Solar Kits

Discover our solar kits

Whether you are grid connected or not, with low or high electrical consumption, we have the right kit for you!

Sustainable Earth has designed a few « solar kits » to help you understand what can be done with solar systems, and mainly to benefit from new technologies provided by Victron such as « Grid Assist » or « Hybrid ». One size does not fit all, but these give you an idea of what kit provides what. It clearly shows as well the HUGE differences that can exist between two 3 bedroom homes for example: one being low energy and the other being not, and having higher electrical consumption.

Most of these kits use the « Grid Assist » technology with the existing grid as a back up used when needed. Some are completely « Off Grid » .

These kits are here to give you an idea of what can be done, for how much…  But your system is for sure unique and will have to be designed for you. As you can see when comparing similar consumptions, the best system is probably in between the less and more expensive. So contact us for your own design, based on your REAL consumption and needs.

Grid Assist

If you are grid connected and you want partial or back up alternate energy: you wish to have a back up system or an alternate energy system covering part of your electrical needs, enabling you to always have enough energy for your absolutely necessary appliances (you decide which one they are: Fridge? TV? Computer? Drill? AC? All these?…) and for your sensitive electronic equipment to stop receiving power surges from your local supplier after eventual shortages.

Off Grid

If you are « Off Grid », you are not connected to a local energy supplier. In this case you need a system which will cover all your electrical needs. The total energy produced each day will have to be more than what you use. Aas you must take into account some days with little or no sun, your system must be able to store slightly more energy to give it back to you at night and for 2, maybe 3 days without sun.
