## Determining the Ideal Number of Solar Panels Your Home Needs

Homeowners opt for solar panels for various reasons. Well, the benefits of solar as an alternative source of energy cannot be overemphasized. As such, the issue of whether to invest in solar panels or not is no longer the question. What many homeowners find a little confusing is the number of solar panels that would effectively power their homes.

How many solar panels do I need? The answer depends on several factors for each individual family. For those who want to reduce the electricity bills, you must sit down and factor in the total kilowatts per hour needed. What is the average daily use of electricity in your home? You can have a deeper insight on your electricity bills to come up with right statistics.

How many kilowatts of electricity do you use in one year? If you check most monthly bills, there is detailed information regarding total power consumption over the last twelve months. Just to offer some insight, one kWh is a thousand watts of power used within an hour. According to a recent survey, the average American household uses 909 Kwh every month. In essence, an individual household consumes less than 11,000 kWh every year. That can provide a perfect base for calculating the ultimate number of solar panels you need.

Capture the daily peak sunlight hours

Solar panels are exclusively reliant on the sun to produce electricity. The number of solar panels you will need therefore depends on the peak sunlight exposure of your area. Which part of the country are you? Location aside, the time of the year also affects the amount of sunlight you will receive the entire year. For areas receiving less sunlight all year round, it might be necessary to install larger systems.

For purposes of calculations, you can get the right figures of your state from Renewable Resource Data Centre. With the daily energy requirement figures and number of daily peak sunlight hours, it is possible to calculate amount of energy your panel should pick up every hour. The figure will be critical in calculating the number of solar panels you need for your home.

The ideal number

Notably, solar panels are available in a variety of wattages. It is upon you to settle on 100W, 200W, 250W or any other model. The choice of wattage will determine the ideal number of solar panels for your home. To get the exact number, divide the hourly energy requirements by the wattage of the solar panel. For instance, a household that needs 3940 W will require 20 panels, each with 200-W rating to sustain the entire house.

With the right estimates of annual energy usage, you can easily determine the ideal size and number of solar panels your home requires. It is important to factor in common consumer products and add-ons. You can always take advantage of the suppliers to help you understand and make critical decisions on the same. Most importantly, carry out your research widely before making any commitment.
