Q: I want to buy a solar panel kit but I'm unsure of how it works. Basically I want to run my entainment set, Xbox, cable box, 46 led tv, and some desktop speakers. I went online and found a kit for like 250 or something like that at homedepot and was wondering if that kit is worth the money or go bigger or something.: I okorder to get more information on the subject.

Q: Can solar panels be installed on walls?: Yes, solar panels can be installed on walls. While they are commonly mounted on rooftops for optimal sun exposure, they can also be installed on walls using specialized mounting systems. Wall-mounted solar panels are a viable option for locations with limited roof space or where the roof is not suitable for installation.

Q: The ancients used skylights for light in lieu of electricity. Light was used for drying, even cooking foods and drying clothes. Solar clocks/sun dials were once popular but now we have battery operated clocks. Where have we tapped into any of these resources since the outdated solar clothes drier nicknamed the 'clothes line'?: As your question notes, there are other ways to derive power from solar energy other than just using solar panels. One such way that has grown rapidly in recent years, is solar thermal generation. Solar-thermal uses mirrors to collect sunlight and concentrate it at point to generate intense heat. This heat is used -- just as in traditional fossil fuel plants -- to boil a fluid, thereby creating steam pressure, which drives a turbine that generates electricity. Solar thermal has some advantages over traditional solar panels. It's collectors (i.e. mirrors) are cheaper to manufacture than solar panels and last longer.

Q: How do solar panels affect roof ventilation?: Solar panels can have both positive and negative effects on roof ventilation. On one hand, solar panels can provide shade to the roof, reducing heat gain and potentially improving the overall ventilation of the roof space. On the other hand, solar panels can obstruct airflow and create a barrier that hinders natural ventilation. Proper installation and design considerations are crucial to ensure that solar panels do not negatively impact roof ventilation.

Q: Hoping to find instruction, materials list and hardware needed to construct solar panels myself, how many and make it happen instead of talking about it: Silica based solar cells are not the kind of thing you whomp up in you basement. Here are a couple ideas for solar systems you can build and install yourself. Take a 4 x 8 sheet of /2 inch plywood. Frame sides with 2 x 4's. Screw tin cans in a staggered row (checker board) pattern inside frame. The more cans the more heat you get so place them nearly touching. Paint cans and entire assembly flat black. Cover top with glass, plexiglass (best) or heavy mill clear plastic (cheapest)Place on roof. Drill 3-4 inch holes in opposing sides. Run pipe or tubing into house. Attach to small low speed fan. The black paint will absorb sunlight and heat. The air moving through box will carry heat into house. It's a cheap efficient way to help heat your home. You can vary size and shape of box to fit your roof. If you use more than one box, hook them up in series. More boxes mean more surface area means more heat. To heat water. Take a steel tank. A car gas tank works well. It is galvanized so it won't rust, is cheap, and easily available at any auto salvage yard. But you will have to flush in throughly to remove gasoline odor. A steel 55 gallon drum is easier to work with but may cost more. Paint exterior of tank flat black. Weld/glue/clamp water pipes to tank. Place on ground in area that gets lots of sunlight. Attach water supply to tank and route discharge pipe to house or appliance. Black painted steel absorbs heat from sun light and heats water. In spring and fall you get warm to hot water. In summer you get scalding hot water and in winter you get cold to luke warm water. Both of these solar powered systems are seasonal and their output varies according to location and climate, but they are very inexpensive and easy to build and provide FREE heat and/or hot water for many years with little or no maintainence.

Q: How do solar panels affect my electricity bill?: Solar panels can significantly reduce your electricity bill by generating clean and renewable energy from the sun. By harnessing solar power, you can generate your own electricity, thus reducing reliance on the grid and lowering your monthly utility costs. In some cases, solar panels can even result in net metering, allowing you to receive credits or payments for surplus energy that you feed back into the grid.

Q: i have a fountain system that has a small electric pump. its made to be close to a house but i want it across the driveway and i dont want to run electrical over there.is there a small solar panel that i can get fairly inexpensive to mount on a nearby tree and be able to plug the pump into it?: More okorder /... (... or search portable solar panel) And probably under a tree isn't a good placement for a solar panel. Good luck!

Q: What is the most powerful solar panel made?: There are various solar farms that run turbine generators that have some rather large arrays. I suspect they'd be in the southwest but i've seen pictures of them covering a few acres. You won't find very large panels because its best to keep the panels small and just have a lot of them. This is because its much easier to have a thousand 0m^3 panels then huge 0000m^3 panel because you achieve best performance when you can align the solar panels to always face the sun. With a huge panel, you would need it to be high off the ground so it can manuver around. Small ones can all be menuvered on a small scale only a few feet off the ground so they can all be pointing towards the sun to gather the most light.

Q: Can solar panels be installed on a school or university campus?: Yes, solar panels can be installed on a school or university campus. Many educational institutions are adopting solar energy as a sustainable and cost-effective solution for their energy needs. Installing solar panels not only reduces greenhouse gas emissions but also provides educational opportunities for students to learn about renewable energy. Additionally, it can save the institution money on electricity bills and potentially generate revenue through excess energy production.

Q: I live in the UK, I have no savings (so would have to take out a loan of about ?8000), I don't know how long I plan to stay in my house, I might want to move in a year or two to take advantage of a better job so I want to keep the option open of being able to sell my house without having to pay off the cost of having the panels fitted (which I probably won't get back on the increased value they add to my house).What are the main advantages of having solar panels?What are the pitfalls the ever so eager cold callers with quotas to fill don't tell you about?Basically is it worth having them?Thankyou.: If you're talking about photovoltaic panels, for making electricity, they're very expensive. Around here I think it runs around 2 bucks a watt of capacity, just for the panels. Then they have to be installed of course, which means an electrician has to be paid, and you need an inverter also. You can also spring for a bank of deep cycle batteries if you want to be able to store the electricity from the panels to use at night or on cloudy days, but that adds another very large expense. Now if electricity is very, very expensive where you are, you could maybe pay this off in a few years, but I doubt you could pay off 8000 pounds worth of this stuff in only a couple years. If you're talking about solar for water or air heating, well, that's another deal. But those kind of setups cost a lot less to put in, I can't see anyone paying that much for it.
