Picking the Right Size Solar System for Your Needs
At Blue Electrics, we understand that choosing the right size solar system for your home or business is crucial to maximise efficiency, minimise costs, and ensure you meet your energy needs. Our comprehensive solar survey service is designed to help you make an informed decision. Here’s a guide to understanding the key factors involved in sizing your solar system and how Blue Electrics can assist you every step of the way.
Understanding Your Energy Needs
Analyse Your Electricity Usage
Review Past Bills
Look at your electricity bills over the past year to determine your average monthly and annual energy consumption. Pay attention to seasonal variations.
Kilowatt-Hours (kWh)
Note your usage in kilowatt-hours, which is the standard unit of measurement for electricity consumption.
Consider Future Changes
Increased Usage
Plan for any potential increases in electricity use, such as adding new appliances, expanding your home, or increasing family size.
Energy Efficiency Improvements
If you plan to make your home more energy-efficient (e.g., upgrading insulation, windows, or appliances), your future energy needs might decrease.
Assessing Your Solar Potential
Roof Space and Orientation
Available Space
Measure the available roof space for solar panels. Ensure there are no significant obstructions (like chimneys or vents) that could limit panel placement.
Orientation and Tilt
The optimal orientation for solar panels in the Northern Hemisphere is south-facing. The tilt angle should match your latitude for maximum efficiency.
Sunlight Exposure
Shading
Identify any shading issues from nearby trees, buildings, or other structures that could affect the amount of sunlight your panels receive.
Solar Irradiance
Use solar irradiance maps or online tools to estimate the average sunlight hours your location receives daily. This helps determine the potential energy your system can generate.
Calculating System Size
Solar Panel Output
Panel Efficiency
Solar panel efficiency varies by model. Higher efficiency panels produce more electricity per square meter but may come at a higher cost.
Wattage
Panels are rated by the amount of power they produce under standard test conditions, typically measured in watts (W). Common residential panels average 400W.
Battery Storage
Backup Power
If you want to have backup power during outages, consider adding a battery storage system. The size of the battery will depend on your energy needs and desired backup duration.
Storage Capacity
Battery capacity is measured in kilowatt-hours (kWh). Common residential batteries range from 5 kWh to 20 kWh or more.
Financial Considerations
Budget and Financing
Initial Costs
Calculate the initial costs of purchasing and installing the solar system, including panels, inverters, and any additional equipment.
Incentives and Rebates
Research available incentives, rebates, and tax credits that can reduce your upfront costs.
Financing Options
Explore financing options such as loans, leases, or power purchase agreements (PPAs) to make the investment more affordable.
Long-Term Savings
Energy Savings
Estimate the long-term savings on your electricity bills. A properly sized system can significantly reduce or eliminate your electricity costs.
Payback Period
Calculate the payback period, which is the time it takes for the savings to cover the initial investment. A typical payback period ranges from 5 to 10 years.
