Planning to Go Solar: What to Know Before You Install Your Panels

how are solar panels installed step by step process guide

Before embarking on the solar installation journey, gain a solid understanding of your electricity usage by analyzing your electric bill. This will help determine the appropriate system size and anticipated savings. Investigating local, state, and federal incentives, as well as solar rebates, can significantly reduce overall costs. Researching net metering policies, where available, is also advisable as it can lead to credits on your bill for surplus energy provided back to the grid. Consulting with a solar professional can offer tailored insights, ensuring that you make informed decisions aligned with your energy needs and financial goals.

Understand Your Electric Bill

Before embarking on the installation process, it is essential to take a closer look at your electricity consumption as reflected on your utility bill. Your bill provides key insights that help in designing an efficient solar system:

  • Monthly energy usage: Measured in kilowatt-hours (kWh), this figure indicates the scale of solar installation needed.
  • Peak demand: Identify when you use the most electricity to ensure your system meets these demands.
  • Rate structure: Understand whether you’re on a flat rate, time-of-use, or tiered rate to maximize savings.
  • Net metering availability: Determine if your utility offers net metering, allowing you to sell excess generation back to the grid, thus impacting your payback period.

Explore Incentives and Rebates

Solar investments often qualify for governmental incentives that significantly offset initial costs. The federal solar tax credit, also known as the investment tax credit (ITC), allows you to deduct a percentage of the solar system’s cost from your federal taxes. This credit is available for both residential and commercial installations.

Additionally, many states offer their own tax credits, rebates, and Solar Renewable Energy Credits (SRECs), which let you sell generated electricity back to the grid.

Check for specific local incentives which can further reduce installation costs. Utilities may have programs offering rebates for each watt of solar power installed. Researching community solar programs can yield benefits if on-site installation isn’t viable. Nonprofit organizations sometimes provide discounts for solar installations through group purchase programs.

For the most current information, consult the Database of State Incentives for Renewables & Efficiency (DSIRE), an up-to-date resource listing incentives and policies supporting renewables in the U.S. Engage with local solar installers who can navigate these incentives and ensure maximum savings.


Once the solar project is adequately planned, the physical installation can commence. This begins with setting up the racking system, which is the foundation that holds the solar panels in place. The racking system is securely anchored to the roof or ground and must be angled correctly to optimize solar exposure.

Next, solar panels are mounted onto the racking system. Each panel is positioned and fastened to withstand environmental factors such as wind and snow. Panels are interconnected in series or parallel to match the system’s design specifications.

The final step in the installation process is the electrical integration. Solar panels are connected to an inverter, which converts the direct current (DC) electricity generated by the panels into alternating current (AC) electricity that can be used by the home or business. The inverter is then connected to the existing electrical panel, integrating the solar system with the building’s power supply. Proper grounding and protection against electrical surges are necessary to ensure safety and compliance with electrical codes.

After these installation steps are completed, an inspection is commonly required before the system can be connected to the grid.

Plan Your Project

Selecting the suitable location and arrangement for your solar panel installation is crucial. The area must receive optimal sunlight, generally a south-facing roof in the Northern Hemisphere. Geographic location, roof condition, shading, and local climate also significantly impact your project planning. Engaging a licensed solar assessor can determine the most efficient configuration for your needs.

Determining system size is driven by energy consumption patterns and goals for solar coverage. Panels come in various wattages, and your system’s total wattage will influence the number of panels needed.

Local building codes, permits, and regulations must be adhered to. Providers often manage permitting, but homeowners should be informed about the process. Additionally, you should consult with your homeowners association if applicable, as there may be restrictions on solar panel installations.

A professional engineering site visit is standard. The visit assesses your home’s electrical status, roof integrity, and ensures compatibility with solar equipment.

Establishing a timeline for the installation process is also essential. Typical solar installations can take anywhere from one to three days once on-site work begins, depending on system size and complexity. However, the entire process from assessment to activation can span several weeks to months due to planning, permits, and utility company approvals.
