how do you get solar panels

Getting solar panels involves more than simply buying equipment online. It is a multi-step process that includes assessing your energy needs, evaluating your property, selecting the right equipment, securing financing, obtaining permits, and coordinating installation with a qualified professional. Whether you are a homeowner looking to reduce electricity bills or a business owner aiming to meet sustainability goals, understanding the full pathway to solar adoption is essential. This guide breaks down the process into five core topics, answers six frequently asked questions, and examines the market pain points and solutions that shape the solar industry today.

1. Assessing Your Property and Energy Needs Before Getting Solar Panels

Before you purchase a single panel, you need to determine whether your property is suitable for solar and how much energy you actually consume. This preliminary assessment prevents costly mistakes and ensures your system is sized correctly.

Evaluating Roof Condition, Orientation, and Shading

Solar panels require direct sunlight to generate electricity efficiently. The ideal roof faces south in the Northern Hemisphere (or north in the Southern Hemisphere) and has a tilt angle between 15 and 40 degrees. However, east- and west-facing roofs can still produce substantial energy, especially when paired with microinverters or power optimizers that mitigate shading losses.

Roof condition matters just as much as orientation. If your roof is older than 15 years or shows signs of damage, you should replace it before installing solar panels. Removing and reinstalling panels later adds significant labor costs. Shading from trees, chimneys, or neighboring buildings can reduce output by 10 to 25 percent, so a professional site survey using tools like Solmetric SunEye or Aurora Solar is recommended.

Calculating Your Energy Consumption and System Size

Review your past 12 months of electricity bills to calculate your average daily kilowatt-hour (kWh) usage. A typical U.S. household consumes about 30 kWh per day, while a small business might use 100 kWh or more. To size a system, divide your daily kWh usage by the peak sun hours available in your region. For example, if you use 30 kWh per day and receive 5 peak sun hours, you need a 6 kW system.

Home Size (sq ft)	Average Daily Usage (kWh)	Recommended System Size (kW)	Estimated Annual Production (kWh)
1,000	15	3	4,380
1,500	22	4.5	6,570
2,000	30	6	8,760
2,500	38	7.5	10,950
3,000	45	9	13,140

Keep in mind that these figures assume 4 to 5 peak sun hours per day. Areas like Arizona or Southern California may achieve 6 to 7 peak sun hours, while the Pacific Northwest or New England may only see 3 to 4. Adjust your system size accordingly.

2. Choosing the Right Solar Panels and Equipment

Once you know your energy requirements, the next step is selecting the appropriate solar panels, inverters, mounting hardware, and monitoring systems. The market offers three main types of solar panels, each with distinct advantages and trade-offs.

Types of Solar Panels: Monocrystalline, Polycrystalline, and Thin-Film

Monocrystalline panels are made from single-crystal silicon and offer the highest efficiency rates, typically between 20 and 23 percent. They perform better in low-light conditions and take up less roof space. Polycrystalline panels are made from multiple silicon fragments and have efficiencies of 15 to 17 percent. They cost less but require more surface area. Thin-film panels, including cadmium telluride (CdTe) and copper indium gallium selenide (CIGS), are flexible and lightweight but have efficiencies of 10 to 13 percent. They are often used in commercial installations with large, flat roofs.

Panel Type	Efficiency Range	Cost per Watt	Warranty (Years)	Best Use Case
Monocrystalline	20–23%	$0.80–$1.20	25–30	Residential roofs with limited space
Polycrystalline	15–17%	$0.60–$0.90	20–25	Budget-conscious installations
Thin-Film	10–13%	$0.50–$0.80	10–15	Large commercial or utility-scale projects

Inverters, Mounting Systems, and Monitoring

Inverters convert direct current (DC) electricity from panels into alternating current (AC) for home use. String inverters are the most affordable but are vulnerable to shading issues. Microinverters, installed on each panel, maximize output and offer panel-level monitoring. Power optimizers combine the benefits of both. Mounting systems must be corrosion-resistant and engineered for your roof type—asphalt shingle, metal, tile, or flat membrane. Monitoring systems, often accessible via smartphone apps, let you track production and detect faults in real time.

3. Financing Options for Getting Solar Panels

Solar panels represent a significant upfront investment, but several financing pathways reduce the burden. The best option depends on your tax situation, credit score, and long-term goals.

