What Size Solar Panels Do You Need?

Solar panels come in different sizes. And when it comes to sizes, usually we refer to the wattage of a panel can produce, or physical size. Both are linked because the watt panel can produce, the bigger.

Decide on the size of your solar system depends on two factors: the amount of electricity used his house, and the money they are willing to invest in the solar system. Solar systems can be very expensive, and even if they pay for themselves over time, buying all panels to power an entire house can be financially out of reach for many families.

The average size of a solar system

Just to give an idea, an average solar panel can produce about 150w. 150w a group of about 1 square foot size. So you should always keep in mind is the fact that the panel can produce as much energy as perfect on sunny days, when the sun falls directly on it. Therefore, the panel will produce 150 watts only 3-4 hours a day (when the sun is brighter) depending on the isolation of the area where you live.

The size of a solar system is calculated in kWp, an abbreviation for kilowatt peak. A 1.5 kWp system can generate 1500 watts of sunshine. This system consists of 10 solar panels 150w and each occupies 10 square feet of roof space. 1500 Wp solar system can not provide all the energy needed for an average household, but it would do a decent job of providing it.

This is just an example and may not apply to you. Unfortunately, a typical house uses a lot of energy, and if you want to provide all the power with the help of a solar system, you would have to pay thousands of dollars on it. It would be best to find a compromise solution that alleviates at least some of the energy needs of your home.

If a solar system which gives all the energy needs of your home is too big, and you have or not have enough space or enough money to pay, there are some solutions you can try. One would be to reduce their energy consumption. You can also buy energy efficient appliances for your home. Another idea would be to buy solar panels one at a time, when you have money. Other financial solutions are also available, such as green tax rebates and incentives, so that would be a good idea to find out about those in force in your state.
