About product

SIL-500-HM is part of the Silflab Commercial Series — optimized for commercial projects where maximum power density and superior performance is essential. These panels employ cutting-edge technologies to achieve superior efficiency and reliability. The Passivated Emitter Rear Contact (PERC) technology ensures excellent power output. This solar cell type employs an additional reflective layer to absorb more sunlight.

Another advantage is the half-cut cell technology. SIL-500 HM has solar cells half the size of those installed in conventional panels. The main benefits are decreased power loss, improved longevity and better low-light performance. Given its size and weight, SIL-500 HM efficiency of 21.0% is quite impressive. Silfab provides 25 years of product warranty and guarantees that after 30 years, performance will be at 82.6% or more.

More power and efficiency

An already high efficiency of 21.0% is further enhanced by PERC technology. By adding a solid PID resistance and special glass lamination on top, the manufacturer ended up with an efficient and very durable model. Under standard test conditions, SIL-500-HM outputs 500W of power.

Better performance at high temperatures

Excellent temperature coefficient means more energy as temperature rises. Every 1.8°F hike above 77°F will decrease your panel’s efficiency by only -0.36%.

High quality standards

Silfab's strict manufacturing standards include multiple tests to provide extreme quality assurance. The facilities are highly automated, allowing the company to maintain high standards and keep the level of warranty claims very low.

Low degradation for increased lifespan

The amount of power output loss experienced by these panels during the first year of operation will not exceed 2.9%. The average yearly power drop from the second to the 30th year will not surpass 0.50%. After 30 years, the module will still produce more than 82.6% of its initial output.

A panel that can handle hail, wind and snow

The 1.37" frame built of anodized aluminum and a layer of protective tempered glass make this module weather-resistant. The front side of the modules can withstand a 5400 Pa load, whereas the back side can withstand a 2400 Pa load.

We bought 100 of those for a project in Texas. Even though it was a big order, A1 team handled the order very professionally. Thanks!

I had no idea which solar panels would be best for my home and felt completely overwhelmed. thankfully, your team stepped in and provided expert recommendations. they helped me weigh the pros and cons of each option and guided me to these in the end.

Snap! That was so seamless a process. Normally solar supply stores want to sell pallet loads of panels. Just wanted one over my boat cockpit. Still treated me like it was a big order. Tatiana was awesome. Thanks so much!

Generally, it can. However, according to the paragraph C clause 6 of the Silfab Limited Product and Linear Performance Warranty as of September 14, 2021: "The Limited Warranties do not apply if the Product has been installed or subject to use in a location that is within 5 meters of a saline water body or the Product, in Silfab’s absolute judgement, may otherwise be subject to direct contact with salt water (including without limitation as a result of immersion, waves or salt spray)".

Is this compatible with the Bluetti AC 500?

No. For AC 180 only 400W panels would work

FAQ

How much is shipping and how long is delivery?

Our standard shipping charge is $250 for up to 11 panels and it is increased by $25 for every 4 additional panels. In the event, the product is only available on East or West coast custom quote will be sent to you before the order is processed. Normally, we are able to deliver solar panels within 7 business days.

What is the difference between low price panels and top price panels?

With top tier solar panels, you pay for the brand name, proprietary new technology, higher energy output, and better warranty support.

What are the dimensions of the panel?

Please refer to the product datasheet on the product page. We have a datasheet for every product we sell.

How long is the warranty on the panel?

In general, manufacturers provide a 25 year-long performance warranty and a 10 year-long equipment guarantee. Some manufacturers offer 12-15 years of warranty. More information is available in our warranty support section.

Which panels do you recommend for RV, marine?

We recommend Panasonic and Mission Solar panels for smaller systems as their high energy output and excellent craftsmanship guarantee years of service.

Can this panel be used with a 12v system?

Any of our panels can be used for a 12v system with a properly selected inverter and charge controller.

Can I pick up this panel from your fulfillment center to save on shipping?

Yes, we can set up a pick up at a local distributor. Please call to discuss options and stock availability.

How do I connect these panels?

To achieve the best system efficiency, panels should be connected in series to create higher voltage.

How many panels do I need?

This number is determined by your average energy needs. Depending on the type of panels and energy consumption, you might need anywhere from 12 to 45 solar panels. Remember, the more panels you install the more energy you will get.Please use our solar calculator to estimate your energy consumption and plan on building a solar system that will exceed your energy needs by 25%.

Do you offer discounts?

We do offer discounts for orders of over 50 units. Please contact us for details.

How do I build a solar system?

Please use our solar calculator to estimate what equipment you need. Choose your panels, microinverters, inverters, and solar batteries if necessary.Please note that we do not offer solar system design or installation.

How do solar panels compare?

Solar panels differ by power output, voltage, connection type, size, efficiency, and weight. Some solar panels might be sold together with microinverters as a set.

Can I build a solar system by myself as a Do It Yourself project?

Yes, it is possible if you understand what solar equipment you need and how to connect it together. However, please be mindful that handling your own electrical work without having proper experience might cause life-threatening injuries. Please contact a certified electrician if you do not possess appropriate electrical skills.

Can I connect and charge my solar panel battery directly with the solar panel?

We do not recommend using the solar panel without the charge controller. Using solar panels without the charge controller might damage the batteries.

Can I drill holes into the aluminum frame for mounting?

We do not recommend drilling any new holes to the aluminum frame of the panel as it could damage the internal circuit and solar cells. (Also, any modification to the panel will void the warranty). We recommend only using the pre-drilled holes for mounting.

Do solar panels require maintenance? Can I wash my solar panel?

Solar panels generally require very little maintenance. We recommend cleaning the solar panel with water, glass cleaner (Windex) and microfiber cloth.

Will my panel produce power in an overcast condition?

While solar panels require sunlight to generate solar energy, they will still work in cloudy weather. Even on a cloudy day, solar panels will produce energy just not as much.

Will my panels produce power if covered with snow?

Solar panels cannot produce electricity if covered with snow.

What is the best direction for a solar panel to face?

The best direction for a solar panel to face is the South
