About These Estimates
These are ballpark estimates based on typical 2024-2025 pricing for DIY solar equipment purchased online. Actual costs vary by brand, supplier, shipping, and local market conditions.
Budget tier uses economy panels and components — good for non-critical applications and learning builds. Mid-range represents popular brands like LiTime, Renogy, and EG4. Premium covers top-shelf gear like Battleborn, Victron, and high-efficiency panels.
The 30% Federal Investment Tax Credit (ITC) applies to the full cost of solar energy systems installed on your primary or secondary residence. This is a dollar-for-dollar tax credit, not a deduction. Consult a tax professional for eligibility specifics.
The professional install comparison uses an average of $3.00/watt, which is the typical all-in price for a residential solar installation in the US. This includes equipment, labor, permitting, and installer margin.
For a detailed breakdown of how the 30% ITC works and exactly what expenses qualify (including batteries, wiring, and permits), read our federal solar tax credit guide for 2026.
