18kw 19kw solar energy system specification
The 18kw solar power system can generate between 60kWh and 100kWh of electricity per day. This power generation capacity can already satisfy many small power consumption places, such as, hospitals, schools, small factories and so on. If more power is used at night, then more batteries are needed as backup power.
The system can output up to 20kw of power and can work for 12HP loads with motors. And there are three kinds of systems for you to choose: on grid, off-grid and hybrid.
18kw on grid system: without batteries, the electricity generated by the solar is used for the load and the excess electricity is fed back into the grid company.
18kw off grid system: with battery, both solar and utility can be used for loads, the battery is used as a back-up power source to provide electricity to the loads at night and on cloudy and rainy days.
18kw hybrid system: it combines the functions and advantages of both on grid and off grid, maximizing the use of the electricity generated by the solar, but at a slightly higher price.
18kw Solar Power System Price
The price of a 18kw solar system is from $4000 to $9200, It depends on which option you choose, if it’s a on grid system without batteries the cost is much lower. If you need batteries as a back-up then off-grid and hybrid are great options with 20kWh, 30kWh, 40kWh or even larger capacity batteries.

|---|---|
| 18kw on grid solar system | Around 4000USD |
| 18kw off grid solar system | Around 8000USD |
| 18kw hybrid solar system | Around 9200USD |

18kw solar system size
The size of an 18kw solar panel is approximately 85m². However, it is important to consider that each row of solar arrays needs to have sufficient space and access for operation and maintenance. So for a pitched roof, an installation area of about 90m² is required. For a level ground or roof it would be about 120m².
Selection of battery capacity for 18kw solar system
For grid-tied systems, no batteries are required. For off-grid or hybrid systems, we recommend a battery capacity of 20kWh to 60kWh lithium battery. For lead acid batteries, the solar battery capacity required is around 40kWh to 100kWh. The amount of battery capacity depends on the amount of electricity consumed by the main load during the night.
How much money can I save by installing an 18kw solar system?
Installing an 18kw solar system can save approximately $4000 per year on your electricity bill. The exact figure will depend on the local electricity prices and the amount of PV power generated. In addition, in many countries there are government incentives such as one-time subsidies and excise tax credits for installing PV systems. Check with your local grid company for details.
What are the factors that affect the amount of electricity generated by an 18kw solar system?
Seasonal variations, changes in ambient temperature, tilt angle of the solar panels, latitude and altitude of the PV installation are all important factors that affect the amount of electricity generated by the PV system. Also keeping the PV panels clean will help increase the amount of power generated by the PV panels.
What can an 18kw solar system run?
An 18kw solar kit can meet the electricity needs of a total load of up to 18kw. If the load is an inductive load containing a motor, no more than 10kw can be started at the same time.
