What Are the Options for Mounting Solar Panels?

Picking the right way to set up your solar panels is key, just like picking the panels themselves. How you mount them decides if they stay put, how much power you get, and if they can handle wind, snow, and weather over time. These days, solar setups—from homes to big power plants—use all sorts of mounts made for different spots and uses.

Rooftop Mounts

These are super common, mainly for homes and businesses. They stick right onto the roof and usually come in two types: ones for slanted roofs and ones for flat roofs.

  • Slanted Roof Mounts:These use rails, hooks, or clamps to match the roof's angle. They work roofs made of tile, metal, or shingles.
  • Flat Roof Mounts:These often use heavy stuff to hold them down or designs that don’t drill into the roof too much. This keeps the roof waterproof while still letting you tilt the panels for the best sun.

Ground Mounts

You see these a lot in big and rural setups. The panels go on frames made of steel or aluminum that are stuck in the ground with poles, screws, or concrete. You can tilt and turn them however you want, so it’s easier to get the most power. Plus, they’re easy to get to for fixing and cleaning. Great for solar farms and farms in general!

Solar Carports

These do two things: make power and give you covered parking! The panels are on steel or aluminum frames that can hold up the panels and handle the weather. They're popular at businesses, shopping spots, and industrial parks, turning parking lots into power plants.

Floating Solar Mounts

These use stuff that floats to hold solar panels on water like lakes or ponds. They save space and can make the panels work better because the water cools them down. The mounts have to not rust and be built to handle waves, wind, and changing water levels.

Pole Mounts

These hold panels on a single pole or a few posts. You often see them in small or off-grid setups, like farms or far-off places. Some let you change the tilt with the seasons to get more power all year.

Tracking Mounts

These are fancy mounts that move the panels to follow the sun. Some turn from east to west, and others tilt and turn. They're pricer and more complex, but they can really boost power output in big projects.

No matter what you pick, good quality is a must. Companies like SIC Solar specialize in making and selling solar mounting gear. They’ve got tough, flexible options for roofs, ground, carports, and more, to suit all sorts of setups. Good mounts are key for keeping everything steady, easy to put together, and working well for years in any place.

What Questions to Ask When Installing Solar Panels?

Putting in solar panels is a commitment for years to come, so asking sharp questions before you start and as you go can really change how well the system runs, how safe it is, and if you get your money's worth. No matter if it's for a house, store, or big power plant, talking openly with the people putting it in and where they get their stuff helps keep you from wasting cash on mistakes.

Can My Place Even Use Solar?

First off, see if solar even works where you are. Look at your roof – what shape it's in, what kind it is, which way it faces, if anything blocks the sun, and how much space you've got. If you're thinking about putting panels on the ground or on a carport, check the dirt and if you have enough land. Figuring this out early means you can find the right way to set things up, instead of trying to make do later.

What Kind of Setup Will They Use?

Not every way of setting up solar panels is the same. Ask if they're going on the roof, ground, carport, or balcony, and why they think that's the way to go. Figure out if the panels will be at a fixed angle or if you can change them, and how they'll handle wind and snow. SIC Solar companies that make and sell these setups usually plan things based on the weather and what the building can handle, so it stays put for a long time.

What About Wind, Snow, and Bad Weather?

How well it holds up against the weather is super important. Ask what rules they're following and how they're making sure the system can handle wind, snow, and rust. This really counts if you're near the coast or where it's always windy. What they make it out of – like types of aluminum or steel – matters a lot for how long it lasts.

Will Putting the Panels on Mess Up My Roof?

If they're going on the roof, ask how they'll stick the setup on and if they need to drill any holes. If they do, see how they'll keep water from leaking in. For flat roofs, they might just weigh the system down, but slanted roofs usually use hooks or rails. Knowing this stuff beforehand helps keep your building safe and stops leaks later on.

What Do I Need to Do to Keep It Working?

