Going Solar Is a Process — Here Is Every Step in Order
The decision to go solar is straightforward. The process of actually doing it involves more steps than most homeowners expect — and skipping or rushing any of them leads to overpaying, choosing the wrong system, or dealing with installer problems down the road. This guide walks you through every step from initial research to the day your system turns on, in the correct order.
Step 1: Understand Your Energy Usage
Before you talk to a single installer, pull the last 12 months of electric bills and find your annual kilowatt-hour (kWh) consumption. This single number drives every other decision — system size, number of panels, battery storage needs, and projected savings. Most utilities show 12-month usage totals on December or January statements, or you can download usage history from your online account.
A typical U.S. home uses 10,500 kWh per year. If yours is significantly higher — due to electric heat, pool pumps, EV charging, or an older inefficient home — address the biggest efficiency gaps before sizing solar. Installing solar to offset a wasteful home is more expensive than first reducing consumption, then offsetting the remainder.
Step 2: Assess Your Roof
Solar panels perform best on south-facing roof sections with minimal shading between 9 AM and 3 PM. Before requesting quotes, honestly evaluate your roof:
- Age and condition: A roof with less than 10 years of remaining life should be replaced before solar installation. Removing and reinstalling panels to replace a roof later costs $3,000 to $6,000 in labor — avoiding this is worth the timing consideration.
- Orientation: South-facing is optimal. Southwest and southeast are good. East and west are viable with modest production reduction. North-facing is generally not viable.
- Shading: Trees, chimneys, dormers, and neighboring structures that shade panels during peak sun hours reduce output significantly. If shading is unavoidable, microinverters or power optimizers mitigate the impact better than string inverters.
- Available area: A typical 400-watt panel occupies about 22 square feet. A 10 kW system requires approximately 550 square feet of usable roof area.
Step 3: Research Incentives Before Getting Quotes
Understanding available incentives before you get quotes helps you evaluate the true cost and return on investment — and prevents installers from presenting inflated numbers as savings.
- Federal 30% Residential Clean Energy Credit: Reduces your federal income tax bill by 30% of the total system cost. On a $25,000 system, that is $7,500 off your tax liability. Applies through 2032.
- State tax credits: Many states offer additional credits stacking on top of the federal credit. Search your state energy office for current programs.
- Utility rebates: Some utilities offer upfront rebates for solar installation. These reduce system cost before the tax credit calculation.
- Net metering policy: Your utility\’s policy for crediting excess solar production determines the financial value of every kWh your system produces above your consumption. Understand this before sizing your system.
- Property tax exemption: Most states exempt solar installations from property tax assessment — your home value increases but your property tax bill does not.
Step 4: Get Multiple Quotes
Get at least three quotes from local installers before committing. Use the EnergySage Marketplace (energysage.com) to receive competing quotes from pre-screened installers — this platform creates transparency and typically produces quotes 10 to 20 percent below direct sales channel pricing.
What to compare across quotes:
- Cost per watt: The most useful normalized comparison metric. Divide total system cost by system size in watts. Average is $2.80 to $3.50/W before incentives in 2026.
- Panel brand and efficiency: Higher efficiency panels cost more but produce more from the same roof space.
- Inverter type: String inverter, microinverter, or power optimizer — each has pros and cons depending on your roof configuration.
- Production estimate: Annual kWh production estimate — ask how it was calculated and whether it uses NREL PVWatts data.
- Warranty terms: Panel performance warranty (25 to 30 years), product warranty (12 to 25 years), inverter warranty (10 to 25 years), workmanship warranty (typically 10 years from quality installers).
- Installer credentials: NABCEP certification is the gold standard in U.S. solar installation. Verify the company\’s license and insurance in your state.
Step 5: Review and Sign the Contract
Before signing, confirm the contract clearly specifies:
- Exact equipment brands and model numbers — not generic descriptions
- System size in kilowatts
- Projected annual production in kWh
- Total price and payment schedule
- Permit and interconnection handling — who pulls the permit and coordinates with the utility
- Workmanship warranty terms and what is covered
- Expected installation timeline from contract signing
Avoid contracts with production guarantees that seem unrealistically high — and be skeptical of \”free solar\” offers that are typically Power Purchase Agreements (PPAs) where you do not own the system and cannot claim the tax credit.
Step 6: Permitting and Design
After signing, your installer handles permit applications and system design. This phase typically takes two to eight weeks depending on your municipality\’s permitting office workload. Your installer submits structural and electrical drawings, and the permit is issued before installation begins. You do not need to do anything during this phase — just respond promptly if your installer requests additional information.
Step 7: Installation Day
A typical residential solar installation takes one to two days for a crew of two to three. The process involves mounting the racking system to your roof, attaching panels to the racking, running conduit and wiring from the roof to your electrical panel, installing the inverter, and connecting everything to the grid through a dedicated solar disconnect. Your installer will walk you through the completed system before leaving.
Step 8: Inspection and Utility Interconnection
After installation, your municipality inspects the system for code compliance. Once the inspection passes, your installer submits interconnection paperwork to your utility. The utility installs a new bi-directional meter that measures both what you consume from the grid and what you export to it. This final utility step typically takes two to six weeks. Your system cannot legally be turned on until both the inspection and interconnection are complete.
Step 9: System Activation and Monitoring Setup
Your installer activates the system and sets up your monitoring app. Spend 15 minutes learning the monitoring interface — daily production, consumption data, and any alerts. Verify the system is producing close to the estimated daily output in the first few days of full operation.
Step 10: Claim Your Tax Credit
When you file your federal income taxes for the year the system was installed, complete IRS Form 5695 to claim the 30% Residential Clean Energy Credit. Keep all installation receipts and invoices — your tax preparer or software will ask for the total qualifying cost. If your tax credit exceeds your tax liability for the year, the unused portion carries forward to future tax years.
Timeline Summary
- Research and quotes: 2 to 4 weeks
- Contract signed to installation start: 4 to 10 weeks (permitting)
- Installation: 1 to 2 days
- Inspection and interconnection: 2 to 6 weeks
- Total timeline from first quote to system on: 8 to 20 weeks
Bottom Line
Going solar is a significant but manageable project when you follow the steps in order. The homeowners who get the best outcomes are the ones who understand their energy usage first, research incentives before getting quotes, use a competitive quoting platform, and verify contract details before signing. The installers who win your business on merit — not sales pressure — are the ones worth working with.
