Three Tips To Make Your Home Solar Panels Last Longer
The great thing about solar panels is that they require very little maintenance. Regular solar panel cleaning is generally unnecessary unless your area is highly susceptible to dust, dirt, pollen, or sand due to an arid climate.4
While solar panels generally require little maintenance, its still important to inspect your solar panels from time to time and monitor their performance. Here are a few tips to ensure your solar installation is working at its full capacity:5
What Happens If My Solar Company Goes Out Of Business Before My Warranty Expires
If your solar panels last longer than the company that installed them, but a problem normally covered by their warranty arises, you are out of luck unless the company made other arrangements to cover the warranties of its existing customers.
But dont count on it.
Fortunately, its possible to insure your residential solar system with an independent insurer to avoid a potential catastrophe like a bankrupt solar company just when you needed them.
In fact, you will receive a new warranty longer and more comprehensive than the original from the now-defunct solar installer.
Be sure to read the fine print before signing on, though. Only select solar module and inverter manufacturers are covered.
Ways To Reuse Spent Solar Panels
When you decide its time to make a change in how you produce solar energy at home whether its 30 or 50 years after first installing rooftop solar you have several options for dealing with the spent solar panels.
You may wish to:
- Enlarge your existing solar array by adding new panels to make up for the natural energy loss due to degradation of your original installation.
- Donate the spent panels to an organization that will install them elsewhere to offset energy costs for a qualified family or business.

How To Maintain Them
If you keep your solar panels well maintained, then you can expect to enjoy them for the full length of their estimated lifespan. There are a few ways in which you can do this, helping the efficiency levels to stay at their best.
While solar panels should be pretty much self-sufficient after installation, an annual clean can really help them stay maintained. It is important to note that you only need to give your solar panels a good clean once or twice a year, but if you have had a long period with no rain, you may want to give them an extra once over.
Here are some quick cleaning tips:
- Clean your solar panels in the morning or evening as they can get very hot during the day
- You should always start by gently sweeping leaves and debris from the surface of the panel. Make sure you used a soft bristled brush
- Spray the panels with your garden hose, but use a gentle stream
- If the panels need a few stubborn areas cleaned further, wipe them down with warm water and a soft cloth to avoid scratching
Safety precautions when cleaning:
- You should always refer to the manufacturers guide before you use any cleaning products on the panels
- Always take precautions when reaching the panels, as they tend to be quite high. If in doubt, there are professional panel cleaners that you can call
- Only ever clean the surface of the panels, never touch the wiring underneath. You can use a solar panel cleaning service for under the panels, as they are trained and qualified

Things To Consider Before Installing Solar Pv Panels
Before you install solar PV panels, there are a few things you need to take into account. The first is the cost of the panels themselves as well as the cost of installation. Solar PV panels are a significant investment, so you want to make sure that you can afford it. Its also important to determine the amount of sunlight your area gets. Solar PV panels need direct sunlight to work properly, so if you live in an area with a lot of trees or clouds, you may not get enough sun to make the panels worth it.
Consider your energy usage as well. If you have a high energy usage, solar PV panel installation will be more expensive. However, if you use very little energy, the upfront cost may not be worth it. When it comes to maintenance, solar PV panels require very little, but you will need to clean them periodically to ensure they are working properly.
Do Solar Panels Need To Be Cleaned
Solar panels are easy to maintain but to keep production stable, you should get them cleaned once a year. If you live in an area that tends to have a lot of dust, this may affect your production, in which case youll want to get them cleaned more often. Youll want to keep an eye on your systems functionality by reviewing your energy bills and usage month-to-month. If your electric bill starts creeping up, it may be time to clean your solar panels. If you are in an area that gets rain regularly, your panels will likely get the right amount of cleaning and produce plenty of energy! Its essential to monitor your solar production on your monitoring app so you can address any issues right away.
There are many different companies that offer panel cleaning on an annual or bi-annual basis. For those who prefer to DIY, another option would be to purchase an extendable pole with a window cleaning tool. This, along with a garden hose, should be able to handle any panel cleaning needs that your system has. Plain water works the best, as more potent chemicals can interact with your solar panels in negative ways. Solar panels get hot, so you will want to clean your panels on overcast days and when temperatures are low.
In addition to knowing how long solar panels last, knowing how long your solar batteries last allows you to be proactive when taking care of your solar battery, which can prolong the lifespan to exceed the 10-year warranty.

Do Solar Panels Really Last 25 Years
They can! The standard lifespan for solar panels is 25-30 years. But this is only if you choose high-quality solar panels that come with warranties that guarantee your panels will keep producing throughout this average lifespan. Some manufacturers offer warranties for the entire standard lifespan of 25 years.

