Solar System Kits
Solar power systems vary in use and size, solar panel kits are available in different types of bundles to take into account various factors. You can get hybrid wind and solar systems as well. Most solar panel kits include the basic components to make panel installation a breeze. Solar System Kits typically include:
Solar Panels
Battery bank
Power inverter or charge controller
Cables
Mounting Hardware
Here are some kits for you to purchase for an easy set up off grid. These systems can be used as a stand alone system not grid tied.
Batteries for off grid systems
The amount of battery storage you need is based on your energy usage. Energy usage is measured in kilowatt hours over a period of time.
For example:
1,000 watts x 10 hours per day = 10 kWh per day
Other factors influence battery sizing:
Ambient Temperature - Heat or cold has a big impact on battery performance and capacity.
Seasonal Factors - People use more power at different times of the year. The sun produces more power in the summer than in the winter.
Budget - Battery bank size is often a compromise between what you want to spend on batteries and how often you'll need to run your backup generator.
Battery Size Information
Lead Acid Sizing
10kWh x 2 (for 50% depth of discharge) x 1.2 (inefficiency factor) = 24 kWh Lithium Sizing
10kWh x 1.2 (for 80% depth of discharge) x 1.05 (inefficiency factor) = 12.6 kWh
Battery capacity is specified either in kilowatt hours, or amp hours.
For example, 24 kWh = 500 amp hours at 48 volts → 500 Ah x 48V = 24 kWh
Battery banks are typically wired for either 12 volts, 24 volts or 48 volts depending on the size of the system
Examples for Lead Acid and Lithium:
For Lead Acid, 24kWh is equal to:
2,000 amp hours at 12 volts
1,000 amp hours at 24 volts
500 amp hours at 48 volts
For Lithium, 12.6 kWh is equal to:
1,050 amp hours at 12 volts
525 amp hours at 24 volts
262.5 amp hours at 48 volts

Charge Controllers and Wiring Supplies
Wiring your electrical run is a critical part of any solar installation, and the specifics differ based on the kind of system you’re installing.
Helpful Tips and Advice
Plan the wiring run in advance so the wires don’t interfere with access to the array.
Use wire clips to secure the factory wire leads in place so they don’t move in the wind or touch the roof Wire clips allow you to run the wires along the rails or the frame of the solar panel.
Many solar components use spring clamps, which require you to push down on a metal bar (or another mechanism) to open the terminal so you can seat the wire. Once the wire is firmly seated, release the spring, which clamps the wire in place.
