Product Overview

The Zhongtai New Energy ZT310 310W polycrystalline solar panel is engineered for reliable rooftop and ground mounted installations. It delivers a rated maximum power of 310 Wp with a panel efficiency of 15.97 percent under standard conditions. The module uses 72 high quality polycrystalline cells and durable tempered glass to ensure long term outdoor performance. A robust anodized aluminium frame supports the panel and provides excellent structural strength in varied climates. This model offers a wide power range from 300 to 330 Wp, allowing flexible array design for residential or commercial systems. Its 1000 volt system rating supports larger string lengths and reduces overall balance of system costs. The ZT310 is produced by Baoding Zhongtai New Energy Technology Co., Ltd. in China and is backed by clear product and power warranties. A 10 year product warranty covers manufacturing defects and build quality, while a 25 year power warranty supports long term energy yield. With proven polycrystalline technology, stable power tolerance, and a solid degradation profile, this module suits cost focused solar projects.

Key Benefits

Dependable 310W power output: The rated maximum power of 310 Wp helps achieve strong energy yield on limited roof space. Power tolerance from 0 to plus 1.5 percent supports consistent production across each module in the array.

Proven polycrystalline technology: Polycrystalline cells are widely used and thoroughly tested in global installations. This mature technology offers stable performance with a competitive price point for budget conscious projects.

Long term performance assurance: The 10 year product warranty helps protect against material and workmanship defects over time. A 25 year power warranty with 80 percent output retention supports long term investment returns.

Robust mechanical design: The tempered glass front and anodized aluminium frame add strong protection against wind and weather. A 3.2 millimetre glass thickness and 40 millimetre frame depth support long service life on site.

Flexible project integration: A maximum system voltage of 1000 volts supports longer strings and efficient system layouts. The panel’s 1960 by 990 millimetre footprint fits well on residential rooftops and commercial racking systems.

Consistent thermal performance: Defined temperature coefficients help predict output in real world conditions. The module operates across a wide temperature range from minus 45 to 85 degrees Celsius for diverse climates.

How It Works

This polycrystalline solar panel converts sunlight into usable electricity through an array of 72 interconnected cells. When the cells receive sunlight, photons transfer energy to electrons in the silicon structure. These energised electrons move through the cell circuits and create direct current electricity at the module terminals. In a typical system design, several panels are wired in series strings to match the input window of a solar inverter. The inverter then converts the direct current produced by the ZT310 modules into alternating current used by household or commercial loads. Excess power can be exported to the grid or sent to storage, depending on the system configuration. Performance is influenced by sunlight levels, module temperature, orientation, shading, and system design quality. The defined electrical ratings and temperature coefficients allow designers to model expected production throughout the year.

Polycrystalline cell conversion: Each cell uses multiple silicon crystals to capture incoming sunlight efficiently. The arrangement of 72 cells in series and parallel defines the module’s voltage and current characteristics at operating conditions.

Operating voltage and current: At maximum power, the panel operates around 37 volts and 8.38 amperes. Open circuit voltage reaches about 45.9 volts, while short circuit current is about 8.96 amperes under standard test conditions.

Temperature impact and stability: Module output decreases slightly as cell temperature rises above test conditions. Defined temperature coefficients for power, voltage, and current allow accurate performance estimates in hot or cold environments.

Customer Success Stories

Troy P

EG4 off-grid base kit, Happy with my purchase.

This is the first stage of my three planned purches. I got the eg4 inverter 6000 XP base kit with six 400 watt panels and the two server rack batteries. Did a little online research and followed the instructions and it got set up without any issues. Right now I'm just running it in my garage on a single outlet and have been running dual 750 watt water distillers with it. Once I get the second inverter and a bunch more panels and batteries, I plan on attaching it to my subpanel in my house that has my lights and outlets and appliances on it. Then I'll get a soft start for my AC and blower and run it on my main panel.

Jacob B

Easy Process, Genuine Support

Trying to pick the correct solar system for your needs can be very technical and frustrating. I wanted to thank Yvhan and the Portlandia Electric supply team for their patience and helpful attitudes through multiple calls. I feel like we were able to narrow it down to what worked for me and my family. My system works great and I couldn't be happier to have picked Portlandia Electric Supply.

Patrick B

Off Grid Solar Purchase

I wanted to get an offgrid solar system for years but didn’t know where to start. I found Portlandia Electric Supply on Facebook and decided to submit a quote. Within 24 hours I had a custom proposal that was almost half the price of the companies I had previously got quotes from. My wife and I decided to order online and the kit came in a timely manner and it was an easy install. Great company to work with!

James Martin

Highly Recommend

I would like to take the time to express the outstanding service that I was provided with by Portlandia Electric Supply. They provided me with all the answers to my questions, and after reviewing our quote over the phone I felt comfortable proceeding to order my kit. It’s exactly what I needed and they were there to help us over the phone when we had questions installing it. I highly recommend others in need to choose Portlandia Electric Supply.

Solar Kit for Mobile Work Van

As a professional videographer, I needed reliable power on the go.Portlandia Electric Supply Delta Pro and roof-mounted panels were the perfect solution. Setup was easy, and the kit included everything needed. The Delta Pro powers my cameras, lights, laptop, and a small fridge with impressive battery capacity.

Keith S

Best Tech Support

You folks have been wonderful guiding me through the ins and outs of going solar. Plus your tech guys Rod and Nelson are the absolute best. They explained all the different aspects of inverters, batteries and how to keep them in top condition. Too much more to put here… but no other company has the 100% tech support you provide for your customers!

Coll A

Great Experience

My experience with Portlandia Electric Supply has been excellent. Before the sales, they answered all my questions to assure that I got what I needed. After the sales they continued to support me with answers and help. I had a warranty issue with a unit, and it was handled as well as possible. I would recommend them to anyone looking to go solar.
