In short no. 20 of them maybe. The average water heaters electrical element is 800-1200 Watts and they usually have 2. If you have an electric water heater read the spec sticker on the side and it should tell you the electrical specs are, probably 220v 5-6amp or more so at 5 amp you'd be looking at 220x5=1100watts, at 6 amps; 220x6=1320watts. Just do the math and figure it out.
You can size your solar array in just two easy steps! (Well, okay, there's a little research involved, too.) To estimate the size of your solar array, you'll need to know: # The number of Watt-hours (Wh) you plan to produce in one day. # The insolation value at your location. I have found this website to offer the easiest way to find out How Many Solar Panels do you need in your Solar Array?http://howto.altestore.com/Library-Articles/Solar-Electric-Power-or-PV-Systems/How-Many-Solar-Panels-do-you-need-in-your-Solar-Array/a88/
5000w/190w=26.316 so connect atleast 27 solar panels.
#6 wire is needed. If placing the subpanel in a garage at a good distance, it is recommended to also install a seperate ground rod .
MW is a unit of power just like kW 1MW = 1000 kW 1 mega-watt = 1000 kilo-watt Watt is a measurement of power. watt-hour is a unit of energy 1 mega-watt-hour = 1000 kilo-watt-hour
It will power two 400 watt lamps.
can a 500 watt solar panel run a 500 watt appliance with 2 102 amp deep cycle batteries
About 200 Dollars
only if u use a battery to boost power ,
A few variables are involved like, does the solar panel have a charge controller, what condition the battery is before you start and how much sun is the solar panel receiving.
One 25w solar panel for one 100w bulb. A 100-watt solar panel can produce about 400 watthours of power per day. A typical home consumes about 25,000 watthours per day. So you would need 62 one-hundred watt solar panels to run an average home.
200 Watt Panel
4 Watt-hours
1 watt will do the job.
The average solar panel cost about $3.00 a watt wholesale. It delivers about $0.0015 per day. The projected life is about 20 years if the weather is not too hot.
None, since one does not normally "power" a solar panel. However a single 7w lamp would be useable with a 5watt panel but with reduced efficiency unless the panel was used to charge a battery first and then the bulb was powered by the battery.
A 20 watt solar panel produces 20 watts of power/hour when it is in direct sunlight. However, this varies depending on the conditions. It won't produce at 100% in cloudy conditions. Let's say the 20 watt panel gets about 5 hours of good sunlight everyday between 10am and 3pm. This will produce .1 kWh or 100 watt hours. This means you can run a 100 watt bulb for one hour or two 50 watt bulbs for one hour.http://www.heatingandcoolingcompanies.org/
Solar panels are ridiculously expensive. A small 130 watt unit costs almost $600. To run your house on solar panels you are looking at thousands of dollars.
