With the advancement of technology, more and more electrical appliances are starting to make their way into people’s lives. At the same time, electricity bills continue to grow and some people are tired of the rising electricity bills and decide to power themselves using their own methods. They decided to install solar power systems and the 8kw solar power systems are becoming popular among more and more people. People are installing solar power systems of this size to power themselves.
We all have different geographical locations and energy needs, so is an 8kw solar power system right for us? Read the following to help you out.
Cost of an 8kw solar power system
In fact, the cost price of installing an 8kw solar power system (including solar battery) is between $4,000 and $5,000. If you don’t include the solar battery, the cost price is between $2,000 and $3,000. This price does not include shipping and customs. If you add shipping and duties, the price could be several times higher.
This price may be more than you expected, but don’t worry, the world is supportive of installing solar power systems, and governments around the world have policies in place to encourage the installation of solar power systems.
In the United States there are incentives such as federal solar tax credits, and there are incentives in other regions as well. With the help of these policies, the cost will drop by about 30%.
Of course if you just can’t afford this, you can apply for a solar loan. Due to the interest rates as well as dealer fees, you will have to pay more money for a solar power system through a loan than if you buy it in cash.
How many solar panels do you need for an 8kw solar power system and the footprint?
How many solar panels you need for an 8kw solar power system depends on the power of the solar panels. The common solar panels used nowadays are between 300w and 700w. If a 400w solar panel is used, then 20 pieces will be needed. If 300w solar panels are used, then 28 solar panels will be required
To install a solar power system, its footprint is also an important factor to consider. Solar panels mounted on a sloping roof have a smaller footprint than those mounted on a horizontal roof or on the ground when the total power is comparable.
A solar panel mounted on a tilted roof requires approximately 38 square meters of floor space, while a solar panel mounted on a horizontal roof or on the ground requires approximately 53 square meters of floor space.
Does an 8kw solar power system produce enough electricity to power a home?
An 8kw solar power system can produce between 800 kWh and 1400 kWh of electricity per month. The exact number only depends on the amount of light your roof can get each month. And big data shows that a normal household uses around 800 kWh of electricity per month, which means that as long as you don’t have any very power-hungry non-domestic appliances in your home, then an 8kw solar power system is more than enough to power your home.
How long does it take to pay back the cost of installing an 8kw solar power system?
Normally, the amount of money you can earn each month from a solar power system depends largely on the amount of electricity you generate each month. Every 1 kWh of electricity you generate means 1 kWh less to pay for, and if you don’t use up all the electricity you generate each month, you can also store the excess for the next month or sell it to the grid company.
You can get a good return in the above ways. According to the relevant data, it can be seen that it costs about $0.11 per kilowatt hour of electricity when you don’t have a solar power system installed, and only about $0.04 per kilowatt hour of electricity when you have a solar power system installed. It will pay for itself in 5 years. Of course in areas where the weather is sunny, suitable for solar panels to work and where electricity is expensive, you can save even more on your electricity bill every month.
Can you try to install an 8kw solar power system yourself?
If you have learned about electricity on your own and the type of solar power system you are installing is an off-grid system, then you can try to install it on your own. But if you haven’t learned about electricity, you’d better let a professional installer do the job for your safety.
If you are installing a solar power system that is grid-tied, there are some insignificant installations that you can take care of yourself. But if it is the work of integrating the solar power system into the grid, you must let a professional installer do the work, and the work of integrating into the grid needs a special license to be carried out. If you carry out the relevant work on your own, it is illegal.
Conclusion
There is no doubt that an 8kw solar power system is more than enough to power most homes. As long as you don’t have a lot of high-power consuming appliances in your home and you live in a place that gets plenty of light, then installing this solar power system basically means that you’re off the grid.
