When buying used solar panels, you need to know the following as a minimum:
1️⃣ When purchasing used panels, consider the type, system size, age, cost, and condition of the solar panels.
2️⃣ Only new solar panel installations can use the Feed-in-Tariff incentive.
3️⃣When you buy solar panels, look for damage like cracks and burn marks.
When you’ve decided to go solar for your home or business, you must consider how old they are. Solar panels have a lifespan of twenty-five to thirty years and more.
Factors beyond your control, like extreme weather conditions, will affect the lifespan of those solar panels.
Secondhand panels will pay for themselves between five and ten years. In contrast, new systems will pay for themselves between nine and twelve years. Therefore, it is essential to know the system’s age and whether they maintained it.
🎓 What You Need To Know When Buying Used Solar Panels
When considering purchasing solar panels, you need to determine how many sun hours you get regularly. There are online calculators available to assist you in this matter. Also, the solar company that helps you with your installation will be able to give you the information you need.
Solar panels don’t work at night and do not work well when it is cloudy.
Because solar panels depend on sunlight, you need to consider which way your house faces. For example, do you have a south-facing roof in the northern hemisphere or a north-facing roof in the south-facing hemisphere?
The average house consumes less energy than the majority of solar systems generate. As a result, your solar battery system saves the extra energy generated by your solar system during the day.
Your house is powered by the solar battery solution when your solar system is not working at night. You could even run entirely independently of the grid, depending on the technical specifications of your system.
If you have a grid-tied system, your solar panels will send any extra electricity back to the utility company through the electrical grid.
The power company will give you credit for any power your system doesn’t use. So, for example, you can use the free credits you receive from your utility company to purchase free electricity. Unfortunately, this only applies to new certified installations.
🔎 What To Look For When Buying Used Solar Panels
When buying used solar power systems, you must ensure they are in good working order. In addition, check for physical damage like cracks and broken connectors and look for the following:
1️⃣ Make sure that the used solar panels are in working condition:
Test the used solar panels with a multimeter to determine if they produce the specified amps and volts.
Point the solar panels toward the sun and test them for a few minutes while the panels warm up. They should work if you get the required amps and volts.
2️⃣ Check used solar panels for loose connections:
The cells in Solar panels together make up the circuitry that produces the power output. If there are loose connections between them, they will not work optimally.
3️⃣ Used solar panels produce less power than new ones:
With each year that goes by, your panels produce less energy. New solar panels will be more efficient because technology is improving, and you need to consider the age of your solar panel.
Older solar panels are physically bigger and use more space on your roof, whereas newer ones are smaller. Does your roof have enough room for the solar panels to produce the output you need?
4️⃣ Check your used solar panels for damage:
Typically, used solar panels get exposed to weather conditions, like rain, dust, small rocks, hail, and debris.
So, check for visible damage, like small cracks, moisture, and broken connections, and they may not be easy to spot.
5️⃣ Installing used solar panels:
Do you have a working knowledge of solar panel systems? Do you have the electrical and technical expertise to install solar panels yourself?
If you need more expertise, getting a company to do the installation for you might be better. Finding a company willing to use the secondhand equipment you bought might be challenging.
⚠️ If you want to be the one who takes care of the solar installation, you should research, get quotes, and ensure you will only end up with solar equipment that can be used or installed.
💰 What Are Used Solar Panels Worth?
Used Solar panels differ in price depending on their age, specification, and condition.
Refurbished solar panels are worth approximately fifty to seventy-five percent of the price of new ones, depending on their condition, specification, and age. In contrast, used solar panels cost about ten to sixty cents per watt.
The value of used solar panels depends on factors like:
- Solar panels might be worth purchasing if you have your “own” property, as this might increase the value of your house.
- If your electric bill is high, it might be worth purchasing solar panels, as this will save you money in the long run.
- It might be worth purchasing solar panels if you get a reasonable price.
- The age of used solar panels plays a significant role in their value.
