Off Grid 5.4kW Solar Power System

Let altE help you with your off grid system and make it easy to decide which one is best for you!
  1. First, you need to decide what your daily power needs are. This will help determine which size system is appropriate for you. If you need help sizing a system for your off grid home, start by checking out our Off Grid System Calculator.
  2. Next, find where you live on the map below. This will show you he amount of daily power, in hours, received each day, on an optimally tilted surface during the time of year when there's the least amount of sun.
  3. Then, what type of energy storage is best for your needs? Do you like low maintenance, lowest cost option, longest cycle life? See the Battery Option chart below to help you decide.
  4. Lastly - how do you want to mount your system? Is your roof in good shape, free from tree/building shadows, and south facing? Or do you have enough open land to do a ground mount or pole mount system? What's your climate where you live- do you have heavy snow loads?

How much power will I get from this system?

5.4kW Insolation Map

  • So if you lived in the Northesast for example, at 8.1 kWh of daily power, you'd get on average 243 kWh of power each month
  • If you lived in Florida, at 14.5kWh of daily power, you'd get on average 435 kWh of power each month
  • Southwest areas of the country, at 17.8kWh of daily power, can get on average 534 kWh of power each month

  • Base Components of this Off Grid System:

    The solar panels and the pre-wired inverter/charge controller system and components are included in the base kit. Battery bank and Mounting solutions are options that you can add on.
