Can I create 500watts from 60watts solar panel?

Can I create 500watts from 60watts solar panel?

If I get a solar panel consists 36 3x6" cells which produce 0.5v, 3.6amps and 1.8 watts each (Which will be total 17v and 60watts)
I need 12 volts DC to charge a battery right? and a battery gives 12 volts AC to the inverter which it converts in 500watts or whatever it's capable of.
Can I give DC 12v to inverter (Directly through inverter's + and - Terminals) to create 500w or not?
and if no then is there any electric generator that run with electricity instead of patrol or diesel so I can use 100w or 200w to produce 1000w less or more.
If both of them are just random thought without any relationship with reality then is there any other way to use low level solar panel to produce more electricity?
If you don't understand what I want to ask please tell me I'll describe it in more details.

Thanks

You have your terminology mixed up. A Battery delivers DC voltage,

No you obviously cannot get a continuous 500watts from a 60 watt panel.

However from a 12v battery you can get very high wattage - for a short period. e.g. A 12v car battery produces well over 500 watts when a starter motor is turning the engine.

It is a normal practice for boats etc to charge batteries from solar and use the power later.

I think you had better give us the detailed question!!

Actually I use maximum 500w power in my personal room I don't want to use My other roommates electricity more likely I don't want to have any connection with them so I want to have my personal electricity producing solar panel. I know that I can't get 500w from 60w but I want to know that can I have some big battery bank which will continuously provide 500w like if I can have two set of good battery bank which can provide 500w for 10 hours each set. I'll charge first set in 10 hours meanwhile use the second set and when second set gets empty I'll use first set.

I hope I described it better

you would need a bloody big roof about 4kwh solar panels

and about 12.5k

then you might just have enough power in this weather:rotfl:

Hi

What you are asking is can batteries deliver 2.5kWh of energy over (say) 10 hours and then be recharged by a 60W panel in the day (say 10 hours) ...... ignoring performance losses and irradiation completely, a simple question in it's basic form is ....

Does the following equation balance ?
250x10 = 60x10

.... I think you'll need a few more panels, some serious batteries and a shedload of cash if that's what you're trying to achieve ..

The rating of your small PV panels producing 1.8watts is measured under laboratory conditions. The will only get close to that power output around noon on a cloudless day in mid summer, for much of the year they will just produce a fraction of that power. So your theoretical 60 watts max panels might take several weeks to charge a set of batteries capable of delivering 5,000watt/hours(5kWh)

Back to the drawing board I am afraid!

You could just pay your share of the bills....

I don't want to pay 100$ per month. I think I'll create 500w power solar panel here in my area we only get one month of rainy and cloudy season. ONe more thing can I use a 500w solarpanel to charge and use at the same time? how much power does battery need to charge and can I use my fan, laptop or other appliances at the same time?

Sorry but you are wasting your time even thinking of power your appliances by batteries. Apart from the £thousands the system will cost, you can't keep battery banks of that size in a house - they are potentially lethal and need a special battery room.

Buy a 1kW portable generator and have it running outside your flatmates window!

Hi

Where will you place your ~4sqm (500W) of panels .... bet that's bigger than your window ..... I've got some old amorphous panels charging some batteries and 500W would cover about 14sqm ....

Anyway, a 4kWp professional system probably averages around 15kWh per day in the summer and in the winter this drops to around 5kWh/day ..... add in battery and inverter losses you'd be lucky to average 9kWh and 3kWh respectively .... so get around 60sqm of panels (6kWp) and around 1 tonne of batteries in your room and you might, yes might !, just about be able to do what you need to do .... most days, not all ! ....

Building the panels yourself will not be cheap either ... you'll probably need to allow somewhere around £50/sqm for glass alone, so thats £3k .... so 30 months of £100/month, simple deep cycle leisure batteries would be a couple of thousand, so another 20 months, we're over 4 years now ... I take it that this isn't an idea to save money at university, so lets look at some kind of aluminium frame for the panels .... I suppose that you could get hold of profiles for around another £2k to £3k (if you're lucky) .... then there's the charge controller and the inverter and the mounting and the cabling and the cells ..... don't forget the fire damage either ..... getting closer yet ? .... if you're starting university now you'll be 30 by the time you've finished building the panels and probably retired before they've saved the £100/month whilst studying .....

hahahaha got it. I'll try to get my own electricity meter.

Thanks all of you.
