Will use of a recommended solar panel(100 to 120 Watts) keep the humless generation running continuously of a period of up to 8 hours?

That is a much more difficult question to answer and depends on how much power is being pulled from the generator. The generator is rated for a capacity 50Ah (600Wh); if one did the math dividing those numbers by the 8 hr solar charge time, then charging would supply 6.25Ah (75Wh) per hour. So, is the use during those 8 hours more than 6.25 Amps or 75 Watts per hour? Chances are there are times when use would exceed incoming charge and times when it would not.

Ya you can run this with photovoltaics. The only thing is that this is 120VAC so you will need an inverter from the solar panel to the pump. More than likely there are DC pumps out there and you could hook directly to it. It will start pumping when the sun comes up and stop when it goes down. If you want it to continuously run then get a larger solar panel --&gt; charge controller--&gt;battery--&gt;pump. My estimate since pump is 6 watts get at least an 18-20 watt panel then a battery that will last you through the night, 6 watts * 18 hours * 2 (oversize it) = 216 watt*hour battery.

Battery in question is 100ah x12v = 1200 watt hours. This panel can provide 144 watts per hour for battery charging purpose. Rule of thumb batteries should not be drained more then 50% or maximum 80% otherwise battery life will be compromised, so we will consider 600 watts to be charged. 600 watts divide by 144 watts = 4.16 hours. Since this panel is 24 volt and your battery is 12v - MPPT charge controller is highly recommended. MPPT charge controller can accept higher voltage (24~36 volt) from the solar panel and charges a lower voltage battery (such as 12v). Morningstar SS-MPPT-15L will be a good charge controller for this setup. Battery in question is 100ah x12v = 1200 watt hours. This panel can provide 144 watts per hour for battery charging purpose.

Use a 45 watt panel connected to battery with controller. Would not recommend direct connect (solar to pump) unless very small panel. Try a 5 watt and see. This still might be too much electricity.

You will need a deep cycle battery and big enough inverter to run it use solar panel to keep battery charged

The solar panel is the only power source for the unit. The battery life is dependent on how many times per day the unit is activated.

Depends on the wattage of the load and how long you will run in hours. It will work with a 100W panel fine. You will need a charge controller like the Morningstar SS-20L-12V SunSaver 20 Amp Charge Controller LVD. If you plan on running AC device you will need a little DC to AC inverter as well.

Yes and no. The better question is how the solar will be getting set up. If you use your panel to charge a battery and use the battery itself to power the light, then you will be golden, the panels will absorb what they need during day so when it gets dark the light can keep going off of the battery reserve. If you wanted to hook the light directly up to the panels THEN you would need the full 250watts, and it would only work in direct sunlight, you see? the goal is not to have enough power strictly from solar panels, but to have enough to charge a battery with the panels and use the battery with an inverter to power intended devices. Long answer short, buy a cheap deep cycle battery to hook an inverter up to, and hook your light up to said inverter, with this set up your light should work just fine. Hope that helps virtual pal.

The inverter is needed to run household AC appliances. If you do not need to run AC appliances you do not need an inverter. A 100 W solar panel will give you about 300 to 400 W hours a day of power to a battery. What do you need the AC for, a small microwave needs the 1000w inverter, a TV can run on 400 W or less. Remember you need a battery you cannot run an inverter straight from the solar panel.

The solar panel kit comes with three 15 watt solar panels. Simply connect your solar panels to your 12 volt DC storage battery, and then use at least a 300 watt power inverter to power your 120 volt AC device.

Of course friend, the panel is high efficiency, full sun generates 22 volts, you need a charge controller 12 Volt so you do not overload the system, it will keep you charged and when the battery is charged, disconnect, which prevents damage to your batteries!

I use a 10 watt solar panel to maintain my two 12 volt deep cycle travel trailer batteries with a battery tender monitoring the charge. The batteries are always fully charged and ready to go when I am.

I would say most likely not because as the batteries recharge the unit would bounce on and off as they recharge/discharge. Solution is to increase your battery bank size. My APS1000-12 has been working for over 2 years 24hr a day. But I have a bank of 12 batteries and monitor it daily to prevent totally discharging them down to 10.5 volts. This time of year my solar panels don't produce the amps as in summer months... It's a great unit but remember for every amp produced on the 120 volt side it pulls 10 amps on the 12 volts side.

This is an excellent panel. Puts out good voltage with very little light. As a personal rule I have found that one watt solar should equal one A/H battery so the 55ah would be the best choice. Google for"Solar Calculator" but all of these will ask you to define the load before they give you any info.

Yes with a charge controller and about 72 to 86 hours of constant sun light. For more than 60 Ah you should use 3 of these panels and always a charge controller.

I think you will be OK. If you do the math, 6X200 = 1200 watts. That's easily handled by wattsup. Be careful to connect the solar cells to the "source" end, also I would use a diode to prevent any chance of backflow, just as a safety feature.

In my opinion I would work backwards first. AC Energy Needs: What do you need to power? How many watts? Yousay laptops, radio, and possible fan (just kidding). None of those are big energy hogs. So you could probably get by with a system that outputs a continuous 100 watts. On the safe side lets say 150 watts of continuous AC power. OK, so you need an inverter (converts DC power to AC power) that output at least 150 watts of continuous power. There are lots of good inverters in this range. I suggest one that has a built in fan, high conversion efficiency, and an alarm for low power supply voltage. DC Energy Source: Solar panels output DC energy; however, their out put varies with time of day, cloudiness, and much more. You need a continuous power source. In steps the battery, a power reservoir or buffer. We are not talking car batteries here, as they will not handle the deep discharges and recharges that you could subject them to. Deep cycle batteries are what you want. If you read Northern Arizona Wind & Sun's battery FAQ (http://www.windsun.com/Batteries/Battery_FAQ.htm) you will fidn they recommend AGM batteries, such as these: UPG UB12350 Group U1 - AGM Battery - Sealed Lead Acid - 12 Volt - 35 Ah Capacity - I2 Terminal. Charging the battery: In steps the Solar Panel. Simply put you use the solar panel to charge the battery. You will also need to put something in between the battery and the solar panel(s), such a charge controller (avoids over charging) or diode (prevents charge from batteries leaking back through to the panels). Of course, you also need the best direct sunlight you can get. Mostly, that is what you need.
