How to Calculate Your Potential Solar Savings.
Introduction to Solar Savings
Solar energy offers an exceptional return on investment for homeowners, businesses, and institutions alike. Beyond its environmental benefits, solar energy provides a financial solution that grows more appealing each year. At Trogon Energy, we believe in empowering customers with the knowledge and tools to make informed energy decisions. By going solar, you’re not only protecting the environment but also creating significant long-term savings. Here’s a step-by-step guide on how to calculate these potential savings to help you evaluate if solar is the right choice.
Understanding Solar Savings Components
Solar savings are influenced by several key factors, which are important to consider for an accurate calculation. Here’s a breakdown:
i) Upfront Costs: This includes the cost of solar panels, inverters, batteries (if opting for a storage solution), and installation. While solar systems have a significant upfront cost, they provide financial payback over time. Trogon Energy provides detailed, transparent pricing to help you understand exactly what you’re investing in.
ii) Maintenance Costs: Solar systems typically require minimal maintenance, mostly cleaning and periodic checks. Since panels generally have a lifespan of 25 years or more, maintenance costs are minor compared to traditional energy sources.
iii) Reliability Amid Power Shortages: Zimbabwe faces frequent power cuts and load-shedding. Investing in solar offers reliable access to electricity, allowing households and businesses to avoid disruptions and improve productivity. Solar systems with battery backups are particularly valuable in this regard.
Key Factors Influencing Savings
The following factors impact the total savings you can expect from solar:
- Electricity Rates and Inflation: As utility rates increase, so does the value of generating your own energy. Solar allows you to “lock in” energy costs and avoid future price hikes, making your investment more valuable over time.
- System Size: Savings are directly proportional to the system size, so larger systems that meet most or all of a building’s energy needs will provide greater savings. Our experts at Trogon Energy help determine the right system size based on your energy use and property constraints.
- Sunlight Exposure and Location: Solar panels perform best with direct sunlight, which is affected by factors like geographic location, roof orientation, and shading. We conduct an on-site analysis to ensure your system is optimized for maximum sunlight exposure.
- Net Metering or Grid Interactions: Net metering programs allow solar users to receive credits for excess energy sent to the grid, which can further boost savings by offsetting energy costs. If net metering is available in your area, it’s an excellent way to increase the financial return on your solar investment
How to Calculate Savings in Four Steps
Calculating your potential solar savings involves comparing your current energy costs with estimated solar production and costs. Here’s how to do it in four steps:
Step 1: Determine Current Energy Usage
Start by reviewing your electricity bills over the past year to find your average monthly or yearly energy consumption in kilowatt-hours (kWh). Knowing this figure is essential to sizing a solar system that matches your needs.
Step 2: Estimate Solar Production for Your Location
Trogon Energy uses sophisticated tools, such as PV Watts or in-house solar calculators, to estimate how much energy a solar system would generate based on your location and available sunlight. For example, in sunnier regions, a 5kW system may produce an average of 6,000 kWh per year, offsetting a significant portion of your annual energy costs.
Step 3: Compare Monthly/Yearly Solar Production with Energy Needs
Once you know how much your system can produce, compare it with your current energy consumption. If your system covers 80% of your annual usage, you’ll be able to cut your electricity bill proportionally.
Step 4: Calculate Payback Period
The payback period is when the initial investment has been covered by savings. To find this, divide the system’s total cost by your yearly savings. For example, if your solar installation costs $10,000 and you save $1,500 per year, your payback period will be approximately 6.7 years. Once past this period, your savings are “pure profit,” and the system will continue to provide free energy for many years.
Case Study Example: Small Commercial Installation
This example demonstrates the benefits of a smaller solar system designed for a business with high energy consumption during daylight hours. Here’s a breakdown of the system and savings:
- System Cost: $6,000 for a 3kVA system
- Estimated Annual Production: 4,500 kWh
- Annual Savings: $1,400 in electricity bills
- Payback Period: 4.3 years (after which the system will provide energy at no additional cost)
In this scenario, the business benefits from a short payback period of just over four years. With reduced reliance on the grid and increased energy independence, this system continues providing value well beyond the initial payback period.
Additional Benefits of Solar Beyond Savings
–Increase in Property Value: Properties with solar installations are valued higher, as buyers are increasingly interested in energy-efficient homes and reduced utility bills.
–Energy Independence: By generating your own power, you’re less reliant on the grid, which is particularly advantageous in areas prone to load-shedding or frequent blackouts.
– Environmental Impact: Solar energy is a clean, renewable resource, and by adopting solar, you’re contributing to a reduction in carbon emissions and supporting a healthier planet.
