20kw solar system

The below table shows average solar panel of per kW costs of some countries.

Therefore, the rough cost of 8 kW solar system in Germany should be —$1113*8=$8904.

Likewise, the rough cost of 8 kW solar system in France should be—$1074*8=$8592.

There are four important factors that influence the cost of solar panels.

• Wholesale equipment costs:As a young industry, factories have been able to automate processes, increase manufacturing and logistics scale and dramatically reduce the cost per watt of a solar installation.
• compensation: In order to encourage households to select solar energy, government implements intriguing policies to attract citizens to select solar energy, such as The Solar Rebates. The introduction of local solar rebate schemes in particular states has had a dramatic effect on the cost of solar
• Competition and Cheap Solar: there are thousands of contractors to install solar. As a result, the margins have been forced to be very slim in the market.

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.

A 20kW solar system is certainly powerful enough to cater to the average electrical needs of a 8-to-10 person household.

However, power compatibility depends on:

• Utilities and home appliances that consume energy and therefore determine the maximum power usage in your household.
• Your lifestyle. If you work at home, you’ll consume power all day, unlike a job where you can turn off the power supply until you return from work.
•  Electrical vehicles you own. If you have a Tesla or plan to buy one, a 20kW solar system won’t be enough to power both the car and your household.
• Your average daily energy usage during summer and winter.

Your solar system power compatibility depends on the above-listed factors and how these align to installation in your area.

To understand if a 20kW system can power your home, you’ll divide your average daily usage by the local peak sun hour. You can find your average daily use on your electricity bill.

Average daily usage (kWh) / the local peak sun hour=Your recommended solar system size. Once again this is because a system will produce the times of the local peak sun hour its size in power per day.

If the kilowatt per hour displayed on your home electricity bill shows you consume 35 kWh per day, and the peak sun hour is 4 hours, a 20kW solar system will be enough. Anything higher than 20 kWh usage per day implies it won’t be sufficient.

A few things to consider before going solar are available space, energy needs, cost, and your overall aims for solar system installation.

A smaller system will produce less electricity than a larger system. If you’re a two-person household with low energy consumption, a smaller 5kW system will be plenty for daily use. If not, a system that will generate extra power is more advisable. 

The cost is also an important factor. Since larger solar systems will cost more than smaller solar systems,   payback period is affected.

• 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.