After 25 Years What Happens
The majority of panels installed in Ireland are still under 10 years old. Due to the fact that PV technology is still relatively new theres not a huge amount of data available that indicates what will happen after 25 years with the exception of a slow decrease in efficiency. A 2012 study by the National Renewable Energy Laboratory found the solar panel degradation rate to be 0.8 percent each year but even this has improved since the research was conducted.
An added bonus of the lengthy lifespan is that you dont need to worry about your solar panels carbon footprint. Over 25-30 years they will have produced enough clean energy to offset the energy that was used to make them in the first place. This is known as energy payback time or EPBT.
Setting Up Solar Panels For Optimal Energy Production
To get the most energy from solar panels for as long as possible, their placement angle and orientation in relation to the sun are critical.
Facing due south
Ideally, arrange your solar panels so that they are directly in front of the sun when the sun is at its highest point in the sky. This orientation corresponds to an azimuth angle of 180 degrees.
If your roof is not south-facing, a ground mounted system may work better for you. Youd be able to set up a solar array facing due south on your property.
Avoid solar panel shading
Both trees and buildings could block all or part of your PV panels at some point during the suns trajectory in the sky each day.
Microinverters will minimize this issue.
Use the optimal solar panel tilt angle
The manner in which your solar panels are tilted in relation to the sun is important in increasing the power production of your solar panels. This is known as the tilt angle.
Ideally, you want your solar panels to receive incoming solar rays directly perpendicular to your PV modules for maximum energy production.
For solar panels that are stationary , it is common to hear that a tilt angle of 15 degrees added to your latitude in winter or subtracted from your latitude in summer, or simply an angle equal to your latitude, is the best for optimal power performance from solar panels.
This advice is too general and wont result in a solar setup optimized for peak power performance all year long.

How Much Electricity Do Solar Panels Produce
Of all the features of a solar panel, the most noteworthy is how much energy it generates. Consumers should carefully weigh whether switching to solar is worth the effort before committing. And this question can be answered by determining how much energy roof-mounted panels can produce.
As well as whether solar can meet the long-term demands of a home or business that was once powered by other energy sources. To determine this, lets ingest some basics, shall we?
Solar panels are rated in watts, and the SI unit is used to measure power production. In practice, most solar panels for residential properties produce between 250 and 400 Watts of electricity per day.
You can determine how much electricity a panel will produce in a day by using this formula.
Power x Average hours of direct sunlight = Daily Watt-hours
For example, if a 100W solar panel receives eight hours of sunlight daily, the total power output is then calculated by multiplying 100W x 8 = 800Wh or 0.8 kWh
Nonetheless, the amount of electricity a panel produces will vary depending on a number of factors. For example, the power rating, the number of hours of sunlight per day, the efficiency of the panel, how clean it is, etc.
So, when deciding the size and capacity of ones sought solar system, it is best to put these factors into careful consideration, and aim for the upper limit to accommodate these variations.
Make Your Solar Panels Last Longer Through Regular Maintenance
Even though solar panels do not have any moving parts, a good idea is to ask your installer or O& M provider to regularly examine your PV system.
A regular onsite checkup may discover the odd loose mounting screw, exposed wires and maintain overall system health.
All simple preventative measures can prevent falling panels in strong winds or fires from arcing wires.

Do Solar Panels Last Forever
Do solar panels last forever you ask? No. However, their lifespan is impressive and with technology continuously improving, their longevity is only likely to continue increasing. Its important to know how long your panels will last so you can get an indication of how long it should take you to recover the money laid out for them. That said, if you go to a trusted provider such as Caldor, where we will only install panels where its a worthwhile investment, youre going to make savings within a few years. Lets take a deeper dive into this question.
Can We Accurately Estimate Solar Panel Lifespan
Since most homeowners are looking for solar pv power to help reduce their electricity costs, it makes sense that you want to predict the life of your solar panels. If you can determine the life expectancy of solar panels accurately, you can calculate the long-term value they offer.
The problem with discussing solar panel lifespan is that solar panels dont just produce the same amount of power for 20 years, and then suddenly stop producing electricity completely. Instead, they slowly degrade over time, producing less and less power as they get older. Homeowners then have to determine when it’s worth replacing those older panels with new panels to get back to maximum energy generation.
The industry uses 25 years as the average solar panel lifespan because data shows thats the amount of time in which most people still receive enough production from their panels to meet their homes energy consumption needs. So if youre wondering how long do solar panels last, a safe answer is around 25 years.

When To Consider Replacement
As you can see, solar panels will continue to produce energy for you after 25 years as long as you keep them well maintained. Even if youve taken all of the steps to maintain your solar panels, you should know that they will not be as efficient as when you first started using them.
Thats why you must pay attention to their productivity. As long as your panels produce enough electricity to cover the needs of your home, you dont need to replace them. If your electricity bill is going up and your solar panels are not generating enough electricity for your home, its probably time to replace them.
