DIY Solar Project Checklist

This checklist will walk you through every step needed to design and install your own solar power system—from planning and sourcing to installation and maintenance. Whether you’re going fully off-grid or just want backup power, this guide has you covered.

Define your daily energy needs: Use our solar build guide to calculate watt-hours and plan capacity.
Check local regulations: Research zoning laws, permit requirements, and HOA limitations.
Choose a system type: Grid-tied, off-grid, or hybrid based on your goals and budget.
Calculate panel requirements: Determine wattage needed, sun hours, and how many panels you need.
Select key components: Panels, batteries, inverters, and charge controllers. See our battery comparison.
Gather hardware: Mounts, wiring, fuses, connectors, and grounding materials.
Pick a location: Choose an area with full sunlight and minimal shading throughout the day.
Install mounting hardware: Ensure the structure is secure and weather-resistant.
Mount panels: Install at the optimal tilt and orientation for your location.
Wire the system: Connect panels to the inverter, include DC/AC disconnects and safety fusing.
Install a charge controller: Required for setups with batteries to regulate voltage and protect cells.
Connect the battery bank: Use proper ventilation, spacing, and a reliable BMS. See how here.
Set up system monitoring: Use an app or gauge to track charge levels and solar output.
Power up and test: Measure voltage, load, and consistency before going live.
Plan routine maintenance: Clean panels and inspect wiring every 3–6 months.
