Evaluating Equipment: Quality and Warranties Matter
The heart of your solar system lies in its components. When you compare solar prices, don’t overlook the quality and warranties of the equipment being offered.
Solar Panels: Brand, Model, and Specifications
Solar panels are not created equal. Different brands utilize varying materials and manufacturing processes, which directly impact performance and longevity. When comparing solar quotes, note the brand and model number of the proposed solar panels. This allows you to research solar panel specifications online and understand key factors like efficiency, temperature coefficient, and power tolerance.
Keep in mind that solar installers often order panels in advance, and the exact model quoted may not be available at installation time. Be prepared to compare any substitute panels against the originally quoted specifications. If a change is necessary, ensure the new panels meet or exceed the performance of the original ones, and don’t hesitate to negotiate pricing if there’s a downgrade in quality.
Solar Warranties: Protecting Your Investment
Warranties are a critical aspect of comparing solar prices. Solar panels are a long-term investment designed to last for 25 years or more, so robust warranty coverage is essential. Reputable manufacturers typically offer two types of solar panel warranties:
- Product Warranty: Covers manufacturing defects and workmanship. Aim for at least a 12-year product warranty, with premium brands offering 25 years.
- Performance Warranty: Guarantees the panel’s power output over time. Most panels degrade at around 0.5% annually, ensuring about 87.5% output after 25 years. Top brands often offer even better degradation rates, around 0.25% per year.
In addition to manufacturer warranties, inquire about the installer’s workmanship warranty, which covers the installation itself. This should protect against issues arising from installation errors or roof penetrations. Longer warranty terms generally indicate greater peace of mind and better long-term value when comparing solar prices.
Inverters and Microinverters: Converting Sunlight to Usable Power
The solar inverter is the brain of your solar system, converting DC electricity from panels to AC for your home. Quotes will typically include either string inverters or microinverters. String inverters are cost-effective for simpler systems, while microinverters, attached to individual panels, are beneficial for complex roofs or shaded conditions.
Understand which type of inverter is proposed and why. Both have pros and cons, and the best choice depends on your specific home. Ensure the quote specifies the inverter brand, model, and warranty.
Batteries: Optional Energy Storage
Solar batteries are an optional but increasingly popular addition, especially for backup power, time-of-use rate optimization, or off-grid living. If you’re considering battery storage, compare solar prices based on battery brands, models, usable capacity (kWh), power output (kW), and warranty. Just like panels, reputable battery brands are crucial for performance and longevity. Compare the cost per kWh of storage to assess the value proposition of different battery options.
Note that some battery systems, like the Tesla Powerwall 3, may include integrated inverters, which can affect price comparisons with AC-coupled batteries like Enphase IQ, which require separate inverters.
System Performance: Size and Estimated Production
Beyond equipment, comparing solar prices effectively requires understanding the proposed system’s performance.
System Size: Kilowatts (kW) and Your Energy Needs
System size, measured in kilowatts (kW), indicates the system’s power generation capacity under ideal conditions. The average home solar system size is around 6 kW, but your ideal size depends on your energy consumption and roof space. When comparing solar prices, system sizes quoted should be relatively similar, reflecting your energy needs. If you notice significant size variations, ask the installer to explain their sizing rationale based on your energy usage or roof limitations. Understanding how many solar panels you need is a key step before comparing quotes.
Energy Production Estimates: Predicting System Output
Installers use sophisticated software to estimate your system’s annual energy production, considering factors like:
- System size (kW)
- Location (latitude and weather)
- Roof direction (azimuth)
- Roof tilt
- Shade analysis
Production estimates are crucial for calculating savings. While slight variations are normal, significant discrepancies (over 5%) between quotes warrant scrutiny. Use tools like PVwatts, a government-developed calculator, to verify production estimates independently. Question installers about substantial deviations and understand if they account for factors like tree trimming costs, which can impact the overall value proposition.
Battery Specifications: Capacity and Output for Your Needs
For quotes including batteries, compare usable energy capacity (total energy stored) and power output (rate of energy discharge). Higher capacity and output are needed for extended backup or running energy-intensive appliances. Assess your specific needs – backup for essential appliances requires less storage than whole-home backup. Cost per kWh of storage is a useful metric for direct battery price comparison.
Cost and Financing: Understanding the Numbers
Comparing solar prices isn’t just about the bottom line; it’s about understanding the cost structure and financing options.
Cost Per Watt: A Standardized Price Comparison
To compare solar prices across different system sizes, use the “cost per watt” metric. Calculate it by dividing the total system cost by the system size in watts (kW x 1000). This standardized metric allows for apples-to-apples price comparisons. The average cost of solar panels nationally is around $3.00 per watt, but this varies by location and system specifics. While a lower cost per watt is generally better, prioritize overall value, considering equipment, warranties, and installer reputation, not just the absolute lowest price. Remember, separating battery costs from solar system costs is crucial for accurate price comparisons if batteries are included. For batteries, use “dollars per kilowatt-hour of energy storage” for comparison.
Solar Incentives: Reducing Your Upfront Investment
Solar incentives significantly impact the final cost. The federal solar tax credit offers a 30% credit on system costs. State, local, and utility incentives can further reduce expenses. Installers should factor in applicable incentives into their quotes. Understand how each incentive is applied – some are upfront reductions, while others, like SRECs, are paid over time. Ensure you fully grasp the incentive details before committing.
Financing Options: Loans, Leases, and Cash Purchases
Solar financing is common. Quotes may include cash purchase prices and financing options like solar loans or leases. Loans allow ownership and tax credit eligibility, while leases involve renting the system. Be cautious with loans, as some include dealer fees or require early tax credit repayment. Compare loan terms, APR, and fees carefully. A guide to solar panel financing can provide in-depth information. Request both cash and financed quotes to understand the true cost difference and explore external financing options for potentially better rates.
Energy Bill Savings: Projecting Your Financial Returns
Estimating energy bill savings is complex but vital for comparing solar prices. Installers use software to project savings based on:
- System production estimates
- Local electricity rates
- Utility net metering or buyback policies
- Projected electricity rate increases
Review these assumptions carefully. Understand how your utility credits solar energy and the estimated electricity rate increase. While a historical average increase is around 2.9%, overly optimistic projections (much higher than 3% without solid justification) can inflate savings estimates unrealistically and should be questioned. Residential solar installers inflating utility cost increases is a concerning practice to be aware of.
Tips for Securing the Best Solar Prices
To get the most competitive solar prices and ensure you’re comparing apples to apples:
- Check Customer Reviews: Research online reviews to gauge installer reputation and customer service quality. Companies with consistently negative feedback should be approached with caution.
- Understand Local Incentives: Familiarize yourself with local, state, and federal solar incentives and net metering policies to better interpret quotes and ensure all applicable savings are included.
- Request Cash and Finance Quotes: Compare both cash purchase prices and financed options to understand the cost implications of financing and explore better financing alternatives if needed.
- Utilize Solar Comparison Platforms: Platforms like SolarReviews can help you obtain multiple quotes from vetted installers, fostering competition and potentially securing better pricing and deals.
