- Q: I thought they were going to make solar powered cars and solar power plants among other things. It was only nearly 0 years ago that solar power was the big thing. Just curious, why did it die out?
- they still make them,i have them on my camper to charge the batteries, they are not cheap, however. you can get them at r.v. supply stores. in fact the ones they make now, are quite efficient, many people in the countryside use them for their homes, i dont know why the development for cars is so slow, though.
- Q: Can solar panels be installed on desalination plants?
- Yes, solar panels can be installed on desalination plants. Solar energy can be harnessed to power the desalination process, reducing the reliance on traditional energy sources and making the plants more sustainable and environmentally friendly.
- Q: Can solar panels be installed on a shipping container?
- Yes, solar panels can be installed on a shipping container. In fact, shipping containers offer a suitable platform for solar panel installation due to their large surface area and structural stability. This allows for efficient utilization of space and easy integration of solar panels into various applications, such as off-grid power systems or mobile energy solutions.
- Q: all i want to do is provide enough electricity for 2 fluorescent bulbs i was looking at some 80 watt panels how many of those would i need and what else do i need for storing the electricity for use at nite? and how much would it all cost?
- The solar panels are made in China because there are fewer environmental regulations and cheap coal power. It takes a lot of energy to melt silicon and there are toxic waste products. It would be three to five times more expensive to make the panels in the US ( three times is just for reprocessing the toxic wastes ). Solar cell made in China are about $2 a watt, perhaps as low as $ a watt but in truth the claims for $ a watt or less solar panels as in thin film solar panels have much lower efficiency and require perhaps ten times more surface area.
- Q: how to make a solar panel without buying any kit?Any things at home that can be used for solar panels(what are they?)procedures how to make a solar panel
- Homemade okorder /
- Q: What are the supplies needed in a solar panel field, i know there are the panels. But what about batteries, and converters. Possibly other things, and how many will i need, for a certain amount of panels?
- Short answer.. alot. A solar field is a big undertaking, and you'd be better off going with a solar consultant. I found this site and would recommend their services as they offer consulting, and are pretty big into solar (or atleast in my area..)
- Q: Can solar panels be installed on oil or gas facilities?
- Yes, solar panels can be installed on oil or gas facilities. This practice is known as solar integration and is becoming increasingly common as oil and gas companies aim to reduce their carbon footprint and adopt renewable energy sources. By installing solar panels, these facilities can generate clean electricity and offset some of their energy consumption, leading to reduced greenhouse gas emissions and environmental impact.
- Q: Harbor Freight sells a 75 watt solar panel, a surge power inverter, and deep charge batteries. But no one there can tell me how to put it all together. I want the end output to be a simple power bar that I can plug my devices into. I live in an apartment so I can not wire it directly into the grid. Please only serious responses. Don't waste your time and mine.
- i wouldn't. - harbor freight isn't known for the best quality stuff. - 75 watts assumes roof mounting, at 90 degrees to the sun, on a bright day. you're going to get considerably less. and only when the sun is highest in the sky. maybe you should look at, your computer, for example. if you're using it for 4 hours, and it has a 500 watt power supply, and you add 200-500 watts for the monitor, and some for the printer, modem, etc, you'd use 5kw that day. your 75 watt panel, generating maybe 50 watts at most, for maybe 4 hours when the sun was highest, and shining directly on the panel, would generate 200 watt hours. it would take 25 days to generate the electricity you'd use in single day. in the winter, you'd be pretty much out of luck. there just isn't enough bright sun. clearly, it's up to you, but there's a harbor freight near me, and i'll not be rushing out to get such a system. further, most appliances are quite voltage sensitive. you really do need to have the voltage in the 0-20 range. too much out, either higher or lower, will shorten the life of appliances at best.
- Q: I got an 8v solar panel for a project today, the only problem is that it came without any wires attached to it. Now i don't know what type of wires i should use and if i should solder them on or if i should use epoxy instead. Can anybody help me out?
- 6 gauge wire would be a good size. Just solder it on and run it wherever you want.
- Q: Do solar panels require a battery for storage?
- No, solar panels do not necessarily require a battery for storage. While batteries can be used to store excess energy produced by solar panels for later use, it is not a mandatory component. Solar panels can also be directly connected to the electrical grid, allowing the excess energy to be fed back into the grid and credited to the owner.
