Consumer Reviews of Sharp USA Solar panels
No issues at all with panels
There have been no panel issues I know of since the system was installed in 2008. We have had no problems since we bought the house in 2012.
Very happy with the Sharp solar panels.

A major advantage of micro-inverters is that you can track per-panel variation over time so if a panel or inverter fails or experiences a drop in performance, you can spot it right away. Although there's no way to isolate panel performance from its inverter, in my case I knew my issues were inverter related.
For reasons explained in the inverter section below, Net Zero Solar replaced all of my inverters two weeks ago. Since then I've been tracking per-panel performance on cloudless days and I'm pleased to see less than +/-2% variation across my 24-panel array. Moreover, after six years, the average output, normalized for the daily temperature range on cloudless days, is tracking less then 3% off initial performance numbers. These stats are better than expected. So I'm very happy with my Sharp panels.... read more
Cost effective at time of installation. No problems with any modules since installation.
Our neighbors have 24 Chinese made panels and generate LESS kw each day than we do with 18 panels.
Excellent results so far, meets or exceeds expected annual KWH production.
Model is NT 175U1. No problems. Installed in Sept 2005. Still producing as much energy as when first installed. Washed once a year. 18 panels, net metering & conservative use covers total electricity needs for our duplex with 5 to 7 adults. Expected to repay investment in energy savings in 10 years. Did it in 8.... read more
3kw have performed better than expected, yielding a 35-45% reduction in my electric consumption with the grid. installed in pre incentive year of 2008, they have been removed once for reroofing and reinstalled with no problems.... read more
State of the art at the time. No discernible degradation in almost 7 years of use.
My panels were easy to install and have been performing flawlessly.
11 panels installed in 2009, no issues what so ever, production has exceeded company estimates
These modules seem to perform just like new. Only issues is the UV tie wraps holding the source circuit conductors only last 2 years and requires periodic inspection.
Additionally, we have noticed that the garage roof has some leaks where the module rack is attached. Installation over time is viewed as below average.... read more
As with any solar panels, the highest gain is yielded on a cold, clear day, and the Sharp set-up is no different. These ten panels on a tracker are grid-tied, and for the amount of time I am at this location, they not only produce enough to offset otherwise exorbitant electricity costs but also inspire me to conserve energy-use wherever I can.... read more
Panels are performing much better than expected. We were expecting to be able to produce between 65 to 75% of our requirements. Panels have been in place for 3.5 yrs and are at 100.7% since installation. We were actually contacted last year by the power company stating we had to either use more electricity or be placed in a different tariff rate (as a small producer; naturally with higher fees to them).
Panels have worked flawlessly since installation. The only maintenance I do is clean the snow off in the winter and this year for the first time, I used a mild detergent solution to clean the undersides and outer aluminum shell. (My panels are on a pole mount so I have unobstructed visibility to the entire panel).... read more
Model NT-S5E1U: not listed here, undoubtedly superceded. They're doing fine.
