Q:DIY single solar panels with outlets?

Q:How much for a 8kwh solar panel system?
Figure 8 hours of sun per day, so 8 kW-hr is a rate of kW, which is a medium sized panel, probably not enough to operate your house totally, unless you have a very small unit. Averaged over 24 hours, that is power at a rate of only 300 watts, enough for a TV. Average US home use is .2 kW, which over 24 hours is 29 kW-hr, plus you need extra for cloudy days, peak demands, and to charge batteries. You have to decide off-grid or on-grid, and if you want to (and are allowed to) sell excess power to the power company. Off gird, the cost of batteries and charge controller are a large part of the cost. On-grid, you have to purchase equipment approved by the power company to match your power with the grid. Panels will cost about $3 per watt, so for 000 watts that is $3000. Double that for installation, then add in cost of charge controller, inverter, batteries, etc. The last items depend on your alternatives, see paragraph above. .
Q:Help with Home Solar Panel System?
Himin Solar can help you design and install home solar panel system.
Q:what is the best way to go solar?
is your place has enough wind or sunshine ? the turbine is not easily for maintenance. the solar panel is more stable, one broken panel willl not affect the whole system much
Q:How to build a solar panel?
Building solar panels is not really a do it yourself kind of job. They are made in high tech factorys with specialized equipment and experianced engineers. It would probably be cheaper and easier to just buy some panels rather than try to make your own.
Q:Could solar panels contribute to global warming?
Claire's argument doesn't make much sense to me either. First; Claire is talking about the second law ('you can only lose or break even'), not the third law ('you can't get to absolute zero'). Easily confused, but not that important! Putting a solar panel down _can_ increase the heat absorbed by Earth. Everything has an 'albedo' (the proportion of incoming light it reflects), and Earth's average albedo is about 0.3 (ie 30% of incoming light is reflected, most of which leaves the atmosphere straight away). By putting a 0.05 albedo solar panel down on a 0.3 albedo surface, you increase the amount of sunlight that is absorbed by Earth and therefore contribute to warming. This heat is re-radiated at the Earth's temperature, in the right wavelength range to be absorbed by greenhouse gases too. If you put a panel down on equatorial ocean, or a black roof, however, there is pretty much no effect (since the albedo change is small). Also, the heating effect only lasts as long as the panel is there. Most panels are estimated to last 50 years, meanwhile CO2 has a mean lifetime of 00+ years. I did some maths and found that the 00 year averaged change in radiative forcing for solar panels was negative compared to the UK electric grid, because the reduction in CO2 emissions has a larger effect than the change in albedo. If I have spare time tomorrow I'll redo the calculations and share them. The albedo change has to be considered though!
Q:adding more solar panel & battery?
That charge controller is notoriously cheap and burns up easily. If you are going add solar panels, also buy another charge controller to go with them. They can both be connected to the same battery bank. I don't believe the kit comes with batteries, so you would buy whatever size 2V battery bank your power requirements call for. The size of the inverter depends entirely on what you are going to power with it, not the size of the panel array. As long as you are not powering anything that is over the 300W rating, you don't need a new one. Just be sure to check the details of the inverter, is it 300W continuous, or can it handle up to a 300W surge? Also, it's a modified sine wave inverter instead of a pure sine wave inverter, so don't plug any sensitive electronics into it. They may not work, or you may get a buzz or hum from it.
Q:Nuclear reactors vs. Solar panels?
You should research nuclear reactors and their emissions. Mostly it's waste heat, and if they use a water-based cooling reactor, there can be significant emissions of water vapor. Some might consider the spent fuel an emission too. Waste nuclear material disposal is a problem. Research it. Solar panels have no emissions during operation, but there is some nasty stuff emitted when they are manufactured. 2: Maintenance of solar panels is pretty straightforward: keep them clean, trim overhanging trees, shrubs, etc., check for and clean corrosion, contaminants, etc. regularly. Maintenance of nuclear power plants, so far, is a full time job for many technicians and engineers. The recently developed portable (the size of a shed) nuclear generators claim zero maintenance for 20+ years. That's a big improvement.
Q:what are bad things about solar panels?
They're really expensive. If you want it for practical use like a house or car powering system. They're bigger than like a battery if you're comparing size to power. Like a car battery can produce more energy than a 6 x 4 panel (just an example)
