6 FAQs about [Sunshine hours calculator]
How do you measure sunshine hours?
A simpler method of measuring sunshine hours is to use a card system whereby sunlight is focused into a recording card. If the sunshine is greater than about 200W/m 2 a mark is burned onto the recording chart. The number of sunshine hours is determined as the number of hours during which the sun is shining.
How do I use a sun hours calculator?
Using this calculator is very simple. In the address field below, type your street address or city or zip code, or state and select the nearest match from the drop-down list. Then press submit button and you will be shown a table where the first row is the month and the second row is sun hours.
How do I calculate peak sun hours?
This next part is just for the solar nerds out there: When sizing a solar power system, peak sun hours should be calculated using Global Horizontal Irradiance (GHI), or Global Tilted Irradiance (GTI) at the tilt angle of the solar panels. Many people mistakenly calculate peak sun hours using Direct Normal Irradiance (DNI).
How much sun does a location get per day?
Using historical data, we can estimate the amount of sunlight we expect a location to receive per day. Then we can express this value in peak sun hours. So if, say, you live in Phoenix, AZ, you can expect to receive around 5.8 peak sun hours per day on average.
How do I calculate the worst-case peak sun hours?
If you want to calculate the worst-case peak Sun hours, pick the lowest entry in the table. That would be the month which receives the least amount of sun hours. If you are planning to buy a solar system to offset your electricity entirely, you might have to consider the worst-case Sun hours for your calculation.
How many kilowatt hours of Sun do you get per day?
Then we can express this value in peak sun hours. So if, say, you live in Phoenix, AZ, you can expect to receive around 5.8 peak sun hours per day on average. Put another way, on an average day, the sun will pump out 5.8 kilowatt hours of sunlight per square meter.
