40kw 35kw 45kw Solar Energy System Specification
The 40kw 35kw 45kw solar power system is composed of solar panels, solar inverters, lithium batteries, photovoltaic mounts and other accessories. It can provide a constant supply of electricity for commercial and industrial power places, especially in some areas with high electricity costs or frequent power outages it plays an important role.
The system has three design options: grid-connected, off-grid and hybrid. If the budget is not very large and the electricity is seldom used at night, then the grid-connected system can be considered.
40kw Solar Power System Price
The price of a 40kw solar system is from $700 to $22000, 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 40kWh, 80kWh, 100kWh or even larger capacity batteries.

40kw solar system power generation per day
A 40kw solar panel can generate approximately 130kWh to 220kWh of electricity per day. The amount of power generated depends on the latitude and altitude of the installation location, as well as the ambient temperature. In addition, we need to calculate the optimal inclination of the PV panels according to the latitude and keep the panels clean. This will maximize the amount of power generated.
Selection of inverter for 40kw solar system
If you need batteries then you need to choose a 40kw off grid solar inverter or hybrid inverter. If you don’t need batteries then you can choose a grid inverter, which is cheaper and has a higher conversion rate. In addition, 40kw solar inverter is usually a three-phase output.
40kw solar system Battery selection
We recommend a high voltage battery with a capacity of 50kWh to 100kWh. This can vary depending on how long the main load is working at night. If the loads are all working during the day and the city grid is stable, then you can choose not to have batteries.
How much money can I save with a 40kw solar system?
A 40kw solar kit can save about $8,000 per year on your electricity bill. The investment will pay for itself in 3 to 5 years, and will pay for itself for the next 30 years or more. This is a very cost-effective investment.
How long does a 40kw solar system last?
A 40kw solar system can last for more than 30 years, but the batteries and inverter may need to be replaced or repaired in about 10 years. PV mounts and wiring hardly ever need to be replaced.
What can a 40kw solar system run?
A 40kw photovoltaic system can power large installations, it can handle loads up to 40kw and can start inductive loads of around 20kw with motors at the same time. It can accommodate commercial and industrial equipment.
