1. Structure of Polycrystalline Silicon Solar Modules 72Cell-290W Description
Solar panel refers either to a photovoltaics (PV) module, a solar hot water panel, or to a set of solar photovoltaics modules electrically
connected and mounted on a supporting structure. A PV module is a packaged, connected assembly of solar cells. Solar panels can be
used as a component of a larger photovoltaic system to generate and supply electricity in commercial and residential applications.

- Q: How can I determine the size of solar panel system I need?
- To determine the size of the solar panel system you need, you should consider factors such as your energy consumption, available roof space, and geographical location. Start by analyzing your average monthly electricity usage to estimate the amount of energy your solar panels should produce. Next, assess your roof's orientation, tilt, and shading to make sure it can accommodate the necessary number of panels. Lastly, consider your location's sunlight hours and climate conditions, as they affect the efficiency and output of solar panels. Consulting with a professional solar installer can also help you accurately determine the size of the solar panel system you need.
- Q: Do solar panels produce noise?
- No, solar panels do not produce noise as they generate electricity without any moving parts.
- Q: I need to build a battery array to use with my solar panels I just bought. I want to be able to store enough energy to be draw from it at night, possibly around the clock. Is there a down side to using the deep cycle battery I bought from autozone and 6 or 7 more just like it, or do I need to get some other battery?
- There are batteries particularly made for solar, such as the Trojan T05-RE . I think the RE stands for renewable energy. A deep cycle battery should work all right, although not quite as well. What you want to do is try out your setup first, with just one battery, and the panels provided. If this is one of those 45 watt kits, you may be surprised at how little energy you actually get from the panels. Increasing the number of batteries won't help, either - that's like getting a larger water tank, when you only have a trickle to fill it. If your goal is really to save money, the most cost-effective solar is the grid-tied type, with no batteries at all. That's what we have, and I've never regretted it.
- Q: Can solar panels be used in cloudy regions?
- Yes, solar panels can still be used in cloudy regions. While solar panels do work best under direct sunlight, they can still generate electricity from diffused or scattered sunlight present in cloudy conditions. However, the overall energy output may be lower compared to sunny regions.
- Q: (For a project)I know they are made of silicon, but I want to EVERYTHING they are made of. Ex Metal (What kind)Please tell me everything used from their production to the finished projectThank you
- Solar panels are slabs of semi-conductor metal. Technically speaking, they are a slab of silicon semi-conductor doped or added with impurities to make it a better conductor. Solar panels could also be made of Gallium Arsenide which is a semi-conductor metal exclusively used in photo-voltaic cells.The silicon slabs are polished and glossed before doping. After processing, for protection, a thin glass layer is embossed on the solar cells slab. Silicon also is shiny and reflects about 35% of sunlight. Hence, an anti-reflective coating is usually applied over the slabs to reduce the amount of sunlight lost.
- Q: Do solar panels require direct sunlight to generate electricity?
- Yes, solar panels do require direct sunlight to generate electricity. While they can still produce some electricity in indirect or diffused sunlight, their efficiency significantly decreases without direct sunlight. Direct sunlight provides the optimal conditions for solar panels to convert sunlight into electricity effectively.
- Q: There are places in the US where it is sunny almost all the time, like the southwest. But if we covered an area of the Sahara with solar panels, the sun exposure with the area would generate enough energy for the whole US at least. Plus, I would imagine it would be a great source of income for those countries.Why isn't this a topic under discussion or even mentioned between countries' governments/in Congress/in politicians' viewpoints?
- It's expensive - solar power isn't competitive with power from the grid in most countries and it's a very expensive in terms of capital - you have to put most of the money up front. Meanwhile fossil fuel plants are cheaper to build and from then on you only spend money on fuel when you're selling power (and of course you don't have to pay for the damage you cause society with air pollution and greenhouse gases).
- Q: This is for my science project and i cannot figure it outWe assumed that blue light shining on a solar panel would give off the higher volt reading because it has the shortest wavelength and the highest energy, but it was actually the lowest. Why does this happen? Im very confused And cant find the answer anywhere.... ，thank you!!
- Surely the highest volt reading will result from the wave with the largest amplitude, wavelength irrespective? You'd need to know the amplitude of the wave AFTER leaving the colour filter, since different chemicals and pigments in the filter would naturally affect the resulting wave in different ways.
- Q: im trying to run my house with with solar panels, is it possible? if so please let me know how....i have a 6000 w inverter
- No, okorder /
- Q: Are the solar panels on the roof just a gimik to get all the tree huggers to buy it, or are they actually a good, efficent design?
- treehuggers already want priuses. the solar panel is meant to run an electric ac system that cool's the prius if the car gets too hot inside. its nice, but personaly, i'd rather have it charge the battery.
