How to Calculate Your Savings and Costs with SPV’s Solar Calculator?

by Liz Martin | Jan 24, 2025

Are you considering installing solar panels but unsure how to calculate your savings and costs with SPV’s solar calculator? Solar energy is becoming an increasingly popular choice for homeowners and businesses in Ireland due to its potential to significantly lower electricity bills and reduce carbon footprints.

Solar panels provide the benefit of utilising a free, renewable energy source while offering energy independence and long-term financial advantages. This can be particularly valuable in a time of rising energy costs and growing environmental awareness.

However, understanding the financial aspects of solar energy is crucial for ensuring you choose the right solution. In this blog, we will explore how to calculate your savings and costs with SPV’s Solar Calculator, break down the key factors that influence these estimates, and provide tips for optimising your solar energy investment.

How to Calculate Your Savings and Costs with SPV’s Solar Calculator?

Determining your solar savings and costs is straightforward with SPV Energy’s user-friendly Solar Calculator. Built for accuracy and ease, it guides you through key steps to deliver customised results for your property.

Step 1: Identify Your Property Type

Begin by selecting the type of property that best describes your home. Options include semi-detached, detached, terrace, or duplex. This step allows the calculator to determine the best solar system configuration for your property.

For instance, detached homes often have more roof space, allowing for larger installations. Terrace or duplex homes may have unique constraints that the calculator will factor into its recommendations. By identifying your property type, you ensure that the system suggested is both practical and efficient.

Step 2: Specify the Number of Stories

The number of stories in your property—whether it’s a single-story, two-story, or three-story home—affects the placement and efficiency of your solar panels. Multi-story homes may have larger roof areas on different levels, which could impact the overall design.

Single-story homes, on the other hand, often benefit from a more straightforward installation process. This detail also helps estimate potential shading and energy production. Providing accurate input ensures the best-fit solar solution for your property.

Step 3: Input Your Monthly Electricity Bill

Provide your average electricity bill to calculate potential savings. You can enter the amount manually or opt to use the national average if unsure. Your electricity bill is a critical indicator of how much energy your household consumes.

This data helps the calculator estimate your potential savings by comparing your current costs with the expected reductions after solar installation. The more precise your input, the more accurate the savings estimate, helping you better understand the return on investment.

Step 4: Select Your Peak Usage Time

Let the calculator know when your home is most active: morning, afternoon, evening, or throughout the day. Peak usage times affect how much of your energy consumption can be offset by solar production.

For example, homes most active during the day can maximise savings by directly utilising solar power generated at that time. Evening-heavy usage may require additional considerations, such as battery storage. This step ensures that the system proposed is customised to your unique energy usage patterns.

Step 5: Determine Your Roof’s Orientation

Choose the direction your roof faces—north, south, east, or west. Since south-facing roofs typically maximise solar efficiency, this step is crucial for accuracy in savings predictions. The calculator uses this information to estimate how much sunlight your panels will receive daily.

For non-south-facing roofs, it considers adjustments to ensure optimal performance. Understanding your roof’s orientation allows you to make realistic predictions about energy generation and cost savings.

Step 6: Set Your Project Timeline

Indicate when you plan to start your solar PV project: ASAP, within 3 months, 3-6 months, or beyond. This timeline allows SPV Energy to prioritise your needs and provide timely support. Early planning can help you take advantage of potential grants or incentives.

For those in a hurry, immediate scheduling ensures quick installation and faster savings. By providing your timeline, you align your project goals with SPV Energy’s customised services.

Step 7: Receive Your Free Solar Savings Report

After completing the above steps, enter your details to receive a personalised solar savings report. This report includes detailed estimates of your energy production, savings, and return on investment.

Alongside the report, you’ll receive a free, customised quote customised to your property and energy needs.

Frequently Asked Questions

How does SPV Energy’s Solar Calculator estimate my solar savings?

The calculator assesses your property’s characteristics, such as type (semi-detached, detached, terrace, or duplex), number of stories, average monthly electricity bill, peak usage times, and roof orientation. By inputting this information, it provides a customised estimate of potential savings and system costs customised to your specific circumstances.

What if I don’t know my exact monthly electricity bill?

If you’re unsure of your average monthly electricity bill, the calculator offers an option to use the national average. This feature ensures you still receive a reliable estimate of potential savings and system costs, even without precise billing information.

How does my roof’s orientation affect the calculator’s estimate?

The direction your roof faces (north, south, east, or west) significantly impacts solar panel efficiency. South-facing roofs typically receive the most sunlight, leading to higher energy production. The calculator incorporates your roof’s orientation to provide an accurate assessment of potential solar output and savings.

Can the calculator accommodate different property types and sizes?

Yes, SPV Energy’s Solar Calculator is designed to handle various property types and sizes, including semi-detached, detached, terrace, and duplex homes. By specifying your property’s characteristics, the calculator customise its recommendations to suit your unique energy needs and structural considerations.

How does the calculator factor in my energy usage patterns?

By selecting when you use your home the most (morning, afternoon, evening, or all day), the calculator adjusts its estimates to reflect your specific energy consumption habits. This ensures the proposed solar system aligns with your lifestyle, maximising efficiency and savings.

What are the next steps after using the Solar Calculator?

After receiving your customised solar savings report, you can contact SPV Energy to discuss the details further. Our team will provide a free, no-obligation quote and guide you through the process of switching to solar energy, ensuring all your questions are answered and your needs are met.
