What Components Make Up a Solar Energy System?
A solar energy system consists of several key components in addition to solar panels themselves.
To generate your own electricity, you need a complete solar power system, whose main components are as follows:
Solar panels: Capture solar energy.
Inverters: Convert this energy into a form that can power your electrical appliances.
Mounting racks: The base for installing the system.
You also need a way to store the energy produced by solar panels. If you have access to the power grid, no additional equipment is required—simply feed the generated energy into the grid for later use.
However, off-grid setups call for extra components:
Batteries: Store the energy you generate.
Charge controllers: Regulate the rate at which batteries are charged by solar energy.
All these components are connected by smaller parts such as wires, fuses and circuit breakers.
At the same time, we will ship the tool bags so that customers can install it directly.
What Size Solar Power System Do I Need?
The capacity of your solar system is determined by your electricity consumption, measured in kilowatt-hours (kWh). You can find this figure on your electricity bill or in your online account with the power supplier.
Choosing the right system size is a complex process, but fortunately, there are plenty of online tools to assist you.
For grid-tied systems
The fastest way to get an estimate is to use our solar calculator. Just enter your location and electricity consumption data, and we’ll take care of the rest. We’ll provide you with a target system size and recommend several kits that may meet your needs.
For off-grid systems
First, calculate your daily energy usage using a load assessment sheet, then use our off-grid solar calculator to determine the target system size.
