Q: Is it really possible for me living in Denver to build and install and setup my own solar panel to help make electricity for my home?
Sure you can build your own solar panels, people do it all the time, especially with the efficiency of PV technology accelerating. How much you spend on a system depends on how much work you are willing to do for yourself, and how much and how efficiently you consume power. You can go all the way from high-end prefab installs that will run about $50 grand to fill the energy needs for an average 3/2 suburban home. You can buy kits and install them yourself, that cuts your price down quite a lot. You can purchase the components and put together a system yourself really cheaply. You can save even more money if you buy stuff used. You could actually build solar photovoltaic panels yourself, but it is a serious pain in the behind, you will need to use copper sheets and some highschool chemistry and do a lot of experimenting, and even if you do it right you definitly won't be able to replicate the power output available in manufactured silicone photovoltaic cells. So I say don't even bother. To get an idea of what a PV system for your local area might put out, use the PV-WATTS calculator at the government Renewable Resource Data Center. To learn how to build home solar energy systems, there's a lot of good free information online.
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: Can solar panels be used during a power outage?
No, solar panels cannot be used during a power outage unless they are connected to a battery storage system. Without a battery backup, solar panels will also lose power when the grid goes down.
Q: Can solar panels be installed on historic homes or buildings?
Yes, solar panels can be installed on historic homes or buildings. However, it is important to consider the specific regulations and guidelines set by local historic preservation boards or authorities. In many cases, there are alternative installation methods available that minimize any visual impact on the historic aesthetics of the building. It is advisable to consult with experts in historic preservation and solar installation to ensure compliance with any necessary requirements.
Q: how efficient are flexible solar panels?
One I got about 3 years ago is about 50% as efficient as a glass panel I got about 0 years ago. Not exactly a scientific study, I know.
Q: How do solar panels affect the overall comfort of a building?
Solar panels can positively impact the overall comfort of a building by reducing energy costs, improving indoor air quality, and providing a more reliable and sustainable source of electricity.
Q: Can solar panels be used in areas with high winds?
Yes, solar panels can be used in areas with high winds. However, it is important to ensure that the solar panel installation is designed and built to withstand the specific wind conditions of that area. This may involve using appropriate mounting systems, securing the panels properly, and considering the orientation and tilt angles. Additionally, selecting high-quality materials and conducting regular maintenance can help ensure the longevity and performance of the solar panels in high wind areas.
Q: Are solar panels weatherproof?
Yes, solar panels are weatherproof and designed to withstand various weather conditions including rain, snow, wind, and extreme temperatures. They are built with durable materials and are tested to ensure their resilience against outdoor elements.
Q: I really want a projector but i hear they use a lot of energy because of the lamp. I want a good one to watch movies and play games on. but i don't want one that is gonna kill the lighting bill.is there like a solar panel or something i could use for it. PLZ HELP.
Do understand, that a solar panel is slow to pay for itself. Let's say your electric bill was $200 a month ($2400 a year). A solar system would cost perhaps $24,000 so you would actually have paid your first 0 years of electricity in advance when installing the panels. After that 0 years, you start to be ahead financially. It can still be a good idea, but it may not be the quick and cheap solution you were looking for.
Q: Solar Panels not working very well, they have faded. Is there any paint or anything else I can do to restore them? Thanks Eileen
Unfortunately Eileen the panels are bound to fade as its par for the course. Over time much like everything else (from an AC condenser to your knees and hips) everything starts to go south. When did you purchase and install your panels? If this was done within the past few years then something is definitely wrong, and you should have the manufacturer and installer come back and replace the panels....on their dime of course. Is the warranty on your panels still in effect? If so then its definitely something that they have to come back and take care of. There is a company I know of called Sun Electronics that has a 20 year warranty on their products, so if its worth anything you might want to buy your new panels/system from them. The panels around today are more efficient than those of years past, and with the cost coming down due to economies of scale and the tax incentives you might want to consider getting a new system. Sorry to let you down though Eileen!
