15kw solar system
15kW solar system
A 15kW solar system is ideal for homes, farms and small businesses.
A15kW solar system belongs to 48V family energy storage series. This high-quality solar system provides reliable power, without any compromise on your lifestyle. Capabilities of this off-grid solar system can power a medium sized house and larger properties.
The complete off-grid 15kW solar power system is the most versatile and popular of our off-grid stand-alone solar system products.
1: Your Access to Electricity
With an off-grid solar system, you’re completely reliant on the sun and energy stored in batteries to power your home or business.If you decide to install an on-grid solar system, you will always have access to electricity from the utility grid whether or not your solar system is producing energy.
2: What Happens When the Grids Goes Down
With an off-grid solar system, your solar system is working independently from the power grid and it can continue operating. If you have a grid-tied solar system and the grid goes down, you will not have electricity, unless you opt for a grid-tied solar system with battery backup.
3: How You Are Billed for Electricity
If your system is not tied to a grid, you won’t receive an electric bill. However, off-grid systems are often more expensive because of the additional equipment like batteries needed. If you opt for a grid-tied system, you could still see delivery charges or demand charges on your electricity bill, even if your solar system provides 100% of your electricity.
4: Is A 15kW Solar System Suitable for My Home?
The solar industry offers any array of solar systems, with each differing in the amount of power they generate. If you’re considering a solar system, think about the size of your household. What are your average energy expenses per month? If you have a large number of electrical appliances in use , additional battery storage is required.
With the characteristics of safety, long service life, and perfect after-sales service, a 15kW solar system is the best choice for sizable households or small-scale businesses.
A 15kW solar system is with enough power to suit large households’ needs because it can produce up to 5kW per day in the battery type of lithium iron phosphate. It may require 3 parallel batteries due to their ability to export more than 5kW at one time. As a 15kW system can produce more power, it is more expensive than the smaller ones. However, if you have higher energy requirements, it’s often quicker to pay off the cost of installation by installing a system with a larger capacity..
If you live in a household of more than 8 people, a 15kW solar power system is likely to meet your requirements.
5: How Much Does A 15kW Solar System Cost?
The below table shows average solar panel of per kW costs of some countries.
Therefore, the rough cost of a 15kW solar system in Germany should be—$1,113*15=$16,695.
Likewise, the rough cost of a 15kW solar system in France should be—$1074*15=$16,110.
The cost of solar panels depends on many factors, including their quality, model types, and the like. A system of larger size can generate more electricity, but it’s relatively expensive. Although it may not feel cost-effective at first, solar power can offer quick returns on your investment and help you build a more sustainable future.
The ultimate cost of getting a solar panel system installed will depend on the following factors: quality of solar panels; size of solar panels etc..
6：What is the Payback Period for a 15kW Solar System?
This figure depends on where you live, your cost of electricity, your feed-in tariff, and your daily energy usage. To determine how long it would take to pay off a system, you must calculate the total monetary value of the energy produced by the system on an annual basis, and divide the cost of the system by this figure.
You can do this by figuring out what the cost of power is, how much you will export and use in the home, and what your daily savings are.
7: How Long Will a 15kW Solar System Last?
Like most solar systems, the average life span of a 15kW system is 25 to 30 years. According to the National Renewable Energy Laboratory, solar panels face an average efficiency drop of 0.8% each year. This performance decline is called the solar degradation rate, and it varies among manufacturers. For instance, some solar industry brand may claim a degradation rate as low as 0.3%, while other substandard solar systems could devalue much faster.
What is the solar degradation rate? Simply put, panels become less efficient when producing electricity over time and their solar system output will also decrease. This process is called degradation, and it can take up to 30 years for a high-quality solar system to suffer its effects.
However, despite several decades of use, panels don’t lose their value. Rather, their energy output decreases slightly below the solar company specifications. Light & Elevated Temperature Degradation (LetiD) is the name given to this phenomenon. Better quality panels will last longer and resist this degradation.
Solar panels are incredibly sturdy and are able to last decades with little maintenance. They are designed to withstand strong winds and hail storms, so having your system demolished due to weather conditions is hardly likely. Still, you can ensure more power over the years via the following methods: regularly maintenance; regular dust and debris clearing out.
- Modular design;
- Standardized production;
- Strong commonality;
- Easy installation, operation and maintenance;
- Perfect BMS protection and control system for over current, over voltage, insulation and the like;
- Utilization of lithium iron phosphate cell with low internal resistance and high rate;
- High consistency of internal resistance, voltage and capacity of single cell;
- A long life cycle of around 5,000 times; a service life of more than 10 years;
- Fast charging and discharging support;
- Visual LCD display: allows you to set operating parameters, view real-time data and operating status, and accurately diagnose operating faults.
- Communication protocol: CAN2.0 and RS485, which can be used in various scenarios.
