Calculating solar panel costs, savings, and energy output can be a bit complex, considering several variables. That's why we've created our solar panel calculator, a user-friendly tool designed to help you quickly estimate what solar panel system is right for you, its cost, and how much you can save by installing solar panels on your home.
Just enter a few details about your property and energy consumption, and you'll receive tailored results that make the process simple and straightforward.
Our solar panel calculator can give you a great overview of solar panel costs and savings in the UK. However, the cost and savings of solar panels will be affected by potential extras and installation costs, which vary by installer.
Our solar panel calculator will need your location, roof details, energy consumption, system preferences, financial information, and additional factors to estimate solar panel size, cost, and savings. Here’s how it calculates each metric:
If, after using our solar panel calculator, you’re still wondering how many solar panels you need or if solar panels are worth it, we highly recommend speaking to a solar specialist who can give you tailored advice.
GreenMatch’s solar panel calculator estimates the number of panels needed by taking into account your annual energy consumption, available roof space, and the wattage of typical solar panels.
The solar panel payback time is calculated by dividing the total installation cost by the annual savings on your energy bill. We also factor in potential increases in electricity rates to provide a more accurate estimate.
To estimate solar panel energy generation, consider the wattage of your solar panels and the average daily sunlight hours in your location. Multiply the panel wattage by the number of sunlight hours to get daily energy output in watt-hours.
