If you are considering a battery for a cottage in Collingwood, sizing is the first decision. The Ontario Energy Board sets electricity prices each November 1, and knowing your options for energy storage and solar helps you choose a system that fits your needs. Muskoka Energy Storage is a referral service: we pass enquiries to an independent local solar and battery storage installer who can design a system around your energy use.
Understanding Your Energy Needs in Collingwood
Before you can accurately size a battery for your cottage, you need to understand your energy consumption patterns. This includes evaluating how much electricity you use on a daily basis, particularly during peak hours. On the Ultra-Low Overnight (ULO) plan, the highest rate is 37.7¢/kWh from 4 PM to 9 PM on weekdays (Ontario Energy Board prices in effect November 1, 2026).
To get started, consider conducting an energy audit of your cottage. This audit should include:
- Identifying all electrical appliances and their wattage.
- Tracking your energy usage over a week or month.
- Calculating your peak usage times, particularly during weekends or holidays when cottages are frequently occupied.
Once you have a clear picture of your energy needs, you can better assess how much battery capacity you will require to ensure you have enough stored energy to cover your usage, especially during peak rate hours.
Battery Capacity: What to Consider
When it comes to battery capacity, a good rule of thumb is to size your battery based on your highest daily energy consumption. For example, if your cottage uses 30 kWh of energy on a busy weekend day, that figure is a starting point for the installer, who will also look at which circuits you want backed up and how much of the load solar can cover.
Battery systems are typically rated in kilowatt-hours (kWh). Therefore, if you plan to install a new solar system alongside your battery for HRSP rebates, you should also consider how much solar power you can generate. The size of the solar array affects the battery size you need. Solar produces the most on long, sunny days and much less in winter, so ask the installer to estimate production for your roof.
Choosing the Right Battery Technology
There are several types of battery technologies available for energy storage, including lithium-ion, lead-acid, and saltwater batteries. Each has its advantages and disadvantages: lithium-ion batteries are known for their efficiency and longer lifespan, while lead-acid batteries are typically cheaper but have a shorter life and lower cycle efficiency.
For cottages in Collingwood, lithium-ion batteries are often recommended because they are designed for frequent charging and discharging; check the manufacturer's warranty for capacity and years. This makes them a suitable choice for seasonal use, as many cottage owners may only use their properties during certain times of the year.
Calculating the Cost of Battery Installation
When planning for battery installation, it’s essential to factor in the costs associated with both the battery and the required solar installation. Under the HRSP, you can receive up to $5,000 for battery storage installed together with new solar. Rebates are capped and cannot exceed a share of the project cost.
The solar installation can qualify for up to $5,000 as well, for up to $10,000 combined. Taking the solar rebate means giving up net metering for the life of the system, so ask the installer whether the rebate or net metering comes out ahead for your home.
Check Save on Energy for the current amounts and rules before you rely on them, including any approval needed before installation. Beyond the rebate, the cost depends on battery capacity, solar size, the electrical work and the site, so an installer quotes after seeing the cottage.
The main things that drive the cost:
- Battery capacity and chemistry
- The size of the solar array
- Electrical work, such as a panel upgrade or long wiring runs
- Site access and where the battery can be mounted

The best battery size depends on your cottage's energy needs, which circuits you want backed up and how much solar you add. As an example, a battery for a few essential circuits might be around 10 kWh, while heavier use could call for 30 kWh or more; an installer can size one from your actual usage.
No. The HRSP battery rebate is only available when the battery is installed together with new solar. A standalone battery, or one added to existing solar, is not covered.
Track your energy consumption over a week, noting when your usage is highest. This data will help you size your battery accordingly.
