Base Kit 2 Off-Grid 4.88kW Residential Solar Power System
|Item code||Model number|
|KITOFFGRIDBASE2||Off-Grid 4.88kW System|
Off Grid 4.88kW Solar Power SystemLet altE help you with your off grid system and make it easy to decide which one is best for you!
- 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.
- 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.
- 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.
- 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?
