Deciding to get solar energy is a big choice, but it’s more than just determining whether you want to get solar panels installed on top of your home. Another decision you need to make is how you want to be connected to the local power grid, or whether you want to be connected at all. Solar energy systems come in three options:
Today we’re going to explore some of the pros and cons of having an off-grid system.
An off-grid system is a renewable solar energy system that generates energy from solar panels during the day and stores that energy in battery backups for use at a later time. These systems are not connected to the local power grid, which means that the only available power you have is what you can generate from the panels and store in one or more batteries.
There are plenty of reasons to consider going off-grid with your solar:
While there are benefits to being off-grid, there are also some drawbacks:
To find out if an off-grid system is the best choice for you, or if there is a better option, talk to Intermountain Wind and Solar today.
Off-grid solar systems in Utah typically cost between $2.50 and $3.00 per watt installed. A 10 kW array plus a 20 kWh battery bank runs about $35,000–$45,000 before incentives. Intermountain Wind & Solar’s best cost-per-watt pricing and in-house permitting can reduce total expenses by up to 10% compared to market averages.
Customers recover 100% of their off-grid system cost in 8–12 years based on average Utah electricity rates of $0.13 / kWh. Intermountain Wind & Solar’s bulk purchase discounts and federal tax credits can shorten ROI by 6–18 months. After payback, most homeowners see net savings of $1,500–$2,000 annually.
Off-grid systems require biannual panel cleaning and annual battery health checks. Intermountain Wind & Solar’s full-time technicians perform these services in-house, inspecting wiring, inverter performance, and state-of-charge levels. Proper maintenance preserves 90% of capacity over 10 years and prevents 70% of system faults.
Battery size depends on average daily usage; most Idaho and Wyoming homes use 25–30 kWh daily. For two days of autonomy, a 60 kWh battery bank is recommended. Intermountain Wind & Solar analyzes your historic electricity bills and local sun hours to tailor capacity, ensuring 99% uptime during cloudy periods.
