You can run a 60 watt light bulb when the sun is shining. Or your can charge a battery and then run the 60 watt light bulb at night. It theory if you had 8 hours of sun you would be able to run the bulb for 8 hours off of battery. In reality because of losses you will not get 8 hours of bulb running time.

Answer by f100_supersabre
There are many on the web charts on stipulations for home/business.

60 watts at 12 volts is 6 watts at 120 volts with 100% conversion.
MOST inverters are only 30-60% efficient, plus battery losses. (Batteries are required to “balance” load and for when sun is NOT shining.)

MOST TV’s draw 120 volts at about 500 watts

MOST homes these days are wired for 100 amps at 240 volts which is 24,000 watts even though they seldom draw this much at any given time.
A single standard home circuit is usually 15amps at 120 volts or about 1,800 watts MAXIMUM.

No need to be afraid. The lamp is rated at 60W because of heat output not because the socket is 60W. The 10w cfl (compact fluorescent light) that you have is fine.

Answer by roderick_young
The price per watt is a figure of merit, but is not how the panels are sold, any more than a gallon of gas is sold by how many miles you will be able to drive with it. You purchase the gas at a certain price, then how many miles you actually get depends on what automobile you drive, and other factors.

In the same way, a certain model of panel is sold for an agreed-upon price. Let’s state it’s a 200-watt panel, and sold for $ 400. If the panel was rated in accordance with established standards, that means the panel will deliver 200 watts under best sunlight and temperature (that only happens about an hour a day, if that). So you can compute that the price was 400/200 = $ 2 per watt.

If the strong sunlight shines on the panel for 1 hour, then the energy produced is 200 watt-hours. This is where many people get confused. A watt is different from a watt-hour. A watt is a unit of power, like how strong a man is. A watt-hour is a unit of energy, like the work accomplished by that man in 1 hour.

The watt-hours or kilowatt-hours delivered are what light the rooms, run the appliances, or are sold to the power company. Getting those is a matter of having a good geographic location and installation.

I know if its a 4500 watt system that the cost per watt would be $ 6. and the cost for the installation would be added to your mortgage (

Answer by Matthew B
A solar power system includes, Solar panels + grid inverter + new power meter + installation.
Solar panel cost is not linear as you go up in size of solar panels.
Solar panel efficiency can be worked out by size and power output.
Price per watt does not relate to overall performance.
Total solar panel watts, your location e.g. average kWh/day solar radiation, the aspect of the solar panel and their angle is important. Solar panels should be facing the equator (N or S) and pitched at your latitude angle.
Some of the solar losses include grid inverter efficiency, cable losses, temperature coefficient (power output efficiency falls slightly at higher temperatures) and cleanliness of the solar panel surface.

Answer by Hockey ball
no it cant. good question though.

what kind of deep cycle is it? unless its an AGM, you cant keep the battery inside. all non-sealed batteries release vapors which are explosive.

also depends on the amount of usable sunlight. no sun… food goes bad even with a battery.

If we take a typical situation of approx 6 hours of usable sunlight during the day (remember, direct sunlight – no cloud cover), a 50 watt solar panel and a small fridge (that uses 2.2 Amps per hour):

50 WATTS ÷ 12 VOLTS = 4.1 AMPS
4.1 AMPS – 10% = 3.6 USABLE AMPS
3.6 AMPS X 6 HOURS = 21.6 AMPS in 24 HOURS

This means the fridge could run for 10 hours using a total of 22 Amps.

Answer by Peter W
If you need certainty, the short answer is no.

The much longer answer is Maybe.

I found a few very small refrigerators that use 90 watts or less (none had freezing functions, by the way) but that is only part of the story.

a) A 90-watt panel gets its full rating in direct, strong sunlight – so perhaps an average of 4 hours per day with the rest of the day getting less. If rated at 90 watts, assume that the net-average will be closer to 50 watts.

b) Discounting rainy days and assuming 8 hours average sunlight per day, you will realize 400 net-watts of power delivered to the inverter.

c) You will get at least 20% loss through the inverter. Your net-net will be 360 watts to the battery.

d) If the compressor runs less than four (4) hours per day you will be fine assuming a 90-watt fridge.

