assuming you are going to choose standard-efficiency solar panels, here are the most common sizes for residential solar systems and their kwh production potential to give you an idea of how many panels you would need to run a house. a 3kw solar system which consists of 12 panels can produce an average of 4,200 kwh per year. you will need a roof space of about 194 sq ft for a 3kw system. a 5kw solar system which consists of 20 panels can produce an average of 7,000 kwh per year. you will need
if you go for on grid solar power plant, then the cost is rs 3 lakh rs 60,000 per kw in this solar power plant, you can also export the surplus/unused elecricity to the utility grid through the netmeter. if you go for off grid solar power plant, the cost will be rs 3.75 lakh rs 75,000 per kw .
solar panels have dropped in price considerably over the years. seven years ago, the general cost of a 50-watt panel was $215, or $4.30 a watt. nowadays, a 50-watt panel will run you $75, or $1.50 a watt. but the panels themselves are the most inexpensive part.
in this case, it would be about 37kwh per day. to keep things simple for this rough estimate, well assume that a 250w solar panel will produce about 1kwh a day. assuming that you use about 37 kwh per day, you would need about 37 solar panels to meet 100% of your average energy needs.
