Q:solar panel for 2 batteries(2 V)?
Taken at face value, it would take about 55 hours to re-charge a dead flat battery. However, you don't get 24hrs/day sunlight. Even worse, the output from a panel is only maximum when the sun is at 90 degrees to the surface. Let's assume you can find some way to track the sun. No battery should be allowed to discharge below about 50% so we can halve the recharge time. I would say about 4 days.

Q:Finding the output of a solar panel?
You need full sunshine from the sun, or a lamp that will give a light spectrum similar to the sun, a volt meter, Milli-amp meter, and a variable resistor of 0 to 000 ohms. The voltmeter test leads go across the solar cell leads. The amp meter leads will be in series with the solar cell. Let's say, positive lead of the solar cell to the the positive lead of the amp meter, the negative lead of the amp meter to one terminal of the variable resistor, and the wiper terminal of the variable resistor to the negative lead of the solar cell. Slowly decrease the value of the resistor until the voltage from the solar cell just begins to drop. Take note of the amp meter reading. This is about the high end range of the solar cell. You might want to begin with a micro-amp meter for the current meter.
Q:how many 45 watt solar panels would I need?
Lets say, for a simple approximation, that the 45 watt panel produces 45 watts /3 of the time and nothing the rest of the time. Each day, this will produce 8 hours times 45 watts = 360 watt hours. Also assume the battery charge controller and inverter waste half of that power, leaving 80 watt hours per day. If you use compact fluorescent lamps, that would allow you to burn 80 watts worth for an hour every day, or 90 watts for 2 hours, etc. That is a lot of light for a shed. You might consider using much less efficient tungsten filament lamps, but eliminate the inverter and choose low voltage (automotive) lamps that can run directly across the battery and lower the total cost, but give you only about half the light times time. The main advantage of the inverter might be that it would allow you to use small power tools or appliances in the shed. -- Regards, John Popelish
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:Has anyone gotten their solar panel rebates in Florida?
Do not count on getting the rebate soon or if at all. You should get on the list and wait until the funds are released. Good luck. Summary: Note: There is currently a waiting list for rebates from the Solar Energy Incentives Program. This program has received $5 million in federal funding from the American Recovery and Reinvestment Act of 2009 (ARRA). This funding will be used to award rebates to some of the systems that are on the waiting list. The state has applied for an additional $9.4 million in federal funding for this rebate program. Systems applying for the rebate at the present time will be placed on the waiting list. If additional federal funded is received, the approved applications will be awarded rebates based on the order in which they were received. FY 2009-200 is the last year of the solar rebate program and the last year the program could be funded under current authorizing statute. Florida's Solar Energy System Incentives Program was established in June 2006 (SB 888) to provide financial incentives for the purchase and installation of solar energy systems from July , 2006, through June 20, 200. A total of $2.5 million was available for FY 2006-2007; $3.5 million was available for FY 2007-2008, and $5 million is available for FY 2008-09.
Q:Solar Panel - DC motor - Rated Power ? Functionality ?
Wood? Steel tubing could be a lot lighter. Use the hardest narrowest tires you can find bicycle wheels and tires would work nicely and they can be had with really light disc breaks. As for a motor a golf cart motor is made to order. You can get an old electric golf cart and have almost all the parts you will need. Hell cover the roof of the cart with photo voltaic and have a ball. Note I stress weight savings as weight will cost you energy and with photos you won't have much to spare. You will need a battery pac of some sort lithium are a better choice than lead acid. there is a ton more to consider good luck with your project.
Q:Solar panel power question?
NO ! Pump needs 747 watts power. And you need to buy one more expensive DC to AC converter to make it work. Use solar panel at least has 000W output.
Q:How much do solar panels cost?

Q:I NEED HELP WITH MY SOLAR PANEL SYSTEM PLEASE HELP?
I think you need to take some basic courses on electricity. Usually, 8 volt solar panels are required to charge 2 volt batteries. The voltages of photovoltaic cells are set by the material they are made of, only current changes. If you hook up a 2 V solar panel to a 2 V battery, no current will flow, nothing would get charged. You would need some elaborate DC to DC voltage converters to charge a 2 V battery from 2 V solar panels. Solar panels can be connected in parallel or in series, as you've made the mistake of buying 2 V solar panel, you would have to wire them in series and have a charge controller that could limit the voltage of the charge. Did it ever occur to you that two 5 watt solar panels would not be able to provide the power needed by a 400 watt inverter? You're just running off your battery with your set up. Solar power is expensive power, you can not have solar without burning a hole in your wallet.