If the compressor operates for 8 hours per day, it will be using something under 8 amps per hour, and assuming a 90AH Marine (AGH) battery – and the fact that you do not want to entirely discharge the battery even if a deep-cycle – you will get 3.5 days of safe use with that combination. So of you can get the battery charged each third day you would be fine.

Or, install two such panels.

Good luck with it.

Hi,
Answer:
1059.5 watt hours or 1.0595 kWh.

Comments:
E= P*t (Power multiplied time = watt hours if power is in watts and time in hours.
E=224*4.73
=1059.5 Watt hours.
1059.5/1000=
1.0595 kWh.

Notice that the voltage is already a component of the power. That is, P=EI. (Where I is current in amperes.) The voltage is only important if you are trying to run some device at the solar cell voltage or, state charge a battery. Normally you would have an electrical device between the solar cell and the driven device(s) to convert the solar cell output to the type (AC maybe for a driven device or a lower voltage to charge a battery.) and voltage necessary for the driven device.

Do you mean the Sharp ND-224-U1F? That module has a PTC (“real world”) rating of 197 watts. If you are using a grid-tied inverter with it, take away another 5-7% of the power. But the answer is the same, about 1 kWh, average daily output over a year. Late Spring will be more, early Winter will be less.

yes you could, here is more info about solar panels if interested

Answer by Amy
You would still need a charge controller and battery to store the power you generate, and an inverter to convert the DC power to AC that your Computer needs. If you figure the panel could make 30W for about 5 hours, and you would have about 30% losses throughout the system, you could generate about 105 watt hours (wh) (30W x 5 hours – 30%). A laptop personal draws as much as 80W (newer ones use less), so if it ran for 1 hour, that would use 80wh. You could run it for just over an hour. You’d need about a 18 amp hour battery (105wh x 2 (you never want to drain more than half way) / 12 volts = 17.5ah).

Answer by roderick_young
750 cold cranking amps might be just a 100 amp-hour battery. And even so, you would not want to draw the charge down below 80% during the day of heaviest activity. So a automobile battery is about right.

If you live in Arizona, maybe you can go smaller, 50 AH sealed lead-acid.

Answer by Mr.357
I would get a deep cycle marine battery for a trolling motor. A small one should be enough. You should have enough battery to open the gate for about 3 days without charging since depending on where you live, you might not have any sunlight for 3 days or so.

Answer by JOHNNIE B
Normal power is measured in kilo watts per hour. It sounds like 10 watts would be very small to do anything.

Answer by Annon
Watts is a measure of energy per second. IE joules per second. 10 watts = 10 joules/second

Car battery capacities will be measured in mAH (milli-Amp hours)
capacities vary greatly even though they will still take a fair while to get charged by such a little power charger.

Answer by jleblanc42
It will put out 10 watts in full sunlight at noon, less at other times of the day. That means 0.83 amps, so just divide the battery capacity (in amp-hours) by 0.8 and you will get an approximate charging time under full sun.

Answer by sparkchaser
A typical lead-acid battery can safely be “trickle charged” at C/100 rate, where C is the capacity (if you are speaking automobile battery, that is about 50Amp-hours typical). C/100 for a 50Ah battery is 500mA, so 350mA will not injured it. The trickle-charge just overcomes losses due to battery self-discharge, which is fairly high in lead acid batteries. Your current is also limited by the internal impedance of the solar cell and diode.

On a small, 7Ah, 12V battery then, yes, you do run the risk of overcharging if you leave your solar panel connected because you will be charging at about C/20.

Answer by guru
the normal charging rate for batteries is C/10, C/100 is used for keeping the battery fully topped off
you need a controller if the battery is small
small meaning less than about 100 times the charger’s capacity
so for 350 mA a battery of more than 35 AH would not “absolutely” need a controller

however it is always superior to have one!
