Can you upgrade the solar panels to a higher wattage or stack two or more together to possibly decrease the charge time?

I don't know about stacking but you can chain the cheap Harbor Freight panels to get 45 watts and use that to recharge. There are some great websites and youtube videos on how to maximize power output from solar panels.

Yes, you could replace this panel with another of higher wattage, as long as the open circuit and loaded voltage of the new panel is similar to the ratings of the 30W panel. The charge time will then only be limited by the built-in charger. The 30W panel does not have a blocking diode that I can find, so you cannot just parallel two panels. Putting two panels in series would also not be recommended as it would likely damage the charger.

You can connect at least 8 solar panels of 100watts each and I have 15 deep cycle batteries on that. You need cables mostly and maybe some safety fuses if you want.

Not well you would need like 6 of them. I would go with cheap solar panel and run the power to an inverter

It depends on where you live and how much sun you get. Based on 140W 24/7 the 300W "kit" won't be enough. That doesn't mean you couldn't do it with more panels. Just don't buy a "kit". That comes with a dedicated charger for the wattage the kit comes with. Check on line or with someone who can give you the calculations you will need for wattage and but individual panels and then size a charger for your needs. I had to do the same. The panels that come with the kit are top notch and can be bought by themselves.

If you plan to add more panels, you will need to use a bigger charge controller or stack another charge contorller. This charge controller only only fit 240W and 480W for 12volts and 24volts system.

Yes and if you have or want to buy more solar panels you are able to link them for faster charging

It only has one incoming (Solar Panel) plug hook up and two outgoing plug hook up.It is rated for up to 100 watts of solar power and 7 ampere of current so if you have lower wattage panels I would think you could add incoming lines to the plug hook up up to the Max of 100 watts.The same would go for the outgoing lines but the lowest battery would pull the highest charge rate until all were equal. If you are looking for low no load charging then it might work for you.

YES. WE SELL THEM FOR THAT PURPOSE, HOWEVER IF YOU ARE USING THE BATTERIES FOR ANY PURPOSE, THIS 7 WATTS WILL NOT KEEP UP. SOLAR HOWEVER IS ALWAYS A FUN EXPERIMENT. IF 7 WATTS WON'T KEEP THE BATTERIES CHARGED, ADD MORE WATTS (PANELS) (OR LARGER WATTAGE PANELS). YOU COULD CHECK OUT OUR INFORMATIVE WEB SITE AT www.sites.google.com/site/solardoityourself, or even call me directly at 305-900-09596. thank you

Yes BUT... You have to buy a charge controller that can "step down" the 36 volts from the panel to 12 volts for the batteries. Look at Morningstar controllers and or go to Morningstar's website to get the specs on an appropriate controller for your application.

I have used this unit to power my laptop for at least two hours. I am sure you could use a solar charger to increase that time, I believe there are either versions of this type of device that are sold with a solar charger, you cold buy one or make one with parts from amazon.

Only if you have a battery which you charged ahead of time which can power said appliances for the desired amount of time. This panel set could not power those items outright, you'd need a much larger set-up for such a task.

Technically you could, but you'd need a lot of 'em. Grid-tie systems tend to have more power. If there's one near you, I'd suggest contacting a local solar power shop to talk about grid-tie; those systems are much more complex and regulations vary from location to location.

i use the solar to charge a battery then run 12 volt lights off batteryif your using during day try itu may have to add battery for more reserve

I don't think you can connect 1 solar panel to multiple controllers effectively at the same time. I would rotate the batteries as needed for charging; only one controller would be needed.
1199237
Yup. But the higher Wattage you get the better, and more powerful devices it'll charge faster. Also, if you get a power bank, and change it with the sun, that works even better, becasue then you don't always need to be in the sun. Hope this helps!

You are more likely to over charge the battery with a 12 volt unit. Just ensure the whole solar array is in the sunlight for optimal charging.

You certainly can. Think of those big solar arrays...they are several individual panels connected in a system to provide a certain wattage of output.
