Q:. Does it really only cost $200 in contrast to $5000 or more?2. How much would it cost to build panels that would energize an entire average household? (washer, dryer, water heater, lights, fans, a/c)3. Is there a place to get the info on how to make them for free instead of paying E4E?4. Are the professional solar panels better? more efficient? 5. Will the electric company in So. Cal. really pay you?6. Do you have to be certified to do this professionally? or an electrician? If so what schools teach it?7. Would wind generators be of any use in So. Cal.? I mean don't you really need to get the fan spinning to get energy?8. Are there any extra unseen costs? (tools, energy converter, ect)9. How much is it to get an electrician to hook you to the grid?0. Is it better to hook to batteries or the grid? Pros, cons, why?: Are there any extra unseen costs? (tools, energy converter, ect). Yes. Batteries or Inter-tie, charge controllers, inspections, wiring, inverter etc. 9. How much is it to get an electrician to hook you to the grid? Call for a quote. 0. Is it better to hook to batteries or the grid? Pros, cons, why? Batteries are expensive and only last several years. Maximum power is limited by the size of the inverter. Grid-tie eliminates the need for batteries but then you have to purchase a very expensive grid-tie inverter.

Q:How do you make solar panels and do you need a lot of them to make electricity?: It's possible to put together pre-made solar cells into your own panels, but the result will be far less durable, and more costly than simply buying commercial panels. You may encounter some websites offering to sell you information on how you can power your home cheaply with homemade panels. Every one of those I've seen is a scam. Save your money. Do you need a lot of panels to make electricity? To make a system that is worth it generally takes at least a dozen panels, although I'm sure exceptions exist. Also, it generally needs a professional install to meet legal requirements, although a few skilled homeowners do manage to do their own.

Q:Do higher watt solar panels last longer, efficiency-wise? 3 installers gave me quotes with 3 different sunpower panels. The 225, 25, 20 watt panels. Whats the con and pro's of the different wattages?: There is no difference between them besides their rated output. One may physically fit on you roof better than another, or look better, although the physical difference between those sizes is minimal. Go with whichever installer you trust, and is preferably NABCEP certified, or working towards NABCEP certification. Get references. Don't believe just because someone is an electrician they know how to install solar electric, it's a whole different animal. Make sure they are trained in installing solar.

Q:Can anyone tell me how to connect a solar panel from a calculator to a motor from an RC car.: Solar Rc Car

Q:I need help?!!: They are costly, although technology is improving. To generate enough current to be useful, the panel needs to be large quite large. The sun tracks at different angles depending on the season and the solar panel would need to be repositioned to get maximum current generation because of this.

Q:. The 2v battery will only be turning a small 2v motor that will be turning very slowly yet possibly or a long time. 2. -2 hours max per day it will be running3. I want it to be fully sufficient on solar power once the energy in the battery runs out. What specifications for my panel do you think I will need. However, i have limited space so the smaller the better as long as it can do the jobP.S: I don't know much about electricity and solar power so simple answers please :): Are you concerned about your higher energy bills? What about the atmosphere, are you worried about its resources that are nonrenewable? Solar energy and how to make solar panel are the solutions for you. Let us talk about the charges of pv strength and how practical it is for YOUR budget. The first thing you should know is that the size of your house has nothing to do with the cost on how to make solar panel. So for those people fortunate sufficient to are living in a gigantic property, pv panels are not here to overwhelm you with charges. What you do need to consider into consideration are items like how much sun you get a day, in which you stay, and how very much power you use a day. After you can appear to individuals conclusions, we can commence the math. Permit us do an instance together to figure out a ballpark expense for pv panels. Take a peak at your power bill as it is now and locate how numerous KWH you used, We will say that variety you found was 800 KWH. Now we are going to divide 800 by 30 and we get a whopping 26. 7. Don’t forget that quantity. It is how very much estimated KWH you use a evening. If you locate that you are exposed to six hours of sunlight a morning you would then consider the 26. 7 and divide it by 6. You reply should be four. 45 (or 4,450 watts). If you multiply that reply times . 5 you have successfully observed out how a lot of photo voltaic panel watts you need. The installation costs then are associated to the quantity you found above. Each and every watt usually costs $7-$9. All your installation fees need to be integrated with that estimated ending price. Now that you know how very much your method will charge, you will be relieved to know that it actually pays for itself inside six many years. There are also tax exemptions for people that select to use pv vitality. It is an investment that is really worth anyone’s time and funds Hope It's Help.

Q:Do solar panels require regular maintenance?: Yes, solar panels do require regular maintenance. This includes cleaning the panels to remove dust and debris, checking for any damage or defects, and ensuring proper functioning of the system. Regular maintenance helps to maximize the efficiency and lifespan of solar panels.

Q:How do solar panels affect the local job market?: Solar panels can have a positive impact on the local job market by creating new employment opportunities. The installation, maintenance, and manufacturing of solar panels require skilled workers, thus leading to job growth in these sectors. Additionally, the shift towards renewable energy sources like solar power can stimulate the local economy through increased investments and business development.

Q:Can solar panels be used in areas with high levels of pollution from industrial emissions?: Yes, solar panels can still be used in areas with high levels of pollution from industrial emissions. While pollution can potentially reduce the efficiency of solar panels by blocking sunlight, advancements in technology and design have made solar panels more resilient. Additionally, regular maintenance and cleaning can help mitigate the impact of pollution on solar panels, ensuring they continue to generate electricity effectively.

Q:Can solar panels be used for heating a greenhouse?: Yes, solar panels can be used for heating a greenhouse. Solar panels can be used to generate electricity, which can then be used to power heating systems in a greenhouse. This can help maintain a consistent and optimal temperature for plant growth. Additionally, solar panels can also be used to heat water, which can be circulated through a greenhouse to provide warmth.