Solar setups usually don't need a ton of work, but the stuff holding them up needs to be checked now and then. Ask how often you should look at it, what parts wear out the quickest, and how easy it is to swap stuff out if you need to. A good setup makes it easier to keep things running and cuts costs in the long run.

Can I Add More Panels Later?

If you think you might need more power later, ask if you can add more panels to the setup. If it's made so you can easily snap more panels on, you can do that without changing the whole thing, which is something to think about for businesses.

What Rules and Okay's Does It Follow?

Ask what worldwide or local rules the setup follows. If it has certifications for being strong, not rusting, and being made well, you can trust it'll work. Good companies usually make their stuff to meet a bunch of rules so they can sell it all over.

Who's Deciding How It's Made?

Make sure you know if the setup is made just for your place or if it's a standard design. Having pros plan it out means it'll fit your spot just right. Companies that handle the planning and making themselves often do a better job of making sure everything works together from start to finish.

By asking these questions first, the people buying and putting in solar panels can work better together, lower risks, and be sure the system works safely and well for as long as it should.

Which Solar Panel Is Best for Agriculture Purposes?

Solar energy? Big deal for farms now. Think powering water pumps, electric fences, even keeping barns cool. Solar helps cut costs, get greener, and produce more. But heads up, not all panels are the same for farm work. Picking right is key!

agricultural solar mounting

Monocrystalline Panels: Small Space? No Problem

A lot of farms like monocrystalline solar panels best. They're made with fancy silicon, so they're hot stuff at turning sunlight into power, even when it's a little shady. They make more juice from less space, so these are great if you don't have a ton of room or need max power.

Plus, they look cool and dark, which means they don't get as hot. That's good if you're in a hot place. Put them on the ground, over your car, or up high over crops, and you've got power for pumps, greenhouses, or milking stuff.

Polycrystalline Panels: Solid and Cheaper

Then there are polycrystalline solar panels. Usually, they cost less than the others. They're made from a bunch of silicon bits, so they're not quite as good at making power, but they're still not bad. If you've got lots of land, these can save you cash while still getting you energy. If you've got room to spread out, these are good at getting you power for less money at first.

Bifacial Panels: Bonus Power from the Ground

Got a bright, shiny farmyard? Bifacial solar panels might be cool. They grab sun from the front and back, so they get extra power from light bouncing off the ground. If you put panels up high over fields to grow crops underneath, bifacial panels can mean more power without needing more space.

Mixing Panels with Crops

Putting solar panels right over crops? It's a thing! You've gotta be picky about panels and how you set them up. You need to hang the panels high enough, so sunlight still gets to the plants. So, you plan panel power and plant light carefully together.

SIC Solar companies make the stuff to hold up the panels. They build strong frames you can adjust for farms. They help put panels at the right height and angle, so you can still farm underneath.

Built to Last

Farms are rough places. Dust, wet, chemicals, wind are everywhere. Solar panels for farms need good warranties, be tough, and not rust. Pair them with strong frames that can handle being outside, and they should last, even when things get bad.

Matching Panels to Needs

What panels are best? It boils down to what power you need, how much space you have, your budget, and the weather. Monocrystalline panels often top the list for best power in small areas. Polycrystalline and bifacial panels are cool if you have different goals or land. Plan well, pick smart, and work with good frame sellers. Then, farms can save energy and be ready for anything.

Why Art Sign’s Mounting Rail Systems Are Trusted by EPCs Worldwide | Art Sign

cost-effective mounting solutions

In rooftop solar projects, EPCs often invest significant time comparing modules, inverters, and BOS pricing—yet one critical component is frequently underestimated: the mounting rail system.
In reality, the choice of rooftop rails has a direct impact on installation speed, structural risk, labor cost, and long-term project reliability. For EPCs managing multiple sites, tight schedules, and margin pressure, rail systems are not just a supporting component—they are a strategic decision.


