Product description
The Solar System[a] is the gravitationally bound system comprising the Sun and the objects that orbit it, either directly or indirectly.[b] Of those objects that orbit the Sun directly, the largest eight are the planets,[c] with the remainder being significantly smaller objects, such asdwarf planets and small Solar System bodies. Of the objects that orbit the Sun indirectly, themoons, two are larger than the smallest planet, Mercury.
The Solar System formed 4.6 billion years ago from the gravitational collapse of a giant interstellar molecular cloud. The vast majority of the system's mass is in the Sun, with most of the remaining mass contained in Jupiter. The four smaller inner planets, Mercury, Venus, Earthand Mars, are terrestrial planets, being primarily composed of rock and metal. The four outer planets are giant planets, being substantially more massive than the terrestrials.
A solar cell, or photovoltaic cell (in very early days also termed "solar battery"[1] – a denotation which nowadays has a totally different meaning, see here), is an electrical device that converts the energy of lightdirectly into electricity by the photovoltaic effect, which is a physical and chemical phenomenon.[2] It is a form of photoelectric cell, defined as a device whose electrical characteristics, such as current, voltage, or resistance, vary when exposed to light. Solar cells are the building blocks of photovoltaic modules, otherwise known as solar panels.
olar cells are described as being photovoltaic irrespective of whether the source is sunlight or an artificial light. They are used as a photodetector (for example infrared detectors), detecting light or other electromagnetic radiation near the visible range, or measuring light intensity.

- Q: Is there a free site or resource that will teach you how to do this? Hopefully step by step and tells you how to buy all the parts ect?Which is the best resource for sale earth4energy, homemadeenergy, ect? Do they actually work and also as well as those which are professionally done?They say it will cost under $200 for a panel, but how much will this panel actually produce I mean how many panels would you have to make to produce 00% of your homes energy?
- there are plenty of free sites that tell you how to install your own solar panels. Just google diy solar panels. as to how many panels you need, it depends on what all you're trying to have them run.
- Q: where to find used solar panels?
- IF used panels are available, they are probably worn out and NOT putting out the power they were designed for. (They DO wear out!) I do NOT know of any place they are sold.
- Q: Can solar panels be used in urban areas with limited space?
- Yes, solar panels can definitely be used in urban areas with limited space. There are various innovative solutions available such as rooftop solar panels, solar panels integrated into building facades, and even solar panels installed on vertical structures like lamp posts or noise barriers. These compact and versatile options allow urban areas to harness solar energy efficiently, even with limited space.
- Q: I jotted down some notes for my Technology and Architecture class and I'm trying to figure out what i meant when i said 'Treated with gases at extremely high temperatures.' I have NO idea what I was talking about :) Im trying to figure out if what I am talking about is about Silicon, Polychristaline, or a Solar Cell/Panel.
- Let me help you get an idea of what you are talking about as your notes seems a bit jumbled. Mostly when they refer to a silicon solar cell they mean that the silicon is one crystal of silicon. (very much like a diamond, but with atoms of silicon instead of carbon). A single perfect crystal of silicon can be grown that is very large at temperatures near the melting point of silicon or around 400C and then is sawed up to create electronics or solor cells. Polycrystalline :) solar cells are also made of silicon, but instead of a single crystal it is made of a jumble of small crystals that have different sizes and directions. So these types of solar cells can be made using a silicon gas (siline: SiH4) at much lower temperatures 600-700C. So these are less expensive to make, but because they are not perfect crystals a poly solar panel that is the same size as a crystalline solar panel will make less energy. I hope that helps.
- Q: Can solar panels be used in countries with limited sunlight?
- Yes, solar panels can still be used in countries with limited sunlight. While solar panels are most effective in areas with abundant sunlight, they can still generate electricity even in regions with less sunlight. Advances in solar technology and the ability to capture diffuse sunlight have made it possible for solar panels to be used in countries with limited sunlight. Additionally, the efficiency of solar panels has improved over time, allowing them to generate electricity even in low-light conditions.
- Q: If I put a 5000 watt solar panel kit on my roof in Dublin (Ireland) - how much electricity would I realistically expect to get?An educated guess at a percentage of 5000w would do.
- Do you want a time average? During the winter you will be lucky to average 800 watts daily Summer you could get 2000 watts
- Q: cheapest price for a 20 watt solar panel sold on line
- If okorder /... , cost $75 each. I haven't personally tried that product, but the company has been around for a long time, and is not a fly-by-night. If it has to last, there are dozens of places online that will sell conventional sealed panels. Expect to pay $2.00 a watt on up nowadays.
- Q: Can solar panels be used in areas with high levels of snowfall?
- Yes, solar panels can be used in areas with high levels of snowfall. However, the performance and efficiency of the panels may be affected during snowy conditions. Regular snow removal or tilted mounting angles can help maximize their effectiveness in such areas.
- Q: right now, you would need a suitable number of solar panels just to power house that can take up a lot of real estate. so my question is, is it feasible to create something that absorbs more of the suns energy like a magnet it would suck it up. the point of doing this would be so that we wouldnt need so much space so many panels just to power home for example.i hope thats coherent.
- If you're asking whether we can make more efficient solar panels, the answer is obviously yes. Solar panel efficiency has been slowly but surely increasing every year, although the theoretical limit is being approached (but has not yet quite been reached) by crystalline silicon devices.
- Q: I am looking at a need of roughly 30w/hour need per 24 hour period. I have spent several hours now looking for information online and have found plenty of info regarding the panels themselves, but information regarding the batteries backups have been slim. I understand that there is a 5-7 hour peak time to collect the energy. I am looking for information regarding the batteries themselves. How do the batteries work, what size batteries should I look for, and what is the life expectency for the batteries? Any website links would also be appreciated!
- First, you didn't say the voltage. Second, 30 W/hour per day. Third, battery backup capacity in Ah = Ampere hour. For 2 Volt DC here's the calculations : 30 w/hour means = 0.83 or rounded Ampere hour. You know peak time 5-7 hour (let say 6 hour)charging time (collect the sun energy). Ampere hour per day (24 hour), with 20 Ah Battery backup is OK. And the Solar Panel is 3 Ampere charging capacity minimal = 3 Amp x 6 hour = 8 Amp hour.
