The Cost for solar panel Installations on an Average United States House

You’ll have to correct guidelines respectively because they practice to an ordinary home with common consumption and average electricity costs. a rule of thumb is that the common house occupies electricity at the scale of 1 kW per hour (kWh). There are roughly 730 hours every month, and the common price of a kWh of electricity is $0.10. So a common monthly bill would be around $73 for 730 kWh of electricity.

Of course, this can vary considerably if you have non-standard items such as a hot tub, or some electrical appliances running continuously. Extended computer use, plasma screen TVs, and video games consoles can also make an impact. Your usage will increase significantly in months when you run an air conditioning unit, as well. Finally, the cost of electricity varies widely across the USA, from as low as $0.07/kWh in West Virginia to as much as $0.24/kWh in Hawaii.

A traditional value of a solar panel installation 

A traditional value to use as a solar panel’s producing ability is 10 watts/sq. ft. This serves a panel transformation performance of about 12%, which is common. This means that for every kW you generate, you need about 100 sq. ft. of solar panels. If the sun shone 24 hours a day, you could put up 100 sq. ft. of panels and have enough energy to power the average home.
But, as we all know, the sun is available only during daylight hours, and the amount available per day is highly dependent on the extent of cloud cover. Also, the length of each day is dependent on the season. Fortunately, there are resources on the web to help you figure out how many hours per day (on average) you can count on the sun to shine, based on where you live.

Standards beyond the USA for solar panel installation

You’ll need more panels if you live in a location that gets less sunshine per day, and fewer if you live in a location that gets more. The standards beyond the USA range from around 3 hours per day in areas like Seattle, Chicago, and Pittsburgh, to 5 or 6 hours per day in states like Colorado and California, to a high of 7 hours per day in Arizona. What that means is that the size of the panel array required can vary, anywhere from 400 sq. ft. to 800 sq. ft. (i.e., 4 kW to 8 kW), depending on where you live.

A grid-tied system like this is different than off-grid systems used in remote locations with no electrical service; those require batteries, which can significantly increase overall system costs. If your utility company allows you to have net metering — that is, they supply you with a special meter that will spin backward when you generate more electricity than you use — your annual bill can average out at zero. Because of shorter days in the winter, you’ll likely be a net purchaser of electricity in that season and a net producer in the summer months.

There has never been a better time to install a solar energy system!
