Reviews of Solar Batteries and Solar Battery Manufacturers

SunPower Professionals

I was introduced to SunPower when Energy Pals as a distributor, called me and facilitated my introduction to solar energy; which I had been contemplating for a while.

Outstanding Customer Service

We've been customers for 9 years. Some of our Micro-inverters failed and we had a bit of difficulty trying to get this resolved. When I reached the correct person in the organization they went out of their way to make sure that we were satisfied customers. We love being part of green energy solutions for our planet.... read more

Best warranty, been around forever, and great reputation

The Panasonic panels we had installed had better power generation than what the competition wanted to steer us towards, and a much longer warranty.

unreliability issues

On 3rd inberter in 5 years.. have lost over 40 food solar gen days due to these crap inverters.. you will never get back 50 or 60 lost gen days.. not happy with this "cutting edge" undependiblity

Basically a scam

I ordered my roof 10 months ago. It too 4 to get installed. Now 6 months and it is still not approved. Awful Customer service

Very poor aftercare service.

Two years ago we moved to an off grid location in the Nayarit Mexico jungle. Outback USA recommended a system and battery specification for us that would be suitable in the tropics. They were more expensive than other options but we were assured that they would be fit for purpose and give us support. We built a purpose designed building to house the inverter and batteries safely. Just after a year of operation our batteries started to fail and our Mate 3S control unit on-line connection failed. We had to reduce our bank from 8 batteries to 4 batteries to keep the system working. We advised our Outback providers and service people in Mexico. After providing all the information required and constant requests for help and warranty we have been effectively ignored. We have raised this issue with Outback USA who recommended our system and again are being effectively ignored. We are in Mexico with an expensive nano carbon battery bank that is failing and unable to monitor the system on-line. We have given Outback service USA and Mexico every opportunity to communicate with us. We have been effectively abandoned.... read more

Support Lacking

I had a Schneider Electric solar monitoring system installed on my completely OTG property in 2019. Their website monitoring platform does NOT provide data regarding the power level of your battery system, which is the most important issue to monitor. I have spent months trying to get an answer or a work-around with their Service Support and I keep receiving responses via E-Mail which are NOT related to my inquiry. Additionally, it takes over a week (on average) for them to respond. Meanwhile, my battery bank and power to my home can only be monitored manually in mid-winter by trudging through snow and 20 degree weather to go to the battery shed to read the monitor.... read more

T105 deep cycle, testing Solar SAGM now

This batteries rock, last easily 3-4 years in heavy usage (discharging and charging completelly once a day), specially if you use good charger controllers. They just relased some AGM solar ones, testing them now, lets see how they go, but they claim 8 years life...

Always supersize the panels, they are way cheaper than batteries and keep batteries full all the time, also get a battery balancer that equalizes battery voltage, this helps a lot!... read more
