Investing and transitioning to solar can seem complex but Solar Chief is here to help. Our company prides itself on educating customers on everything solar. Solar Chief wants to ensure every project is successful in producing the amount of energy needed. Faults can occur when using an online app to calculator the number of panels needed because the app doesn’t calculate all the circumstances. Solar Chief offers FREE proposals and FREE site evaluations to provide an accurate estimate.
How many solar panels is needed for your project?
Depends on the amount of electricity used and location of the panels.
How to estimate your energy needs
Energy Efficiency of Home
Make energy-saving upgrades to maximize efficiency before adding solar. Completing a home energy audit can significantly lower your energy bill. The process is not costly and many adjustments can be done yourself. Local utility companies offer energy saving tips, discounts, and rebates. SCE&G offers free Home Energy Check-ups. Below are some examples of energy upgrades.
- Inspect doors, windows, roof, and attic for leaks
- Replace your old bulbs with high-efficiency bulbs (SCE&G Discounts)
- Update to energy efficient appliances (SCE&G Appliances Recycling Rebate)
- Install energy-saving smart thermostats (example: Nest)
- Replace air filters
Assess Solar Potential and Limitation
The location of your project determines the solar potential of the solar array. PV systems use direct and indirect sunlight but the efficiency can be impacted. Look at your areas yearly sun exposure.
The limitations of your solar array can be created by shading (trees or buildings), roof conditions (age, size, material), and HOA (homeowner association) restrictions. Ask Solar Chief to provide recommendations to reach a peak efficiency of your system.
Assess Options of S
The solar option chosen could affect the number of panels in your system. Determining your use for solar energy will help configure the amount of electricity your system needs to produce. Price and ownership play a role in planning your array. Some panels can produce more electricity than others. Do you want a rooftop or ground-mounted solar system? Do you want to be connected to the grid?
Estimate Projects Solar Electricity Needs
Estimating the amount of electricity a system needs to produce is the last step. Addressing the efficiency of your home will lower the amount of energy needed to be produced. Solar Chief wants to create the most accurate energy estimation. Analyzing your power bill can determine the number of kilowatts per hour used per month. Then we will determine what your system would need to be in kW in order to meet your kWh needs.
Factors to Consider
Importance of knowing peak usage. Some homes use more energy in summer or winter and you want to have a system prepared for peak loads.
Consider any planned changes. If you will be purchasing an electric vehicle or are planning a home addition, your electricity needs may increase.
Importance of your home’s energy efficiency. If you are continuing to make significant changes to improve your home’s energy efficiency, you may need less electricity than you used in the past.
Net Metering. If you want to sell back power to the electric company, then you need to produce more power than you consume.
There is a regulatory cap on the system KW size permitted on top of your roof.
There are so many factors determining the size of your system. Contact Solar Chief to find out more. Thanks for reading!
