What is guaranteed production for solar?

Increasing incentives and decreasing costs make a solar investment incredibly advantageous, but the price tag is not cheap. When purchasing a solar system, also known as a photovoltaic (PV) system, you want to verify that your investment will be worthwhile. Therefore, it is essential to comprehend the equipment's estimated lifetime and energy production. When establishing a PV system, many solar providers will guarantee a set level of electricity generation to provide peace of mind. This page explains solar power production guarantees, what happens when a system's production falls short of the specified quantity, and why some solar businesses do not offer this for residential solar panel systems.

What is a production guarantee for solar energy?
Solar power production guarantees are a means for solar contractors to stand behind the systems they install by ensuring that your solar system will produce a specified amount of energy within a certain timeframe. For instance, a one-year 90 percent production guarantee is essentially a commitment from your installer that your PV system will produce at least 90 percent of a set amount of kilowatt-hours (kWh) during the first year of operation, or you will be compensated accordingly.

The system size, design, equipment, and local climate are frequent aspects that influence the assured generation of solar energy. However, there is no industry-leading standard for the guaranteed production of solar panel products at the present time. There are one-year production guarantees and decades-long production guarantees. Not all installers give a production guarantee, and those that do may employ different estimation models. In general, however, solar power output guarantees can aid in calculating the return on investment and evaluating the performance of a system when comparing solar solutions.

What happens if your system's output falls short of the guaranteed output?

As indicated previously, production guarantees (and their terms and conditions) differ across the solar sector. In most cases, however, the installer will pay you if the actual output of your system falls short of the guaranteed output. Your installer may compensate you in several ways, including monetary compensation or system maintenance and repairs.

Solar panels have a 30-year lifespan during which their efficiency diminishes steadily. The purpose of production guarantees is to protect your investment from early depreciation. Therefore, it is normal for them to barely endure a year. If you observe that the production of your solar panels has decreased after 15 years, the production guarantee likely no longer applies. Alternatively, the promised output will certainly decline over time if you have a long-term (10 to 30 years) production guarantee.

What if your solar installer does not guarantee production?
If your solar installer does not originally include a manufacturing guarantee in your solar estimate, the first step is to inquire whether or not they can give one. Although it would be ideal, there are several reasons why installers may be reluctant to offer a production guarantee. The installer may be working on their estimation models and unable to precisely protect the system's promised output. In addition, the unpredictability of the weather makes it impossible for installers to provide homeowners with accurate production estimates. Guaranteed solar production is valuable and can provide peace of mind when investing in a PV system, but you shouldn't dismiss an installer just because he or she does not offer it.

Solar panel manufacture guarantees versus warranties
Importantly, production warranties only cover the production of solar energy, not the panels that permit it. Although production guarantees are sometimes called "production warranties," they do not cover materials like a manufacturer's warranty. Typically, the panels and inverters of a residential solar power system are protected by different warranties.

Additionally, a manufacturing guarantee and a performance guarantee are distinct. Solar panel manufacturers typically provide performance guarantees. They are intended to safeguard your investment from early panel deterioration. However, if weather, shading, or the orientation of your solar panels are the primary reason for low solar production, a performance guarantee may not cover those factors. In contrast, solar installers typically provide production guarantees that account for these variables in their initial projections.
