How do they do in hot weather

A1 SolarStore

Good temperature coefficient of about -0.35%/°C. They lose less power in summer heat than many panels. Actually perform better in cool weather, which is great for spring/fall peak production.

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%.

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

About product

Imperial Star Solar ISM7-SHDD108-405M is a PV module fit for both residential and commercial applications. Imperial Star Solar engineers made the Atlas PERC 182MM series durable and efficient while minimizing the amount of useful space required for their operation. 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. ISM7-SHDD108-405M 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. Not surprisingly, the efficiency of this module is quite high – 20.7%. The innovations made the panel's appearance as impressive as its specs. A mere 1.18" thick, this model is completely black with a smooth surface. This beauty doesn’t compromise the quality or reliability of the panel. Imperial Star Solar offers a 25-year product warranty and guarantees 84.08% of original performance after 25 years of operation.

High efficiency of 20.7%

Imperial Star Solar Atlas PERC 182MM panels have a high efficiency of 20.7 percent and take full advantage of the company's technologies, which have won Imperial Star Solar several honors. This PERC option produces more electricity per square foot of PV modules. This translates to shorter installation times and fewer clamps and racks. All of this lowers your overall expenditures and shortens the payback period.

Keeping cool in hot weather

Even at high temperatures, ISM7-SHDD108-405M remains efficient. It loses just -0.35% efficiency for every 1.8°F over 77°F, letting you make the most of the sunniest hours.

Quality and reliability

ISM7-SHDD108-405M receives multiple quality checks throughout the manufacturing process and is subject to stringent quality and reliability testing. The manufacturing facilities are highly automated, eliminating the risk of human error. Imperial Star Solar is dedicated to quality, safety, and reliability to ensure you get the very best.

Reliability and degradation resistance

Imperial Star Solar guarantees slow deterioration over the next 25 years. The performance will decline by no more than 2% during the first year and then by no more than 0.58% every year after that. After 25 years, your modules will retain at least 84.08% of their original performance. This 405 W Imperial Star Solar panel also comes with a substantial 25-year product warranty.

A panel that can handle hail, wind, and snow

This module is weatherproof due to the 1.18" frame manufactured from black anodised aluminium and a layer of safety tempered glass.

Outstanding all-black design

The panel has a sleek, all-black style that complements any roof beautifully. Imperial Star Solar uses unique treatment and selection procedures to guarantee optimum cell color. The cells are connected by thinner wires, and from a distance, the surface of the modules seems seamless and smooth.
