About product

Silfab SIL-490 HN is a PV module created for large and small commercial applications. Silfab engineers made these panels durable and efficient, while minimizing the amount of useful space required for their operation. One of the keys to making these panels ideal for commercial use is the half-cut cell technology. The SIL-490 HN 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.

The efficiency of this model reaches 20.9% – well above the market’s average. The robust silver frame can easily handle even the strongest winds and heaviest snowfalls. The rear of the panel is ready for loads up to 2400 Pa and the front for up to 5400 Pa. The warranties provided by Silfab are also among the best in the industry. The 12-year product warranty is extendable to 25  years, and the linear performance warranty lasts three decades.

The actual power output is comparable to what was stated. There hasn't passed enough time to say much else about the system. As for A1, I can honestly say that I have seldom had such a positive experience dealing with a firm in any industry. Authentic experts!

The panels have performed admirably and effectively. An attractive option for a large system. The cells are not checkerboard blue, but black, it's a pro for me.

Does this panel have built in inverter ? If no do you sell them.

No, it doesn't. But you can find solar inverters here:
is your permanent mount 490 watt solar panel Compatible with a 500 watt portable power station?

This solar panel comes with standard MC4 connectors which a power station should support. Still, make sure this is the case, there are many models out there.
Can I connect these with Anderson interface cable into my solar generator?

Depends on the specs of your generator. If it supports the wattage and voltage of the panels, as well as the standard MC4 connectors, they should be compatible.
