Off-grid solar systems for sites with no grid connection
If you don't have access to the power grid, or if bringing it in makes no sense when you could have free power instead, an off-grid solar system is the answer. We design off-grid systems with precise sizing, LiFePO4 batteries, and, when it makes sense, generator backup to guarantee autonomy at all times.
When an off-grid system makes sense
To help you place yourself, here are two typical situations:
- Sites with no grid power available. Remote farms, mountain cabins, rural telecom sites. Running the grid out to a remote location usually costs far more than generating your own power: the line is billed by the kilometer, and in hard-to-reach areas it gets complicated fast. An off-grid solar system gives you complete independence with free power.
- Specific low-consumption applications. Water pumping for irrigation or human use, powering gates, security booths, telemetry systems. They don't need the grid — they need steady, simple power.
Do you have grid access but it's very unstable, or do you want backup for power outages? In those cases what you need isn't an off-grid system but a hybrid system (grid + battery) or a backup system. We cover that on our page about batteries and backup →.
Typical applications
Remote homes and cabins. Systems that let you have electricity at all times, matched to the appliances you use.
Farms and ranches. Pumping, electric fences, refrigeration, facility lighting.
Telecommunications. Repeaters, towers, equipment shelters.
Water pumping. Direct DC systems without batteries for irrigation or human supply.
Off-grid or hybrid system?
| Feature | Off-grid | Hybrid system |
|---|---|---|
| Does it use the power grid? | No. It runs completely independently. | Yes. It combines the grid, solar panels, and batteries. |
| Does it have backup during outages? | Yes, as long as there's energy available in the batteries. | Yes, for the loads defined as priorities. |
| What happens if solar energy runs short? | It relies on the batteries or an auxiliary generator. | It can draw power from the grid. |
| Does it need more batteries? | Generally yes, because it has to cover all of the autonomy. | Generally fewer, because the grid acts as backup. |
| Can it take advantage of surplus energy? | No, it doesn't connect to the grid. | Yes, it can manage it depending on the setup and interconnection arrangement. |
| Who is it ideal for? | Properties where the power grid isn't available. | Sites with grid power that want savings and backup during outages. |
Rule of thumb: If grid power is available, even if it's unstable, it's usually best to evaluate a hybrid system first. Off-grid is reserved for places where connecting to the grid isn't possible or is simply too much.
Standalone system design
Load estimation
Every standalone system starts with a detailed analysis of your consumption: what equipment you'll use, how much power it draws, for how many hours, and at what times of day. With that balance we size the system correctly and avoid both over-sizing and leaving you without power.
Battery bank sizing
We define storage capacity based on your daily consumption, the hours of autonomy you need, the depth of discharge, system losses, and site conditions. We choose the battery technology that best fits your case, prioritizing safety, service life, and room to expand.
Complementary backup
For critical applications or sites with long periods of low solar generation, we can add a backup generator. And we automate it so it keeps your priority loads running when the battery drops below a certain level.