1. Mounting Rails Directly Affect EPC Installation Efficiency
For EPCs, time on site equals cost. A well-designed Solar Racking System
can significantly reduce installation hours by:
Minimizing on-site cutting and alignment
Supporting pre-assembled or click-in clamps
Allowing fast rail splicing and tolerance adjustment
Standardized rail profiles that work seamlessly with universal mid and end clamps enable crews to move faster with fewer errors. Across large portfolios or multi-rooftop projects, this translates into real labor savings and more predictable project timelines.


Mounting Rails


2. Rail Design Impacts Structural Risk and EPC Liability
EPCs are ultimately responsible for system safety and compliance. Rooftop rails are the main load-transfer component between modules and the building structure.
High-quality rail systems offer:
Optimized cross-sections for wind and snow load resistance
Longer allowable spans, reducing the number of roof penetrations
Compatibility with certified roof attachments and local codes
In high-wind, coastal, or snow-load regions, rail performance is directly linked to project bankability and long-term risk exposure. Cutting corners on rails may reduce upfront cost—but increases structural and warranty risk for EPCs.

Rooftop rails


3. Better Rails Mean Fewer Roof Issues and Callbacks
Roof damage is one of the most common post-installation disputes in rooftop PV projects. A properly engineered rail system helps EPCs avoid these issues by:
Distributing loads evenly across the roof
Reducing point pressure on tiles, sheets, or concrete
Supporting precise alignment without forcing structures
Fewer roof issues mean fewer callbacks, fewer disputes, and better client satisfaction, especially in commercial and residential projects where aesthetics and roof integrity matter.

PV Mounting Rails

4. One Rail System, Multiple Roof Types = EPC Standardization
From an EPC operational standpoint, standardization is key.
Modern rail-based systems allow EPCs to use one core rail profile across multiple roof types by simply changing the roof attachment:
Standing seam metal roofs
Trapezoidal sheet metal roofs
Tile roofs
Flat concrete roofs
This flexibility simplifies procurement, reduces SKU complexity, and allows EPC teams to train crews on one standardized system—improving consistency across projects and regions.


5. Long-Term Reliability Protects EPC Reputation
EPCs don’t just deliver projects—they build reputations.
High-quality aluminum rails with proper surface treatment offer excellent corrosion resistance in humid, coastal, or high-UV environments. When combined with certified testing and international standards compliance, a reliable rail system:
Reduces long-term maintenance risks
Enhances system lifespan
Strengthens EPC credibility with end clients and investors
In competitive markets, these factors often determine whether an EPC wins repeat business.

7 Essential Maintenance Tips for Low Voltage Switchgear Cabinet – Extend Service Life & Reduce Faults
Do you want your low voltage switchgear cabinet to run stably for a long time? These 7 practical maintenance tips from Gaobo Power Solution will help you reduce faults and extend equipment service life.
 

The low voltage switchgear cabinet is a "heart" device of the power distribution system, and its long-term stable operation is related to the normal production and life of the whole project. However, many users ignore daily maintenance after installation, leading to aging of components, poor contact, and even short-circuit and power outage faults. According to industry data, more than 80% of LV switchgear cabinet failures are caused by improper maintenance. This article summarizes 7 essential and practical maintenance tips combined with Gaobo Power’s on-site maintenance experience, helping you standardize the maintenance process, extend the service life of equipment (more than 20 years) and reduce unplanned power outages.
 

1. Regular Visual Inspection (Daily/Weekly)

Visual inspection is the simplest and most effective preliminary maintenance method, focusing on checking the appearance and basic status of the LV switchgear cabinet, and finding hidden dangers in time.
  • Check whether the cabinet door is closed tightly, the lock is intact, and the sealing strip is not aging (to ensure the IP protection grade is not reduced).
  • Observe the indicator lights, meters and display screens for normal operation, no abnormal flashing or fault codes.
  • Check whether the wiring terminals are loose, the copper bar has no discoloration (overheating will cause copper bar discoloration), and the insulating parts have no cracks or aging.

