Products
Panels are usually delivered by the pallet within the solar industry, so when purchasing individual panels they will not come boxed.Â
Over 80% of the solar panels we retail are second-life or warehouse seconds. This means that availability of specific panels is unpredictable.
Stock levels listed on the website reflect real-time availability and if levels are lower than your requirements, your best option is to choose a different panel. It could be six months, a year, or we may never receive more of a particular panel.
Second-life panels have been used in a prior application (such as grid-tied rooftop PV) but have been removed with plenty of life left in them. We believe these high-performance products should fulfill their complete functional lifecycle. Panels arrive cleaned and assessed and we provide a five-year warranty because we are confident of their capabilities. 


Warehouse seconds are panels that never made it to their intended application. They have never been pointed at the sun, but may have been shipped around or sat in storage for some time. 

Yes… but it is not straightforward and you really need to know what you’re doing. Having matching panels is most ideal and our team can help you find something that best meets your needs.
We have a Tech Talk that delves into this a little deeper if you want to understand the complexities of mixing panels.
You need a contingency plan just in case anything goes wrong. For example, unexpected bad weather can result in lower solar production which may not meet your power needs. There is always the possibility of some kind of unexpected event or fault even in the best planned system.
Alt-Tech are not responsible if an appropriate contingency plan is not put in place.
This depends on your unique set-up.
If you are planning a new system, think ahead about if you may wish to add on at a later stage and let us know up front.
If you are looking to add to your system, get in touch with our team and we can advise if this will be possible – Contact Us.
