Are you considering switching to solar but unsure how to calculate your solar costs & returns with us? Solar energy is becoming one of the most attractive options for Irish households and businesses looking to cut bills and embrace clean energy.
Solar panels offer the advantage of reducing long-term electricity costs, lowering carbon footprints, and even increasing property value. This makes them particularly appealing for households looking to secure both financial and environmental benefits.
However, understanding the financial side such as installation costs, savings, and payback period is essential before making the investment. In this blog, we will explore how to calculate your solar costs & returns with us, explain the factors that affect your potential savings, and guide you through the steps to maximise your return on investment.
How to Calculate Your Solar Costs & Returns With Us?
When planning your switch to solar energy, it’s important to look at the individual factors that affect both your upfront investment and the long-term returns. By considering each of these elements, you’ll gain a clear picture of your potential savings and payback period.
Property Type
The type of property you live in plays a major role in solar panel installation. Detached homes usually have more roof space, which allows for larger systems that can generate more electricity.
Semi-detached and terraced houses may have less available space, but efficient solar design ensures you still get significant returns. The property type also impacts installation logistics and cost.
Number of Floors
Your home’s number of floors influences solar panel placement and energy distribution. Multi-storey houses may require additional wiring or equipment to ensure solar energy flows efficiently across all levels.

This can slightly affect installation costs, but it also ensures balanced power supply throughout the property. Our team considers these factors during your assessment, so your solar system is designed for both practicality and maximum performance.
Energy Usage Patterns
How and when you use electricity impacts the returns you’ll see from solar. For example, households that use more energy during daylight hours benefit most from immediate solar savings, while others may rely more on battery storage for evening consumption.
By analysing your energy habits, My Power provides a customised projection of how much of your usage can be offset by solar, helping you make informed decisions about system size and optional add-ons like battery storage.
Electricity Costs
Current and future electricity prices directly affect your solar return on investment. With energy costs continuing to rise in Ireland, switching to solar provides a safeguard against unpredictable bills.
The more electricity you offset with solar, the more money you save over time. At My Power, we calculate projected savings based on today’s tariffs and likely increases, giving you a realistic picture of your long-term financial return.
Project Timeline
The timeline for your solar installation also plays a role in calculating costs and returns. From initial consultation to final setup, most projects are completed within weeks, meaning you start generating savings almost immediately.

The sooner you switch to solar, the sooner you begin reducing your electricity bills. We include these timelines in your personalised calculation so you know when to expect your first returns.
Your Details
Every home and homeowner is unique, which is why personal details are key to accurate solar cost and return estimates. Factors like household size, lifestyle, energy goals, and even your future plans for the property all influence system design and payback period.
At My Power, we gather this information to provide a customised calculation, ensuring you know exactly how solar will benefit you before committing to installation.
What Are the Benefits of Calculating Your Solar Costs and Returns?
Before investing in solar, it’s important to know exactly what you’re getting in terms of savings and payback. Calculating your solar costs and returns gives you a clearer financial picture, helping you move forward with clarity and certainty.
Financial Clarity
One of the biggest advantages of calculating your solar costs and returns is having a precise understanding of how much you’ll spend and save. By seeing the projected payback period and long-term financial return, you can plan your budget effectively. At My Power, we provide customised cost and savings breakdowns, showing you exactly how solar will impact your household finances both now and in the future.
Making the Right Choice
Investing in solar is a long-term commitment, and having the right data allows you to make well-informed choices. By calculating costs and returns, you know whether solar is the right solution for your home and energy needs. This removes uncertainty and ensures that you approach the process with realistic expectations and full confidence in your decision.
Maximising Return on Investment

Every homeowner wants to see the best possible return from their investment. By calculating your solar returns, you can identify the most cost-effective system size and optional features, such as battery storage. This ensures that your money is spent wisely and that your system delivers maximum savings over time. At My Power, we customise this analysis so your system is designed with your household’s financial goals in mind.
Reducing Risk
Without calculating your solar costs and returns, you may risk underestimating expenses or overestimating savings. This can lead to disappointment or financial strain. A detailed calculation minimises this risk by factoring in electricity tariffs, your household’s usage habits, and expected system performance. This provides a realistic outlook from the start, helping you feel secure in your investment.
Environmental Impact Awareness
Beyond financial savings, calculating your solar returns also highlights the environmental benefits of your investment. You’ll see how much carbon emissions your household will offset by generating clean energy, giving you a sense of the wider impact of your decision. Understanding this adds extra value, as you’re not only saving money but also contributing to a greener, more sustainable Ireland.
Conclusion
Calculating your solar costs and returns is the most effective way to understand the true value of switching to renewable energy. By reviewing key factors such as property type, energy usage, electricity tariffs, and installation timelines, you gain a clear picture of both the upfront investment and the long-term financial and environmental benefits. This knowledge not only reduces uncertainty but also helps you make the right choice for your home and future savings.

You can calculate your solar costs and returns by considering your property type, roof size, energy usage, and current electricity rates. At My Power, we use these details to provide a tailored estimate, showing your installation costs, yearly savings, and payback period.
What factors affect my solar savings?
Savings depend on your energy usage patterns, system size, and whether you add battery storage. Rising electricity prices in Ireland also increase returns. We create a customised calculation to show exactly how solar will reduce your bills.
