If we do not consider the rebates that some countries offer on solar panels, the payback normally runs between 20 and 25 years. The long payback though ignores the increased benefits to the planet and the possibility of increased electric costs over that time period.
Panels will also degrade with time. Warmer climates may see a slightly longer payback period, due to the decreased performance of solar panels. I have several panels on my home and they actually produce more power in the winter months, despite the shorter daylight periods, due to the cooler temperatures
What else can I help you with?
How long does it take to charge batteries with a solar panel?
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.
How long does it take to charge 12V battery with 45watt solar panel?
That depends on the amp-hour capacity of the battery.
How to make a solar power at home?
take a solar panel & add wires on the panel & connect these wires to the small appliance!!!!
How long does it take to build a solar panel?
It doesn't seem that it takes very long at all, maybe an hour or two, depending on your work speed
What technology can you take to a desert island?
well, something that has very long battery life or just bring a solar panel connected to a socket
How long does it take to generate 375 watts of energy with a 1 square meter solar panel?
The amount of time it takes to generate 375 watts of energy with a 1 square meter solar panel depends on the efficiency of the panel and the amount of sunlight it receives. On average, a good quality solar panel can produce about 100-200 watts per square meter, so generating 375 watts may take a few hours under optimal conditions.
How long would it take a 200 watt solar panel to charge a 12V deep cycle battery?
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.
Can you use a 0.4w 4.5v solar panel to charge a 4.8v battery?
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.
How long will it take a 13 watt solar panel to charge a 12 volt battery?
The time it takes to charge a 12-volt battery with a 13-watt solar panel will depend on various factors such as the battery's capacity, its current state of charge, weather conditions, and efficiency of the charging system. On average, it may take around 8-10 hours of good sunlight to fully charge a depleted 12-volt battery with a 13-watt solar panel.
How long does it take to install a solar panel?
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.
How long does it take for residential solar power to pay for itself?
It usually takes a while. Although this may seem like as something bad, it will eventually pay for itself and will be a great benefit economically and ecologically. The time it will take for it to pay for itself depends wholly on the amount of sun the place gets.
Will solar energy run out?
No, solar energy will not run out as long as the sun continues to shine, which is estimated to be for billions of years. Solar energy is a renewable resource that can be harnessed for electricity generation through solar panels.
