How to Choose a Solar Power System
There are three main types of solar energy systems: grid-tied, grid-tied with battery backup (hybrid), and off-grid power systems.
To find the right solution for your family, it’s important to assess your need and energy usage habits.
If you still have questions after reading the information below, please get in touch and we’ll be happy to walk you through the decision-making process.
Grid Tied Solar Power Systems
- Least cost
- Easiest design
- Minimal components
- Virtually zero maintenance costs
- Shutdown during a power outage
- Lowest return on investment
- Does not produce power during the daily peak demand
- Highest overall carbon emission option
- Monthly power bill from the POCOS
Grid Tied Solar Power System with Battery Backup (Hybrid)
A hybrid grid tied solar power system is connected to the power grid, but also adds battery backup to your system. The addition of a battery backup enables the system to balance production and demand, therefore protects against power outages.
Solar electric system production depends on the available sunlight. Moreover when sunlight is abundant, production can exceed demand. Whenever this happens, excess power charges your batteries. Sometimes the system is producing less electricity than demanded by the home, the batteries can make up the shortfall.
Grid tied systems being connected to the utility power grid. Allowing the homeowners to draw from the grid during periods of excess demand and to sell power to the grid when there is excess production.
A hybrid system allows homeowners on time of day metering to utilize their own power during high demands, thus saving on peak charges. A hybrid system can also be integrated with a standby generator.
While hybrid grid tied systems offer more flexibility, they are not without their disadvantages. Charging and discharging batteries reduces the overall efficiency of the system, meaning these systems are more complex and more expensive.
- Electrical power available during grid outages
- Peak usage draws can be controlled
- Will allow excess energy to be sent into the power grid
- Higher initial cost
- Requires a battery bank
- Requires maintenance
- Medium carbon emission option
- Monthly power bill from the Power Companies. (POCOS)
Off-Grid Solar Power
- Requires less solar panels than the other options
- No monthly charges, or time-of-day usage fees
- Greenest of all the options; low carbon emissions
- No monthly POCOS billing
- A larger battery bank often required
- Has more expendable components
- Requires monthly maintenance
- Additional personal labour required