Cash Purchase, Solar Loans, and Leases

A cash purchase offers the highest long-term savings because you avoid interest and own the system outright. The average 6 kW system costs between $12,000 and $18,000 before incentives. Solar loans allow you to finance the system with monthly payments that are often lower than your current electric bill. Solar leases and power purchase agreements (PPAs) require no upfront cost, but you do not own the system and may face complications when selling your home.

Government Incentives and Tax Credits

In the United States, the federal Investment Tax Credit (ITC) allows you to deduct 30 percent of the system cost from your federal taxes. Many states offer additional rebates, property tax exemptions, and sales tax exemptions. The Database of State Incentives for Renewables & Efficiency (DSIRE) is an excellent resource for finding local programs.

Financing Option	Upfront Cost	Ownership	Average Monthly Payment	Best For
Cash Purchase	$12,000–$18,000	Yes	$0	Homeowners with savings and tax liability
Solar Loan	$0–$1,000	Yes	$80–$150	Those who want ownership without lump sum
Lease/PPA	$0	No	$50–$120	Renters or those with low credit scores

4. Permitting, Installation, and Grid Connection

Installing solar panels is not a do-it-yourself project for most homeowners. It requires electrical expertise, roofing knowledge, and compliance with local building codes. The process typically takes four to twelve weeks from contract signing to activation.

Step-by-Step Installation Timeline

Step 1: Site Survey and Design (1–2 weeks). An installer visits your property, measures your roof, inspects your electrical panel, and creates a custom system design.

Step 2: Permitting (2–6 weeks). Your installer submits plans to your local building department and utility company. Permit fees range from $200 to $1,500 depending on jurisdiction.

Step 3: Installation (1–3 days). A crew mounts the racking, attaches panels, runs wiring, and installs the inverter and meter. Most residential installations take one to three days.

Step 4: Inspection and Interconnection (2–4 weeks). A local inspector verifies compliance, and your utility installs a bidirectional meter. Once permission to operate (PTO) is granted, you can turn on the system.

Choosing a Qualified Solar Installer

Look for installers certified by the North American Board of Certified Energy Practitioners (NABCEP). Check reviews on SolarReviews, EnergySage, and the Better Business Bureau. Obtain at least three quotes and compare not just price but also equipment quality, warranty terms, and customer service. A reputable installer will provide a production guarantee and handle all permitting paperwork.

5. Maintenance, Monitoring, and Maximizing Solar Panel Performance

Solar panels require minimal maintenance, but a few habits ensure optimal performance over their 25- to 30-year lifespan.

Cleaning, Inspection, and Troubleshooting

Rain usually keeps panels clean, but in dusty or pollen-heavy regions, you may need to rinse them two to four times per year. Avoid abrasive cleaners and high-pressure washers. Inspect mounting hardware and wiring annually for corrosion or loose connections. Most monitoring apps alert you to drops in production, which may indicate shading, debris, or inverter faults.

Battery Storage and System Upgrades

Adding a battery, such as a Tesla Powerwall or Enphase IQ Battery, lets you store excess energy for nighttime use or outages. Batteries add $8,000 to $15,000 to your system cost but increase energy independence. You can also add more panels later if your energy needs grow, provided your inverter has spare capacity.

Maintenance Task	Frequency	Estimated Cost	DIY or Professional
Visual inspection	Quarterly	$0	DIY
Cleaning	2–4 times per year	$0–$300	DIY or professional
Inverter check	Annually	$0–$150	Professional
Wiring and mounting inspection	Every 3–5 years	$150–$400	Professional

Frequently Asked Questions About Getting Solar Panels

1. How much do solar panels cost in 2025?

As of 2025, the average cost of a residential solar panel system in the United States ranges from $2.50 to $3.50 per watt before incentives. For a typical 6 kW system, that translates to $15,000 to $21,000. After applying the 30 percent federal tax credit, your net cost drops to $10,500 to $14,700. Prices vary by state, installer, and equipment quality.

2. Can I install solar panels myself?

While it is technically possible to install solar panels yourself, it is not recommended for most homeowners. DIY installations often fail inspection, void warranties, and pose serious electrical and roof safety risks. Most jurisdictions require a licensed electrician to sign off on the grid connection. Hiring a certified installer ensures compliance and may be necessary to qualify for incentives.

