Higher Efficiency of up to 18.7%

Canadian Solar CS3L-345 HiKu modules have a higher than average efficiency of 18.7%, which is achieved by a higher light absorption, innovative module design, and better shading tolerance. With a smaller cell size CS3L-345 HiKu panels are also less vulnerable to the energy losses associated with excessive heating.

Extreme Weather Resistance

Canadian Solar panels are designed to work well even under extreme weather conditions, being able to withstand heavy snow load of up to 5400 Pa and a wind load up to 3600 Pa. Operating temperature range is -40°F ~ 185°F.

Easy Mounting

Reserved mounting holes allow for easier installation. Cables are optimised to be just the right length.

High Reliability

Canadian Solar modules feature lower internal current and lower hot spot temperature, which adds to their outstanding reliability. Cell crack risk has been limited in small regions.

PID Resistant

A low annual degradation rate of 0.55% guarantees no less than 84.8% of power output by year 25.

12 Year Product and 25 Year Performance Warranty

Canadian Solar 345-watt Panel goes with an industry-leading 25-year performance warranty independently backed by Powerguard’s third-party insurance and a 12-year product warranty.

I had a very smooth experience with a1solarstore — their staff helped picking the panels and gave some advice on the installation. I picked this model because it’s cloudy around here. They barely lose power even when it’s raining.

I used the calculator to plan the system for my home. panels arrived in four days. Two were broken, but I contacted the store and they replaced the panels for me, so we are cool. It’s three months, the panels are quite powerful and I'm satisfied.

Merchandise, except for products that were specially ordered and/or assembled for the customer, may be returned within 30 days of the receipt of the product. However, there is a 15% restock fee for domestic returns. We have the right to refuse a refund, if the items are returned in a non-resalable condition.

I’m a little confused, is this for residential or commercial systems?

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.