Low Voltage Switchgear Cabinet

2. Temperature Monitoring (Monthly)

Overheating is the main cause of insulation aging and component damage of LV switchgear cabinet, and temperature monitoring must be included in the regular maintenance process.
  • Use an infrared thermometer to measure the temperature of key parts: busbar connection, circuit breaker, contactor and wiring terminals; the temperature rise shall not exceed 70K (at 40℃ ambient temperature).
  • For intelligent LV switchgear cabinet with real-time temperature monitoring, check the historical temperature data regularly, and alert and handle abnormal temperature rise in time.
  • Clean the dust at the heat dissipation port in time to ensure unobstructed heat dissipation and avoid temperature accumulation inside the cabinet.

 

3. Electrical Performance Test (Quarterly)

Quarterly electrical performance test can verify the working state of the internal components of the LV switchgear cabinet and ensure the normal operation of the electrical system.
  • Test the insulation resistance of the cabinet body and internal components with a megohmmeter; the insulation resistance of the low-voltage system shall not be lower than 0.5MΩ.
  • Check the action reliability of the circuit breaker, contactor and ATS dual power switch: simulate the on/off and switching actions, and ensure no jamming or slow action.
  • Test the protection function (overload, short-circuit, undervoltage) to ensure the protection device can trip accurately when a fault occurs.

 

4. Dust & Moisture Proof (Seasonal/Annual)

Dust and moisture are the "invisible killers" of LV switchgear cabinet, which will cause poor contact and insulation performance reduction, especially in humid and dusty areas.
  • Dust removal: Use a dry air blower (avoid water washing) to clean the dust inside the cabinet, focusing on the gap of components, busbar and heat dissipation fan; do not touch the live parts during operation (power off first).
  • Moisture proof: Install dehumidifiers or moisture-absorbing agents in the cabinet for wet environments; check the anti-corrosion coating of the cabinet body annually, and touch up the paint in time for peeling to prevent rust.

 

5. Component Aging Inspection (Annual)

Key electrical components have a service life, and annual aging inspection can avoid faults caused by component failure.
  • Check the aging degree of fuses, surge protectors (SPD), capacitors and other consumable components; replace them in time if they are damaged or reach the service life.
  • Inspect the insulation sleeve, insulating pad and other insulating parts for cracks, hardening or aging; replace unqualified insulating parts immediately to prevent electric leakage.
  • For the mechanical parts (interlock, slide rail), add lubricating oil appropriately to ensure flexible operation.

LV Switchgear Factory

6. Intelligent System Calibration (Semi-Annual)

For intelligent low voltage switchgear cabinet, the semi-annual calibration of the intelligent system ensures the accuracy of data collection and control.
  • Calibrate the intelligent meters, sensors (current, voltage, temperature) to ensure the collected data is accurate and error-free.
  • Check the communication connection of the intelligent module, test the remote control and data upload functions, and troubleshoot the communication failure (e.g., loose wiring, protocol mismatch) in time.
  • Update the firmware of the intelligent control system regularly according to the manufacturer’s prompt to optimize the system function and fix potential bugs.

 

7. Strictly Abide by Power-Off Operation Norms

All internal maintenance and component replacement of the LV switchgear cabinet must be carried out under complete power off to ensure the personal safety of maintenance personnel.
  • Form a standardized power-off operation process: power off → hang up the "no switching on" sign → check the live state → ground connection → maintenance.
  • Do not carry out maintenance work in bad weather (thunderstorm, heavy rain); avoid live operation of any parts of the LV switchgear cabinet.

 

Daily maintenance is the key to extending the service life of the low voltage switchgear cabinet and ensuring stable operation. By following the above 7 maintenance tips and forming a standardized maintenance system, you can greatly reduce the failure rate of the equipment and avoid economic losses caused by unplanned power outages. Gaobo Power Solution not only provides high-quality Low Voltage Switchgear Cabinet products, but also provides professional on-site maintenance guidance and technical training services for customers.