3. How long does it take to get solar panels installed?

The entire process—from signing a contract to flipping the switch—typically takes four to twelve weeks. Installation itself takes one to three days, but permitting and utility interconnection often account for the longest delays. In areas with high demand or complex permitting, the timeline can extend to six months.

4. Do solar panels work on cloudy days or at night?

Solar panels still generate electricity on cloudy days, though output drops to 10–30 percent of clear-sky production. At night, panels produce nothing unless you have battery storage. Net metering policies in many states allow you to send excess daytime energy to the grid and draw from it at night, effectively using the grid as your battery.

5. What happens if I move after installing solar panels?

If you purchased your system outright, it typically increases your home’s resale value by about 4 percent, according to Zillow. If you have a lease or PPA, you must either transfer the agreement to the buyer or pay off the remaining balance. Solar loans must also be paid off or assumed by the buyer. Always disclose your solar agreement to potential buyers early in the sale process.

6. Are solar panels worth it in 2025?

For most homeowners with high electricity rates and sufficient sun exposure, solar panels are worth it. The average payback period is six to ten years, and panels last 25 to 30 years. With the 30 percent federal tax credit and rising utility rates, solar offers a predictable return on investment. However, if your roof needs replacement or you plan to move within five years, the financial case may be weaker.

Market Pain Points and Solutions in the Solar Industry

Despite rapid growth, the solar industry faces several persistent challenges that affect homeowners, installers, and utilities. Understanding these pain points—and the solutions emerging to address them—helps you navigate the market more effectively.

Pain Point 1: High Upfront Costs

Although prices have fallen dramatically over the past decade, the upfront cost of solar remains a barrier for many households. A $15,000 system is out of reach for families living paycheck to paycheck.

Solution: Solar loans with $0 down, leases, and PPAs eliminate upfront costs. Community solar programs allow you to subscribe to a shared solar farm and receive credits on your utility bill without installing anything on your roof. The federal ITC and state rebates further reduce the net cost.

Pain Point 2: Confusing Incentives and Paperwork

Federal, state, and local incentives vary widely, and navigating the paperwork can be overwhelming. Many homeowners miss out on available credits simply because they do not know they exist.

Solution: Use online tools like EnergySage, DSIRE, and Rewiring America’s calculator to identify all applicable incentives. Reputable installers handle incentive paperwork on your behalf. Third-party tax advisors can help you maximize the ITC, especially if you have complex tax situations.

Pain Point 3: Installer Quality and Scams

The solar industry has a reputation problem: fly-by-night installers, misleading sales tactics, and poor workmanship plague certain markets. Homeowners who choose the wrong installer face leaks, electrical fires, and voided warranties.

Solution: Always verify NABCEP certification, check licensing with your state contractor board, and read reviews on multiple platforms. Get at least three quotes and never sign a contract under pressure. Look for installers who offer production guarantees and comprehensive workmanship warranties of 10 years or more.

Pain Point 4: Grid Interconnection Delays

Utility companies often take weeks or months to approve grid connection, leaving homeowners with installed panels that cannot be turned on. In some regions, utilities have imposed caps on net metering, further slowing adoption.

Solution: Choose an installer with experience navigating your local utility’s interconnection process. Consider adding battery storage so you can use solar power before grid approval. Advocate for streamlined permitting through programs like SolarAPP+, which automates permit approvals in participating jurisdictions.

Pain Point 5: Roof Suitability and Shading

Not every roof is ideal for solar. Shading, orientation, age, and structural integrity can all limit production or increase costs.

Solution: Conduct a professional site survey before committing. If your roof is unsuitable, explore ground-mounted systems, community solar, or a solar carport. Microinverters and power optimizers can mitigate partial shading. If your roof needs replacement, bundle it with your solar installation to save on labor.

Pain Point 6: Maintenance and Performance Monitoring

Some homeowners worry that solar panels require constant upkeep or that performance will degrade unnoticed. Without monitoring, a faulty inverter or shaded panel can slash production for months.

Solution: Install a monitoring system with real-time alerts. Set a calendar reminder for annual inspections. Most panel manufacturers offer 25-year performance warranties guaranteeing at least 80 percent of original output. If production drops, contact your installer immediately—most issues are covered under warranty.
