What do I need to complete my off-grid solar power system ?

You need a solar panel, a charge controller to regulate current, and a deep-cycle battery for storage. For wiring, you will need adapter kit cables (panel to controller) and tray cables (controller to battery) to complete the system.

What does off-grid and on-grid mean ?

On-grid means connected to the power grid. Off-grid means independent of the grid, storing power in batteries for later use, so you are never affected by grid blackouts.

Why is my solar panel under producing ?

Solar panel performance may be hindered for a number of reasons. Most commonly environmental conditions such as indirect sunlight, temperature rise, cloudy sky, and dirt and stain build up on the top glass will cause a reduced power output.

How should I connect solar panels in my electrical circuit (series vs parallel)

Connect in series to increase total voltage (current stays the same), or in parallel to increase total current (voltage stays the same). Combine both for optimum system power output.

How many solar panels do I need ?

First, determine your total power load (Watts × run hours × 1.5-2 safety factor). Size your battery bank based on this capacity, and accordingly decide how many panels or how much power input is needed.
