Q:Anybody install solar panels themselves?
If you're in San Francisco, then the price of labor is going to be high. It's still legal to install your own, but you'll need to pull a permit, and get an inspection. If you hunt around on the PGE website, they'll guide you as to requirements. Aside from a standing-seam metal roof, the easiest install would be over asphalt shingle. As with any roof penetration, flashing and sealing the holes is critical.
Q:Solar Panel Charging?
With a 2 volt power source (solar panel, battery charger, vehicle charging system, etc...) you can charge three 2 volt batteries in parallel circuits then switch to a series circuit through a series/parallel switch to get 36 volts output. I've done this with my electric scooter so I can charge it with my pickup through the lighter socket when I'm away from home. It works great! When at home I just leave the switch in the 36 volt position, plug the charger in the wall receptacle and the charger puts out 36 volts. Actually 2 volt lead acid batteries have 2.6 volts when fully charged so the charging source has an output of 3.6 to 4.2 volts to effect a complete charge. In the series circuit the fully charged batteries would put out 37.8 volts so the charger would have an output of 40.8 to 42.6 volts.
Q:Solar panels IRS refunds?
The Tax Lady is almost always right, but I must disagree on the $500 limitation concerning a solar electric system (from the price, it sounds like that's what the original question was about) installed in 20. If there was such a change, there would have been an outcry on the solar installers' forum I visit, just as there was jubilation when the limit on the tax credit was removed a few years ago.
Q:why aren't solar panels for your house more affordable?
You okorder.com (or any other website you can find in a search engine) to get a list in your area. Good luck!
Q:Will my 8watt solar panel charge a car battery and how fast?
welcome to the wonderfull world of solar! you probably have a 2Vdc 8 Watt solar panel, to figure out its charging amps capability we do this equation Watts/Volts=Amps 8watts/2Vdc=.5Amps this is a conservative figure, since solar panel ratings are calculated using winter time sunlight, sunny locations and more daytime hours will give you higher amps. a typical good condition car battery is rated at 40Ah (Amp hours).to find out the charge time, we use the following formula; Amp Hours/Amps=T where T is time in hours 40Ah/.5A=26hours this is charge for a single battery, two batteries will double to over 52 hours. lets compare to charging a battery with your car, a car alternator puts out about 60 amps but usually run about half capacity. 40Ah/30amps=.3Hours! An alternator is far more efficient so charging with a small solar panel is best as an alternative or for low power applications. As far as using an inverter to power a TV, we can calculate how long the battery will last by using the original formula. a typical 9tv will use 70 watts 70watts/2Vdc=5.8A 40Ah/5.8A=6.9hours this figure is by drawing all the power from the battery, voltage inverters have a safety feature that will not let you discharge your battery all the way, so 40Ah battery will power a 9 tv for about 4.5 to 5 hours.
Q:How efficient are solar panels?
Solar panels are 5-30% efficient in turning light into energy. I'm not sure why it isn't 00%, but methods are constantly improving, and the panels are getting more efficient with time and research. Solar panels work with photovoltaic (PV) cells, which are made up of two very thin layers of semiconductor with a middle junction layer. The kinetic energy in light photons create a current that flows into whatever electrical cord it is attached to.
Q:Reflectors or mirrors around the solar panels.......?
In the 70's when silicon was really expensive, they played with using fresnel lenses to focus the sunlight on small solar cells but these panels had to be on heliostats and aimed directly at the Sun. These days, with nano-technology, there's a renewed interest in the concept but the fundamental weakness is that there are diminishing returns, at some point, it's just less expensive to have more solar cells.
Q:45 Watt Solar Panel Kit Harbor Freight?
I don't have direct experience with the Harbor Freight panels, but have heard that they are agressively rated - i.e., the three 5-watt panels are really 5-watt panels. The 80-watt panel is likely to be a serious panel, rated according to standard test conditions. It will also be more durable, and probably have a warranty of 20 years or more. There's really no comparison. If your goal is to experiment with solar electricity, then get the kit from Harbor Freight (or Northern Tool, or any of a handful of other places). If your goal is to save money, generally you will need a larger scale than 80 watts - several thousand watts being the norm. And the payback time will be measured in years.
Q:Life expectancy of LEDs and Solar panels...?
LED's 6 years or longer
Q:Do they make solar panels like this?
Solar panels only put out electricity when they are in the sunlight. If you need electricity after peak solar hours, you will need a battery storage system or a connection to the grid. You can run a DC device directly off of solar panels if the device uses the same voltage and amperage that the panel puts out. Your 600W lights use a ballast that takes AC current and will not work with the typical panel. Also, a 600W light will take at least 3 high output/high efficiency panels to run, and you will need more than that if you want to store energy in batteries. You are talking at least 60 sq. ft. of solar on your roof. Aside from the power you need, you are also asking for an AC current, while most solar panels put out a DC current. This is what inverters are for. There are some newer panels that output AC, but you are still talking about a lot of PV to power your needs.
