- Q:Hi, I have in my sailboat 2 2 V batteries. I would like to buy solar panel(s) in order to recharge them. As i am in mexico and there is always high sun . i think it is a good idea.Usage of the batteries is very light . I have found 5-2V pannels with 80mA that fit in the sailboat. I want to know if and how i can have like 5 to 0 of them set together to charge the batteries and what other material would i need.also, i would like to know what happend if the pannels only send on 5V in a 2 V battery? Is it still charging but on 40 % of the capacity a 2 v pannel would charge or its just not doing nothing ?
- I don't know what you have avilable to you down there, but if you were in the states i'd say go to a camping supply store they have lots of solar options out today. check one link below
- Q:How can solar panels be integrated into building designs?
- Solar panels can be integrated into building designs by incorporating them into the structure or facade of the building. This can be done by installing solar panels on the roof, as awnings, or as part of the building's walls or windows. Additionally, innovative designs like solar shingles or solar glass can also seamlessly integrate solar panels into the overall aesthetics of the building.
- Q:Can solar panels be used in combination with wind turbines?
- Yes, solar panels can be used in combination with wind turbines. This combination is known as a hybrid renewable energy system. It allows for a more reliable and efficient generation of electricity as the two sources complement each other. Solar panels generate electricity during the day when there is abundant sunlight, while wind turbines generate electricity when there is sufficient wind. By combining these two sources, the system can produce electricity continuously, regardless of the time of day or weather conditions.
- Q:right now, you would need a suitable number of solar panels just to power house that can take up a lot of real estate. so my question is, is it feasible to create something that absorbs more of the suns energy like a magnet it would suck it up. the point of doing this would be so that we wouldnt need so much space so many panels just to power home for example.i hope thats coherent.
- Of course,in fact I read somewhere that they are studying butterfly scales or something because they are better than man-made solar cells.Whether or not this book was lying I don't know.
- Q:Can someone tell me the average savings you get PER solar panel installed? I do not have the money to invest in a bunch of them at once, so I am forced to buy one at a time, when I have the money. So how much can I expect to save after I buy the first one?
- No matter what or how you do it it is best to get off coal and nukes. So it cost a little bit of money you are buying 30 years of electric. How much will you spend adding in cost of living increases over the next 30 years? Solar really is pretty cheap if you take the time to do the long term math. If you use your cost at to days rates it does seem like a lot. But if you do the math like in real life with 3.5% compounded cost of living increases per year and 6.5% fuel increases per year. Well, you pay a lot more renting power. One other thing to think about and Al Gore keeps pointing it out is, Will your off spring be alive in 50 years from now if you don't buy the solar panel? Kind of like not going to the doctor because you can't afford the bill. Well I would rather owe a bill to a doctor that I will have trouble paying then not be alive at all to try. If you don't have the money to jump in and go full blown Green you should buy a starter system. You can get a system that can be expanded to 3000 watts (enough to power an energy efficient home). Would cost you about $8000 USD to get started and then you could add three solar modules at a time till you get it up to the 3000 watt max. And even have backup power. Or you could just buy a 000 watt system for about the same price and just add 3 of them over the years. There are many ways to get started. The deal is everyone needs to get started even if it is a small system. If all 50 million homes in the USA would install a small 000 watt system with 4 hours of sun light a day. We would provide (000 watts times 4 hours times 365 days times 50 million homes) 29,000,000,000,000 watts not from coal or nuke plants per year. I wonder if that would help?
- Q:Can solar panels be installed on water treatment plants or utilities?
- Yes, solar panels can be installed on water treatment plants or utilities. In fact, many water treatment plants and utilities are increasingly adopting solar energy systems to reduce their reliance on traditional energy sources and lower their carbon footprint. Solar panels can be installed on the roofs of these facilities or on nearby open spaces to generate clean and renewable electricity to power their operations.
- Q:Can solar panels be used in areas with limited access to electricity?
- Yes, solar panels can be used in areas with limited access to electricity. This is because solar panels generate electricity using sunlight, so as long as there is sunlight available, they can generate power. In fact, solar panels are often used as a sustainable and reliable source of electricity in remote or off-grid locations where traditional power infrastructure is not available or feasible.
- Q:Solar panels do good more then bad?
- Like any other materials, solar panels need to be manufactured. These components are usually imported, they use energy to produce and transport. However, once you install solar panels, they need little or no maintenance (except cleaning to maintain efficiency) and they use no other resources to produce power. Over their lifespan, they'll produce more energy than was used to be made, so on the whole good for the environment.
- Q:Making a solar panelI know there was a recommended wattage for the soldering iron but i cant rememberdoes anyone know?
- Temperature controlled soldering irons like Weller are best. They don't burn up if left turned on.
- Q:Pros and Cons if I get solar panels?
- Maybe. okorder /
