Off Grid Solar System
Unlike many other solar suppliers NGSW Group does not have any particular bias toward system hardware. Technology is changing so rapidly but, here are just a few pointers that most customers would not be aware of.
Off Grid Solar System Kit1. There are many panels promoted as Tier One (which is represented by the top 2% of panel manufacturers) but many of these have since slipped back into the Tier Two zone as newer panels come on to the market. Distributors do not change their marketing to reflect this.
2. Some panels work better in different climates, some technologies can be affected by external influences so there is no “best panel”. Many solar companies labour the point about offering the “best panel” but that is probably because the panel they are pushing is on special. There is, however, “best solution” for wherever you are. |

3. Warranties. Customers need to know just how warranties work. For instance, a product warranty represents the time the manufacturer or the manufacturer’s agent will honour a replacement in the event of failure. Once the item has been replaced the warranty does not start again rather the term of the original warranty is maintained. So, if a product fails after 7 years and there was a 10 year warranty, when it is replaced you only have the residual 3 years warranty on the replacement product.
There is also no such thing as a 25 year performance warranty on solar panels. This is simply a guarantee that the panel will perform up to Australian standards. There is no provision for you to claim in the event the panel fails to perform accordingly. And, warranties may not cover the removal and replacement of faulty hardware. Labour costs to do this can be very expensive so it is critical you are made aware of just what is and isn’t covered in your warranty provisions and ensure you see this in writing. This is the same for all grid system, on grid solar kits, off grid solar kits and solar airconditioning, |
4. There are competing inversion systems.
a. The standard string inversion system is fine for most situations but the moment one or more panels can become compromised by light or damage it will affect the entire string. b. Micro inversion isolates each panel producing AC current on the roof but is expensive and has limitations when interfacing with batteries. This technology is newer than standard string systems but older than optimisation. c. Optimised systems are ideal for shaded areas as they also isolate each panel. Optimisation is the newest technology and offers the most robust warranties. |
KEY ISSUES
|
The key issue in choosing and combination of panels and inverters is Warranty and the quality of the company backing and supporting those warranties. If the manufacturer does not have a substantial base in Australia the warranties are virtually worthless.
No Grid Solar will only deal with hardware suppliers where the manufacturer has a substantial base in Australia, where the product warranty of a panel is a minimum of 15 years and where the warranty of an inversion system is 12 years. And No Grid Solar will offer 10 year free monitoring on every system it sells (on grid solar systems, hybrid solar systems or off grid solar kits) for your peace of mind. |
