Solar panel working process
In addition to being the ultimate source of all life on earth, the sun is an infinitely renewable, completely pollution-free source of electricity. Instead of burning fossil fuels dug up from the ground in a big power plant – a very 19th century, industrial age approach, when you think about it – solar panels convert sunlight directly into electricity, with no harmful emissions.
Specification of Solar Monocrystalline Series

- Q: Hi. I need to build a solar panel for a project. it should be able to light a 60 watt light bulb. also, it should be about 3x3 ft if it is 50% efficient. if anyone knows any websites or can help me, please answer! thanks.
- Making your own photovoltaic (solar electric) panel is a nontrivial matter if you want to get 60 watts out of it. If this is a science fair project, there are some possible paths that I'd suggest: ) Make your own cupric oxide panel. With just one square foot, you can harvest perhaps 0.5 mW in bright sun - enough to power a solar calculator; -or- 2) Buy a panel to light your 60 watt bulb. You could probably get away with a panel that is 6 square feet, but would use a car headlight as the lamp. If you wanted to light a regular household bulb, you would need electronics to step up the voltage, and you would lose a sizeable fraction of the energy just in the conversion. -or- 3) Buy broken solar cell pieces, or individual solar cells, and solder them together into your own panel. This is a LOT of trouble, and is a finicky process to get working and keep working. And it may not end up being cheaper than buying a ready-made panel. But you can claim that you made it! By the way, crystalline silicon panels are in the ballpark of 5% efficient, and a 3' x 3' one would produce in the neighborhood of 20 watts.
- Q: Can solar panels be installed on camping sites?
- Yes, solar panels can be installed on camping sites. They provide a sustainable and renewable source of energy, allowing campers to power their equipment and devices while minimizing their environmental impact.
- Q: What is the biggest solar panel you can buy?How much energy can it produce in kwh?Thanks :)
- There are panels made up to about 250 watts. You string them together in series/parallel to get more power. Depending on your average insolation, a 250 watt panel caqn produce anywhere from a kwh/day to two kwh/day (averaged over the year - it's less in the winter and more in the summer and can range from 0 to three kwh/day). Powering a city also requires energy storage for nightime or cloudy days. The cost of this can exceed the cost of the panels by a factor of three. DK
- Q: Is there such a thing as portable solar panels? Can these be obtained for say a mobile homes / caravans etc.
- Yes there are lots available in many different types for instance take a look at www.okorder
- Q: How do solar panels affect the property's energy efficiency rating?
- Solar panels can significantly improve a property's energy efficiency rating by generating clean and renewable electricity. As they harness the power of the sun, solar panels reduce reliance on traditional energy sources, resulting in lower energy consumption and reduced greenhouse gas emissions. This increased energy efficiency positively impacts the property's overall energy performance and can potentially lead to improved ratings and lower utility bills.
- Q: Also, what's the solar panel's rate of producing electricity?
- Solar thermal in commercial applications is more productive than natural gas, taking in consideration the sun must be out. the reason being is when natural gas is exposed to a heating element(boiler, hot water heater) it loses efficiency. lets say solar thermal can produce a therm of hot water, but that would equal .2 therms of natural gas using an 80 percent efficient boiler. solar being close to 95 percent efficient. No boiler can do that. now when the sun goes down, fossil fuel can beat electrically stored energy, not stored steam energy in a thermal plant for example. but that all depends on efficient steam generators.
- Q: Can solar panels be used to power a greenhouse?
- Yes, solar panels can be used to power a greenhouse. Solar panels convert sunlight into electricity, which can then be used to power various electrical systems in a greenhouse, such as lighting, ventilation, heating, and irrigation. This renewable energy source offers an environmentally friendly and cost-effective solution for greenhouse operations.
- Q: Any opinion on harbor freight solar panels ?
- Actually, if you are looking to start slow and inexpensive, they are an economical way to get your feet wet, so to speak. I also tried the make them yourself kits, where you get a stack of cells, a frame and solder and you have to get the glass and assemble it yourself. I combined the Harbor Freight kit with one of those panels. Problems you will run into start with the kit having no inverter and not much information on any kind of power storage, you get to work that out for yourself. I initially wired them to provide all the power for the ceiling mounted lights in a small house, on a totally independent circuit, using 3 car batteries for storage. It worked perfectly, however the code inspector I got from the City could NOT fathom that my system had no connection whatsoever to his grid and would not pass it, even though I showed him the separate breaker box that was not supplied by the line coming into the house for the rest of the power. I finally gave up on him and put the lights back into the main system and use the solar setup to charge cell phones and occasionally power a lamp, as the inverter has plugs right on it. It keeps those car batteries fully charged going on 4 years now, with no issues detected at all.
- Q: Can solar panels be installed on a historic building?
- Yes, solar panels can be installed on a historic building with careful planning and consideration. It is important to ensure that the installation does not compromise the architectural integrity or aesthetic value of the building. Special mounting systems and design techniques can be used to minimize any visual impact. Additionally, local regulations and preservation guidelines may need to be followed.
- Q: I'm wondering if the cost of the panels and equipment have come down enough to make them viable in areas like Seattle or Vancuver for example.
- The key is the average insolation value for the location. This is a number that represents the effective numbers of sunlight available per day. The insolation for Seattle varies from 2.9 and 3.57, depending on who is reporting the number. The insolation where I live, near San Francisco is 5. For me, solar is paying off.
