Roof Mounted Solar Panels

For households interested in solar power, determining peak sun hours is a critical step in helping the system run as efficiently as possible.

WHAT IS A SUN HOUR?

A sun hour is the amount of time when a solar panel is receiving direct sunlight. Every hour of sunlight might not turn into sun hours for solar panels because of the angle at which solar panels are pointed. Fixed solar panels are set to an angle that absorbs the mid-day sunlight which is when the sun is at its brightest.

WHAT ARE PEAK SUN HOURS?

Peak sun hours occur when the sun offers photovoltaic production of 1,000 watts for each square meter of solar panel. Peak sun hours typically occur from noon to early afternoon when the sun is highest in the sky and most intense. Peak sun hours in Texas tend to increase during the summer months when the sun sits higher in the sky.

WHAT IS SOLAR INSOLATION?

Solar Insolation is the amount of solar radiation present on the earth’s surface. It is a measurement used to determine how much sun is shining on the Earth’s surface at any given time. While this measurement may not seem important, it is critical for determining how many solar panels you will need to power your home.

HOW TO CALCULATE PEAK SUN HOURS

Peak sun hours vary according to geographical location and the season so measurements only apply for a certain time a year. This insolation map shows that parts of Texas have some of the highest solar hours of the country, even through winter.

During our free on-site consultation at Cam Solar, we will run your home through a series of tests to find the observed solar insulation. Based on our 3D model we will be able to simulate how solar panels will perform on your roof.
