solar energy.what does that phrase mean, please?thank you to all who respond.
- Graminoids are among the most versatile life forms. They became widespread toward the end of the Cretaceous period, and fossilized dinosaur dung (coprolites) have been found containing phytoliths of a variety that include grasses that are related to modern rice and bamboo. Grasses have adapted to conditions in lush rain forests, dry deserts, cold mountains and even intertidal habitats, and are now the most widespread plant type; grass is a valuable source of food and energy for all sorts of wildlife and organics. Graminoids are the dominant vegetation in many habitats, including grassland, salt-marsh, reedswamp and steppes. They also occur as a smaller part of the vegetation in almost every other terrestrial habitat. There are some 3,500 species of graminoids. Many types of animals eat grass as their main source of food, and are called graminivores – these include cattle, sheep, horses, rabbits and many invertebrates, such as grasshoppers and the caterpillars of many brown butterflies. Grasses are also eaten by omnivorous or even occasionally by primarily carnivorous animals. In the study of ecological communities, herbaceous plants are divided into graminoids and forbs, which are herbaceous dicotyledons, mostly with broad leaves.
- Q: are there solar panel that work without the sun?
- There cannot be a solar panel which works without sun light. But solar panels can work without sunlight. For example you would have seen the battery less calculators which work on solar power. they work in the night too with enough light coming from the bulbs in the room. So the answer to your question in yes. But for generating power we have to have a source which is free and we cannot put the panel in lighted area, which will make is not economical since the nett power obtained will be negative.
- Q: Can solar panels be installed on community centers or libraries?
- Yes, solar panels can be installed on community centers or libraries. In fact, community centers and libraries are often ideal locations for solar panel installation due to their large roof spaces and potential for generating significant amounts of clean energy. Additionally, solar panels on these public buildings can serve as a visible example of renewable energy adoption and can help reduce electricity costs while promoting sustainability within the community.
