From start to finish, for a residential house. It could be done in a month.
Only a few (3-5) days would workers be on the roof.
No set answer to that. It depends on the capacity of the battery, the size and efficiency of the solar panel and the intensity of the sunlight.
it will take 1000 years ny tayaab javed
That depends on the amp-hour capacity of the battery.
take a solar panel & add wires on the panel & connect these wires to the small appliance!!!!
It doesn't seem that it takes very long at all, maybe an hour or two, depending on your work speed
It depends on how many solar panels you are installing, but only takes around one day to install them. It can be short as few hours or long as a two days.
well, something that has very long battery life or just bring a solar panel connected to a socket
A very long time. I would guess 48 hours of sunlight at the very least. Even that may not be enough to fully charge the battery. It really depends on how much amperage the solar panel is putting out.
Most likely not. In order to charge the battery to its nominal rated 4.8 volts, youreally need a source capable of more than 4.8 volts open-circuit.You need to take the solar panel and a voltmeter, and measure the output voltageof the solar panel with no load connected to it. If it's more than 4.8 volts, then itwill charge your battery.But . . .That's not saying anything about how long it will take. 0.4 watt is not an awful lotof power, and your solar panel will not even deliver that much before its outputvoltage sags to 4.8 . So I would think that this solar panel will not be an acceptablecharger for that battery.
Take the door panel off, remove the old reg. Install the new one... If you don't know how to take the door panel off, best to stop there
Hi, a good question. Solar Energy International is a non profit group that does research on solar power. They studied this problem for several years. The number of years varies, but runs between 1.5 and 6 years for a panel to earn back it's, "Embodied Energy." Many people I talk to argue that this is a bad omen for a panel, the reverse is true. The reason is this: We will always have electricity in our society, the question is what is the best way to produce it. If you built a generator that ran for example on natural gas, and it was very effiecient, say 95%, how long would it take to earn back it's, "Embodied Energy?" The answer is it never does, because after you manufacture and ship a generator like this, it then has to be fed natural gas to continue operating. At least the solar panel has the ability to earn back it's energy after a few years. Hope this helps. Take care, Rudy
The average American house uses less than 12,000 kilowatt hours a year and a 1 kW (kilowatt) solar panel system produces about 2,000 kWh a year. So you would need a 6 kW solar panel system to produce enough energy to fuel your house. Right now solar panel systems of that size would cost around $45,000 to buy and install. This means it would take about 37 years to pay off the cost of buying the system (income tax reductions included). The bad thing is the life span of solar panels today are 25-30 years so you most likely won't get your money back.
