| Power Tolerance | Indicates how much the actual power output of the panel can deviate from its rated power. A lower tolerance (e.g., 0/+3%) is better, ensuring consistent performance. |
| Temperature Coefficient | Measures how much the panel’s performance decreases as its temperature rises. A lower negative number (e.g., -0.35%/°C) indicates better performance in hot conditions. |
| Panel Type | Monocrystalline panels are generally more efficient and durable than polycrystalline panels, though they may be more expensive. Thin-film panels are less efficient but can be more flexible and cost-effective. |
2.2. Understanding Solar Panel Warranties
Warranties are vital for rooftop solar systems, designed to last 25 years or more. Reputable manufacturers usually offer two types of warranties:
- Product Warranty: Covers defects in materials and workmanship. Aim for at least 12 years, with top brands offering 25 years.
- Production Warranty: Guarantees how the panel will degrade over time. Most panels degrade around 0.5% annually, while top brands degrade at about 0.25%.
Additionally, check if the installer offers a separate warranty covering the installation work. This should cover repairs and damages from workmanship and penetrations. Longer warranty terms generally indicate higher confidence in the product’s durability.
2.3. Inverters And Microinverters: Choosing The Right Type
A solar inverter is a critical component that converts DC solar power to AC power for home use. There are two main types:
- String Inverters: Suitable for simple installations, accepting output from all panels in an array.
- Microinverters: Ideal for complicated designs, handling output from one or two panels.
2.4. Solar Batteries: Assessing Your Storage Needs
Solar batteries are an optional but increasingly popular addition, with 28% of new solar installations including energy storage. Batteries are beneficial for:
- Homeowners wanting backup power during outages.
- Those on time-of-use rate plans.
- Locations without net metering.
Choosing a reputable brand is crucial. Look for customer reviews to find the best solar battery for your needs. Also, consider the following features:
| Feature | Description |
|---|---|
| Usable Energy Capacity | Total amount of energy the battery can store and deliver. |
| Power Output | Maximum rate at which the battery can discharge energy. |
| Round-Trip Efficiency | Percentage of energy that can be retrieved from the battery compared to the energy used to charge it. |
| Depth of Discharge (DoD) | Percentage of the battery’s capacity that can be used without damaging the battery. Higher DoD is preferable. |
3. System Specifications: Size And Energy Production
A solar quote should detail how the system is expected to perform over time.
3.1. Understanding System Size (kW)
System size refers to the kilowatts (kW) of direct current (DC) power the solar installation can generate under full sun. The average home solar system is around 6 kW. However, the optimal size depends on electricity usage and roof size. When comparing quotes, system sizes should be similar. Significant deviations should be questioned and justified by the installer based on energy usage or roof limitations.
3.2. Estimating Energy Production
Solar energy production estimates depend on:
- System size in kW.
- Latitude and annual weather conditions.
- Roof direction (azimuth).
- Roof tilt angle.
- Shade from trees and other structures.
Installers should provide accurate estimates using advanced modeling software. Tools like PVwatts can verify these estimates. Discrepancies exceeding 5% should be explained, accounting for panel brand differences or planned tree trimming.
3.3. Battery Specifications: Capacity And Output
If opting for a solar battery, key details include:
- Total usable energy capacity.
- Maximum continuous battery power output.
- Cost for the battery installation.
The right capacity and output depend on your needs. High capacity and output are necessary for running power-hungry appliances during outages. Cost per kWh of storage helps compare batteries effectively. Some battery prices include inverters (AC-coupled), while others don’t (Tesla Powerwall 3 includes a solar inverter). Keep this in mind when comparing solar battery quotes.
4. Costs And Financing: Making Sense Of The Numbers
Comparing costs involves looking at more than just the bottom line.
4.1. Analyzing Cost Per Watt
To compare solar quotes, use the cost per watt metric, calculated by dividing the total system cost by the system’s peak-rated output in watts DC. The average cost in the U.S. is around $3.00 per watt. Factors like location and roof features affect this cost. A lower cost per watt generally indicates better value.
4.2. Balancing Cost With Quality
While cost is important, the cheapest option isn’t always best. Weigh costs against the quality of equipment, warranties, and customer service. Choose the best company for your needs at a good price. For battery systems, get a breakdown of separate costs for solar and batteries, focusing on dollars per kilowatt-hour of energy storage when comparing.
4.3. Understanding Solar Incentives
The federal solar tax credit offers up to 30% of the installation cost back as a tax credit. State, city, and utility incentives also exist, with installers often ensuring you receive all eligible incentives. Some incentives are immediate, while others, like SRECs, are paid over time. Understand how each incentive works before signing a contract.
4.4. Financing Options: Loans And Leases
If upfront costs are a concern, explore solar financing options:
- Pay with cash or a loan.
- Lease the panels from the installation company.
Solar loans can help you go solar with no money down, paying off the cost with savings from the installation. Be cautious of hidden fees and requirements to pay a portion of the loan equal to the value of the tax credit within the first year or two.
5. Energy Bill Savings: Evaluating The Estimates
Deciding whether the savings estimates are accurate is crucial.
5.1. Estimating Long-Term Savings
Installers use software to estimate energy bill savings, ongoing incentives, and loan payments, projecting cumulative solar savings over the system’s lifetime. The installer should explain the inputs for calculating savings and understand how your utility company reimburses solar owners for excess energy (net metering or other buyback plans).
5.2. Accounting For Electricity Rate Increases
The projected electricity rate increase significantly impacts potential lifetime savings. From 1960 to 2022, the average rate of increase was about 2.9%. If an installer estimates much higher, they must provide a solid explanation, such as an approved multi-year rate increase. Anything less than certainty that electricity rates will rise above historical levels is potentially misleading.
