does anyone know how many solar panels it would take to power a 200 amp home ? also howmany deep cell 12v ?

Question

got 200 amp service would like to convert tell me what you know?

Answer 1

It depends on a number of factors including the solar panel specification and the amount of sunlight.

This link may help you with the calculations:

This kit (UK) provides around 55 amp-hours per day:

Answer 2

Sir:

Your question is not practical to answer as posed because:

1.) Locality not specified. Each area of the earth has a certain average quantity of daylight exposure per day throughout the year. That exposure varies from place to place. Solar panels produce energy by being exposed to that sunlight. So, some locations would require more panels and batteries than others.

2.) While your question suggested that your home or the home in question had a 200 Amp power panel, no discussion was presented relating to the power conservation plan you intended to use. For example: Use of 110 VAC light bulbs would be highly wasteful if your primary power source is 12 VDC or 24 VDC. Do you intend to change out all your lighting to DC?

3.) No mention was made of the steering system you intended to utilize for aiming the solar panel array at the sun. The presence or absence of a steering system for the solar panel array affect the quantity of panels required to do a certain job (produce "x" watt hours of energy). Solar panels produce their maximum energy output when "directly" exposed to a light source such as the sun. When angled away from "direct" the amount of power produced by the solar cells is significantly lowered. Of course, a similar reduction in power occurs on cloudy/overcast days, and in the darkness of night no power is produced at all.

4.) Finally in order to design a solar array for your residence, or any site, a true list of electrical requirements, load devices, and hours of expected usage per day must be provided to the system designer. There is no reason to provide solar generating equipment, storage batteries, and DC-AC Inverter devices to power a well pump for 24 hours a day, 7 days a week, 365 days per year, for example, if the well pump only operates on average 3 hours per day. How many other devices in this solar home function in a similar manner? the electric laundry washer and dryer equipment, for example, most likely does not operate 24 hours per day, 7 days a week. Correctly delivering this information to the designer can make huge differences in the amount of equipment required to provide adequate solar power for a given installation. Air Conditioning/heating machinery consumes large amounts of electrical power, but that power varies with the time of year and normal occupancy of the residence. Maybe this residence is a vacation home which is unoccupied three fourths of the year. Refrigeration equipment draws current based upon the size of the Refrigerator/Freezer unit installed. What size unit will you have. Is that size adequate for your needs, to small, or really bigger than you need? Is there a more energy efficient model available? Are there any heavy duty mororized equipment units in your home or garage shop such as drill presses, band saws, table saws, air compressors, lathes, planers, and sanders? What is the expected usage of that equipment and what amount of power do they require? How many people will live for how many hours per day within this residence? Lighting requirements differ for a single employed person and a family of four (wife at home with children).

In conclusion, a true answer to your question is not easily rendered. The answer varies with location, devices to be served, and average occupancy.
