Q:Solar panel angle question..?
2.20 approximatey (2 /4 -- ish) X = (tan7)(8/tan45)
Q:are solar panels worth buying?
Depends where you live. Solar hot water is good for anywhere that doesn't get hard freezes, and will also work (slightly different technology) in colder areas, but will take longer to pay back. Hawaii probably has the best payback for solar water heaters of any state.
Q:How much do solar panels usually cost?
You can log in alibaba,i purchased about 20000watts 2 years ago and solar panels work efficiency is fairly high. I hope my answer help you !
Q:how many 45 watt solar panels would I need?
I doubt you will be able to get anywhere near the amount of light needed to run anything for 6 hours a day. You will probably need a battery or something as well. At the least, you will need 3 solar panels, but you will probably need more than that in order to charge the batteries to get it to last long enough.
Q:how many solar panels needed for Heater and AC?
Please excuse my bluntness, but you are not ready to ask these questions. This is a very complex issue. The how many question depends on what you expect of the system. Are you attempting to be off the grid? If so the system will have to supply all of your electrical needs, including those at night. You would need batteries. If you will be on the grid and want to supply all your electrical needs, your system will have to average the total daily usage. This will vary from one season to the next, so you will need to find out your annual usage. If you just want to reduce your electric bill, you need to pick the acceptable installation cost, and work with it to determine what it will buy In your shoes I would do some studying. Check out solar panels in the green search box above, and on the Internet. This will help you ask questions that are easier for us to answer.
Q:How many Watts of solar panels?
Running an oven or stove on solar is not a practicality; too much power is needed, use gas. Ditto, heating using solar electricity is not a practicality, and AC would also be asking a lot. The other things, within limits, might be do-able. You'll be needing as many solar panels as you can fit on. If I was you I'd consult a solar installer about how big your battery bank should be once you have decided how many Watts of panels you can put on.
Q:Solar panel, Home office and Tax write off?
The solar panels are a capital improvement. You can deduct 5% of the depreciable portion of the property as part of the home office deduction. You'd have to depreciate the solar on the same 39 year straight line schedule as the house itself. (The land value is never depreciated so you'll have to break that out separately.) Since this is business use of real estate, the depreciation is over 39 years, not the 27.5 years for residential rental real estate. That crunches out to a whopping $38 deduction per year for the depreciation on the solar panels. ($0,000 x .5) / 39 = $38.46 which rounds down to $38. If you're in a 25% tax bracket, that will save you a whopping $0 in taxes. Keep in mind that when you sell the home, the depreciation allowed or allowable will be subject to recapture. That is taxable income subject to a maximum tax rate of 28% even if you can exclude the gain on the sale under Section 2. For that reason you might wish to consider the safe harbor deduction new for tax year 203. You may deduct a flat $5 per square foot up to 300 square feet for a maximum deduction of $,500. That won't trigger the depreciation recapture (for the years that you use it, you can switch off year for year if you wish) and may reduce the likelihood of an audit as well.
Q:what do solar panels do?
The solar panels are made of solar cells. A cell is a small disk of a semiconductor like silicon. They are attached by wire to a circuit. As light strikes the semiconductor, light is converted into electricity that flows through the circuit. As soon as the light is removed, the solar cell stops producing power.
Q:Homemade Solar Panel : Hi! guys i want to know what do you think about Homemade Solar Panel?
Low cost solar panels are also extremely popular worldwide and China is a country that has been discovered to be excelling in this field as they manufacture the most economical solar panels when compared to any other country. Looking at the way things seem to be moving it seems that China will soon become a country to contend with because of their capabilities to manufacture things at extremely competitive prices. This fact is quite transparent for the simple reason that China appears to be getting more than double the number of orders. This can also be attributed to the fact that in spite of their low costs they have not only maintained but also improved on their quality too. For More Information You Can Refer To :
Q:how to chose the right solar panel for my home?
One will give you enough DC voltage to light a 25 watt light bulb, [ one 45 watt panel is around $400. ] Now if your wanting AC voltage You have to buy a inverter, 5 or 6 deep cycle batteries, a switch Cables to transfer the voltage, a place out side to store the batteries, instalation brackets for the roof A Permit to Install them
