You may be interested in solar energy, and would like to install a 4-kw solar system at your home. The average American home uses 30 kWh per day of electricity, which is approximately 11,000 kWh each year. This article will explain what a typical output of a 4kw system, and how to estimate its size based on your energy consumption.
4kw is the average output of a solar panel array system
An average four-kilowatt sunroof system can generate between 11 kWh and 18 kWh each day. But, this number can change depending on many factors such as the location of your system and the weather conditions. You should therefore consider where you want your solar panel system to be most effective. A solar panel system requires that your roof be angled so that the sun reaches it from the best angle.
The average output of a 4-kilowatt-sized solar panel system will differ depending on the weather conditions and the amount sunlight in your area. The more sunlight your panels receive, the more energy they will produce. A typical four-kilowatt solar system can produce approximately 2,850 kWh per year. This is enough electricity to power a typical home with two bedrooms.
Average cost of 4kw solar panels
A 4 kW solar panel system costs about PS18,000. You should place the solar panel system on a roof that gets a good amount of sunlight to get the best results. It doesn't have to face south, but it must have good exposure throughout the day. It can generate significant amounts of energy even if it is only exposed to sunlight for two hours. However, the more the sun shines the better. You should also remember that solar power can be used at home.
A 4,000 watt solar panel system can easily offset a $100 electric bill each month. It's important to note that this savings may vary depending on your utility company and location. You can save up to PS6,000 if you plan on installing a home system. As utility rates rise at about 4% per year, the savings can be substantial.
4kw Solar Panel System: Average Return on Investment
The average return-on-investment (ROI), for a 4kW solar array system is about 20%. Two factors affect the rate of return: the system's output, and the energy consumption of the house's users. For self-installed, the ROI is approximately 6.5%, while contractor-installed, it is approximately 10.5%.
You should include the cost for batteries in your return-on-investment calculation. Like panels, batteries can degrade over time. In some cases, 50% or more of the original output can be lost. This is to be expected. This is why you should look for systems with power optimizers and micro-inverters. These systems cost more up front, but the extra production over time will more than make up for it.
Estimating the size of a 4kw solar panel system
There are several factors that you should consider when estimating the size and cost of a solar electric power system. The first is how much energy you use each month in your home or business. This information is found on your monthly power bill. In some cases, the utility company will provide you with a summary chart of your average daily usage over the last year. This information will allow you to calculate the size of your solar panels system.
Next, think about the space available. A large solar array produces more electricity than a tiny one. However, larger panels are more expensive. They produce more energy per square meter.
