The sun number score is an indicator of your suitability for installing solar panels, with values ranging from 0 to 100. The magnitude of its value reflects whether or not you are suitable for installing solar panels, with higher values indicating better suitability for installing solar panels. The solar number score is usually judged from four aspects: building, climate, electricity cost and solar cost.
For the calculation of the solar number score, you need to judge from four aspects, you can use the Project Sunroof tool to calculate the solar number score of the roof, or you can ask a professional company to do the calculation.
Architectural Score: The architectural score is the most important aspect of the overall score and is worth 80 points, which is a combination of the size of the house and the solar panels, the degree of shading, the tilt of the house, and the orientation of the house. Generally speaking, when the score reaches 50, it is suitable for the installation of solar energy systems.
Climate Score: The climate score has a maximum of 8 points. Different regions have different weather conditions and different peak hours of sunshine in a day, which correlates with their latitude, altitude, etc. (places with high latitude or altitude have shorter peak hours of sunshine and correspondingly lower solar scores). The rainy season can be very long in some areas, and a full day of cloudy skies is not conducive to the absorption of light energy by solar panels. Also, some areas experience frequent hail, dust storms, etc., and these areas have a low climate score.
Score on Electricity: The main purpose of installing solar panels is to save money on electricity, and if the average price of electricity is higher in your area, the higher your solar energy number will be, which means that you are a good candidate for installing solar panels. It has a maximum score of 8.
Score on Solar Cost: The solar cost has a maximum score of 4, which is the smallest percentage, but it should not be ignored. The lower the cost of solar energy in your area, then the higher the solar number. It reflects your input cost, if the cost is low, the time to fill the cost in the later stage will be very short, and the harvest benefit will be bigger.
Comprehensive the above four aspects, the final score of each aspect will be added together, the total score can rarely reach 100 points, but when the total score is greater than 70, photovoltaic power generation will be able to bring you great benefits. Generally speaking, when the score reaches 60, installing solar panels is a good choice for you. But the choice of whether to install solar panels should not only be considered in terms of solar score, but also in conjunction with their own wishes.
Yes. This is just a judgment indicator, if your solar number score can only reach 50, you can also install solar system, just the benefit may be lower. But you can also choose to increase the benefits from a solar system through other means. The purpose of installing a solar system is to save money on your electricity bill, and you can also choose to install a solar system if you can make sure that you can still profit from it even with a low solar number.
when you consider whether you need to install a solar energy system, you will be able to calculate the sun number score based on the above to determine whether it is appropriate to install solar panels, and then make a choice based on your own wishes.
