FAQ
With top tier solar panels, you pay for the brand name, proprietary new technology, higher energy output, and better warranty support.
Please refer to the product datasheet on the product page. We have a datasheet for every product we sell.
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.
We recommend Panasonic and Mission Solar panels for smaller systems as their high energy output and excellent craftsmanship guarantee years of service.
Any of our panels can be used for a 12v system with a properly selected inverter and charge controller.
Yes, we can set up a pick up at a local distributor. Please call to discuss options and stock availability.
To achieve the best system efficiency, panels should be connected in series to create higher voltage.
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%.
We do offer discounts for orders of over 50 units. Please contact us for details.
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.
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.
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.
We do not recommend using the solar panel without the charge controller. Using solar panels without the charge controller might damage the batteries.
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.
Solar panels generally require very little maintenance. We recommend cleaning the solar panel with water, glass cleaner (Windex) and microfiber cloth.
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.
Solar panels cannot produce electricity if covered with snow.
The best direction for a solar panel to face is the South.a
Description
LONGI 355W LR4-HPB is a 120 cell solar panel, which combines high efficiency and low LID mono PERC cells. This module has a 35mm lightweight frame resilient enough to withstand 5400Pa load and 25mm hailstones at the speed of 23 m/s.
- 355W Power Output
- 120 Cell, Monocrystalline, Half-Cut Technology
- 19.5% Module Efficiency
- Low LID mono PERC cells
- 1000 Volts Max Voltage
- MC4 connectors
- Black frame, black back
19.5% Panel Efficiency
LONGI 355W LR4-HPB performs at 19.5% efficiency, ensuring greater energy yields. It shows outstanding power output in low light conditions, such as dawn, dusk and on a cloudy day, with guaranteed positive power tolerance of 0~+5W.
Quality and Reliability
All LONGI panels undergo a number of stringent quality control tests. Solid PID resistance is ensured by solar cell process optimisation and careful module BOM selection. LONGI 355W LR4-HPB is designed to withstand front side maximum static loading of 5400Pa and rare side maximum static loading of 2400Pa.
Slow Power Degradation
Slow power degradation is achieved due to Low LID Mono PERC technology. First year the panel degrades <2%, and 0.55% over the next 24 years.
Enhanced Frame Design
The module’s 35 mm frame design provides easy installation and ensures robust mechanical strength. This module passed rigorous ammonia and salt mist resistance tests.
25-Year Power Output Warranty
LONGI 355W LR4-HPB comes with a 12-year product warranty for materials and processing and 25-year warranty for extra linear power output.
