Production description
A solar panel is a collection of solar cells. Lots of small solar cells spread over a large area can work together to provide enough power to be useful
however, problems such as shadow effects can shut down the weaker (less illuminated) parallel string (a number of series connected cells) causing substantial power loss and possible damage because of the reverse bias applied to the shadowed cells by their illuminated partners. Strings of series cells are usually handled independently and not connected in parallel, though (as of 2014) individual power boxes are often supplied for each module, and are connected in parallel. Although modules can be interconnected to create an array with the desired peak DC voltage and loading current capacity, using independent MPPTs (maximum power point trackers) is preferable. Otherwise, shunt diodes can reduce shadowing power loss in arrays with series/parallel connected cells.[citation needed]

- Q: Ok so if i wanted to put a solar panel on my house and i live where it snows, will that be a problem? If the snow covers the solar panel will that be a problem? If so then do i have to climb on my roof and clear it off or what?
- Yes, snow will reduce the amount of energy the photovoltaics recieve and convert to electricity. Because the panels usually have a very flat glass surface, and because the slope for the panels is usually fairly high, snow will often slide off. Freezing rain, esp freezing rain changing to snow can make a covering that's difficult to get off. If you don't usually get freezing rain, and if you usually have nice sun after snow storms, your panels should be clear most of the time.
- Q: Can solar panels be installed in a community or neighborhood?
- Yes, solar panels can definitely be installed in a community or neighborhood. In fact, installing solar panels at a community or neighborhood level can have several benefits. It allows for a more cost-effective approach, as the installation and maintenance expenses can be shared among multiple households. Moreover, it promotes a more sustainable and environmentally friendly energy source, reducing reliance on fossil fuels and lowering carbon emissions. Additionally, community solar projects encourage collaboration and community engagement, fostering a sense of unity and shared responsibility towards a greener future.
- Q: I want to add solar panels to my home. I was looking online and it seems there are so many different kinds! How does it hook up to the electrical grid? How much do I need for a 2000 sf home?
- This is still not a trivial project, although it is getting easier. The usual way to do this is to contact professional installers for free quotes. In the process of getting the quote, you'll learn what considerations go into sizing a solar system. They'll look at your energy usage, and also whether your house has a good, clear, south-facing roof that doesn't get shaded during the day. They'll also look at your electrical panel to see whether they can hook right up, or additional work is needed. There are rumors of companies like Akeena planning to sell panel kits in Home Depot (in areas that Akeena does not directly serve). The idea would be that a pro installer would pick up the kit there, but a highly skilled homeowner might be able to make it work. A permit will probably be required by your jurisdiction, but that's no different than applying for any other construction. And you'll have to inform your power utility in advance, which may or may not be routine, depending on how often people connect solar in your area. If you want to see how we connected our system, a link is below. I did not really save money by doing it myself. That's because pro's can get better prices on the panels, which makes up for the labor cost.
- Q: 260 watt solar panels on an rv?
- What are you going to power with your 260w solar panels? Tools? They generally use more than 260w. The panels will generate electricity. The problem is that your tools likely don't use DC. And if you're asking here, it's not likely that you have the background to hook everything up correctly. You'd need both batteries and a pretty good sized inverter.
- Q: Can solar panels increase the value of commercial properties?
- Yes, solar panels can increase the value of commercial properties. Installing solar panels not only reduces energy costs but also demonstrates a commitment to sustainability, which is increasingly appealing to businesses and consumers. Additionally, solar panels can generate income through government incentives like feed-in tariffs or by selling excess electricity back to the grid. These factors contribute to a higher property value, making it an attractive investment for potential buyers or tenants.
- Q: i need to make a solar panel model for a project in science and i would like to know how to build a easy model at home that wont cost alot
- There are different types of solar panels. Photovoltaic for electricity, and thermal for heating water, and passive for heating air. So it would help if you would say what type you are going to build. Theere are a lot of videos on you tube on how to make solar panels. use the link below.
- 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: Can solar panels be installed on the ground instead of a roof?
- Yes, solar panels can be installed on the ground instead of a roof. Ground-mounted solar panels are a popular alternative when roofs are not suitable or available for installation. Ground-mounted systems offer flexibility in terms of placement, orientation, and size, making them an excellent option for maximizing solar energy production.
- Q: but is that per day, per hour or minute?How much watts does the average AC unit use?How much does an energy efficient lightbulb use?All in all let's hypothetically say we no longer use the electric company for our energy source, How many of these panels do you estimate it would take to supply our small home?
- The watt is a measure of instantaneous output that can also be used as an hourly measure. volt at amp for hour = watt but also a 00watt bulb requires a 00watt power source, regardless of how long it is on, the 00watts is used as an instantaneous term here. Aircon starts at about 000watts and the new energy efficient bulbs are about 7-5 watts. If you have an electric cooker, that might use 3000 watts, your computer about 500 (very variabke these days though, many are now much lower than this) Your biggest concern would be storage, solar only works when the sun shines so you need a bank of batteries to charge during the day and provide power on demand, they require proper managenemt to ensure ther are charged properly and in turn, an inverter will be required to produce the AC power your appliances will need. It all represents a huge investment with a long payback time and you would still probably need to top-up with a generator during winter, or become ahmish.
- Q: My family moved into a house that came with solar power panels but they are not connected and don't really understand how to even begin.
- You need to know some electrical basics. You need to check if they are still working and determine the output voltage with the use of testers. They are just part of a system that includes other equipments as well like a controller, car batteries, inverters, diodes.
