Peak Hours For Solar Thermal Panels

Peak sun hours differ from hours of daylight.

Peak hours for solar thermal panels.

What are peak sun hours. Solar thermal collectors are classified by the united states energy information administration as low medium or high temperature collectors. To maximize the amount of sunlight your panels receive they should face south and be installed in an area where they will not be shaded by trees or other nearby buildings during the majority of daylight. Unfortunately the sun does not stay at one spot in the sky clouds do show up every now and then and then there is the whole sunrise and sunset thing we can t avoid.

A peak sun hour is the equivalent of the sun shining at an intensity for 1 000 kw per square meter for one hour expressed as 1 kwh m. Solar energy production estimate is done by using a variable peak sun hour psh times the power of the solar photovoltaic system in watts. A peak sun hour is an hour in the day when the intensity of sunlight is at least 1 000 watts per square metre. Just as in the chart above peak sun hours are.

The more peak sun hours a solar panel gets the more electricity it produces. Even in cloudy weather however solar panels can absorb solar energy to produce power though it will be at a significantly reduced rate compared to sunny days usually between 25 and 40. If you know the average daily peak sun hours for your location you can calculate the kwh your solar panels will make on a daily monthly and yearly basis. Because solar arrays are reliant on sunlight for the production of energy the amount of power coming from the same number and type of panels varies which is why san antonio s sun exposure matters.

Putting it all together. On average the state of kansas receives 5 79 daily peak sun hours. More information on maine green energy. While a 1kwp solar pv system is expected to produce roughly 850kwh of electricity each year in reality this figure will vary depending on the number of peak sun hours your panels experience.

Psh is not the same as hours of sunlight which is total hours from sunrise to sunset. Use our peak sun hours map to find out your average sun peak hours to determine if you can make the most of the solar power available to you. Ranking close to the middle for average peak sun hours among us states maine although to the far northeast of the country has amazing potential for solar power to flourish and provide the state with renewable and clean electricity so we can all enjoy the natural. In an ideal scenario for solar panels would receive direct sunlight 24 hours a day every day.

In maine the pine trees use the sun s energy to grow and flourish and so can you. The peak sun hour actually describes the intensity of sunlight in a specific area defined as an hour of sunlight that reaches an average of 1 000 watts of power per square meter. Solar thermal energy ste is a form of energy and a technology for harnessing solar energy to generate thermal energy for use in industry and in the residential and commercial sectors.
