My test is totally coherent with yours words bellow your 28w street light have a good
performance, better performance that a ZNZ similar unit
Comparison at 5m:
LUX VOLTAGE CURRENT POWER
Sumaster 28W (28 led) 60 12,35 2,9 35,8 w
ZNZ 40W (32 led (32x 1.1w led) 59 12,4 3,8 47 w
is clear, sunmaster deliver the same light, with less power, why? I gues that maybe you use more powerfull leds, then they work in a more eficient range,... I am learning with you
Thank you for your follow up of the solar system I purchased from you. Yes, I configured and installed the system myself, with the help of my roofer for the racks and panels, and it has been working great since the end of November 2010
[2013-10-9 16:17:45] demetrios: The pictures I sent you
I'd the site by night at far distance
[2013-10-9 16:18:56] Lily : ok,is it bright enough?
[2013-10-9 16:19:51] demetrios: yes,very Good
Installation of your lights
Remarks: we used the wire 10 AWG between batteries and controller. The batteries are located at 3 feet under
ground. The concrete cover is located at one foot under ground. The Cover is sealed with cement and sand. After, we
put sand and ground to finish.
The Installation of the lamp is at the main entrance of a farm of game birds (ducks, guinea fowl, and wild turkeys). The
second is located at the main entrance of a Foundation.
The light is very well. Congratulations at SUNMASTER.
Chile Javier: I must compete with these ,some people only see the price here
Lily yao: I know,even some middle east customer said 0.35,I think maybe
they not give full power
Chile Javier : I never buy the cheapest Lily. Cheapest is dangerous,past year I bought a PV panels sample from Jiangsu,cheaper,but thinner
and lighter than Yours,therefore fragile
Im fine Allen, thanks for ask,my customer is very happy,
with your lamps because,its working fine and has,a very good quality , now,they ask for the 60 watt?smodel, ?do you have this
kind? ? it has the same price?
GOOD MORNING Linda.
Thank you so much for your help and support about
solart street light.Sunmaster,you are the best.
I WANT TO LET YOU KNOW THAT WE MADE
A TEST TO SOLART STREETLIGHT . IT WAS
ON LAST NIGHT AT 8:35 PM WHEN IT STARTING DARK
AND TURN OFF ABOUT 6:30 AM. IT WAS WORKING
PROPERLY AS YOU SAID
IN YOUR SOALRT STREET SETTINGS
My Solar Pump is ," The Best Thing Since Canned Beer! It was designed for 14 GPM. It is Pumping 16 GPM!. Pumps all day from Sun up to Sun Down! Everyday! Even when it overcast it is producing. Attached is some pictures for your website!
You guys are great I enjoyed working with you and trust your service and will continue doing business in the future.
I have attached a few photos as well as a screen shot from Enlighten to show the energy production. Since I brought the system on line in September, the graph has trended down, but it is starting to trend back up as the days get longer and weather gets nicer. I am very happy with the system and I am very happy with the service that you and SunMaster Solar provided. Installing the Solar panels myself was both fun and rewarding. The system has outperformed the predicted CSI output over the four months it has been in operation. Given that performance over the shortest days of the winter, I am excited to see what the system will do over the coming spring and summer. I plan to leave the panels at the PG&E recommended fixed tilt for one year and then I will adjust the tilt quarterly the next year to see how the performance compares.
The installation went fairly smoothly, and we were final’ed out and up and running within 5 days (should have been 4). The only hiccups were the stickers and the power company. We ended up having to have some exterior stickers mad, and then used a connection at the Chamber to pressure NV Energy to expedite our net meter request because some bureaucrat was going to sit on it for 10 days before installing it.
The latter issue was the most frustrating part of the project; and I would have expected NV Energy to embrace these matters. Oh well.
The Envoy powered right up, saw all of the inverters, and the data output and website are fantastic. Shadowing has a minimal effect early morning and we generate about 5000W on a clear day; this might go up in the summer. It appears as though the output will be limited by the inverters and panels to about 200w max per, which is consistent with the Enphase literature.
We lucked out with the trusses setting within 2 inches of the roof tile dish, so the hooks and rails set quickly. I noticed some left and right offset tile roof hooks in the literature, which could have been used if the trusses were further off, but they were side mount. The roofers really liked the ease of the hook installation with minimal grinding on the barrel profile tiles.
The rack system on our patio cover went together pretty easy, and pre-packaged components would not have worked. I am thinking of adding an additional 8 panels on the east roof to max out the system. I will send you the part list in a few weeks.
Thank you very much for your patience and assistance in working with us on this system.

It was a pleasure working with you and SunMaster Solar on the installation of our home solar system. As homeowners doing the project ourselves, it was extremely helpful to have you on the other end of the phone line providing us with guidance and information needed to enable us to have a successful installation. We so appreciated your follow up, attention to detail and ability to answer our technical questions.
Thank you again for helping us with our solar installation.
Allan and Sherry
“Through SunMaster’s quality service and leading edge LED lighting solutions we have achieved a significant reduction in our energy bills and carbon emissions. All staff at the factory have noticed a great improvement in the lighting and feel the benefit of a better working environment. We are looking forward to working with SunMaster on further LED lighting projects.”
