NREL's PVWatts ® Calculator Estimates the energy production of grid-connected photovoltaic (PV) energy systems throughout the world. It allows homeowners, small building owners, installers and manufacturers to easily develop estimates of the performance of potential PV installations.
Let’s walk through how to calculate the amount of solar power your roof can generate based on its size, orientation, and angle—as well as the solar panels you install. Find out what solar panels cost in your area in 2024.
Project Sunroof is a solar calculator from Google that helps you map your roof’s solar savings potential. Learn more, get an estimate and connect with providers. Enter a state, county, city, or zip code to see a solar estimate for the area, based on the amount of usable sunlight and roof space.
To help you adequately estimate the size of the solar system and the number of solar panels you can put on your roof, you can use the following Solar Rooftop Calculator. Further on, we have also calculated how many solar panels you can put on 300 sq ft to 5,000 sq ft roofs, and summarized the results in a big chart you can freely use:
As the photovoltaic (PV) industry continues to evolve, advancements in Rooftop solar power generation calculation have become critical to optimizing the utilization of renewable energy sources. From innovative battery technologies to intelligent energy management systems, these solutions are transforming the way we store and distribute solar-generated electricity.

6 FAQs about [Rooftop solar power generation calculation]
How much solar power will a new roof generate?
NREL estimates that an average of 3.3 million homes per year will be built or will require roof replacement—representing a potential of roughly 30 gigawatts (GW) of solar capacity per year. If even a small fraction of these new roofs had solar installations, it could have a significant impact on U.S. solar power generation.
How much solar power can a 2000 sq ft roof generate?
Let’s take a big 2000 sq ft roof as an example. Such a big roof has 1500 sq ft of viable solar panel area. If each of these viable square feet generates 17.25 watts of electricity, the combined 1500 sq ft will be able to generate more than 25kW per peak sun hour ( 25.875kW, to be exact).
How many solar panels can you put on a roof?
Number Of Solar Panel By Roof Size Chart. We have calculated how many of either 100-watt, 300-watt, or 400-watt solar panels you can put on roofs ranging from very little 300 sq ft roof to huge 5,000 sq ft roof, and summarized the results in a neat chart. This is a standard 10kW solar system, consisting of 25 400-watt solar panels.
How do you calculate solar generation potential?
We use the following assumptions to calculate solar generation potential: First, determine how many solar panels you can fit on your roof. Assuming all of the roof space you've got is usable for solar, that's 48 panels (850 square feet divided by 17.5 square feet per panel).
What is the minimum roof size for a 10kW Solar System?
This is a standard 10kW solar system, consisting of 25 400-watt solar panels. As we will see in the summarized chart below, the minimal roof size for a 10kW system is only 800 sq fr roof area (600 sq ft viable for solar panels due to 75% code consideration)
How to calculate solar panel output?
The first factor in calculating solar panel output is the power rating. There are mainly 3 different classes of solar panels: Small solar panels: 5oW and 100W panels. Standard solar panels: 200W, 250W, 300W, 350W, 500W panels. There are a lot of in-between power ratings like 265W, for example. Big solar panel system: 1kW, 4kW, 5kW, 10kW system.
